Depleted natural gas reservoirs are promising targets for carbon dioxide sequestration. Although depleted, these reservoirs are not devoid of methane, and carbon dioxide injection may allow enhanced production of methane by reservoir repressurization or pressure maintenance. Based on the favorable results of numerous simulation studies, we propose a field test of the Carbon Sequestration with E...

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. Re...

Abstract The planning and developmental decisions succeeding the discovery of an unconventional oil gas field is utmost importance in attaining successful exploitation production from these tight reservoirs. development hydrocarbon reservoirs require requires adequate execution which could be challenging, due to sequence heterogeneous lithologies formations. In this study, we designed presented...

With the continuous exploration and development of unconventional oil gas reservoirs, volume fracturing technology becomes one necessary measures for developing shale tight sandstone reservoirs effectively. Volume usually uses slickwater drag-reducing agent as core system. The composition system is main factor determining its performance. Polyacrylamide has many amide groups in chain, high acti...

Reservoir rocks of the Pearl River Mouth Basin’s Lufeng Sag have low porosity (average 12.6%) and permeability 16.5 mD), requiring hydraulic fracturing to obtain economic production oil gas. To contribute understanding these reservoirs, promote successful in region, we analyzed mechanical properties tight sandstone. Moreover, introduced shear/tensile strength factor, combination with fracture t...

Gas storage and flow behavior in the shale gas rocks are complex and hard to identify by conventional core analysis. This study integrates clustering analysis techniques from material science, petrophysics, and petrology to characterize North American shale gas samples from Utica, Haynesville, and Fayetteville shale gas plays. High pressure (up to 60,000 psi) mercury porosimetry analysis (MICP)...
