To meet future global oil and gas demands, unconventional gas resources will play an important role in the U.S and world energy supply. To develop unconventional gas resources, we must first identify their occurrences and quantify their potential. The analog methodology that provides supplementary analysis to characterize the less accessible reservoirs has been employed in the oil & gas industr...

Emission of methane (CH4), a potent greenhouse gas, from tropical reservoirs is of interest because such reservoirs experience conducive conditions for CH4 production through anaerobic microbial activities. It has been suggested that Indian reservoirs have the potential to emit as much as 33.5 MT of CH4 per annum to the atmosphere. However, this estimate is based on assumptions rather than actu...

many large oil and gas fields in the most productive world regions happen to be fractured. the exploration and development of these reservoirs is a true challenge for many operators. these difficulties are due to uncertainties in geological fracture properties such as aperture, length, connectivity and intensity distribution. to successfully address these challenges, it is paramount to improve ...

Hydrocarbon plumbing systems have been extensively documented in the past two decades using high-resolution 3D seismic data, exploiting ability of imaging techniques to reveal subsurface geometry gas charged sediments. In this paper, we present a detailed study hydrocarbon system from South China Sea, that involves both vertical and lateral (stratal) migration Miocene Recent clastic sediments c...

Detailed description of the heterogeneity of oil/gas reservoirs is needed to make performance predictions of oil/gas recovery. However, only limited measurements at a few locations are usually available. This combination of significant spatial heterogeneity with incomplete information about it leads to uncertainty about the values of reservoir properties and thus, to uncertainty in estimates of...

The most significant geo-energy sources in the world today continue to be oil, gas, and geothermal reservoirs. To increase oil gas reserves production, new theories are constantly being developed laboratory technologies applied oilfield. This Special Issue compiles recent research focusing on cutting-edge ideas technology reservoirs, covering fields of well drilling, cementing, hydraulic fractu...
