After a decade of R&D spanning the globe, a new class of marine seismic technology has now been commercially deployed. Nina Rach spoke with Chris Cunnell of Schlumberger. In an ideal world, a seismic survey would have a grid of sensors across the full area of interest…
The latest appraisal well on the giant Johan Sverdrup field in the Norwegian North Sea found a deeper reservoir thickness than expected, said operator Lundin Petroleum AB (Lundin Petroleum). Appraisal well 16/3-7, located in the south-eastern part of PL501…
Norway's PG Marine Group is to provide six of its PG-MACS tanks for a newbuild dual-fuel platform supply vessel (PSV). The vessel, to be built at the Remontowa Shipyward, Romania, will be operated by Siem Offshore on long term charter to Norske Shell…
Shales are very fine-grained, clastic rocks that lose porosity through compaction. Sedimentary basins typically contain about 70% shale, Figure 1. Quantifying shale properties helps with predrill geologic and seismic interpretation, basin modeling…
A subsidiary of Atwood Oceanics has ordered a fourth ultra-deepwater drillship from South Korea's Daewoo Shipbuilding and Marine Engineering (DSME). The vessel, to be named the Atwood Archer, will be identical to the previously ordered Atwood Advantage…
The GTI and 2s’ DMPTs ease construction and interface with the vessel because they can be built in Huisman’s Schiedam fabrication hall and then skidded on the quayside, where it can be tested, before a single lift onto the vessel, says Huisman…
At OTC Fincantieri unveiled a new next generation drillship design, Overdrill, created with support from Norway’s Aker Solutions. The vessel, at 208m long and 40m wide, accommodating 210 people, aims to be smaller than existing units through…
Chevron and its 50:50 joint partner Shell have scored two gas finds in the Exmouth Plateau of the Carnavon Basin off Western Australia. Pinhoe-1, drilled to 13,396ft TD, encountered 197ft of net gas pay in the Barrow and Mungaroo Sands. The Arnhem-1…
Ocean Riser Systems has joined forces with Enhanced Drilling Solutions, a division of AGR Group, to form AGR EDS-ORS. The move follows AGR’s agreement to purchase the entire shareholding in ORS, subject to financing and board approvals. The transaction was expected to complete in late August…
Statoil may not have the biggest R&D budget, but company officials say the operator's technological track record on the Norwegian continental shelf will help it push recovery rates to new highs and create the first subsea factory, including seafloor separation…
Surface logging company Empirica, a member of Reservoir Group, launched two new technologies that the company expects will trim significantly the time it takes to sample and view well data.Dual Flame Ionised Detection (Dual FID) technology is a high-speed chromatograph…
Schlumberger last month announced the availability of two high-temperature additions to its reservoir characterization portfolio: the PressureXpress-HT reservoir pressure service and MDT Forte-HT qualified, rugged,high-temperature formation sampling and pressure system…
The mix of orders for all categories of drillings rigs continues, with Asia Pacific and Middle East shipyards and their overseas affiliates indicating a marked drift away from jackups and towards ever larger semisubmersibles and ultra-deepwater drillships…
An internal Transocean investigation into the explosion and loss of the Deepwater Horizon found that the tragedy was the result of ‘compromised' well integrity due to a series of well design, construction and temporary abandonment decisions made by operator BP…
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…
