Received: August 22, 2016 Revised: February 07, 2017 Accepted: March 10, 2017 Abstract: Background: Tight sandstone reservoirs play an important role in the oil industry. The permeability of tight sandstone reservoir generally has stronger stress sensitivity than that of conventional reservoir because of the latter’s poor physical properties. However, the production analysis of tight sandstone ...

obtaining samples that represent original fluid of reservoirs optimizes reservoirs management. the optimized management increases recovery. also, selecting and performing proper improved oil recovery (ior) or enhance oil recovery (eor) programs depend on collecting representative samples. achieving accurate compositions of original in-situ fluid prevents overdesigning surface facilities. repres...

Lowto ultralow-permeability formations require “special” treatments/stimulation to make them produce economical quantities of hydrocarbon, and at the moment, multistage hydraulic fracturing (MSHF) is the most commonly used stimulation method for enhancing the exploitation of these reservoirs. Recently, the slotdrill (SD) completion technique was proposed as an alternative treatment method in su...

It is challenging to get water-based fracture fluid flow back into low-pressure gas reservoirs. In order solve the problem, supercritical CO 2 a novel type of non-aqueous fracturing technique with wide range applications prospect in tight sandstone. determine whether sandstone feasible cores from Jinqiu Gas field Sichuan Basin were used evaluate influence on formation sensitivity Supercritical ...

Compared with oil, natural gas has been the focus of energy industry in recent years. Renewable is goal and trend future developments, it made considerable progress; however, not reached ideal popularization rate. Therefore, still very important so far. In this paper, influence thermal injection room temperature on reservoir recovery analyzed, method water plugging by hot tight put forward. Ind...

Barmer Basin is one of the most prolific hydrocarbon basins of India having more than 30 discoveries to date. The Raageshwari Deep Gas (RDG) Field, situated in the southern Barmer Basin, was discovered in 2003 by exploration well Raageshwari-1 and is a part of RJ-ON-90/1 contract area operated by Cairn India. This field is characterized by tight gas-condensate reservoirs with excellent gas qual...
