Managed pressure drilling methodologies evolved over the years to address operational and economic problems inherent to conventional circulating systems that are open to the atmosphere. Most recently, the advanced closed-loop technology has swept into deepwater operations to help reduce risk…
Planning and information are key to the successful realization of Petrobras’ ambitious plans to hoist pre-salt production levels from the current 100,000b/d to 1.08 million b/d inside ten years. Jennifer Pallanich listened in as José Formigli…
Once in a while I would like to look inward and discuss technical advances in the industry or how things have evolved. In the case of hydraulic fracturing, the process has emerged as the premier production enhancement technique in oil and gas…
The AP Moller-Maersk Group's Maersk Drilling has signed a contract with the Keppel Fels yard in Singapore for the construction of two ultra-harsh environment, high-capacity jackup drilling rigs. The new rigs are targeting operations in water…
Pulse Structural Monitoring, a recent offshoot from 2H Offshore, is gearing up post Macondo to provide what it claims is the most comprehensive drilling riser monitoring service on the market, as Bill Clewes reports.Despite its environmental impact…
Coring practices and equipment used in the Gulf of Mexico's Lower Tertiary needed to adapt to formation conditions to improve on past recovery success. Petrobras' James Meyer opens OE's drilling & completion technology two-parter with a review…
Drilling system vibration was recognized as a potential cause of elevated drilling costs half a century ago. It has been thoroughly studied in the years since, and sound mitigation practices have been published. Shell's Mark Dykstra discusses the state of the art…
Field development prospects on the UK Continental Shelf are gathering momentum again, with Nexen (Golden Eagle, Blackbird), Chrysaor (Solan) and BG (Blake increased production) firming up North Sea project and environmental impact details in recent weeks…
A decade and a half after its Mars TLP started production, Shell is gearing up for the Mars B development and its centerpiece, the Olympus TLP. Russell McCulley talks to Robert Patterson, Shell VP upstream major projects for the Americas, about…
For this specially extended edition of his monthly OE column, Professor Michael Economides invited famed horizontal drilling pioneer Jacques Bosio to collaborate on a piece discussing the provenance of this breakthrough technology and its continuing influence on oil & gas well design today…
A configuration change-up on traditional spars could spell out some relief in wind load, drop the unit’s center of gravity, slim down the hull, and cut the amount of tripping time needed for drilling operations from a spar. OE’s Jennifer Pallanich…
Things are stirring on the UK continental shelf if the attendance at last month’s Pilot Share Fair in Aberdeen is anything to go by. More than 1000 people, including Meg Chesshyre, turned out to hear from major operators and contractors about their strategies for future North Sea projects…
By ensuring optimal hole size, well designs using solid expandable tubulars have a far-reaching effect on drilling, evaluation, completion and life-of-well solutions. Enventure Global Technology’s Kevin Waddell, Jerry Fritsch and Kristaq Mitrushi…
Another drilling contractor, Seadrill, recently put to the test DNV’s new standard for managing integrated software dependent systems. Wendy Laursen assesses the system’s scope for reducing software-related downtime on drilling units.There are…
