Well Control Procedures for Dual Gradient Drilling as Compared to Conventional Riser Drilling
Proceedings of SPE/IADC Drilling Conference, 2003Abstract In order to meet the world's increasing demand for energy, petroleum producing companies must search for oil and gas in increasingly hostile environments. One area that shows great promise is in the deep water areas of the U.S. Gulf of Mexico.

Application of a Deepwater Riser Risk Analysis to Drilling Operations and Riser Design
Offshore Technology Conference, 2001Abstract Running and retrieving a deepwater marine drilling riser system is a high-risk operation that is conducted on a normal basis. During this operation the contractor is exposed to one of deepwater drilling's key problems, large cyclic top tension on the riser resulting from vessel motions. The extreme increase

Design of Floating Vessel Drilling Riser
Journal of Petroleum Technology, 1966FISCHER, WILLIAM, STANDARD OIL CO. OF CALIFORNIA, LA HABRA, CALIF. LUDWIG, MILTON, SAN FRANCISCO, CALIF. Abstract An offshore drilling riser, necessary to return drilling fluid to the drilling vessel and to guide the rotating drill pipe, will fail in water depths greater than 200 to 300 ft if it is ...

Thunder Horse Drilling Riser Break - The Road to Recovery
Proceedings of SPE Annual Technical Conference and Exhibition, 2004Abstract This article presents key learnings by BP's Wells Team on the Thunder Horse project after responding to a major incident— the break of the drilling riser on the Discoverer Enterprise drillship in May 2003 in the Gulf of Mexico.

Increasing the Operation Window for Drilling Risers on DP Vessels by Monitoring Riser Angles
Volume 3: Pipeline and Riser Technology, 2012Drilling operations are taking place in ever deeper waters and harsher environments using dynamically positioned (DP) vessels. A DP control system maintains the vessel in a fixed position or pre-determined track exclusively by means of active thrusters based on measured position from satellites and hydroacoustics.

Outline of scientific ocean drilling and specifications of riser drilling vessel Chikyu
Journal of Marine Science and Technology, 2003The Japan Marine Science and Technology Center (JAMSTEC) has been, and is now promoting the “OD21” program (i.e., “Ocean drilling in the 21st century”). This is the first plan in the world to utilize deep-water riser-drilling technologies for scientific drilling.

Mars TLP Drilling and Production Riser Systems
Offshore Technology Conference, 1997Abstract The Mars riser systems are a major departure from those previously used on TLPs. All risers are operated with top tensions only 20% above their wet weight; the high-pressure, light-weight drilling riser has a secondary pressure barrier while drilling the majority of the well; a platform-style rig is used ...

Vortex-Induced Vibration Effects of Production Risers in Proximity with Drilling Risers or Tendons
Offshore Technology Conference, 2018Abstract This paper examines the effects of ocean currents on the vortex-induced vibration response of deepwater tubulars, such as umbilicals, production risers, tendons, and drilling risers, in proximity. This issue has received very little attention by the industry yet potentially has substantial importance to the design of deepwater ...

Problems Affecting the Design of Drilling Risers
Proceedings of SPE European Spring Meeting, 1975American Institute of Mining, Metallurgical, and Petroleum Engineers, Inc. Abstract With increasing water depth many of the factors considered in making decisions related to the overall arrangement and operation of floating drilling equipment change significantly in magnitude and, consequently, in ...
