... capability, spending many hours on back reaming to get the bottomhole assembly (BHA) out of the hole. The requirement for a reliable passive reaming device became necessary for less time-consuming trips. This paper discusses a review of a downhole technology that has helped improve metrics against this time...

... circulation might take place. CT conveyed production logging requires a CT plug to prevent production circulation across by-pass section while operating the ESP. The circulation is prevented by the seal assembly which exists in the CT plug and located on the coil tube. The Bottom Hole Assembly (BHA) consist...

The pilot hole is then enlarged to the required bigger-size borehole using a drill bit and, again, a downhole motor. The Bottom Hole Assemblies (BHAs) for both the pilot hole and the enlarged borehole, are designed...

...¼-in. curve section, and drilling through interbedded hard layers with severe downhole stick/slip and downhole vibrations. Historically, both motor and motorized rotary steerable system (MRSS) bottomhole assemblies (BHAs) were used to drill this section. However, the motor BHA's lower rate of penetration (ROP...

Accordingly, several Bottom Hole Assembly (BHA) designs were thoroughly examined to determine the appropriate CT deployment tool and carry out...

... is encountered in hard Dolomite/Limestone intervals. Conventional directional drilling bottom hole assemblies (BHA) are deployed in these wells. This interface severity is likely to initiate axial and lateral vibrations causing bit and BHA damages. The 12¼-in. bore hole section of a Utmaniyah well was planned...
