Primary and Remedial Cementing
This skill module presents an overview of the planning and execution required to achieve the quality primary cementing of well casing strings to successfully isolate a wellbore’s geological column, including the well’s productive zone(s). Equipment and cement displacement practices are illustrated and described as well as methods to assess the resultant cement sheath surrounding casing following a cementing job. Preliminary lab work to formulate primary cement blends is described. And, various methods are presented in the remedial repair of poorly cemented zones which can lead to life of the well production problems. Several different cement squeeze techniques are explained, and recommended practices are described.
