High pressure and high temperature (HPHT) conditions in geothermal wells have necessitated the need to develop thermally stable drilling mud systems combat potential complications. This is because fluids degrade under HPHT due effects. study therefore aims establish optimum concentration of a cationic surfactant that would successfully modify surface silica nanoparticles thereafter, evaluate pe...

During drilling, almost 70% of wellbore instability issues result from the encountering shale formations. Various additives such as salts, silicates, and polymers are used in water-based mud to enhance its shale-inhibition capability; however, have certain limitations. Lately, ionic liquids deep eutectic solvents (DES) been by various research groups inhibitors drilling fluid due their biodegra...

Nanoparticles (NPs) as a nanotechnologies unit have huge potential for improving drilling fluids. However, the role of NPs in this field is still its infancy and consequently has attracted much more attention last years. This review going to investigate fluids modified by nanoparticles. Moreover, effects various nanoparticles include polymeric, ceramic, metal carbon-based on fluid technical eco...

Mud volcanoes, ranging in size between 50cm and 800m high, are found both on land and in submarine environments. Their variation in height and shape reflects the driving forces building them and the physical properties of their materials. The driving force behind the construction of mud volcanoes is overpressure of fluidised mud at depth within the sediment column. Although some component of ov...

In this paper an optical system for measuring the amount of dust deposition on commercial bag filters is presented. Dust laden gas is blown onto the filter, the dust remains on the surface and forms a compact layer called filter cake. For academic simulations as well as practical filter design it is desirable to know the thickness of this cake over the filter surface during operation, when the ...

This study designed the effective fluid loss agents for controlling loss. Various polymers have been used as additives using natural polymer from cassava starch. Bulky Cassava was cleaned with water and it grounded, filtered, dried, sieved to obtain suitable starch additive size. filtration mud cake test carried out under Low Pressure Temperature (LPLT) apparatus. The sample separated accommoda...

In petroleum production, Produced Water Re-Injection (PWRI) has earned much interest among disposal methods of the produced water. However, presence of the contaminants in the produced waters usually results in formation damage in well bores and their surrounding fracture systems. In the present study, modeling of external cake formation on a fracture in unsteady-state conditions i...
