Efficient Removal of Magnetic Contamination From Drilling Fluids: The Effect on Directional Drilling
Abstract Magnetic debris in a drilling fluid have significant influence on the ability of to maintain its function. Down hole logging can suffer from poor signal noise ratios. Directional areas close magnetic North Pole, such as Barents Sea, Northern Canada, or Russia, because contamination fluid. particles introduce additional errors surveying compared those normally included ellipsoid uncerta...
The accurate control of the wellbore pressure not only prevents lost circulation/blowout and fracturing formation by managing the density of the drilling fluid, but also improves productivity by mitigating reservoir damage. Calculating the geothermal pressure of a geothermal well by constant parameters would easily bring big errors, as the changes of physical, rheological and thermal properties...
High-volume hydraulic fracturing (HVHF) has revolutionized the oil and gas industry worldwide but has been accompanied by highly controversial incidents of reported water contamination. For example, groundwater contamination by stray natural gas and spillage of brine and other gas drilling-related fluids is known to occur. However, contamination of shallow potable aquifers by HVHF at depth has ...
In oil and gas and geothermal installations, open channels followed by sieves for removal of drill cuttings, are used to monitor the quality and quantity of the drilling fluids. Drilling fluid flow rate is difficult to measure due to the varying flow conditions (e.g., wavy, turbulent and irregular) and the presence of drilling cuttings and gas bubbles. Inclusion of a Venturi section in the open...
