Abstract One of the most significant problems in oil and gas sector is swelling shale when it comes contact with water. The migration hydrogen ions (H + ) from water-based drilling fluid into platelets formation causes to swell, which eventually increases size sample makes structure weak. This results wellbore instability problem that ultimately reduces integrity a wellbore. In this study, was ...

Abstract Reservoir protection in well drilling and completion is one of the most significant challenges that have been connected with quality temporary plugging zone recovery value reservoir permeability when foreign water invaded into copied agents. The regular agents are linked high demand for matching rate about pore throat formation, effect a single, poor environmental performance, etc. whi...

As part of the government response to the Deepwater Horizon blowout, a Well Integrity Team evaluated the geologic hazards of shutting in the Macondo Well at the seafloor and determined the conditions under which it could safely be undertaken. Of particular concern was the possibility that, under the anticipated high shut-in pressures, oil could leak out of the well casing below the seafloor. Su...

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 mathematical models and artificial intelligence have been proposed to predict the rate o...

Abstract The overbalance pressure drilling technique is well common and practiced during the operations in petroleum field. This parameter very critical affects drilled formation characteristics, therefore, main objective of current study to evaluate impact that applied operation on rock elastic strength characteristics by employing integrated lab experimental work. Berea Buff sandstone type wa...

A theory is presented for the mass transport induced by a small-amplitude progressive wave propagating in water over a thin layer of viscoelastic mud modelled as a Voigt medium. Based on a sharp contrast in length scales near the bed, the boundary-layer approximation is applied to the Navier–Stokes equations in Lagrangian form, which are then solved for the first-order oscillatory motions in th...
