1. New computational methods for study of drilling mechanics and cuttings transport in boreholes

1.1 DEM-FEM and PFEM approaches for study of drilling mechanics

Modeling and simulation of drilling problems in oil and gas industry is a challenging computational task. Some relevant problems of practical interest to accurately predict are multi-fracture of soil and rock at the drill bit, the wear of the drilling tools and the transport of cuttings within the drill pipe immersed in a mud-type flow up to the pipe surface.

CIMNE has developed several techniques to study ground drilling and excavation processes.

The two most promising methods are:

- Coupling of the discrete element method (DEM) and finite element method (FEM) [1-5]. This technique combines the discrete element method (which models the continuous solid in a separate set of simple geometric shapes) with conventional finite element method. We have developed at CIMNE a local constitutive modal for the DEM adequate for the non-linear analysis of soft and hard soils. An innovative combined DEM-FEM procedure has been applied for simulating multi-fracture of material at the drill bit. This allows the study of multi-fractures in granular media process (including land and rocks) with DEM modeling, while the unbroken continuum is modeled with FEM. The DEM-FEM technique has been applied successfully to the study of many problems in ground engineering, including processes of excavation, tunneling, drilling and dredging in soils and rocks, and to ground deformation by explosions.

An interesting aspect of the DEM-FEM technique is that it allows the study of the effect of wear on the cutting tools during the excavation process.

- Particle finite element method (PFEM) [6.7]. That PFEM is a very powerful method to study cutting, excavation and dredging of soils and rocks. In addition to keeping track of the progress of the excavation front, PFEM can predict the deterioration of the cutting tools as the excavation progresses.

Current research work focusses in coupling the DEM-FEM approach with PFEM. This will result in a new particle discrete finite element method (PDFEM). This novel technique can become the most general method for the study of the ground and adjacent structures in multi-fracture situations such as excavation, drilling, dredging, explosions, tunneling, and others.

1.2 Analysis of cuttings transport problems

Cuttings transport (hole-cleaning) process is a challenging issue associated with efficiency of wellbore drilling process. Cuttings transport process involves complex interaction between cuttings, drill pipe, wellbore and drilling mud. To understand the cuttings transport in a wellbore advanced computational techniques such as discrete phase modeling, discrete element modeling (DEM) are essential. The major focus of this work is on utilizing Particle Finite Element Method (PFEM) to understand the cuttings behavior locally in critical sections of wellbore.

The PFEM technique uses an updated Lagrangian description to model the motion of nodes (particles) which are a conceptual representation of an underlying continuum domain (either a fluid or a solid). A mesh connects the nodes defining the discretized domain where the governing equations for the continuum problem are solved as in the standard FEM. The PFEM technique allows to model complex particulate flow problems. In this work PFEM is utilized to model the transport of cuttings in vertical and inclined wellbores.

These developments have been carried out under different R&D projects in national and EC programming in collaboration with construction companies.

1.3 Computational methods for analysis of fracking processes

The DEM-FEM technology developed by CIMNE is particularly suitable for application in sites with multi-fracture problems caused by explosions or by deformations due to rock blasting situation, geological/geotechnical failures or slides or to adjacent drilling.

The DEM-FEM technology is currently being use at CIMNE for analysis of hydraulic fracturing and pulse-controlled fracking problems in cooperation with several drilling and oil and gas companies worldwide.

1.4 Drilling salt layers

The DEM-FEM and PFEM techniques developed by CIMNE are directly applicable to the study of drilling problems in salt layers. In both cases the correct modeling of ground layers and saline strata’s mechanical properties is critical.

CIMNE does not have a specific experience in applying this technique to drilling of salt layers. However, CIMNE has applied the above methods to the study of land drilling in typical geotechnical engineering surveys.

2. New computational methods for analysis of sloshing of fluids in tanks

CIMNE has developed advanced numerical methods for the study of the sloshing phenomenon in tanks containing liquids, such as oil tanks and transportable LNG ships.

CIMNE has developed two methods to study the sloshing problem:

- Particle finite element method (PFEM). A technique allowing full Lagrangian modeling of the fluid that accurately reproduces the effect of sloshing and its interaction with the walls of the tank taking into consideration its deformation.

- Finite Element Method coupled with free surface techniques based on the volume of fluid (VOF) technique. The method allows also the reproduction of the sloshing phenomenon, although the accuracy is lower than with PFEM, if the effect of sloshing coupled with the tank deformation is taken into account.

3. Innovative computational method for the study for the sea-keeping performance and stability of ships in large waves

3.1 Ship hydrodynamics

CIMNE has experience in the application of advanced numerical methods in the study of the dynamics of structures at sea. Both advanced finite element method (FEM) and the Particle Finite element Method (PFEM) have been developed and applied in this field to study the hydrodynamics of: ships at sea with waves; action of the waves on concrete blocks, and / or perforated blocks at port docks; perforated block dynamics during their placement at sea; erosion processes in submerged structures at sea; deformation of offshore platform structures under wave action; kinematics of wind turbines at sea. These applications have been carried out in the framework of different RTD projects with industry.

3.2 New computational methods for study of the ship-ice interaction

The Particle Finite Element Method (PFEM) developed in CIMNE is a very promising technique for the study of the dynamics of ice blocks floating or submerged in seawater and their interaction with each other and with adjacent deformable structures. PFEM also allows the study of multi-fractured ice blocks during their interaction with icebreakers, boat hulls or other items impacting ice. The method allows also taking into consideration ice at different temperatures, including its eventual melting in water.

Most of the research work carried out at CIMNE in these fields makes use of the codes Tdyn (www.compassis.com) and PFEM (www.cimne.com/pfem).

5 New computational method for analysis of multiphase particulate flows

5.1 Multiphase gas-liquid-solid flows

CIMNE has developed advanced computation methods for the study of flows with different properties (heterogeneous or multi-fluid flows) which can contain solid particles of different sizes. These type of flows are typical of fluid-soil-structure interaction situations , environmental flows, biological flow, melting and burning of objects in fire and some industrial forming processes, among others.

The computation methodology is based on the Particle Finite Element Method (PFEM, www.cimne.com/pfem). The PFEM solves heterogeneous continuous media (including multi-particle flows). The continuous medium is modeled as a set of particles whose motion is tracked over time. The equations of continuum mechanics are solved by the finite element method (FEM), creating a mesh over a cloud of points in each instant of time. The PFEM allows studying the movement of solids (rigid or deformable) inside multiphase fluids, including the effect of frictional contact between the solids, and between these and the fluid.

The PFEM uses an updated Lagrangian description to model the motion of nodes (particles) in both the fluid and the solid/structure domains which are modelled as a single continuum (SC). Nodes are viewed as material points which can freely move and even separate from the main analysis domain representing, for instance, the effect of physical particles or water drops. A mesh connects the nodes defining the discretized domain where the governing equations for the SC problem are solved as in the standard FEM. The PFEM allows for frictional contact conditions and surface erosion at fluid-solid and solid-solid interfaces via mesh generation. A new technique to model the motion of particles of different sizes in a fluid has been recently developed at CIMNE.

The PFEM has been successfully applied to a number of particulate flow problems such as the motion of multiphase fluids in porous media, erosion of earth dams in overtopping situations, the motion of mud particles and floating/submerged bodies in tsunami flows, the impact of slurry flows on structures , the erosion due to water streams in river beds and slopes, erosion and particle transport in excavation and drilling problems in the construction and oil/gas industries, melting and dripping of polymer objects due to fire and simulation of industrial forming problems involving particulate flows ,among others.

5.2 Emulsions

The particle finite element technique (PFEM, www.cimne.com/pfem) developed in CIMNE is particularly suitable for simulation of emulsions. The PFEM has been applied successfully in CIMNE to study the behavior of two immiscible liquids in a more or less homogeneous mixture. The method allows simulation of one liquid’s dispersion in the other liquid, obtaining at each instant in time the evolution of the particles in both liquids through Lagrangian formulation.

PFEM can be applied to stable and unstable emulsions, such as flocculation, wherein particles form a mass; cremation, wherein particles are concentrated in the surface of the mixture (or bottom, depending on the two phases relative density) while remaining separated, and coalescence wherein the particles melt and form a liquid layer.

5.3 Modelling and simulation of the geotechnical behavior of salt formations

CIMNE has developed advances computational tools for the study of geo-technical and geology problems, including, among others, the behavior of saline formations, using the Particle Finite Elements Method (PFEM). Some applications of these developments include:

- Study of heterogeneous liquid leaks in porous media, including erosion and eventual sliding of granular media.

- Study of diapirs formation.

The potential of the PFEM for the study of saline formation is promising. Specifically PFEM allows modeling the behavior of salt formations in different stages, taking into account, for example, the effect of adjacent perforations, explosions, or the possible flow of fluid through the saline formation.

6. Decision support system for the enhanced prediction and management of oil spills

CIMNE has substantial experience in the development of numerical methods and expert systems for marine spill modeling and simulation and for prediction of spill evolution in the ocean in different weather and ocean conditions.

Concerning the spill simulation, CIMNE has developed different methods:

a) 3D simulation of the spill transport process, including convection effects (currents and wind), diffusion and vertical dispersion, evaporation, emulsification, etc.. The procedure is based on the Eulerian equations solution for spill transport in water using the finite element method.

b) Lagrangian simulation of the spilled particles transport by stochastic methods. The procedure is based on a Lagrangian particle layout over a three dimensional mesh.

c) Simulation of the transport process of the spill over large areas in the ocean. The procedure is based on solving the transport equation in a fluid medium in which the scope of velocities is known, using the finite element method coupled with fluid volume techniques. The method may be used in 3D. However, in many cases it is valid to use the formulation called 2.5D. This technique is based on a hypothesis of the spill’s behavior in the vertical direction, which allows a 2D discretization of the sea domain in which the spill spreads.

d) Integration of an expert system for decision support (DSS: Decision Support System) to predict near-real-time evolution of the spill. The DSS integrates sea conditions and weather, and the evolution of the spill simulation with artificial neural networks algorithms (ANN). Through adequate training of the ANN it is possible to predict the evolution of the spill during the hours following the spill for different sea conditions.

e) Development of a web interface on a GIS environment, able to integrate the models and above mentioned systems.

The methods referred to are implemented in GPU processors, allowing in many cases operating in real time.

CIMNE’s developments in the field of marine spills have been carried out in the framework of different national and EC conducted in collaboration with companies and organizations specializing in the subject.

7. Modeling and simulation of heterogeneous reactors

CIMNE has experience in the modeling of reactor mixing processes in the chemical and oil industry. In that field it has developed its own simulation methods based on the finite element method (FEM).

The computational method developed at CIMNE allows modeling of the flow in reactors provided with slow rotating agitators or with substantial rotation speeds, depending on the potential applications. It is also possible to incorporate, in the geometric model of the body, elements fixed to the chemical reactor, such as breakers to increase the flow turbulence. This is possible due to the combination of a rotary computational domain attached to the reactor blades, with another fixed domain containing the possible obstacles in the reactor’s body.

The model also allows for multiphase flow modeling as well as for the determination of the reactor’s fluid free surface. Both issues are addressed by using a level set function, which allows following the interfaces between fluids and the free surface, if it exists.

In all the problems approached, the finite element methods developed are based on so-called stabilization techniques, whose purpose is to allow the modeling of extreme regimes (large rotations, small viscosities, large reaction coefficients should such exist, etc.).

8. CIMNE CFD CODES

CIMNE has developed various CFD codes to simulate specific problems in fluid dynamics of different complexity, including multi-phase flow, fluid-structure interaction, fluid-structure interaction-terrain combustion reaction, and other.

Many of these developments are integrated in a commercial code (Tdyn) which is sold worldwide by CIMNE’s spinoff technology based company: Compass Ingeniería y Sistemas SA (www.compassis.com).

CIMNE’s most recent developments and applications, including multiphase flow simulation with solid deposits are based on the finite element technique particles (PFEM) recently developed by CIMNE. This CFD code (based on PFEM) is still under development and it incorporates PFEM capabilities in the Tdyn code.

There is therefore the possibility of using the Tdyn commercial code (which includes a wide range of applications in fluid dynamics) as well as other last generation CIMNE’s R & D codes (such as PFEM based codes) versions of which have not yet reached the market.

Concerning PFEM’s ability to simulate deposition processes, it is highlighted that PFEM allows the simulation of solid depositions and following the track of the particles during deposition, including changes in the fluid’s geometry. This is possible by using the Lagrangian formulation PFEM, which monitors the movement of both solid particles and fluid, solving the continuum mechanics equations (for both the fluid and the solids contained) in each step of time through the finite element method.

CIMNE has successfully applied the PFEM technique to the study of particle depositions problem in fluids in tanks.

CIMNE is willing to contribute its existing computing technology to specific collaborative developments in this line of R & D.

Marketing of CIMNE’S CFD codes

COMPASS and CIMNE are open to consider different ways to market CFD codes developed in collaboration.

Also CIMNE and COMPASS will provide special conditions for use of these codes as part of R+D agreements.

CIMNE and COMPASS are also interested in the commercial exploitation of new developments of CFD codes as a result of collaborative R&D projects.

9. OVERVIEW OF THE ACTIVITIES OF THE INTERNATIONAL CENTER FOR NUMERICAL METHODS IN ENGINEERING (CIMNE)

9.1 Overview of CIMNE

The International Center for Numerical Methods in Engineering (CIMNE) is a research organization created in 1987 at the heat of the prestigious Technical University of Catalonia (UPC) as a partnership between the Government of Catalonia and UPC. The aim of CIMNE is the development of numerical methods and computational techniques for advancing knowledge and technology in engineering in applied sciences.

CIMNE’s headquarters are located at the heart of the Technical University of Catalonia (UPC) in Barcelona. CIMNE has also premises at different buildings in several campus of UPC . CIMNE has also offices in Spain in Madrid, Terrassa and Ibiza. In 2005 CIMNE started its international expansion and since then has created the following international branches: CIMNE Latinoamerica (Non profit Foundation in Santa Fe, Argentina); CIMNE USA (Non profit Corporation in Washington DC, USA); CIMNE Singapore (Non profit Corporation in Singapore).

CIMNE employs some 200 scientists and engineers who work in the different offices of CIMNE around the world (Barcelona, Madrid, Washington DC (USA), Singapore, Santa Fe (Argentina), Beijing and Shanghai (China). CIMNE has also established a network of 28 Classrooms and Joint Labs in partnership with Universities in Spain and 10 Latin American countries.

The research and technology development (RTD) activities of CIMNE cover a wide spectrum of topics ranging from classical engineering fields such as civil, mechanic, environmental, naval, marine and offshore, food, telecommunication and bio-medical engineering, computer sciences and applied sciences such as material sciences bio-medicine, computational physics, nature, social and economic sciences and multimedia sciences, among others.

Over the list 25 years CIMNE has taken part in over 2000 RTD projects in cooperation with some 500 enterprises, universities and research centers worldwide.

The RTD activities of CIMNE are complemented by education and training activities via Master Courses, short courses and seminars, and CIMNE Coffee talks. CIMNE scientists supervise doctorate students in cooperation with several universities in Spain and worldwide.

The publication Department of CIMNE publishes books, monographs, research reports and technical reports. The Congress Department of CIMNE organizes international conferences and workshops in the different areas of CIMNE. It has organized 140 conferences since 1987.

CIMNE has a vocation for transferring the scientific and technical outputs from RTD projects to the industrial sector. This is effectively carried out in cooperation with companies from different sectors that exploit and market the CIMNE technology. CIMNE has actively promoted the creation of spin-off companies, some of them totally or partially owned by CIMNE, that play an important role in the industrialization and exploitation of CIMNE technology.

CIMNE maintains close cooperation links with many universities and RTD centers in the field of computational engineering and sciences worldwide. CIMNE has access to the computing facilities of several supercomputer centers in Spain and Europe.

CIMNE has been identified as one of the International Centers of Excellence on Simulation-Based Engineering and Sciences in a recent National Science Foundation (NSF) report [Glotzer et al., WTEC Panel Report on International Assessment of Research and Development in Simulation Based Engineering and Science. World Technology Evaluation Center (wtec.org), 2009].

The following sections briefly explain the strategy of CIMNE for education, dissemination research and technology transfer. We also describe the main academic and scientific activities, as well as the RTD lines of the CIMNE departments and the spin-off companies and products developed at CIMNE.

9.2 The cycle of ideas

9.2.1 From ideas to prototypes

The mission and activity of CIMNE can be clarified if we examine what we call the Cycle of Ideas. Figure 1 shows a scheme of the transit of an idea, from the instant it originates until it is transformed in an industrial and commercial success. Similarly as it happens in other biological environmental cycles (the water cycle or the cycle of plants, for instance), the cadencies and tempos are very important in the cycle of ideas.

Figure 1. The Cycle of Ideas

Ideas (and here we basically refer to scientific advances) usually originate in university environments, where many professionals have the mission of thinking, studying, investigating and eventually discovering new areas of knowledge. The idea (the new discovery) would be equivalent to a seed, in the sense that even being very important (essential) it is far from becoming a fruit.

The idea matures in its "tour" by the first quadrant of the Cycle (the University) until it produces tangible results (thesis, papers, computer programs, physical devices, etc.). These "results", if they are not filed and protected, can be easily lost. This leads to undesirable repetitions or duplications.

What to do then with the results of an idea? The best is that they can evolve until they reach the level of a prototype; i.e. until they became something (a software code, a system, a device, etc.) that works in a contrastable manner in the hands of a person different from the author. The transit of a result to a prototype is not a trivial one and it demands an organization, efficient and capable staff and resources that are usually far from the ordinary means of a university group. The best alternative is, therefore, that the idea follows its route on specialized institutions, adjacent to the university, such as CIMNE, with the specific mission to transform knowledge into tangible things (prototypes) in cooperation with other RTD organizations worldwide.

9.2.2 From prototypes to product and market

Can a prototype be released into the market with a guarantee of success? The answer is (probably) no. The distance between a prototype and a product is typically a long one. Getting a product is an objective in itself and mixing it up with RTD tasks is not advisable and leads to frustrations. Products should be developed in companies where specialists devote their time and talent exclusively to obtaining, validating and documenting a product, as well as to defining the marketing plan.

Once a product has finally reached the market, it would enter into the last quadrant of the Cycle of Ideas. There the objective is commercial success. In order to reach that, the company should establish the necessary alliances around the world. The Cycle ends up with the return of a part of the profits from the marketing of the product to the place from where the idea originated (the University).

Clearly, the "rotation speed" of the idea around the Cycle can be increased with the help of funding from external public and private sponsors, as it is metaphorically shown in the figure. These concepts are in fact very simple. However it is typically very difficult to put them into practice. Creating and transforming ideas and knowledge into useful products is the key mission of CIMNE.

9.3. Training and dissemination of research

9.3.1 Courses and Seminars

CIMNE hosts since 1989 a Master Course on Numerical Methods in Engineering in presential mode (in English) and in the e-learning mode (in Spanish). Both the Master and Ph.D. degrees are awarded by UPC. Since 2007 CIMNE is also the Secretariat and Managing organization of a Master in Computational Mechanics sponsored by the Erasmus Mundus Programme of the EC jointly organized by UPC and the Universities of Swansea (UK), Nantes (France) and Stuttgart (Germany).

CIMNE organizes regularly short courses (20-30 hours) on selected topics in computational engineering delivered by distinguished scientists and engineers. Some 25 research seminars of 1-2 hours duration are also organized annually at CIMNE.

The CIMNE Coffee talks are 40 minute presentations delivered by an invited scientist (typically a CIMNE researcher) with the aim of presenting the advances on a specific research line. The talks are preceded by coffee and pastry and are closed by an informal debate between all attendants. Some 30 CIMNE Coffee talks are annually held at the different CIMNE premises.

9.3.2 International Conferences

CIMNE is a regular organizer of international conferences on advanced topics of computational engineering and sciences. CIMNE has organized 105 conferences since 1987. The full list can be found in www.cimne.com.

9.3.3 Publications

CIMNE has an active policy for publication and dissemination of the outputs derived from the research activities (total of 550 papers since 1987). Apart from the publication in scientific journals, CIMNE has its own Publication Department which publishes regularly Books (130), Monographs (193), Research Reports (370) and Technical Reports (625). Number in parenthesis indicates the titles published by CIMNE since 1987. The list of the publications can be found in www.cimne.com.

9.3.6 The CIMNE Classroom Network

CIMNE Classrooms are physical spaces for cooperation in education and RTD activities created jointly by CIMNE and one or several universities around the world. The CIMNE Classrooms carry out training activities at graduate and postgraduate levels and RTD projects in cooperation with enterprises. Currently there are 24 CIMNE Classrooms in the following countries: Spain (6), Argentina (4), Mexico (3), Venezuela (3), Colombia (2), Brasil (2), Cuba (1), Chile (1), Perú (1) and El Salvador (1). For more information visit www.cimne.com.

9.4 RTD activity

9.4.1 Holistic view of CIMNE activities

The research and technological development (RTD) mission of CIMNE has evolved over the years towards providing comprehensive solutions for solving problems that affect human beings. This can be achieved by integrating existing knowledge in a particular field with quantitative information emanating for prediction methods (i.e. computational-based techniques) and experimental measurements. The link between these four concepts: the problem to be solved, computational methods, experimental methods and existing knowledge is well represented by the so-called magic tetrahedron shown in Figure 2.

Each of the nodes in the tetrahedron is connected to the other three by lines that represent information pipelines (possibly internet). The intensity of the flow along the lines that interconnect two nodes would vary depending on the requirements for solving the problem.
