... Abstract Synthetic oil base drilling muds are re-cycled for cost efficiency and to minimize environmental effects. Invariably, very fine micro-sized magnetic or paramagnetic material from drill-string and casing wear accumulates in the drilling mud over time and cause significant shielding...

... Abstract In this study, the effects of magnetic field strength and temperatures on the electrical resistivity and rheological properties of a sensing smart bentonite drilling mud modified with iron oxide nanoparticles (nanoFe 2 O 3 ) were investigated. The bentonite contents in the smart...

... Abstract There is a need to accurately measure the density of drilling mud and well flow rate at downhole locations in the wellbore. Mud density can be determined by measuring the differential pressure between two locations in the well. The most common manner of measuring flow rate is also...

... conditions. Recent case studies on oil well failures have clearly identified cementing and drilling mud contamination as some of the issues that resulted in various types of delays in the cementing operations. For a successful cementing operation, it is critical to monitor the drilling and cementing...

... Abstract Drilling muds are used in oil, gas, and geothermal well drilling, and fluid loss and filter cake formation are critical issues related to successful operations. Also, the filter cake formation and fluid loss are affected by high pressure and high temperature (HPHT) in the borehole...

... is the extensive use of water-based drilling muds. Water density is not particularly sensitive to pressure and temperature, so surface measured mud weight doesn't usually vary much in conventional wells. Oil-based and synthetic oil-based muds, on the other hand, are much more pressure and temperature sensitive...

The ejection of mud will reduce the hydrostatic pressure and mechanical support to the wellbore, which may lead to hole enlargement, kick, uncontrolled gas release, blowouts and finally wellbore collapse...
