Abstract
Since Dual Gradient Drilling (DGD) is a new and advanced drilling technology, currently its methods, procedures, simulations and experiments are still underdeveloped. It requires more study, research and advanced methods on DGD systems. The motivation of the paper is to study DGD systems, design good operational drilling parameters, and work on automated DGD systems to further realize safe and efficient drilling. This paper aims to implement automated DGD systems by regulating the mud level in the riser to maintain the stable bottom hole pressure during connection operations. Furthermore, the sensitivity analysis of parameters is included and good configuration parameters are recommended.
