Application of Machine Learning in Different Stages of Oil Reservoir Development
Geological and oilfield big data is exponentially expanding. The traditional methods used to identify reservoirs and predict production cannot use historical information and new data effectively. The processes of well logging interpretation and pipeline non-destructive examination (NDE) are time …

A New Method for Determining Average Reservoir Pressure from a Single Well Buildup Test
… buildup test in a multiple well unsteady state oil reservoir, can give the true average reservoir pressure without prior knowledge of drainage area shapes. To sUbstantiate the accuracy of the model, test runs were made on regularly shaped reservoirs for which the solutions to the pressure …

Exploring transport and phase behavior in nanoporous carbon materials
… membrane fabrication, single-molecule detection, oil reservoir modeling, and drug delivery. While transport and phase behavior in larger nanopores (>50 nm) approach bulk or are well-described by continuum models, much less is known about much smaller nanopores where the diameter of the pore is on …

Optimum Timing for CO2-EOR After Waterflooding and Soaking Effect on Miscible CO2 Flooding in a Tight Sandstone Formation,
… contrast between the injected CO2 and the crude oil. The oil recovery is limited after CO2 BT, which is attributed to the gas channeling problem. In continuous CO2 tertiary flooding, the previously injected water helps to control the mobility of the subsequently injected CO2. On the other hand, …

Convergence of material balance in mathematical simulation of petroleum reservoirs
… of error in prediction of fluid migration in the reservoir. However, this condition is not sufficient to guarantee accuracy of the simulation, since inaccuracies are introduced by truncation errors, machine round-off errors, and by the use of finite difference approximations to represent nonlinear …
