We perform single-phase and two-phase flooding on Edwards Brown rock samples. The injection was of seawater or CaCl2 brine, at successive salinities 0.63, 0.21, 0.07, 0.05, 0 mol/L (distilled water). For brine experimental run, no significant fines migration permeability decrease is observed. distilled water found to bring about the highest concentration produced most decrease, with ultimate be...

Identifying the mechanisms that control formation of compaction bands is high interest in reservoir mechanics since these structures may drastically affect performance geosystems operations. Considering difficulty to identify carbonate samples tested laboratory, Digital Volume Correlation technique applied here and proves be a relevant method. X-Ray Computed Tomography (XRCT) images Saint-Maxim...

High molecular weight polymers are widely used in oilfield applications, such as chemical enhanced oil recovery (cEOR) technique for hydrocarbon recovery. However, during flow a porous rock, polymer retention is usually major challenge, it may result the decrease of concentration or lead to plugging pores with significant permeability reduction and injectivity loss. Hence, an understanding mech...

pillow lavas are locally conspicuous. A unit consisting of dark, thinly bedded sandstone and siltstone, lccally ranging to several hundred feet thick, is lowermost in the exposed section. The middle division consists of about 3,500 feet of mixed andesi.:e and basalt volcaniclastic rocks ~ lahar, tuff breccia, volcanic sandstone, and conglomeratic beds which rest on relatively thin, fossiliferou...
