Coal bed methane (CBM) is a greenhouse gas trapped in underground coal seams and extracted for various domestic, commercial and industrial usages - especially gas-fired electric generation. CBM is considered to be the most potential source of clean energy, and the recovery process requires drilling boreholes into a coal deposit and dewatering (pumping out the ground water), so that the gas is released from the coal matrix and diffuses through the coal bed's cleats and fractures towards the well bore. Shallow wells are drilled (less than 1,500 mt) to test coal seams, while attaining a higher recoverability rate is now possible due to technology evolution. High permeability, thick seams and high gas content are some of the crucial factors which are taken into account to evaluate the commercial viability of CBM projects. Retrieving trapped methane also helps minimise mining hazards and environmental impact.
CBM Services Portfolio
To meet the rapidly growing energy demands, industry leaders now focus on the exploration, extraction and commercial utilisation of coal bed methane. Shiv-Vani, in collaboration with its global business partners, has ventured into this new area of the energy sector and offers a full range of consultation services for CBM prospecting and production. We are the only integrated CBM services provider in India and have already completed more than 100 CBM projects worldwide. The company has been awarded the prestigious ONGC project for exploration and development of coal bed methane (CBM) in the state of Jharkhand. We also publish various technical papers and articles on coalbed methane development.
From reservoir analysis, horizontal and directional drilling, well testing, fracture treatment designing and reservoir simulation through to production forecast, optimisation and economic evaluation - our comprehensive range of integrated CBM services will help you identify the methane potentials, locate the best CBM reservoirs and optimise the CBM production of new and existing wells. At Shiv-Vani, our multidisciplinary team leverages extensive geo-science and engineering experience to generate a comprehensive exploration & development model. We study a coal basin's geologic and hydrologic characteristics, as well as field area particulars - keeping in view existing performances and previous records of mining, drilling, completion and operations. Our experts then integrate the well performance data with regional findings to define productive areas and forecast the potentials of CBM reservoirs. We employ highly sophisticated and advanced simulators for best-possible production & recovery of methane from coal seam reservoirs, while our capabilities to engage in a whole range of crucial activities such as
horizontal and directional drilling help you ensure a significant increase in flow rates and optimised CBM production. We are the first upstream services provider to introduce in-seam directional drilling for the CBM segment in India.
