Schlumberger-TESCO offer directional casing while drilling

Most casing while drilling (CwD) is done by attaching a non-retrievable bit to the bottom of the casing and leaving the bit in the hole. Directional casing while drilling (DCwD) uses a steerable BHA that is retrieved, making DCwD a viable alternative to conventional directional drilling in depleted or mature fields that have severe lost-circulation and wellbore stability problems, said Schlumberger during a press conference held at its exhibit booth on Tuesday.

Well construction in mature fields with standard drillpipe sometimes requires extra casing strings to avoid well stability problems caused by depleted formation pressures. Because they improve wellbore stability, the DCwD techniques developed through collaboration between Schlumberger and TESCO may reduce the number of casing strings needed.

IADC offers tools to build a well control culture

Opening the Health, Safety & Environment technical session on Tuesday afternoon, Steve Kropla, IADC group vice president – operations & accreditation, discussed the tools that IADC provides for companies to build a well control culture. WellCAP, the Well Control Accreditation Program, establishes core curriculum for well control training. It is industry-driven, developed by operators, contractors and service companies and designed for global application. It provides building blocks for well control competency through courses at several levels: introductory, fundamental, supervisory and the newest WellCAP PLUS.

Pride awarded multi-year deepwater drilling contracts from Petrobras, BP

Pride International announced that it is continuing the expansion of its premium deepwater fleet with a multi-year contract award from a subsidiary of Petrobras, for the construction and operation of an advanced-capability, ultra-deepwater drillship in support of Petrobras’ international exploration and development drilling projects. Additionally, Pride is expanding its deepwater drilling operations and its geographic reach in deepwater drilling basins to the strategically important US of Gulf of Mexico with the award of a five-year contract from a subsidiary of BP.

Deepwater drives Petrobras future production

Petrobras’ future production will be deepwater-driven, said João C.A. Figueira, upstream senior vice president for Petrobras America, in a speech to the Marine Technology Society on 24 January 2008 in Houston. With large new discoveries in pre-salt reservoirs such as Tupi and Jupiter, "deepwater is where we’re seen to grow in Brazil."

Offshore production in 300 m of water or deeper has grown significantly since the early 1990s. In fact, without deepwater production, he pointed out, Petrobras would be producing only about 500,000 bbl/day — far from the 2.367 million bbl equivalent/day it now averages. By 2011, Petrobras aims to be producing 2.374 million bbl equivalent/day.

David Payne calls for elimination of diverters

Chevron’s David Payne calls for elimination of diverters, rethinking of well control practices

ImageIt’s time to rethink many of the industry’s well control practices, urged Chevron’s David Payne at the recent IADC Well Control of the Americas Conference. Traditions must be set aside, he said, in order to make progress on issues such as diverter use, cementing, managed pressure drilling and personnel training.

Quoting American author John Steinbeck, Mr Payne reminded the audience that deeply accepted practices could take surgery to remove. “I submit that it may be time for surgery,” he said.

The following are four issues Mr Payne, Chevron vice president global drilling & completions, challenged the industry to rethink.
