Paper Number: SPE-189382-MS
... (H 2 S) exposure all work against nitrile and other common elastomers. H 2 S is a toxic gas that is present in many oil wells (especially in the Middle East regions) that can cause premature failure of elastomeric components. API 6A, Annex F outlines standards for immersion-based testing that can...

... of these motors has increased so has the capacity for motors to operate outside recommended limits. In a drilling motor, the component that typically fails the most is the elastomeric power section stator. Realizing the limitations of elastomers various tools, such as performance matching tools for motor...

Paper Number: SPE-97281-MS
... an elastomeric compound is bonded to the outside diameter of the pipe. When the pipe is expanded to contact the wellbore inside diameter, the elastomer is compressed between the formation and the solid pipe, providing a hydraulic seal. Unlike casedholes, drilled openholes are seldom gauge or guaranteed...

The correct amount of water as well as retarders is crucial for the best results during the dehydration process of the cement. By adding the correct type of elastomers, this pressure variation during the setting...
