Abstract
  Challenges on rock absolute permeability prediction from tiny sample when laboratory apparatus is not applicable and without pore network modelling is remarkable. This prediction using the characterization of micro-computed tomography images have been studied in this paper. Twenty series of 2D micro ...  Read More

Abstract
  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. ...  Read More

3. Impact of H2S Content and Excess Air on Pollutant Emission in Sour Gas Flares

Ahmed Zoeir; Alireza Tabatabaei Nejad; Elnaz Khodapanah

Volume 8, Issue 1 , Winter 2019, , Pages 1-10

http://dx.doi.org/10.22050/ijogst.2018.127937.1450

Abstract
  In sour gas flares,  content like any other components in inlet gas influences adiabatic flame temperature, which, in turn, impacts on the pollutant emission. Wherever flame temperature increases, the endothermic reaction between  and  is accelerated, which means higher  emission ...  Read More
