Diffusion in fractured reservoirs, unlike in unfractured reservoirs, can affect significantly the efficiency of gas injection in oil reservoirs and recycling in gas/condensate reservoirs. The physical diffusion, similar to gravity, results in the change of the path of the injected gas species from the fractures to the matrix, giving rise to late breakthrough. In this work, we present, for the f...

Abstract The Gulf of Suez in Egypt contains more than 80 conventional oil fields with reservoirs from Precambrian up to Quaternary age. To date, these have all been resources. This abstract will take part the sequence within Petrogulf Misr Company and present a work process for unconventional resource assessment Brown Limestone formation one areas. is Late Cretaceous Pre-rift mega succession pl...

for the characteristics of horizontal fractures in shallow low-permeability oil layers after hydraulic fracturing in multilayer reservoirs, horizontal fractures are taken equivalent to an elliptical cylinder with the reservoir thickness using the equivalent permeability model; then, upon the elliptic seepage theory, the seepage field which has led by a vertical well with horizontal fractures is...

The carbonate reservoir plays a pivotal role in conventional oil and gas reservoirs. However, due to limited knowledge of fluid flow characteristics fractured-vuggy formations (vuggy means small medium-sized cavity inside rock), high efficiency development remains challenging. In this study, the similarity principle is utilized design two-dimensional visual model based on geological data inject...

Within the Lower Carboniferous limestones in boreholes of Poederlee, Heibaart and Turnhout (Campine Basin, NE-Belgium), open veins partially cemented by calcite dolomite are considered important with regard to geothermal reservoir potential these limestones. Based on a detailed petrographic analysis, stable carbon oxygen as well clumped ?47 isotope analysis U/Pb age dating, formation conditions...

Introduction: Carbonate production is thermodynamically inhibited under low-pH conditions. More specifically, in most terrestrial environments, neither abiotic or biotic pathways favor the production of carbonates below a pH of ~4.5. However, carbonate minerals have been recognized associated to extremely acidic environments of Río Tinto, Spain. The mineralogical similarity of these deposits at...
