BOEM: Northern Gulf of Mexico Deepwater Bathymetry Grid from 3D Seismic
The Bureau of Ocean Energy Management makes publically available a new deepwater bathymetry grid of the northern Gulf of Mexico, created by utilizing 3D seismic data which covers more than 90,000 square miles (Figure 1). The grid provides enhanced resolution compared to existing public bathymetry maps over the region, delivering 10 to 50 times increased horizontal resolution of the salt mini-basin province, abyssal plain, Mississippi Fan, and the Florida Shelf/Escarpment. To create the grid the seafloor was interpreted on over one-hundred 3D seismic time-migrated surveys, then mosaicked together and converted to depth in feet. The grid consists of 1.4 billion, 40-by-40 ft defined cells covering water depths –130 to –11,087 ft (–40 to –3,379 m). The average error is calculated to be 1.3 percent of water depth.
PGS: New First Break Article on Separated Wavefields
PGS Chief Scientist Andrew Long’s article in the June issue of First Break considers present and future opportunities of using separated wavefield data to illuminate, resolve, characterize and monitor reservoir properties and production in various marine settings.
There are some fundamental shortcomings in the traditional marine broadband seismic pursuit of uniform amplitudes over a large range of temporal frequencies, and deghosting achievable via many platforms contributes only modest amplitude improvements at very low and high frequencies.
When attention turns to the pre-stack domain the benefits of dual-sensor GeoStreamer® data and separated wavefields become more evident, particularly with respect to high fidelity reservoir characterization and reservoir monitoring.
The use of combined wavefields in wave theoretic imaging solutions extends the opportunities for enhanced subsurface illumination and resolution, and enables shallow reservoir characterization and efficient reservoir monitoring solutions not conceivable using conventional hydrophone-only seismic data.
When a larger range of spatial frequencies are also recovered using both explicit and implicit wave equation inversion solutions, ‘broadband’ marine seismic with separated wavefields clearly encompasses far more than the temporal resolution benefits considered a decade ago.
BP: Makes Trinidad Gas Discoveries
BP Trinidad & Tobago (bpTT) has announced that it has made two significant gas discoveries with the Savannah and Macadamia exploration wells, offshore Trinidad. The results of these wells have unlocked approximately 2 trillion cubic feet (tcf) of gas in place to underpin new developments in these areas.
The Savannah exploration well was drilled into an untested fault block east of the Juniper field in water depths of over 500 feet, approximately 80 kilometres off the south-east coast of Trinidad. The well was drilled using a semi-submersible rig and penetrated hydrocarbon-bearing reservoirs in two main intervals with approximately 650 feet net pay. Based on the success of the Savannah well, bpTT expects to develop these reservoirs via future tieback to the Juniper platform that is due to come online mid-2017.
EMGS: Reports approximately USD 2.4 million in sales
Electromagnetic Geoservices ASA (EMGS) announces that the Company has entered into various agreements with oil companies involving data licensing (prefunding and late sales) related to 3D EM data in the Norwegian Sea and Barents Sea in Norway. The agreements represent revenues of USD 2.4 million.
BP: OKs $500M Angelin gas project offshore Trinidad
BP (BP -1.2%) says it will move ahead with the $500M development of its Angelin gas project offshore Trinidad and Tobago, as it seeks to offset declining production in the area.
The project includes four wells and will have a production capacity of ~600M cf/day of gas that will be tied into the Serrette platform through a new pipeline, and the gas then will be sold into the domestic market or exported via the Atlantic LNG terminal; first gas from the facility is expected in Q1 2019.
BP also announces two significant gas discoveries offshore Trinidad with the Savannah and Macadamia exploration wells, which unlocked ~2T cf of gas.
BP’s Trinidad production has been in steady decline in recent years, sliding to 309K boe/day in 2016 from 461K boe/day in 2010; Trinidad accounts for nearly 10% of BP’s global production.
CGG: General Meetings of convertible bondholder 2019 & 2020 to be held on June 19, 2017
WesternGeco: Wins 4D seismic contracts from Engie in Norway
ENGIE E&P Norge has awarded WesternGeco two contracts for acquisition and processing of towed 4D seismic data in the production license 153, the Gjøa license, in the northern part of the Norwegian North Sea.
The acquisition will be performed with the vessel “WesternGeco Magellan”, and is planned to be completed by the beginning of August. The planned seismic survey is a repetition of a 3D survey acquired over the Engie E&P operated Gjøa field ten years ago.
License partners in PL153 Gjøa are: Engie E&P Norge AS (operator, 30 pct stake), Petoro AS (30 pct), Wintershall Norge AS (20 pct), Det Norske Shell (12 pct) and DEA Norge (8 pct)
CGG: Announces an agreement in principle on financial restructuring plan with main creditors and DNCA
CGG announces that it has reached an agreement in principle on a financial restructuring plan (the “Agreement in Principle”) which meets the Company’s objectives of (i) full equitization of the existing unsecured debt, (ii) extension of the maturity of the secured debt and (iii) financial flexibility to confront various business scenarios through, inter alia, additional new money (the “New Money”) and has garnered the support of the majority of its secured lenders, the majority of the holders of its Senior Notes and DNCA (in its capacity as a long-standing institutional shareholder, bondholder and convertible bondholder of the Company).
