Tracer testing in fractured reservoirs has long been limited by the availability of unique and unambiguous tracers. In this study, we introduce the concept of using thermophilic microorganisms and DNA barcoding techniques for fractured reservoir characterization. On the one hand, thermophilic microorganisms have the potential of thriving in the extreme environment of geothermal and oil reservoi...

Efforts to enhance oil recovery through wettability alteration by nanoparticles have been attracted in recent years. However, many basic questions have been ambiguous up until now. Nanoparticles penetrate into pore volume of porous media, stick on the core surface, and by creating homogeneous water-wet area, cause to alter wettability. This work introduces the new concept of adding ZnO nanopart...

Hydrochloric acidizing is a routine operation in oil fields to reduce the mechanical skin. In this paper, practical acidizing in a typical carbonate oil reservoir located in the southwest of Iran is practiced, which shows an unexpected improvement after acidizing. To understand the acidizing effect on reservoir rock, the formation rock is analyzed on different scales. An acidizing laboratory te...

Existing fractured gas reservoir development techniques are mainly based on dual medium numerical-simulation models, which can, to a certain extent, effectively simulate natural fractures with high fracture density; however, these models have some limitations, particularly in terms of simulating the morphology and distribution. Considering carbonate reservoirs complex fractures, this paper, we ...

During production from oil wells, the deposition of asphaltene and wax at surface facilities porous media is one major operational challenges. The crude rate significantly reduced due to inside reservoir. In addition, these solids costly companies. this study, efficiency different solvents in dissolving was investigated through static dynamic tests. analysis solid deposits choke Iranian carbona...

Abstract The first phase of any hydraulic fracturing (HF) operation is to select carefully the best layers and wells based on a specific set criteria. Selecting HF candidates plays pivotal role in achieving desired objective such that attempt execute this treatment fails without performing comprehensive studies regard. In paper, data from 3 fractured carbonate reservoir one biggest oilfields Ir...

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...
