Volume 10, Issue 2 , Spring 2021

http://dx.doi.org/10.22050/ijogst.2021.269283.1581

Abstract
  Wellbore stability is of one of challenges in drilling industry. Shale formation is of one of the most problematic rocks during drilling because the rock has very low permeability and very small pores (nanometers). In this study, the viability of the Alumina nanoparticles in Water-Based Mud (WBM) is ...  Read More

Volume 10, Issue 2 , Spring 2021

http://dx.doi.org/10.22050/ijogst.2021.278551.1588

Abstract
  This paper investigates the role of the effective thickness of the Asmari reservoir formation zones on oil production in one of the Iranian carbonate oil fields. Effective thickness is a term that includes the total gross thickness of rocks by lithofacies for a selected wellbore. The lithology of the ...  Read More
