Abstract A new approach for numerical modeling of a set of compositional dynamic models of oil and gas fields coupled by the same surface network is considered. A unified coupled system of equations is constructed to jointly model reservoir and surface network processes in the method proposed. A new integrated model “reservoir-well-surface network” is a …

Abstract Significant acceleration of the calculations used to create three-dimensional geological and hydrodynamic models is discussed. Detailed 3D models of large and giant reservoirs requires significant computing power for their creation. All available seismic, geological and hydrodynamic data on the oil and gas field, which must be taken into account in a detailed model, require …

Abstract Reducing fracture/well spacing and increasing hydraulic fracture stimulation treatment size are popular strategies for increasing hydrocarbon recovery from multi-fractured horizontal wells (MFHWs). However, these strategies can also increase the chance of fracture interference, which not only can negatively impact the overall production, but also introduce complexities for production data analysis. To analyze the production …

Abstract Multi-fractured horizontal wells (MFHWs) have enabled commercial production from low-permeability oil reservoirs but oil recoveries remain exceedingly small using the primary recovery scheme. As a result, operators have investigated the use of solvent (gas) injection schemes, such as huff-n-puff (HNP), to improve oil recovery. Laboratory experiments simulating the HNP process have been proposed to …

Abstract This paper deals with the issues related to the modeling of non-equilibrium phase transition in isothermal compositional models. Based on a real case of oil and gas field in the Middle East, the importance to take into account the effects of thermodynamic non-equilibrium are demonstrated with the help of mathematical models proposed earlier. Theoretical …
