Abstract
  Column final test facing new challenge, in addition to casing burst/collapse limitations; buckling occurrence creates serious problems. Practically, in case of slight gap between mud and slurry densities, buckling initiation is inevitable. Casing elongation, bending and buckling detailed, to define column ...  Read More

An Experimental Investigation on the Effect of SiO2, CuO, and ZnO Nanoparticles on Filtration Properties of Drilling Fluid as a Function of Pressure and Temperature

Borzu Asgari pirbalouti

Volume 11, Issue 1 , January 2022

http://dx.doi.org/10.22050/ijogst.2022.322972.1619

Abstract
  Among the different operating parameters that must be carefully controlled during the drilling operation, the penetration of drilling mud into a permeable zone of formations is an essential parameter that can introduce a destructive effect on the productive zone. Concerning this, the current investigation ...  Read More

Aref Khazaei; Reza Radfar; Abbas Toloie Eshlaghy

Volume 10, Issue 3 , July 2021, , Pages 83-98

http://dx.doi.org/10.22050/ijogst.2021.138844

Abstract
  Iran is one of the largest oil and gas producers in the world. Intelligent manufacturing approaches can lead to better performance and lower costs of the well drilling process. One of the most critical issues during the drilling operation is the wellbore stability. Instability of wellbore can occur at ...  Read More

Effectiveness of Alumina Nanoparticles in Improving the Rheological Properties of Water-Based Drilling Mud

Afshar Alihosseini; Ali Hassan Zadeh; Majid Monajjemi; Mahdi Nazary Sarem

Volume 10, Issue 2 , April 2021, , Pages 12-27

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

Abstract
  Wellbore stability is one of the challenges in the drilling industry. Shale formation is one of the most problematic rocks during drilling because the rock has very low permeability and tiny pores (nanometers). This study assesses the viability of the alumina nanoparticles (Al2O3) in water-based mud. ...  Read More

Application of an Adaptive Neuro-fuzzy Inference System and Mathematical Rate of Penetration Models to Predicting Drilling Rate

Hossein Yavari; Mohammad Sabah; Rassoul Khosravanian; David. A Wood

Volume 7, Issue 3 , July 2018, , Pages 73-100

http://dx.doi.org/10.22050/ijogst.2018.83374.1391

Abstract
  The rate of penetration (ROP) is one of the vital parameters which directly affects the drilling time and costs. There are various parameters that influence the drilling rate; they include weight on bit, rotational speed, mud weight, bit type, formation type, and bit hydraulic. Several approaches, including ...  Read More
