Extrication of CBM Wellbore Fire Explosion Paradox in Enugu, South Eastern, Nigeria.

Methane dexterity and degasification in heavily stratified subsurface water aquifers sandwiched with coal seams surreptitiously expedited the recent fire explosion in Enugu State, South Eastern Nigeria. The verisimilitude is to divulge the non-availability of coal bed methane (CBM) reservoir engineering modeling technology. The aim of this study is to demonstrate the didactic, luminous and effective volubility of CBM reservoir engineering modeling techniques for extrication of the wellbore fire explosion paradox in Enugu state, Nigeria. The Schlumberger Eclipse simulated reservoir has a dimension of 8 ×8×2 with dual porosity of 0.05 and 0.15 located at depths of 1,000ft, 1,200ft and 1,400ft. Results inconceivably showed improvement in coal quality by 72.83% in the y direction indicating increased methane palpitation upsurge in that direction. Results of initial 40% CO2 isotherm fracture gas gave a cumulative maximum field gas pressure (FPR) of 540psi for the 1,400ft model. This indicates higher gas volatility with shallow depths. It is admonished to critically evaluate aquifers in zones deeper than 700ft to forestall future petrifying devastating occurrences triggered by maladroitness. [ABSTRACT FROM AUTHOR]
