T1 Influence of Fracture Tip on Fluid Flow Displacements JF Journal of Porous Media JO JPM YR 2009 FD 2009-04-17 VO 12 IS 5 SP 435 OP 447 AB Understanding multiphase fluid flow in fractured rocks is essential for designing and optimizing hydrocarbon recovery processes. The fluid flow interactions between the fractures and the matrix have a significant impact on displacement processes. This work focuses on multiphase flow in the presence of a fracture tip. It studies two-phase fluid flow (water-il) displacements in layered Berea sandstones that have been artificially fractured with a single extensional fracture perpendicular to the natural layers. Two experiments were considered in this work. In the first experiment, the fracture was induced at the inlet end of the sample and it spanned the first third of the core. Thus, the diverging flow at the tip of the fracture was studied. In the second experiment, the fracture was induced at the outlet end of the sample and it spanned about one-third of the core. The impact of the fracture tip on fluid flow was studied in both experiments. The temporal and spatial saturation distributions of the two cases were determined using x-ray computed tomography, CT. The 4D-CT experimental data and recovery information were used as the basis for simulation in an effort to determine the interaction of the fracture-matrix environment with multiphase flow. At the tip of the fracture, the two experiments showed different fluid flow patterns. PB Begell House LK https://www.dl.begellhouse.com/journals/49dcde6d4c0809db,54e7056e0c6b6dd0,5f97232201e7fdc0.html
