A 7in. production casing liner is planned for an 8l/2in. hole. Assume that a /gal lignosulfonate mud will be used. Determine the critical velocity using the Bingham model (see Chapter 18) and compute the minimum acceptable flow rate in the annulus to achieve turbulence. In addition, determine the minimum acceptable flow rale if the hole is eroded to in.

Upon completion of the well, a cementing report shall be filed with the Commission on the prescribed form. (iv) Before parallel (nonconcentric) strings of pipe are cemented in a well, surface or intermediate casing must be set and cemented through the protection depth. (I) Mechanical integrity test of surface casing after drillout.

During drilling, completions and production operations, all groundwaterbearing rock formations are protected from the contents of the well by layers of steel pipe (casing) and cement sheaths. The process of wellbore construction is highly regulated, including the depth to which casing must be set and the quality of cement used.

Chapter 3: Cementing Cementing is one of the most critical steps in well completion. Sadly, coming at the end of drilling and in the haste to put a well on production, rarely is the time and commitment taken to get a good job. We then spend significantly more time correcting it or battling the effects of a bad cement job.
