Title
Developing Conventional and Unconventional Oil and Gas Resources: Prospects and Opportunities
Abstract: Crude oil and natural gas form an integral part of energy resources. Their contribution to the energy basket is significant and is predicted to grow in the future. This demands exploring and developing unconventional hydrocarbon resources such as shale gas gas hydrate and heavy oil reservoirs in addition to enhancing the recovery from the conventional mature oil reservoirs. Gas hydrates have always inspired researchers for their role in flow assurance. However gas hydrates show potential not only as an abundant energy resource but also for developing new oil and gas technologies such as natural gas storage and transportation gas separation desalination and CO2 sequestration. Phase behavior models are necessary for predicting the hydrate phase stability conditions for successful engineering applications. New phase behavior models for the gas hydrate system in the presence of various inhibitors and promoters along with selected experimental studies will be presented. Experimental studies on the kinetics of hydrate formation and dissociation in porous media and saline environment relevant for gas recovery and CO2 sequestration will be discussed. Recent developments on the high-pressure rheology of the pure methane hydrate system will also be presented. Enhanced oil recovery (EOR) methods such as chemical thermal and microbial-EOR need further development for waxy and heavy crude oil reservoirs. Nanotechnology may offer solutions for next-generation oil and gas technologies. Nanoparticles have been explored to improve the thermal stability and high pressure rheological properties of Pickering oil/water emulsion. The thermally stable emulsions have been evaluated in the laboratory as an efficient flooding agent for an EOR method. Nanoparticles in the form of nanofluids in xanthan gum have also been found to improve the thermal stability high pressure rheological and fluid loss properties of the water based drilling fluids. In addition evaluation of ionic liquids for heavy crude oil dissolution and chemical-EOR method will be discussed. Selected results on the microbial degradation of long-chain hydrocarbons and waxy crude oil relevant for flow assurance and microbial-EOR will be presented.Biography: Dr. Jitendra Sangwai is currently working as an Associate Professor in the Petroleum Engineering Program Department of Ocean Engineering at Indian Institute of Technology (IITM) Madras Chennai India.
