Proper Cementing to Reduce Time and Cost

Master Thesis in Petroleum engineeringThis work brings up some important aspects of cementing procedure with the aim of reducing WOC time, avoiding remedial cementing and referring to some new technologies regarding plug and abandonment. In the beginning, a general overview of cement composition and behavior is given to give the reader an understanding of some important aspects of cement which will lead to better understanding of the challenges and solutions. Different sources have been studied to give a general overview of cement and cementing procedures and to point out the correct steps and the potential failures in order to perform the cementing job in the best way possible and thus avoid any remedial job which is time-consuming, and time equals cost. In addition, this thesis highlights some researches that confirm the possibility of reducing the wait on cement time which is followed by the oil companies nowadays, as well as referring to new technologies which saves time worth millions of dollars during well plug and abandonment
