GOM deepwater case studies: Hybrid bit minimizes vibrations, increases ROP, directional control

Polycrystalline diamond compact (PDC) bits and traditional roller cone bits can both face numerous challenges when drilling in the deepwater Gulf of Mexico (GOM). These range from poor drilling dynamics and gumbo-related-balling problems to drilling salt efficiently. The resulting nonproductive time (NPT) and compromised drilling speeds can challenge economic recovery in today’s environment. However, in Q1 2016, deepwater operators have used a new hybrid drill bit technology to reduce drilling times in extreme GOM wells.

Along-string measurements enable critical decisions, understanding of open, cased hole on structurally complex Norwegian North Sea field

With the development of a new field in the Norwegian North Sea, a major operator is taking on a complex task. The field was initially discovered in 1975 but proved too difficult to develop at the time. The field consists of an oil reservoir and several deeper, structurally complex, high-pressure gas and condensate reservoirs. Long horizontal wells are required for developing the oil reservoir, while several deviated wells will be drilled to unlock the gas and condensate reserves. Wells are drilled with restricted pressure windows and present a risk of both severe losses and influxes.

Statoil to farm into exploration licenses in Turkey Statoil has entered a binding letter agreement for two exploration licenses in the Thrace region in the northwestern part of Turkey.  The exploration licenses cover an area of approximately 540 sq km. Statoil will have a 50% interest in the Banarli licences, while the operator Valeura Energy, a Canadian exploration company, will keep the remaining 50%. The shallow formations above 2,500 m will be 100% retained by Valeura. The first phase of the work program includes the commitment of drilling one exploration well, with spudding planned for  late 2016 or early 2017. The agreement is pending governmental approval, which is expected by the end of September 2016. BP ramps up production from ...

The IADC North Sea Chapter (NSC) gathered for its Annual Safety Awards Ceremony on 22 April in Aberdeen. NSC Co-Chairmen Ivor McBean of Diamond Offshore and Gary Holman of Awilco Drilling welcomed a large turnout to the event. Guest speakers were IADC President Jason McFarland and Steve Rae, Vice President QHSE, Archer. “Everyone is aware of the extremely difficult times the industry is facing, and despite the challenges and uncertain future in terms of oil price and activity levels, the industry will continue to focus on the most important aspect of our business – the safety of our personnel,” Mr McBean said.

Perspectives: Siv Hilde Houmb, Secure-NOK: Fortify cybersecurity to avoid downtime

Growing up on a dairy farm in Norway outside of Lillehammer, Dr Siv Hilde Houmb learned how to ski at an early age and dreamed of competing in the Olympics. When a torn knee ligament sidelined her skiing career in 1993, Dr Houmb initially opted to forge a career in sports science and sports biomechanics. However, during her studies at Telemark University College and the Norwegian University of Sports and Physical Education from 1993-1994, she found herself increasingly fascinated by something entirely different – computers. “A computer is logically built. It is made by people, which means it has a finite defined state that it can work in, so you can learn everything about the computer. You can master it,” Dr Houmb said.

Can US land repeat zero fatalities if market rallies?

Attendees at the 2016 IADC Drilling Onshore Conference on 19 May were treated to a bit of good news during the market outlook session: The oil and gas industry is right at the beginning of a multi-year cyclical upswing. That’s according to Marshall Adkins, Managing Director for Raymond James and Associates. In fact, Mr Adkins said there is potential for the US rig count to average approximately 1,000 for 2017 and 1,300 for 2018. Those would be significant improvements over this year’s dismal rig count, which was hovering in the high 300’s as of May.
