DRILLING FLUIDS DIFFERENTIAL STICKING TENDENCY DETERMINATION
Differential sticking is defined as stuck pipe caused by the differential pressure forces from an overbalanced mud column acting on the drillstring against filter cake deposited on a permeable formation. It is influenced by drilling fluid properties and characteristics of rock formations and has major impact on drilling efficiency and well costs respectively. Differential sticking tendency of two drilling fluids were determined in laboratory using sticking tester as well as influence of lubricant and increase of solids content on fluid properties. Results of the testing are presented in the paper.
