Overview: Drilling operations cause changes in well-bore temperatures that can significantly impact effective fracture gradients. Some of these adverse thermal effects can be managed by adjusting parameters of the drilling process such as mud properties and hydraulics. As thermal management systems are adopted and used in the industry to minimize lost circulation risks and increase effective fracture gradients, especially in deepwater environments, several advancements in technology and operating practices may be realized. Among them are higher-pressure circulating systems, surface-heating systems, and thermal insulation for circulating systems and deepwater drilling risers.
