Deepwater needs spur most advances in offshore rig designs

Although recent innovations in offshore rig designs tend to favor drillships and semisubmersibles, there has been some progress in developing new jackups


Shale Tech: Eagle Ford rig count down; operators cautiously bullish as permits, new wells soar

Firmly etched in Richard Stoneburner’s psyche is Oct. 11, 2008. On that doubly memorable Saturday, while the University of Texas aficionado was watching his football team dismantle then number-one-ranked Oklahoma University in their annual grudge match, word came down that the textbook geological evaluation of a young South Texas shale that he helped orchestrate had, likewise, delivered a winner.

Field testing CO2 foams, conformance control gels for EOR – Part 3

Part 3. Pilot tests of CO2 foams have been conducted for conformance control and mobility control purposes, and aqueous gel treatments have also been employed for conformance control during CO2 floods.

Lab tests for drilling equipment: Going beyond API standards

Some of today’s more challenging wells subject downhole equipment to conditions close to their physical limits. While API specifications and recommended practices serve as a basis for product testing, it is sometimes necessary to test for conditions not covered by those documents. Close collaboration between manufacturers and operators is essential.

Show Preview: ONS focuses on sustainability, diversification and security

As advancements continue to be made in offshore technology, and resources are discovered in new, ever-deeper waters around the world, Offshore Northern Seas (ONS) 2012, one of Europe’s premier oil and gas shows, will explore some of the varying challenges—economical, geopolitical and regulatory—in today’s offshore operations.

Optimizing horizontal completions with openhole packers

Part 1. Openhole packers have transformed from novel technology to a critical key for success, effective in different applications, including curing losses, controlling high-permeability zones and fractures, improving flow equalization, and controlling water and gas production.

Shale Tech: Provocative concepts in fracturing

Background. Provocation is an essential part of the creativity process. Faced with a mental or practical observation that contradicts and challenges the accepted norm, our mind is provoked to seek alternative explanations. Provocation can be deliberate, or compulsory, and forced by necessity. In either case, the process opens new avenues for learning and innovation

Regional Report - North Sea: The near-term outlook is bright in Norway and Ireland, while a mixed bag remains for the UK, Denmark and The Netherlands

Show Preview: Technology advances in exploitation highlighted at ShaleTech 2012

As the development of shale plays continues to evolve, both in the U.S. and other parts of the world, innovations are being made in shale exploration, drilling, completions and production.

Tracking hydrocarbon seepage in Argentina’s Neuquén basin

The integration of surface microbial surveys and gas chimney probability volumes is useful for detecting overlooked pay and unconventional resources in mature basins, such as the Neuquén basin.

High oil prices spur EOR activity

High oil prices and declining reserves of light crude are serving as the incentive to extract as much oil from existing reservoirs as possible.

Increased oil recovery possible with CO2 EOR in low-pressure reservoirs

A study in Kansas shows that near-miscible displacement is achievable in old, low-pressure, shallow oil fields, using CO2 injection.

Challenges and best practices for handling emulsions in chemical EOR flooding

Demulsifiers used to treat an emulsion resulting from a CEOR project greatly lowered water content in the oil phase and oil concentration in the water phase. This resulted in much more effective oil/water separation, with the production of dry oil and clean water at a pilot ASP flood.

Continuous time-lapse seismic aids thermal EOR project management

A seismic time-lapse field trial, in a heavy oil field in The Netherlands, has demonstrated that problems with near-surface variations between base and monitor surveys can be overcome by measures taken in acquisition and processing.
