Paper Number: SPE-212604-MS
... the impact of test speed on capillary pressure curve resolution. The tests were performed at net confining stress and at ambient conditions to evaluate if large differences were observed in results. Gravimetric measurements were simultaneously obtained to ensure data quality. Two different available imaging...

... ). As a result, the simulation technique has the advantage of being highly computationally efficient, enabling the modeling of capillary and buoyancy driven quasi-static flows in very high-resolution geological models (10-100s of million gridblocks) within minutes to a few hours. IP models fluid flow in a porous...

... and stress regime. To overcome these issues, an alternative solution was proposed, based on the implementation of Embedded Discrete Fracture Model methodology ( Li and Lee (2008 )). EDFM allows using a coarser grid resolution with respect to conventional LGR representation. Moreover, it accounts for fracture...

... of petrophysical data and geological facies. High-resolution micro to nano XCT images were integrated in the rock typing scheme. Those rock types were upscaled to the whole core level by linking the core litho-types to the plug data. The core litho-types (porosity and mineralogy) gave good representation...
