DRILLING FLUIDS DIFFERENTIAL STICKING TENDENCY DETERMINATION
Journal Title: UNKNOWN - Year 2005, Vol 17, Issue 1
Abstract
Differential sticking is def ned as stuck pipe caused by the differential pressure forces from an overbalanced mud column acting on the drillstring against f lter cake deposited on a permeable formation. It is infl uenced by drilling fl uid properties and characteristics of rock formations and has major impact on drilling eff ciency and well costs respectively. Differential sticking tendency of two drilling fl uids were determined in laboratory using sticking tester as well as infl uence of lubricant and increase of solids content on fl uid properties. Results of the testing are presented in the paper.
