Continuous Circulation Systems (CCS) have been around since the JIP between Shell, BP, Statoil, BG, Total and Eni in October 2000. Initial reports of these systems demonstrated that while cumbersome, the use of CCS is of benefit to drilling ERD wells. Continuous circulation keeps cuttings moving out of the wellbore, reducing or eliminating the time required to circulate clean any high-angle section before making a drill pipe connection or before tripping out of the hole.

Continuous Circulation Systems (CCS) have been around since the JIP between Shell, BP, Statoil, BG, Total and Eni in October 2000. Initial reports of these systems demonstrated that while cumbersome, the use of CCS is of benefit to drilling ERD wells. Continuous circulation keeps cuttings moving out of the wellbore, reducing or eliminating the time required to circulate clean any high-angle section before making a drill pipe connection or before tripping out of the hole.
Continuous Circulation over each connection enhances the management of Equivalent Circulating Density(ECD) to control the bottom hole pressure on the well by never switching off the pumps, therefore the wellbore never experiences an Equivalent Static Density(ESD). Through this mechanism, the application of CCS has also been proven to manage bottom hole pressure constantly, which in conjunction with good drilling practices for torque and drag management, are key factors in drilling any Extended Reach Drilling(ERD), Complex or High Pressure/High Temperature (HPHT) well.

SPE-204046 - Presented at the SPE/IADC Drilling Conference Virtual 8-12 March 2021
Continuous Circulation Systems (CCS) have been used in the past to help drill wells where interactions between the mud weight and the formation may increase risks, thereby allowing the well to be drilled without encountering drilling problems or damaging the formation, whilst reaching total depth in the planned time. Previous systems have, however, relied on people working in the red zone. This paper… Show more

SPE-204046 - Presented at the SPE/IADC Drilling Conference Virtual 8-12 March 2021
Continuous Circulation Systems (CCS) have been used in the past to help drill wells where interactions between the mud weight and the formation may increase risks, thereby allowing the well to be drilled without encountering drilling problems or damaging the formation, whilst reaching total depth in the planned time. Previous systems have, however, relied on people working in the red zone. This paper discusses the process of making drill pipe connections, with continuous circulation, utilising a fully automatic deployment system to add value by removing the risk of people around the drill pipe during the connection, working in conjunction with other automated rig systems to deliver the advantages of continuously circulation over each connection.

This paper describes experiences, challenges, and approaches to solving the problems related to creating an advanced early kick detection system suitable for floating mobile offshore drilling units. Necessary components, operational considerations, and design limitations will be discussed. Additionally, a discussion will offered on the current state of regulatory requirements related to kick detection and considerations for future standards.

Casing Drilling is a process in which a well is drilled and cased simultaneously. This innovative technology has been successfully practiced for the past decade. The original purpose of developing Casing Drilling was to eliminate Non Productive Time (NPT) associated with tripping drill pipe and running casing. However, during early implementation of the technology, other benefits were observed while drilling with large diameter casing. This paper reviews four of these advantages which are lost… Show more

Casing Drilling is a process in which a well is drilled and cased simultaneously. This innovative technology has been successfully practiced for the past decade. The original purpose of developing Casing Drilling was to eliminate Non Productive Time (NPT) associated with tripping drill pipe and running casing. However, during early implementation of the technology, other benefits were observed while drilling with large diameter casing. This paper reviews four of these advantages which are lost circulation reduction, wellbore strengthening, improved wellbore stability, and drilling-induced formation damage mitigation Show less
