Paper Number: SPE-214914-MS
... Abstract Brunei Shell Petroleum (BSP) constructs many wells that require active sand control for multiple zones in cased hole environment with the option for zonal selectivity and allowing watered out zones to be isolated through well intervention. The most frequently used tubing in these wells...

Pump-down diagnostic testing is another technique for assessing near wellbore conditions and treatment isolation characteristics. It is more limited in scope than some of the previously discussed methods but requires no additional...

... Abstract Currently, hydraulic isolation of wells drilled with nonaqueous fluids (NAFs) relies heavily on the elimination of mud from the annuli before the placement of cement. Failure to expel all NAFs will result in residual fluid channels that will compromise well integrity and can even serve...

Every cementing operation has a set of specific objectives combining technical consideration (ranging from simple fill-up criteria to sophisticated isolation requirements) with project economics and local regulations. To fulfill its objectives, the cementing design must first consider wellbore...
