...Jamil Abdo; Muhammad Danish Haneef Achieving stability of drilling fluids (DFs) rheology with high temperature and high pressure (HTHP) has always seen a growing focus with increasing pursuits of deep drilling operations to maximize hydrocarbon recovery. Since there is no boundary of how deep...

... of both water and oil-based drilling fluids. In this study, hydrophobic iron oxide NPs were synthesized by thermal decomposition of iron pentacarbonyl in an inert atmosphere, and its performance was tested in the oil-based drilling fluid with 90/10 oil-to-water ratio (base fluid). Oil-based drilling...

...Mobeen Murtaza; Zeeshan Tariq; Mohamed Mahmoud; Muhammad Shahzad Kamal; Dhafer Al-Shehri Different additives such as barite, calcium carbonate, hematite, and ilmenite having high-density and fine solid materials are used to increase the density of drilling fluids. However, some of the weighting...

...Per A. Amundsen; Torgeir Torkildsen; Arild Saasen Magnetic materials in the drilling fluid used for drilling a petroleum well can significantly shield the Earth’s magnetic field as measured by magnetic sensors inside the drilling pipe. This has been shown to sometimes cause significant errors...

... alcohol propoxylate sulfate remained in the bath after washing, which minimizes the need for make-up surfactant when the wash water is reused. 15 04 2003 15 06 2004 There are different types of drilling fluids; as light as foam-containing drilling fluids, with moderate to light...
