Drilling cost optimization has always been an important issue in the petroleum industry. In order to save costs and create new markets for local materials, Ofo (D. micocarpum) and food gum (C. populnea) powders were evaluated in this study at high temperature as alternative to imported chemical additives in water based drilling fluid. The base mud composed of alkali beneficiated local clay, ach...
This study experimentally investigates the effect of multi-walled carbon nanotubes (MWNT’s), as a reinforcing material, on the physical properties of heavy-weight oil well cements. A candidate well is selected and the properties of the cement slurry used in a problematic section of the well are tested in the laboratory. Carbon nanotubes (CNT’s) are added as fibers to the cement slurry and the i...
