Combining RSS, LWD achieves milestone in Abu Dhabi

By Ivor Sinclair, Weatherford International Characterized by harsh, carbonate formations inducing high levels of stick-slip and vibration, drilling and completion work in Abu Dhabi presents a unique set of challenges. Nevertheless, the Revolution rotary steerable system (RSS) and Precision LWD have been used by a major operator in the region to successfully achieve complex drilling objectives both on- and offshore. In the onshore Abu Dhabi case, the tools were used to drill and complete two water injection wells. In one of the wells, the tools were used to drill a horizontal section while staying within the zone of interest using real-time geosteering services. The well was planned with a vertical kick-off and doglegs up to 8º/100 ft, requiring performance at ...

Automation may be the key to next-generation, difficult-to-exploit wells

By Jon Ruszka, Baker Hughes INTEQ Today, operators faced with discovering and developing hydrocarbon reserves are facing more, and more extreme, challenges. Every year, reservoirs are becoming more challenging to find and exploit. Similarly, the environments in which these reservoirs are located are getting increasingly hostile – either because they are in remote areas or because they are positioned deeper below the Earth’s surface. In addition, the need to improve field recovery will intensify and the efficiency of drilling operations in relation to BOE produced will continue to be a measure of field operators’ success, irrespective of field size. As conventional plays deplete, we will exploit different reservoir types. Finally, there are the personnel challenges. Personnel safety will remain the ...

Downhole motors, wired pipe, LWD sensors enhance RSS results as service companies address cost concerns with simpler systems targeting land, shallow-water operations

By Linda Hsieh, assistant managing editor In February 2008, when Exxon Neftegas Ltd (ENL) completed the world-record extended-reach well on Russia’s Sakhalin Island — drilled with Baker Hughes INTEQ’s AutoTrak G3.0 system — the well’s measured depth of 38,322 ft (11,680 m) stood as a testament to how far rotary steerables had come. Once an unreliable tool that was exclusively deployed on the highest-end offshore projects, it was loved and hated at the same time — loved for its precise 3D steering capability and potential for improving drilling performance, yet hated for its limited reliability and added costs. Slowly but surely, especially in the past five years, rotary steerable technology has finally grown up. Nowadays, everywhere there’s drilling, rotary steerables ...

Gary Casswell, Pride International: In this business, ‘it’s all about the people you work with’

By Linda Hsieh, assistant managing editor While most 14-year-old boys in the ’60s spent their summers riding bikes or reading comic books, Gary Casswell spent his summer vacations on drilling rigs learning how to make hole. Thanks to his father’s job as a rig mechanic, Mr Casswell got an early start on everything from cleaning casing to mixing mud. “I loved it, couldn’t get enough of it,” recalled Mr Casswell, now vice president of Eastern Hemisphere operations for Pride International. By age 21, he had gone into Santa Fe Drilling’s assistant driller training program in Saudi Arabia. Within a couple of years, he had been promoted from assistant driller to driller and was “drilling exploration wells in Rub’ al Khali, ...

Commissioning of BP’s record-setting Atlantis platform completed BP announced it has completed commissioning of the Atlantis semi-submersible platform in the deepwater Gulf of Mexico and commenced the export of oil and gas from the deepest moored floating oil and gas production facility in the world. The water depths and reservoir structure make Atlantis among the most technologically challenging developments undertaken by BP,” said Andy Inglis, BP’s chief executive of exploration and production. “Start-up is an important milestone as we grow production from our strong upstream portfolio in the deepwater Gulf of Mexico and elsewhere in the world.” Production began with the commissioning of wells and facilities in October 2007. With gas facilities and export pipelines now fully commissioned, gas sales ...

Diamond Offshore announces new drilling contracts Diamond Offshore Drilling has been awarded four drilling contracts from Petrobras. The commitments for the four semisubmersibles could generate a combined maximum total revenue of about $2.3 billion and represent 22 years of contract drilling backlog. The Ocean Worker received a six-year commitment. It is currently working in Tobago on a six-month contract and is expected to begin work in Brazil in the third quarter of 2008. Three other contract extensions were: • The Ocean Yatzy received a five-year commitment for work expected to continue until the fourth quarter of 2014. • The Ocean Winner received a five-year commitment for work expected to continue until the first quarter of 2015. • The Ocean Alliance ...

Oil price keeps outlook upbeat, but don’t forget critical challenges

By Linda Hsieh, assistant managing editor TO THE AVERAGE energy consumer, the oil and gas industry probably looks like it’s sitting on top of the world with nary a dark cloud on its horizon. Oil prices are breaking record highs even as energy demand continues to grow. And all we’ve got to do is dig holes, pump out the oil and get it to a gas station. How hard can that be? Very hard, considering the declining production from maturing reservoirs. Even harder than that, considering the harsher environments we’re moving into (deepwater, ultra-deepwater, HPHT, arctic). And extremely hard, if we want to do it all without safety incidents with an increasing number of new and inexperienced personnel. Although oil ...
