Evaluation of Closely Spaced Infill Wells in Unconventional Mature Coalbed Methane Field: A Simulation Approach.

This study presents the work carried out to evaluate the effectiveness of closely spaced infill wells in enhancing recovery from a mature coal bed methane (CBM) field. The primary objective was to assess the potential for increasing gas production rates, accelerating reserve monetization, and improving the overall recovery efficiency in an unconventional reservoir setting. The authors utilized an integrated approach combining core-hole data, geological and geophysical models, historical production performance, and a history-matched dynamic reservoir model to support technical decisions.

A Critical Review on Parameters Affecting the Feasibility of Underground Hydrogen Storage.

The need and demand for energy are ever increasing with the rapid urbanization of the global population. Near-future economic development and consequent expected industrialization are the strongest indicators of the rising energy requirement. Though fossil fuel and coal are catering toward a major chunk of energy demand, their negative or adverse impact in terms of emission of greenhouse gases (GHGs) and carbon dioxide (CO) is causing global warming and imbalance in environmental conditions, leading to a search for commercially viable alternate energy types.
