Dwayne McClelland, Chevron Pacific Indonesia: Industry must stay on alert with safety, well control training

By Linda Hsieh, assistant managing editor Dwayne McClelland is a fourth-generation oilfield worker. His father worked on the service side with Weatherford for many years, eventually owning his own company as an oilfield manufacturer’s agent. His grandfather was a driller and toolpusher in southwestern Louisiana. And more than 100 years ago, his great-grandfather ran a team of mule-drawn wooden wagons that delivered tools to drilling rigs. You might say that drilling is in his blood. Mr McClelland, senior drilling advisor for Chevron Pacific Indonesia, said that he had already developed an interest in drilling from going out to rigs with his father in Germany, Austria and North Africa while growing up. During his senior year in high school, a three-day ...

Weatherford awarded 2 ½-year Sakhalin contract Weatherford International has been awarded a 2 ½-year contract with Sakhalin Energy Investment Company for tubular running services on its Piltun-Astokhskoye-B (PA-B) processing and production platform off the northeastern coast of Sakhalin Island, Russia. The contract includes Weatherford’s new OverDrive casing running and drilling equipment and services for up to 13 wells on the PA-B platform — part of Sakhalin II, one of the world’s largest integrated oil and gas development projects. Weatherford began providing conventional tubular running services for Sakhalin Energy on the Sakhalin II project in 2004 on the Molikpaq platform and mechanized tubular running services on the Lunskoye-A platform in 2006. To date, the company continues to work on these projects. ...

Creating oil patch professionals: Training standards in development to give workers deserved recognition

By Bill McPherson, Noble Drilling Services Inc “I am the age-old story of the oilfield. I am third-generation oilfield who started college and made some bad decisions and ended up working the past twenty-odd years in it… I have made a good living in the oilfield, but there has always been that little something missing … a college degree.” (e-mail from an oil patch professional) With the world’s thirst for oil and gas increasing every day, our industry has become more and more vital to not only national interests but also world interests. Hurricane disruptions have shown what impact our industry can have on the economies of nations. And, still vivid in the minds of the general public is the ...

World’s first subsea facility to separate, inject water, sand from wellstream goes on-stream at Tordis field The world’s first complete subsea solution for separating and injecting water and sand from the wellstream is on stream and creating added value at the Tordis field, said StatoilHydro. This technology is a breakthrough for a new generation of subsea solutions in the oil industry. The Tordis subsea development is part of a project that will improve the recovery factor for the Tordis field from 49% to 55%. This amounts to roughly 35 million bbl of oil, in addition to associated gas. The full potential of the subsea facility has not yet been realised due to unforeseen challenges with the injection well, but alternative ...

BP makes 15th discovery in ultra-deepwater Angola block Sonangol and BP have announced the Portia oil discovery in ultra-deepwater Block 31, offshore Angola. Portia is the 15th discovery that BP has drilled in Block 31. The well is approximately 7 km north of the Titania discovery. Portia was drilled in a water depth of 2,012 m, some 386 km northwest of Luanda, and reached 5,678 m TVD below sea level. This is the fourth discovery in Block 31 where the exploration well has been drilled through salt to access the oil-bearing sandstone reservoir beneath. Well test results confirmed the capacity of the reservoir to flow in excess of 5,000 bbl/day. Pride drillships awarded contracts by BP, Petrobras Pride International has ...

New IADC committee to tackle guidelines, stats for rig automation

Mike Killalea, group vice president & publisher Rig Automation is not only here to stay, it continues to intensify in sophistication and complexity. Mechanized rigs are increasingly common, observed Gregers Kudsk, vice president-engineering and projects for Maersk Contractors, speaking in a 5 March Plenary Session at the IADC/SPE Drilling Conference in Orlando, Fla. (4-6 March). In some areas of the world, he said, automation is not optional, but required. Compared with traditional technology, Mr Kudsk said, new technologies can save 20% or more in drilling time. He pointed out that only about 30% of total drilling time is spent drilling and tripping, while the rest is flat time. Therefore, our real opportunity for increased efficiency is by narrowing that 70% ...

IADC Advanced Rig Technology Committee holds 1st meeting The new IADC Advanced Rig Technology Committee plans to work toward guidelines and best practices for automated drilling systems, as well as examine standard methods of reporting reliability problems with advanced rig equipment. The committee held its inaugural meeting during the 2008 IADC/SPE Drilling Conference in Orlando, Fla., on 5 March. Automated drilling systems are increasingly common in today’s rig fleet. However, reliability can be problematic. The IADC committee will consider a wide range of issues, including: • Standardization of plug-and-play equipment electrical interfaces. • Guidelines for competency and HSE. • Guidance to drilling contractors on appropriate operations for automated systems. • Developing a database of reliability or failure statistics for key ...

IADC argues against lease suspensions The US Minerals Management Service held a workshop in New Orleans on 23 January to allow three Gulf of Mexico operators to make their case for “suspension of operations” when technology to exploit offshore leases is allegedly not available. IADC representatives attending the workshop concluded there’s no justification for expanding the criteria for suspensions of operations, and that MMS has sufficient authority to grant relief as needed. In its formal comment to the docket, IADC observed that the same so-called technological barriers found in the GOM deepwater frontier have been surmounted elsewhere in the world. IADC argues that operators who won’t fulfill their lease commitments by the end of their lease terms must return the ...

IADC, regulators address asset integrity in continuing effort to improve HSE

HSE is central to IADC’s mission on behalf of the global drilling industry. In pursuit of HSE improvement, IADC collaborates with all stakeholders – operators, service firms, government and, of course, drilling contractors. We have been honored to be recognized for our efforts in this regard, most recently by the International Regulators Forum (IRF) at its Offshore Safety Forum, held in Miami last December. At that event, we were recognized with the Carolita U Kallaur Award for Outstanding International Safety Leadership for our development of the IADC Health, Safety and Environmental Case Guideline. Discussion at the IRF event focused to a large extent on asset integrity of offshore installations. Distilled to its essence, this broad topic spans the overall ability ...

Real-time, 3D visualization drilling supervision system targets ECD, downhole pressure control

By Rolv Rommetveit, Knut Bjorkevoll, SINTEF Petroleum Research; Sven Inge Ødegård, Hitec Products Drilling eDrilling is a new and innovative system for real-time drilling simulation, 3D visualization and control from a remote drilling expert centre. The concept uses all available real-time drilling data (surface and downhole) in combination with real-time modeling to monitor and optimize the drilling process. This information is used to visualize the wellbore in 3D in real time. eDrilling has been implemented in an onshore drilling center in Norway and has been used on several drilling operations. This article focuses on utilization of an advanced flow model for real-time supervision and control of ECD and ECD-related effects. Real-time modeling The key elements of eDrilling are real-time simulation, ...
