Dual Gradient Drilling (DGD) for Enhancing Well Control
In modern deepwater and offshore drilling operations, managing wellbore pressure is one of the most critical challenges. Traditional single-gradient drilling systems often face limitations when encountering narrow pore pressure and fracture gradients, especially in ultra-deepwater wells. To overcome this challenge, Dual Gradient Drilling (DGD) is emerging as a revolutionary technology that significantly enhances well control and safety, while reducing overall drilling costs.
