Abstract:
With depletion of conventional gas reservoirs around the world, paradigm has widely shifted for exploring unconventional gas. Though, unconventional gas production has been going on for quit some time in North America but is relatively new for rest of the world. In the opinion of geoscientists huge volumes of unconventional gas are still untapped. Finding & development of these reserves would play vital role in the stability of E&P business as well as economy of major nations. Various regions deal with their own classification of unconventional/tight reservoirs, however, generally accepted definition of tight reservoirs suggests, that sands having permeability of less than 0.1mD fall within tight sand. As Middle Indus Basin (MIB) is core operating area of OMV (Pakistan). Declining production from conventional gas pools demanded serious efforts for exploring new reserves. Pakistan a nation hungry in energy has a significant gas market. These factors triggered the initiation of comprehensive efforts to search for the unconventional gas. Therefore, OMV is putting substantial resources for understanding & development of unconventional reservoirs in MIB. Full fledged study through consultant is currently underway for exploitation of unconventional gas reservoirs. Consultant will perform detailed study on drilling of tight reservoirs, petrophysical evaluation, geological depositional models, reservoir & production engineering aspects of unconventional reservoirs. Based on the outcome of the study few, pilot wells will be drilled for testing & proving the proposed technology.
