The concept of seismic-while-drilling (SWD) promises so much, yet still the industry has realized so little of that promise. Drilling Contractor spoke with Robert Radtke, president of Technology International, about where SWD is at, and where it might be headed. Technology International has been working on a joint project with the US Department of Energy […]
By Maximo Hernandez, IntelliServ During recent industry conferences and workshops, reliability figures for the use of telemetry drill strings have been disclosed for the latest wells drilled around the world. These statements of technical performance have had the objective of confirming that the installations of the telemetry network hardware within double shouldered drill strings do […]
By Junichi Sugiura, Steve Jones, PathFinder Energy Services The advancement in deeper drilling programs and directional wells with multiple casing strings have urged the use of an expandable reamer in which casing pass-through ceases to be a restriction. Significant cost savings on enlarging the hole can be obtained by drilling with a rotary steerable system […]
By M Riyami, Petroleum Development Oman; J Edwards, E Vache, O Ojeiduma, S Johnston, Wael Darwish, Schlumberger Hydrocarbon basins in the Sultanate of Oman are located in the desert, where rig rates are low. Although this is not a typical environment for sophisticated drilling systems such as rotary steerable systems (RSS), use of this technology […]
By L. Fambon, G. Joffroy, TOTAL E&P UK Drilling infill wells on HPHT fields after a significant depletion has occurred represents a difficult challenge. It requires drilling from a cap rock remaining at or close to virgin pressure into a reservoir in which pore and fracture pressures have largely decreased due to production. No mud-weight […]
By Jeremy Cresswell, contributing editor In Q2 2008, Seadrill landed one of the most spectacular contracts ever awarded in offshore drilling. The client is Petrobras, the revenue potential is $4.1 billion across 18 rig years, and the rigs to be used comprise a trio of sixth-generation semisubmersibles currently in build. Moreover, strategically, Brazil is set […]
By Jeremy Cresswell, contributing editor As IADC members know all too well, patience is a prerequisite for success in the petroleum industry; it’s a basic fact. But some energy provinces take a lot more figuring out than others before the door to the prize is unlocked. A prime example is surely the Europe Union portion […]
By Magne Ognedal, Petroleum Safety Authority Norway Safety regulators in North Sea countries have pursued a fruitful collaboration for several decades through the North Sea Offshore Authorities Forum (NSOAF). Its members hold an annual working meeting where activities are summed up and new tasks are initiated and discussed. Most of the forum’s work is carried […]
It’s a fact that the North Sea is a mature oil province where exploration finds are often smaller compared with those offshore Africa or in the Middle East. But when oil is selling for $130 per bbl and bringing natural gas prices along with it to historic highs, being “mature” doesn’t seem to matter much […]
By Linda Hsieh, assistant managing editor A.J. Guiteau doesn’t know why, but he’s always liked education. He liked going to school and learning, so much that he earned an adult education degree from the College of Santa Fe in 1969 and then went back to high school as a teacher. But being a high school […]
