Abstract Carbonate gas reservoirs in China are rich reserves. In the development process, there many reserves with low permeability, efficiency and recovery degree. It is difficult to stabilize well production prolong its life cycle. Under condition of original water saturation ( Sw ) 0%, 20%, 40%, 55% 65%, respectively, physical simulation experiment depletion was carried out by using long cor...

efforts to enhance oil recovery through wettability alteration by nanoparticles have been attracted inrecent years. however, many basic questions have been ambiguous up until now. nanoparticlespenetrate into pore volume of porous media, stick on the core surface, and by creating homogeneouswater-wet area, cause to alter wettability. this work introduces the new concept of adding znonanoparticle...

porosity is considered as an important petrophysical parameter in characterizing reservoirs, calculating in-situ oil reserves, and production evaluation. nowadays, using intelligent techniques has become a popular method for porosity estimation. support vector machine (svm) a new intelligent method with a great generalization potential of modeling non-linear relationships has been introduced fo...

We develop a numerical simulation of the global biogeochemical cycles of carbon that works over time scales extending from years to millions of years. The ocean is represented by warm and cold shallow water reservoirs, a thermocline reservoir, and deep Atlantic, Indian, and Pacific reservoirs. The atmosphere is characterized by a single carbon reservoir and the global biota by a single biomas...

the goal of this laboratory study is to investigate the effect of pore shapes on seismic wave velocities in carbonate rocks under reservoir conditions. in this research, 41 core plugs of carbonate rocks from oil fields of the southwest of iran were prepared. the compressional and shear wave velocities were measured in both dry and brine saturated samples under several pressures especially reser...

a typical iranians carbonate matrix block surrounded by an open fracture was modelled in order to understand the fracture-matrix interaction and how to model the interaction best. this was modelled by using a fine-scaled eclipse model in the single porosity mode . the model was extended to a stack of 6 matrix blocks to understand block-to-block interaction under gas injection scenarios. results...

a typical iranian carbonate matrix block surrounded by an open fracture was modeled in order to understand the fracture-matrix interaction and realize how to model the interaction best. the modeling was carried out by using a fine-scaled eclipse model in the single porosity mode (the fractures were explicitly modeled). the model was extended to a stack of 6 matrix blocks to understand block-to-...

Since carbonate reservoirs develop pores and fractures have a complex formation pressure system, overflow even blowout seriously threaten the exploration development of these kinds reservoirs. According to characteristics fractured-vuggy reservoirs, field monitoring identification method for has been developed. This is based on top-down logic framework early identification, combined with optimi...

Abstract This paper aims to gain new insights into clastic buried hill reservoirs. For this purpose, the Permian sandstone reservoirs in Upper Shihezi Formation, Gubei low hill, Jiyang Depression, was taken as object. Referring evolution histories of and tectonics, diagenesis its coupling with tectonic activity were investigated, aid techniques like core observation, casting sheet scanning elec...
