... Abstract Casing Running Tool (CRT) combines many functions of other tools, such as circulation heads, casing and tubing rotation, and connection makeup. The technology's initial design was for drilling with casing. However, it is currently used widely in running and makeup operations...

.... The section was drilled with 70 hours of on-bottom drilling and a total of 88.25 hours of tripping and circulation. A new benchmark was established for the reliability of float equipment and stage collar with constant rotation as reaching the total depth of a challenging drilling environment. Plastering...

... velocity was reported in the range of 3 to 4 ft/sec, depending on the value of various parameters, such as: Mud rheology Drilling rate Pipe eccentricity Rotational speed There were several findings: Under subcritical flow conditions, a medium-rheology mud (PV = 14 and YP = 14...

..., did not yield acceptable cement bond log results despite following oil and gas cementing industry best practices, including pipe rotation. This paper documents a comparison of six offset horizontal liners, focusing on the impact of the MSCS technology. The paper focuses on several 4-½-in. liners...

... different flow path mode on top of the isolation mode without any necessity to pull out of hole nor to disconnect the pipe at surface. Different from any other conventional tool, the command to change the flow path mode is fully achieved only by manipulating absolute pressure or pipe rotation speed. Thus...

.... To solve the issue an R&D initiative was launched to investigate different methods to enable a PDC shearing element to rotate while drilling to increase overall cutting efficiency and bit life. Engineers investigated different retention methods to create the optimal driving force and allow full cutter...

...-time hydraulic calculation method was established, in which the influence of drilling pipes rotation and annular eccentricity were taken into account. In order to improve the calculation precision, the flow channel both in pipe and annuli was divided into several sections, through which the different...

... conditions using a flow loop which includes a 12 meter long test section with a 2" OD freely rotating drillstring inside a 4" ID wellbore made of concrete. Solid particles were injected while circulating the drilling fluid through the test section at two inclinations; horizontal and 30° inclined from...

... and driveshaft are able to rotate independently of the drillstring in a stuck bit event. A conventional motor/turbine has no reliable mechanism to transfer the available high torque from the drillstring to the bit, leaving axial force (pushing/pulling) as the only means to free a stuck bit/BHA. For this reason...
