Enhancing Characteristics of Well Cement Slurry Using Cellulose Based Polymers

Abstract

A forceful cement sheath is obligatory to certify long term integrity of the well. At high pressure and high temperature (HPHT) well, to successful completion of the cementing occupation has been more complex as the drilling is being Passed out in the highly deviated. To improvement preferred compressive strength and rheological properties has developed complex and hard in HPHT wells. The usage of cellulose-based polymers in the oil and gas well cementing, and the other submissions is being to investigated.The enlarged demand for the oil and gas has led to exploration of petroleum reserves into the high pressure and high temperature (HPHT) zones in extensive formations.At the drilling zones (HPHT) need to unusual design of cement slurry. Some of forms polymers and additives are being to investigated an used with the G-Class cement in the (HPHT) wells to Provide the exciting environment.The technique for the cement hydrocarbon production wells. In the high Temperature and high Pressure (HPHT) conditions, using the Polymers, cement, and additive composition. The cement-polymers composition has optionally admixed, comprises water and polymers with at least one additive selected to retarder, agent fluid loss, friction reducing agent, agent expanding, weighting agents and agent's density reducing, and yield point, in mandate to improve pump-ability and proper settling of cement slurry in (HPHT) wells.
