The gas-assisted gravity drainage (GAGD) process is designed and practiced based on gravity drainage idea and uses the advantage of density difference between injected CO2 and reservoir oil. In this work, one of Iran western oilfields was selected as a case study and a sector model was simulated based on its rock and fluid properties. The pressure of CO2 gas injection was close to the MMP of th...

This paper reports regional drainage patterns observed during the development of surface drainage maps from aerial photographs of sev­ eral counties in Indiana. This drainage mapping is a part of the current highway research program at Purdue University. The airphotos used in this work were taken during 1937-1943 in connection with the United States Department of Agriculture map program. The pr...

High concentrations of acid were found to arise from the interaction between molten rock and seawater at the shoreline of Kilauea Volcano, Hawaii. A series of field samplings and experiments show that the acid was derived from two sources: the release of magmatic volatiles and water–rock reactions. Although the bulk of the magmatic volatiles (CO2, H2O, and SO2) are vented at Puu Oo cinder cone ...

Using a proteomic approach, we searched for protein changes dependent on Rho-associated kinase (ROCK) during phorbol-12-myristate-13-acetate (PMA)-induced apoptosis. We found that heterogeneous nuclear ribonucleoprotein C1 and C2 (hnRNP C1/C2), two nuclear restricted pre-mRNA binding proteins, are translocated to the cytosolic compartment in a ROCK-dependent manner in PMA-induced pro-apoptotic ...

core flooding experiments were conducted with the objective of evaluating near miscible surfactant alternating co2 injection and the effect of surfactant concentrations on gas-oil and water displacements in porous media. the core samples were provided from a low permeability mixed wet oil reservoir at 156 °f and 1900 psia. in addition, very few studies of surfactant adsorption on carbonate mine...

Acid mine drainage (AMD) is a worldwide pollution problem of watersheds. In addition to toxic metal(oid)s and acidity, many elements economic interest are released into the environment, which make AMD potential strategic secondary source these such as rare earth (REE). Despite importance metals, their origin in still uncertain. Recent hypotheses suggest preferential leaching REE-enriched minera...

We investigate the influence of fluid rheology on flow in a finite rock fracture with vertically varying aperture and subject to competing drainage mechanisms due permeable substrate draining edge. The is release volume fluid, either Newtonian, Ostwald–deWaele, or Herschel–Bulkley. Hele–Shaw analogy between lubrication seepage flows allows extending our results porous medium permeability porosi...
