RHEOLOGY OF AQUEOUS AND POLYMER-BASED NITROGEN FOAMS AT HIGH PRESSURE AND HIGH TEMPERATURE (HPHT) CONDITIONS
Firoze Akhtar, Tarek (2017-05-12)Foams are complex mixtures of gas and liquid held together by a surfactant at the gas-water interface. The use of foams find application in many industrial operations such as underbalanced drilling fluid, fracturing fluid ... -
Stability of aqueous foams at high pressure and the impact of contaminants
Obisesan, Oyindamola (2021-12-18)Foam is a mixture of gas bubbles dispersed in a continuous liquid phase that exhibits some form of structure. Foam is used in various oil and gas industry operations such as drilling, cementing, and fracking. The properties ... -
Stabilization of drilling foams using nanoparticles
Salih, Mohamed (2023-05)Underbalanced drilling often uses foam because of its superior hole-cleaning capacity, low density, and reduced liquid requirements. However, it must be stable under borehole conditions to function as a drilling fluid. ... -
Study on the mechanical and thermal properties of class G cement composites
Romero Tellez, Miguel Leonardo (2023-12-15)Nowadays the consumption of hydrocarbons such as oil and gas are higher than ever before, for that reason, the world is constantly looking for the development of new oil formations that were not accessible before due to ... -
Studying “fitness for service” of the sealing assemblies and cement system
Kwatia, George Ohene (2018-05)Well integrity is a crucial phase of well design and construction, as such multiple barriers are usually installed in wells to prevent any migration of formation fluids. One of these barriers include the elastomeric sealing ... -
SULFIDE STRESS CRACKING BEHAVIOR OF GRADE C-110, Q-125 AND T-95 STEEL TUBULARS UNDER HIGH-PRESSURE CONDITIONS
Jeon, Jiwon (2016-12-16)Due to the expansion of hydrocarbon exploration into challenging sour oil and gas resources, the industry is now facing severe sour related corrosion problem. Sulfide Stress Cracking (SSC) is one of the detrimental types ... -
Synergistic interactions of xanthan and guar gum polymers
Govindu, Abhishek (2015)Polymers such as xanthan and guar gum are widely used in the oilfield and food industry as viscosifiers. In hydraulic fracturing operation, guar gum polymer solution is used as fracturing fluid to create fracture in a ...
