... in the loss of lives and equipment and adverse environmental effects. Thus, the safe and efficient separation of gases from gas-cut drilling fluids in the MGS is vital. The design and operational efficiency of the MGS depend on certain key elements in its sizing, such as the vent line length and diameter...

... measurements for a single tubular is in the range of 400,000 points for a typical 43-foot length of casing. The wall thickness inspection of tubulars can measure variations within ±0.004 of an inch. Introduction Diameter Measurements System Overview The diameter measurement element of the system...

... the buoyancy force. When applied to a portion of a pipe, buoyancy does not have contributions at the end caps of that portion of the drill-stem since these end caps are not in contact with the fluid, except at positions with a change of diameter. Therefore, one shall be cautious when calculating the local...

..." diameter. This drill string would require V-150 landing string, with a 6 5/8" FH tool joint diameter of 8.875". Hard banding would bring the tool joint nominal OD above 9". The depth of the well and planned string RPM presented risk of casing wear, therefore drillpipe protectors would also be required...

... With recent updates on Dutch mining regulations and standards in March 2019 ( Janssen and van der Sijp 2020 ), the well abandonment acceptance criteria became more stringent. Abandonment of more complex wellbores with large-diameter production casing, high shut-in wellhead pressure, complex well...

... The assumption behind the combined loading equivalent grade presented in API TR 5C3 Eq. (42) is that maximum stress occurs on the inner diameter. Indeed, that is the case in the absence of torsion and bending. However, accounting for torsion and bending in addition to those stresses requires...
