A research paper on the design of drilling and completion fluids for a North Sea oilfield found there was no direct connection between oil - based drilling - fluid - filtrate loss to the formation and formation conditions caused by the drilling fluid . Damage is more likely to be caused by the drilling - fluid filter cake sticking to the formation , according to the study by Corex , Aker BP and the university of Stavanger . It involves simulating the operational situation at reservoir conditions , gathering data to analyze data , in order to minimise operational risk .
A research paper on the design of drilling and completion fluids for a North Sea oilfield found there was no direct connection between oil-based drilling-fluid-filtrate loss to the formation and formation damage caused by the drilling fluid. Damage is more likely to be caused by the drilling-fluid filter cake sticking to the formation, according to the study by Corex, Aker BP and the University of Stavanger. It recommends simulating the operational sequence at reservoir conditions, gathering information to interpret data, in order to minimise operational risk.
