By Linda Hsieh, assistant managing editor A critical issue is emerging on the environmental front that could result in serious consequences for drilling contractors and their operations: biofouling. Sometimes called “invisible pollution,” biofouling occurs when organisms attach to a surface – such as the hull of a ship – and get introduced into foreign ecosystems […]
By Gary Rytlewski, Schlumberger A new method of completing multiple-layer formations has been successfully tested in the United States and Canada. This new method places sliding sleeve valves in the casing string and completes the well with normal cementing operations. The sliding sleeve valves are opened one at a time to fracture layers independently without […]
After three extensions, the bid deadline for the seventh round of India’s New Exploration Licensing Policy (NELP) is now set for 30 June 2008. A total of 57 blocks have been offered for bidding, including 29 onshore blocks, nine shallow-water blocks and 19 deepwater blocks. Announced in December 2007, NELP VII has been heavily promoted […]
By Linda Hsieh, assistant managing editor Vietnam-based PV Drilling is gearing up to be a serious offshore player – just in time, since Vietnam is gearing up for some serious offshore drilling. Just six years ago, PV Drilling – or Petrovietnam Drilling and Well Services Corp – was a company providing small-scale services such as […]
By Mike Killalea, Editor & Publisher Drilling in the Gulf of Thailand (GOT) is not only high-volume work, but presents considerable technical drilling-and-completion challenges. Chevron, the major operator in the GOT, drills some 40% of its global footage there – that’s right, 40%. In 2007, that constituted 3.7 million ft and 310 wells, and the […]

“The challenges have shifted,” said Mike Brasic, who retired from BP in May 2008 as lifting adviser and as HSE manager for BP Sakhalin. First, there’s the people problem. “The level of experience among employees has gone down as the level of activity has gone up. That’s presenting challenges with competency that the industry must […]

By Chad Mason, Caleb Rickabaugh, Eric Olson, Hughes Christensen Certain formations create unique challenges for operators drilling directional applications with roller cone bits. In western Canada, for example, interbedded formations of hard sandstone, siltstone, shale and chert have frustrated operators using conventional tungsten carbide insert (TCI) bits to drill a directional wellbore. In addition to […]
By Jerry Greenberg, contributing editor Designing a drill bit with the correct configuration and hydraulic performance for a specific application has everything to do with a well’s success. A wrong bit for the application can result in low rate of penetration (ROP), inefficient hole cleaning and expensive wells that sometimes won’t reach the operator’s geological […]
