Squeeze Cement Volume Estimation (Case Study Hamra Field – Sudan)

Abstract

The volume of squeeze cementing process is a key factor for well intervention cost. In Sudanese oilfield, the estimation of squeeze volume has many limitations; this study is trying to estimate the optimum volume squeeze cement that depends on many operational factors. In this study the squeeze volume has been divided into many portions, the most important part is to predict the squeezed volume inside the formations; this point had been achieved via statistical analysis method using Mini-Tab (statics software), the model that has been built can predict the value of squeezed volume with a R2 value equal to 0.78 this value present the importance of the variable that did not taken in the model. The study procedure found that, if the study had been utilized about 40% of cement slurry would not be mixed, therefore 1346 meter of cement would not be drilled at all.
