Dual Gradient Drilling in Energy Efficient and Safe Manner

A. Kartik, Abhay Sharma, and Arti Jain

Abstract— At present the deep sea drilling utilizes conventional drilling fluids and enormous number of casings which significantly affects the fluid density. The well productivity is directly affected by the inculcation/leakage of mud in low producing zones. The cost of deep sea water exploration rapidly increases and at the same time imposes technical boundaries on the depths of the well that can be reached thereby affecting the productivity. Dual Gradient Drilling (DGD) is the establishment of multiple pressure gradients within the selected sections of the annulus for managing the annular pressure profile. DGD is a particular type of managed pressure drilling. In this paper we discuss the process of DGD in detail using energy efficient methods and the various advantages which this technology has to offer keeping in mind the health, safety and environment. In a nutshell DGD is an area which implemented properly using appropriate methods can help in reaping maximum benefits of Off-Shore Drilling.

Index Terms— Bottom hole pressure, managed pressure drilling, variable frequency drives, water effluent treatment.
