Paper presented at the IADC/SPE Asia Pacific Drilling Technology Conference and Exhibition, August 27–29, 2018
Paper Number: SPE-190970-MS
... Figure 2 Centralization and average fluid concentration in annulus, 3D aperture result. Studies have shown that displacement efficiency (mud removal) can increase from 25 to 50% when there is no pipe movement to as much as 100 % with movement. Movement of the pipe will have several...

... been mitigated using high torque drill pipe and torque reduction tools. Reamer and back-reaming out of hole have been used to smoothen wellbore which facilitate wireline logging and casing running operation. Eccentric casing shoe and low-friction centralizers have been used to further aid running...

... centralizers should be used (and if so, specific spacing), whether fluids that will reduce the friction coefficients should be considered, and will also examine whether there is the possibility or a need of floating the liner assembly to depth. To summarize, the ultimate goal of the well designer is to use...

Paper Number: SPE-47804-MS
... Abstract Centralizers for highly inclined and horizontal wells have to fulfill several requirements. Their main task is to provide adequate standoff. Additionally, centralizers have to facilitate casing and liner running and should allow pipe rotation. While bow-type centralizers normally are...
