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 recently completed a study over 1,000 square miles of Southern Colorado to identify areas that may contain CO2 reservoirs. Airborne magnetic and EM (ZTEM) data were collected and integrated with proprietary seismic and well data, as well as public domain ground gravity data. With a more quantitative integration using Predictive Analytics methodology we were then able to highlight areas that may have a higher potential to host CO2 reservoirs. Join us at the SEG Technical Program next week to gain more insight into this study.
Be sure to grab your April issue of First Break, and turn to this month’s special topic: EM & Potential Methods, where NEOS discusses the results from resistivity imaging using ZTEM and MT data in the geophysical study of a ~2900 km2 region of the northern Raton Basin in southern Colorado.
Because of the land access and permitting issues, as well as the large amount of terrain needing to be traversed during the geophysical survey, we decided to incorporate a dense airborne ZTEM survey along with the sparse MT stations.
Published in the January 2016 issue of EAGE’s First Break magazine, NEOS’ Seismic Imaging Group (SIG) discusses a frequency-dependent filtering technique that can significantly increase the available bandwidth of the seismic data. Click here or on the image above for the full article.
NEOS identified four distinct play types in the 6,000 sqkm area assessed on the Lebanon neoBASIN project:
A Triassic interval (BLUE) which is geologically similar to the gas and condensate fields of Syria’s Palmyride Belt to the northeast of the survey area;
A deeper (and potentially more gas prone) Paleozoic interval (PURPLE) also analogous to the Palmyride fields;
A Triassic interval in the near-offshore (BRICK RED) which is likely to be gas prone;
A Jurassic interval (YELLOW) which is geologically similar to the oil & gas fields producing south of Lebanon.
The locations on the image above are intentionally disguisedin terms of their geo-spatial locations and size (some of the areas shown above are depicted as being smaller compared to those actually assessed as prospective); actual locations of these highgraded play types would, of course, be revealed to licensees of the Lebanon neoBASIN Knowledge Library.
It is interesting to note that the actual interpretation suggests that several areas are prospective for multiple play types, meaning we have ‘stacked plays’ that should reduce the overall exploration risk in these locations given the possibility of multiple targets.
