By Anne Sevignon and William Gamisans, VAM Drilling The evolution of drilling programs has driven the industry to develop more suitable solutions adapted to extreme and aggressive environments such as sour service. High-strength drill pipe is necessary to achieve deeper drilling objectives, even if the sulfide stress cracking susceptibility is an acknowledged concern starting with […]
While workplace safety is a priority for drilling companies, as it should be, MB Century has identified one often-forgotten area where safety messages and efforts should be targeted – the home front. MB Century (formerly Century Resources), which provides drilling rigs to the Australian and Asia Pacific regions, has implemented several best practice safety systems […]
By Ron Clem, Executive Training International Safety leadership has been the “buzz” phrase and a major focus for most companies over the last few years. Organizations strive to improve HSE performance by adopting new strategies, training initiatives and slogans to reach “Goal Zero” where “no one gets hurt.” Historically, the worldwide oil and gas community, […]
The drilling industry set another record with the lowest ever lost-time incidence (LTI) rate of 0.53 in 2007, a 5% improvement over 0.56 in 2006. The number of fatalities decreased as well, from 29 in 2006 to 23 in 2007. These are worthy achievements in an industry where rig demand continues to increase, as do […]
By Ian Hudson, Transocean We have come a long way in the drilling industry over the last few years in both technology and HSE performance. As pressure mounts to find more petroleum and to open up new areas for exploration drilling worldwide, our industry is experiencing an unprecedented period of growth, with many newbuild offshore […]
In today’s high-cost drilling environment, the lack of integration of valuable pore pressure or other reservoir information can cost a company millions of dollars, said Colin Sayers, scientific advisor for Schlumberger’s geomechanics group. He cited an example of one oil company where the geophysics department never told the drilling department about a small fault above […]
Pore pressure knowledge is critical when designing a well. It’s unlikely that anyone in this industry would argue with that. Pore pressure drives the casing design, which drives the well plan, including hole sizes and mud weight. An inaccurate pore pressure model could even lead to a well control event, causing financial losses or, worse, […]
By Steven Radford, Will Thompson, Hughes Christensen; Mark Jenkins, INTEQ In the deepwater Green Canyon section of the Gulf of Mexico, an operator lost 10,000 bbl of synthetic oil-base drilling mud in one well before finally abandoning the project. In cooperation with two Baker Hughes companies – Hughes Christensen and INTEQ – the operator began […]
By Jeremy Cresswell, contributing editor The name TOTAL is synonymous with West Africa, and for sure the region ranks as the French group’s number one theater of activity. Moreover, the company has an excellent exploration track record and reputation as a technology frontier buster when it comes to developing discoveries. While many of the headlines […]
By Jeremy Cresswell, contributing editor Africa is always in the headlines. The stories are rarely positive, and that’s a terrible shame given the extraordinary richness and diversity of this vast continent. But this review is a positive story, and our first stopping point is Mauritania. From Mauritania in the north through “Golden Crescent” states like […]
