Impact of Uncertainties in Formation Thickness on Parameters Estimated from Well Testing Part 1: Gas Reservoirs
نویسندگان
چکیده
Well testing is of great importance in petroleum engineering, to have a kind of firsthand knowledge and estimating formation permeability, wellbore damage/ skin, etc. These parameters are further required to estimate production rate from a well and at the same time gives an idea of its productivity. These reservoir related parameters calculation is strongly dependent on formation thickness. Any uncertainty in formation thickness leads to ambiguous results, which in turn influences further reservoir development studies. This study focuses on analyzing the impact of such uncertainties and highlighting their effect on the resulting estimations, while considering cases of gas, oil and multiphase flow reservoirs one by one. The obtained results in case of gas reservoir shows that uncertainty in formation thickness has strong influence on well test estimated data. [Zahoor M. K., Khan A.

Net pay thickness is defined as that portion of a reservoir which contains economically producible hydrocarbons with today’s technology, prices, and costs. This thickness is a key parameter of the volumetric calculation of in-place hydrocarbons, well test interpretation, and reservoir characterization. A reservoir interval is considered as net pay when it contains hydrocarbons that can flow at ...
