The onshore Barua Field, near the southeast edge of Lake Maracaibo, is a highly faulted structure producing from the Eocene Pauji and Misoa intervals. This mature field has undergone significant depletion from approximately 30 wells since 1958. A classical, deterministic reservoir characterization study followed by reservoir simulation history matching was conducted. Prior to completing the his...

reservoir permeability is a critical parameter for characterization of the hydrocarbon reservoirs. in fact, determination of permeability is a crucial task in reserve estimation, production and development. traditional methods for permeability prediction are well log and core data analysis which are very expensive and time-consuming. well log data is an alternative approach for prediction of pe...

Subsurface formations that arise in the simulation of gas-injection processes for enhanced oil recovery may exhibit geometrically complex features with complicated large-scale connectivity. They must be included in simulations of flow and transport because they can fundamentally impact simulation results. However, to reduce computational costs, simulations are generally performed on grids that ...

The optimal CO2 storage operation requires high permeability in the near-well region order to keep it safe and cost-efficient. Nucleation growth of salt crystals driven by evaporation formation water into under-saturated (dry) super-critical streams result changes porosity near well-bore area. Permeability reduction is one main reasons for injectivity losses context saline aquifers. According r...

Non-Newtonian fluids may cause nonlinear seepage even for a single-phase flow. Through digital rock technologies, the upscaling of this non-Darcy flow can be studied; however, requirements scanning resolution and sample size need to clarified very carefully. This work focuses on Bingham fluid in tight porous media by pore-scale simulation CT-scanned microstructures sandstones. A bi-viscous mode...

We present a multiscale Bayesian method to reconstruct the permeability field of a binary medium. The reconstruction is conditioned on measurements of permeability and tracer test breakthrough times, observed at a limited set of locations. The medium consists of a spatially variable distribution of inclusions, which are too small to be individually resolved at the grid scale. The unknown inclus...

Research results for a five year project on the development of improved modeling techniques for nonconventional (e.g., horizontal, deviated, multilateral or “smart”) wells are presented. The overall program entails the development of enhanced well modeling and general simulation capabilities. The development and features of a new general purpose research simulator (GPRS) are described. The simu...
