Title: A laboratory analysis of cement permeability of typical cement mixtures used in the Permian Basin
Author: Deshmukh, Viraj
Abstract: In the Petroleum Industry today , downhole cement plays an important role during drilling & production operations . It is responsible for lending strength to the casing for future production , it helps in preventing collapse of the formation , as well as restricts fluid movement between permeable zones . This downhole cement however , has different problems in the field from inadequate compressive strength , early setting of slurry etc . But of all these problems , sulfate attack on downhole cement is probably the biggest one facing the industry today . Another problem in use of different cement slurries has been the traditional lack of research for cement permeability , which has the biggest influence on the degree of this sulfate attack . Thus Texas Tech University & BJ Services have thus carried out a new study in my thesis , where we have studied & analyzed how sulfates in water react with the dry cement initially by measuring this initial permeability . Thus a study has also been carried out in measuring cement permeability of typical cement slurries used in the Permian Basin , something not yet documented & recorded officially before . This will give us a better understanding of cement properties for future reference .
