Dedicated to the memory of my beloved mother Emma Guzman and mysister Aura E. Florez-Guzman. AcknowledgmentsI would like to express my sincere appreciation for my advisor, Professor Mary F. Wheeler. She practically brought me from Venezuela for giving me the opportunity to attend graduate school at US. This ultimately opened new avenues to insert myself successfully in a country with a different language and culture. I will always appreciate this opportunity. She introduced me to topics such as mixed finite elements, discontinuous Galerkin schemes, domain decomposition and mortar methods. I am also thankful for her financial support, enthusiasm, and persistence on pursuing cutting-edge research.

“…Phillips and Wheeler [17,18] showed the theoretical convergence of 2-D models that pair both continuous (CG) and discontinuous Galerkin schemes for the displacements with mixed finite element (FE) spaces for flow. Sanhu and Wilson [19] published an 2 of 29 early FE application to 3-D consolidation that was reviewed by Yokoo [20]. Ghaboussi and Wilson [21] considered fluid's compressibility as well as the stability of CG schemes [22].…”

In this paper, we revisit well-established domain decomposition (DD) schemes to perform realistic simulations of coupled flow and poroelasticity problems on parallel computers. We define distinct solution schemes to take into account different transmission conditions among subdomain boundaries. Indeed, we examine two different approaches, i.e., Dirichlet-Neumann (DN) and the mortar finite element method (MFEM), and we recognize their advantages and disadvantages. The MFEM significantly lessens the computational cost of reservoir compaction and subsidence calculations by dodging the conforming Cartesian grids that arise from the pay-zone onto its vicinity. There is a manifest necessity of producing non-matching interfaces between the reservoir and its neighborhood. We thus employ MFEM over nonuniform rational B-splines (NURBS) surfaces to stick these non-conforming subdomain parts. We then decouple the mortar saddle-point problem (SPP) using the Dirichlet-Neumann domain decomposition (DNDD) scheme. We confirm that this procedure is proper for calculations at the field level. We also carry comprehensive comparisons between the conventional and non-matching solutions to prove the method’s accuracy. Examples encompass linking finite element codes for slightly compressible single-phase and poroelasticity. We have used this program to a category of problems ranking from near-borehole applications to whole field subsidence estimations.

“…Wang and Sterling (2007) performed numerical analyses named finite element to investigate the stability of a borehole wall during horizontal directional drilling in loose sand with an emphasis on the role of the filter cake in borehole stability. Muller et al (2007) performed wellbore stability analysis with a finite element program that incorporates coupled fluidmechanical effects and elastoplastic behavior of the rock. Alberto et al (Alberto and Sepehrnoori 2008) used commercial finite element software to investigate wellbore stability in multilateral open holes during drilling and production times and concluded that the most unstable region in multilaterals is the junctions (lateral wells).…”

Wellbore stability problems are known to cost the oil and gas industry billions of dollars each year. However, these costs can be significantly reduced through the application of comprehensive geomechanical models. This paper is relevant and is appropriate in the oil and gas industry. The objective of this paper is the comparison of four rock failure criteria, named the Mohr-Coulomb, Mogi-Coulomb, Modified Lade and Tresca yield criterion and to apply them to determine the optimum drilling direction and mud pressure. The stability models has been applied to a well located in Iran oil field and leads to easily computed expression for the critical mud pressure required to maintain wellbore stability. Then the finite difference method was used to show the validation and accuracy of predicted mud pressure and investigate the wellbore stability in different states of vertical, horizontal and deviated. The results showed that the Mohr-Coulomb and Tresca criteria estimate the highest minimum mud pressure required for wellbore stability while the Mogi-Coulomb and the Modified Lade criteria estimate the lowest minimum mud pressure. Nevertheless, the mud pressures predicted by all these four criteria are acceptable and can be used.
