NOAA starts permit process for East Coast seismic surveys

The National Oceanic and Atmospheric Administration announced it is opening a 30-day public comment period as it prepares to act on five permit requests from geophysical companies to conduct seismic surveys for potential oil and gas off the Mid-Atlantic and Southeast coast.

In a notice issued Monday, the agency said its move is a step toward implementing President Trump’s executive order seeking to reopen offshore development on the outer continental shelf, from Delaware south to Georgia

The clock starts running with publishing the notice in Tuesday’s Federal Register. Reviving the process brings back permits that were sought last year from the Obama administration by three Houston-based geophysical companies –  WesternGeco LLC, ION GeoVentures, and Spectrum Geo Inc. — plus CGG, Paris, France, and TGS-NOPEC Geophysical Company, Asker, Norway.

Trump Officials Push for Atlantic Oil Exploration

Trump Officials Push for Atlantic Oil Exploration Using Harmful Seismic Blasting. Permits Would Hurt Endangered Whales, Open Way to Offshore Drilling Opposed by East Coast Communities.

The Trump administration today issued draft authorizations to five companies to search for oil off the Atlantic Coast — from Florida to Delaware — using loud seismic airgun blasts that hurt whales, dolphins and other animals. The exploration activities are the first step to opening the Atlantic to new oil drilling.

“Deafening whales and dolphins to hunt for dirty oil in these sensitive coastal environments is reckless and cruel,” said Kristen Monsell, an attorney at the Center for Biological Diversity. “Seismic blasting is opposed by people along the East Coast who don’t want the oil industry wreaking havoc in the Atlantic. It’s outrageous that the Trump administration is catering to Big Oil by ignoring the needs of wildlife and coastal communities.”

The proposals would allow the firing of seismic airguns from ships every 10 seconds, 24 hours a day, seven days a week at a noise level that would rupture a human eardrum. Nearly 100 municipalities from New Jersey to Florida have adopted resolutions rejecting seismic blasting off the East Coast. And more than 40,000 local businesses and business associations have publicly opposed it, citing threats to marine life and local economies.

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.
