The Evolution of Deepwater Drilling in Brazil
Proceedings of SPE Latin America Petroleum Engineering Conference, 1990ABSTRACT In the beginning of the last decade PETROBRÁS identified, in the Campos Basin, some promising prospects under deepwater. At that time, deepwater drilling was a new activity and there were few drilling units capable of operating in great water depths. The daily rates were expensive and no deepwater drilling program

Deepwater Drilling: Driven by Culture?
The Way Ahead, 2013Soft Skills - To what extent is deepwater drilling driven by culture? Deepwater drilling is a high-risk operation. It involves going below water depths of 500 ft to explore for oil and gas. If there are any issues with the subsurface equipment, divers cannot intervene because human beings are physically incapable of tolerating such ...

Five Years Experience Deepwater Drilling
SPE Annual Fall Technical Conference and Exhibition, 1977Abstract This paper presents the past, present and future of deepwater exploration drilling (600 to 8,000'). Specifically presented are the technical achievements that were necessary to move beyond 600' water depths and to provide the capability to drill in 8,000' of water.

Optimization of Deepwater Drilling With Real-Time Operations
Proceedings of SPE/IADC Middle East Drilling and Technology Conference, 2007Abstract The following-up of drilling operations in "real time" from a remote location has been on the wish list of some drillers for quite a long time. In recent years, this has become a reality with phenomenal advances in digital technologies, satellite communications, remotely controlled systems, and collaboration centers that allow ...

Drilling Riser Integrity Assurance for Deepwater Floating Drilling
Offshore Technology Conference, 2017Abstract Objectives/Scope Historically, deepwater drilling riser challenges were always seen to be related to riser weight and metocean stresses. Consideration of the riser as a pressure vessel has been limited to production riser applications or smaller high pressure risers used for floating surface ...

Advanced Slip Crushing Considerations for Deepwater Drilling
IADC/SPE Drilling Conference, 2002Abstract Deepwater drilling trends are moving towards deeper water depths as well as deeper exploration horizons and reservoirs below the mudline. These trends have created various operational and well design challenges. This paper addresses a serious problem pertinent to the design of landing strings and drill strings for deepwater ...

Drilling Vessels For Deepwater Exploration
OCEANS '86, 1986This paper will present a new design of deep sea exploration utilizing synthetic composites. These materials can replace the basic steel structures, while also reducing the weight of the vessel and allowing for superior seakeeping abilities. The historical evolution of the offshore drilling rig and the advantages of the synthetic materials in the ...

Low Impact Drilling Fluid for Deepwater Drilling Frontier
Offshore Technology Conference Brasil, 2019Abstract One of the biggest challenges when drilling in deep water is the excessive dependence of drilling fluid rheological properties on temperature. Conventional drilling fluids often have high viscosity at the seabed temperature, which increases the Equivalent Circulating Density (ECD) and surge pressures when running pipe or ...

Pressured Drilling Riser Design For Ultra-Deepwater
Proceedings of IADC/SPE Drilling Conference, 2002Abstract This paper focuses on the design considerations of a pressured drilling riser that can be used with a surface BOP in deepwater. One key element to the development and reliable use of surface BOP drilling is this (riser) link between the seabed and the drilling rig.

The Vertically Moored Platform for Deepwater Drilling and Production
Journal of Petroleum Technology, 1978The general configuration, motion characteristics, and basic design principles of the vertically moored platform (VMP) are described. Two principles of the vertically moored platform (VMP) are described. Two example designs are presented with a description of fabrication and installation; cost estimates also are presented.
