High strength alloys and connection options for extreme HPHT wells

Bruce Bradley, JFE Technology Center

Ultra-HPHT wells are challenging the limits of tubular performance, in terms of metallurgy and threaded connections. But higher pressures and temperatures are only part of the challenge. Carbon steel, hot-rolled chromium-based stainless steel, and cold-hardened materials are all options that must be considered to optimize economics in ultra-HPHT applications.

New workstring connection improves tubular performance, economics in horizontal wells

Keith Myers, Certus Energy Solutions

Conventional tubular technology has imposed performance limitations and financial strain on horizontal well interventions. Premature upset wear, extensive redress charges and moderate torsional ratings are of increasing concern.

Large-diameter completion string saves time on landing and intervention operations

Early subsea wells used API drill pipe, which was available on the rig, to land production tubing and completion equipment from the surface vessel to the subsea wellhead. As total depths approached 30,000 ft, pressures increased beyond the capacity of standard API drill pipe and rotary-shouldered connections with gas-tight, metal-to-metal seals. This led to the development of dedicated completion tubulars, starting in the early 2000s, but further improvements were still possible.

Newfoundland and Labrador shrug off mediocre market, as offshore projects proceed

Kurt Abraham, World Oil

Despite less than ideal oil prices, operators are proceeding with multiple field projects offshore Newfoundland, given their long timeframes. The exploration side of the local industry is also active, while provincial officials consider the next role for the long-serving, Bull Arm fabrication site.

Evolution of technology funding in the UK North Sea

Ian Phillips, Oil and Gas Innovation Centre

In 2014, the Scottish government created the Oil and Gas Innovation Centre (OGIC), as part of a greater £120-million technology development program. OGIC is part of the UK and Scottish government’s rapidly evolving support for oil and gas exploration. To date, the organization has funded over 40 projects, valued at over £2.5 million ($3.25 million).

Inflatables solve a multitude of downhole restriction issues

Tim Davis, TAM International

Advances in inflatable tools have enabled operators to rely on the technology throughout the life of a well. They can be configured as a packer or a bridge plug, be permanent or retrievable, and provide single-set or multi-set functioning. Because inflatables can have an OD two-to-three times the run-in diameter, they have a distinct advantage over conventional tools.
