When properly spaced in the drillstring, the Hydroclean tool has shown to reduce operating costs and non-productive time up to 20% as a result of hole-cleaning efficiency gains achieved while drilling large holes in highly deviated wells. A new drill pipe design incorporating hydromechanical cleaning features in each tool joint is now available to address ECD and annular pressure issues encountered while drilling horizontal and ERD wells.
The easy oil has already been produced. Today, drillers are going deeper, into harder, more abrasive formations. One challenge for drill bit designers is to create polycrystalline diamond cutters (PDC) with greater wear resistance without sacrificing impact resistance. And, although fixed-cutter bits serve most of the drilling market, traditional roller-cone technology is still undergoing development, with emphasis on reliability and improved rates of penetration.
To reach reserves in the Odoptu field, located offshore Sakhalin Island, Russia, ExxonMobil, as operator of the Sakhalin 1 project, drilled nine extended-reach wells from the Sakhalin Island shore, culminating with the record-setting OP-11 well. Lessons learned on these wells will be useful for designing future extreme ERD wells.
Part 2: Part 1 of the Global LNG report covered how demand is rising through economic growth in Asia and shutdown of the nuclear power industry in Japan. Part 2 covers the supply side, where growth is coming from the Middle East and Australia through planned expansions and the unexpected LNG export bonanza from North America.
Despite being home to some of the most prolific gas wells in the U.S., the once-celebrated Haynesville-Bossier shale has been relegated to little more than an afterthought, as cellar-dwelling commodity prices and comparatively excessive drilling and completion costs force even the most resolute operators to shut in and await better times.
A multi-stage treatment plant, designed for maximum water recovery, minimal effluent volumes and 99% availability, allows Sasol to support expanded synfuel production while reducing raw water usage.
A multidisciplinary model, which focuses on geographically distributed intellectual talent allocated and clustered in real time to provide on-demand technology development, promises to help ease the shortage of scientific and engineering professionals in the Western Hemisphere.
Results in a dozen key states may determine the political landscape in Washington, with major implications for oil and gas companies.

Shell’s GeoSigns software platform provides solutions to build a more accurate picture of the subsurface by visualizing and extracting information from data, rather than simply averaging it through various processing steps into a single data point.

The recently launched IsoMetrix service delivers isometrically sampled point-receiver seismic data in both crossline and inline directions, capturing the wavefield in three dimensions and providing highly accurate images of the subsurface.
With exploration activity booming and new technologies being developed to better assess resource potential, the Society of Exploration Geophysicists (SEG) 2012 Annual Meeting will bring together industry professionals from all over the globe to discuss the challenges, opportunities and innovations in the exploration business.
Applying established, recently developed technologies, many attributes (structural, rock property and anisotropic) can be generated from seismic data reconstructions, including full-azimuth angle gathers. When properly processed, imaged, analyzed and interpreted, seismic data become a vital source for exploitation of shale plays.
