Safer, faster, more efficient, more productive, more cost-effective and simpler interfaces top the technology wish lists of many in the offshore oil & gas sector over the next decade, as Jennifer Pallanich reveals in part two of this month's special survey…
One-trip solutionBaker Hughes last summer deployed a drilling system featuring a TORXS expandable liner hanger package with an EZCase casing bit system to assist an operator bedeviled by a problem zone. The unidentified operator was unable to…
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…
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…
Post-Macondo efforts to improve well containment capabilities on both sides of the Atlantic moved into higher gear last month.In the US it was confirmed that Technip will handle front- end engineering and design of a proposed subsea well containment…
The US lifted the six-month moratorium on deepwater exploration in October, while codifying new rules governing drilling safety and well control. Russell McCulley looks at what the new regulations could mean for oil & gas companies doing business in the Gulf of Mexico…
Long used in deepwater mooring, synthetic ropes are increasingly being employed in deepwater heavy lift operations. Russell McCulley talks to Samson's Dennis Sherman and Offspring International director Dave Rowley about the technology advances that are changing techniques…
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…
Global demand for floating hardware continues apace. David Morgan and Meg Chesshyre review recent support & supply sector initiatives and innovations targeting offshore platforms and rigs.Drilling riser departure A high pressure marine riser…
Conventional solids control methods are inadequate to manage low-gravity solids smaller than 8-10 microns. M-I Swaco’s Rich Cook discusses a new solution, recently successfully employed in West Africa, that helps manage these solids while keeping excess rig space to a minimum…
The risks associated with placing complex open hole completions across the reservoir are increasing. Deep Casing Tools’ Mark Presslie explains why and describes how a new tool assists the first-time placement of liners or completions.--Over the past two decades…
With well costs escalating to consume up to half of a project’s funding, operators are seeking ways to trim costs. During IADC’s Deepwater Drilling conference in Rio de Janeiro in March, operators discussed some of their strategies to trim costs…
The importance of battery selection for demanding downhole electronics applications, in particular measurement-while-drilling tools, is discussed by Saft’s Wayne Pitt.As oil companies strive to reap the maximum potential from their prospects…
BJ Services entered the multizone single trip completion market in 2005, when it began designing its ComPlete Multizone Single Trip (MST) system in response to a pair of operator requests.--‘One operator had multiple reservoirs that were of similar pressure but separated by numerous shale layers…
