Case Study Presentation from the 3-D Seismic Symposium

Last month, nearly 400 geoscientists convened in Denver for the annual RMAG/DGS 3-D Seismic Symposium. The event provides case histories for geophysicists, geologists, landmen, and engineers who seek to stay abreast of new 3-D technology as applied to petroleum exploration and development. This year, our own Dr. Morgan Brown presented a case study showing how PSDM data provided key structural imaging benefits that reduced horizontal drilling risk in the Marcellus and Utica shale. Lucky for you, we recorded his presentation so if you missed the symposium you can still view it.

Upcoming Events & Presentations from NEOS

With the year in full swing and several industry events around the corner, we want to remind everyone to not miss your chance to catch our own Dr. Morgan Brown – an expert in seismic depth imaging – presenting at two upcoming events. If you aren’t able to make these events, not to worry; we will upload a recording of Morgan’s presentation in the coming weeks.

2017 3D Seismic Symposium – Wednesday, February 22 in Denver

Organized by the Rocky Mountain Association of Geologists (RMAG) and the Denver Geophysical Society (DGS), this year’s symposium promises a full agenda of informational presentations focused on seismic imaging in North America. Morgan will take the stage at 10:30 AM to present a prestack depth migration case study from the Appalachian Basin/Marcellus-Utica shale.

CSEG Technical Luncheon – Monday, February 27 in Calgary

The following week, Morgan will be presenting at CSEG’s luncheon. The lunch starts at 11:30 at the Calgary Petroleum Club.

 

About Dr. Morgan Brown
Morgan is a well-known evangelist for advanced seismic processing technology including PSDM imaging. As a Geophysical Advisor in Depth Imaging at NEOS, his role includes optimizing PSDM workflows and consulting on internal PSDM projects. Morgan received a Ph.D. in Geophysics from Stanford University and a B.A. in Applied Math from Rice University.

NEOS’ SIG Launches Frequency Enhancement Offering

The Seismic Imaging Group (SIG) at NEOS has launched a new seismic data processing offering.  This technique for structurally oriented frequency enhancement (SOFE) significantly improves the recovery of high and low frequency acoustic signal. The result is an improvement in the vertical resolution of seismic images and an increase in the quality and utility of the seismic data that geoscientists use for attribute extraction, inversions, and rock and fluid property determination.

According to Dr. Edward Jenner, Research Director at SIG,

SOFE works by applying a frequency-dependent filtering technique that uses the mid-range spectrum, in which we have the highest signal-to-noise, to guide the filtering and attenuation of noise in the low- and high-range frequency spectra, in which we have the lowest signal-to-noise.  The technique typically results in a significant increase in useable bandwidth of 30-50 Hz at the high-end of the spectrum, thus significantly increasing the resolution of the resulting seismic images.”

While SOFE will be of great value in almost every geologic setting, the greatest uplift will likely be realized by interpreters working in thin, stacked-pay reservoirs (such as those found in the Permian Basin) or those trying to image and determine rock properties in stratigraphic plays.

For those who will be at SEG in New Orleans next week, Dr. Jenner will be hosting an invitation-only Lunch & Learn on Tuesday October 20th.

Data before and after SOFE. a) input seismic section; b) seismic section after SOFE; c) input seismic section after spectral balance - note significant high-frequency artifacts; d) SOFE section after the same spectral balance as in (c) – note high-frequency artifacts are eliminated and the result is a broad-band, high-resolution, interpretable section that ties the well data.

NEOS Buys Onshore Seismic Data Processing Business

NEOS teaser homepage_FINAL
I’m not sure if you’ve seen it yet, but NEOS just announced our acquisition of the onshore seismic data processing business of ION Geophysical’s GX Technology group.

Click here to read the press release.

This transaction involves a group of about 25 Denver-based folks who originally started as AXIS Geophysics and which ION acquired back in 2002.  This team commercialized the technologies and workflows for anisotropic and azimuthal processing, which ultimately found great utility in fracture detection and sweet spot imaging for hard-rock and unconventional source-rock reservoirs.

More recently, the Denver office has incorporated many of GXT’s depth migration and tomographic imaging techniques into its workflows, positioning the entity as an industry leader in onshore depth imaging for complex fold- and thrust-belt geologic regimes, as well as pre-salt plays like those found in Kazakhstan and in the onshore basins along the South Atlantic Margin, including those in Angola, Brazil and Gabon.

As our loyal Sweet Spot readers know, NEOS has focused on non-seismic imaging methods since our launch in 2011. What you may not know is that we have long coveted having an in-house seismic capability, and this acquisition now provides us with the ability to offer a true multi-physics imaging solution to our customers.

DR_eye_candy_IL130Though this group – which will be known moving forward as the NEOS Seismic Imaging Group (SIG) – will continue to offer stand-alone data processing and imaging services, we are also excited about how we can extract maximum value for our customers by combining seismic and non-seismic measurements, attributes and methodologies.

One of the first obvious areas we’ll be working on is the incorporation of seismic attributes at the reservoir interval (e.g., rock brittleness, fracture density, fracture orientation) into our Predictive Analytics methods.  But of course there are many others, including the ability to undertake true multi-physics inversions.

Check back over the months ahead to learn more about this addition to the NEOS family.
