Chevron drillship Pacific Sharav arrives in Gulf of Mexico

Chevron Corp. reports that the deepwater drillship Pacific Sharav has arrived in the Gulf of Mexico to work under a five-year contract with Pacific Drilling.

Serica encounters oil offshore Morocco

Serica Energy plc confirms that the SM-1 well in the Sidi Moussa block offshore Morocco has reached a TD of 2,825 m (9,268 ft) measured depth below rotary table, and encountered oil. Preparations are under way to perform cased-hole testing.

Transocean rig to plug Svalin well in North Sea

Petroleum Safety Authority Norway has approved Statoil’s plan for permanent plugging of an exploration well in the Svalin field in the North Sea block 25/11.

MPD and closed-loop techniques solve drilling challenges off West Africa

A complex set of challenges offshore West Africa has defied drilling efforts for more than 40 years. Multiple attempts in the area's high-pressure/high-temperature and regressive pressure regimes using conventional methods have been unable to construct a wellbore to total depth. The solution came with an unusual scope of managed pressure drilling (MPD) operations and closed loop well construction techniques.

Liner drilling enables operators to reach new depths

The process of liner or casing drilling, in which the well's liner or casing string is used as part of the drillstring, can be a cost-effective solution to address many drilling challenges. Liner/casing drilling is an integrated services solution that can shorten drilling time and costs, reduce non-productive time, lower the risk of drilling through trouble zones, and help ensure that the liner reaches total depth.

Offshore at 60: The Blue Water breakthrough

In January 1962, a strange contraption under lease to Shell Oil, called the Blue Water 1, spudded a record-setting offshore well in 297 ft (91 m) of water in the Gulf of Mexico. The maiden voyage of the Blue Water 1 took place a month before NASA astronaut John Glenn became the first person to complete an orbit of the earth. Both missions revealed a newfound human ability to explore frontiers beyond the comfort of terra firma. On Aug. 14, 1962, Shell Oil dramatically disclosed the details of its new "floating drilling platform."

Collaboration takes industry to new technical highs, greater depths

Since its inception in 1991, DeepStar has served as an incubator for collaborative development of technologies that enhance deepwater exploration, drilling, and production. DeepStar's approach to technical collaboration has delivered advances across the deepwater E&P spectrum, from reservoir appraisal, ultra-deepwater drilling and completions, flow assurance, subsea processing solutions to floating structures and life extension. Some of the key research initiatives under way in its Phase XII development are described.

RPSEA continues technology advance with ultra-deepwater R&D projects

The business of advancing technology continues as the Research Partnership to Secure Energy for America (RPSEA) moves forward with its transition into the role of technical coordinator under National Energy Technology Laboratory/US Department of Energy management in 2015. RPSEA's Ultra-Deepwater Conference recently held in Houston not only reviewed the status of programs under way, but also took a look ahead at how the organization might function in the future.

ONS 2014 highlights next-phase deepwater drilling, subsea recovery challenges-full

Deepwater engineering contractors Aker Solutions, Baker Hughes, GE, and GVA outlined their visions of the way forward at the recent Offshore Northern Seas exhibition in Stavanger, Norway.

Australian research aims to reduce pipeline, drilling costs

Australia has invested heavily in the oil and gas industry but with increasing capex and ever-increasing demand, the country is focusing heavily on R&D to help mitigate costs while continuing to attract foreign investment to exploit its oil and gas reserves. Australian researchers have pinpointed three areas in which costs can be decreased through innovation and new technology.
