  • Advances in Land Seismic Data Processing: Continuing the Conversation – June 28-30, 2022 May 5, 2022

    Z-Terra’s CEO and Chairman Mihai Popovici is one of the organizers of the “Advances in Land Seismic Data Processing: Continuing the Conversation” workshop on June 28-30, 2022 in Al Khobar, Saudi Arabia.  The event overview is below:

    Following the successful land processing workshop held in 2018 in Kuwait, this upcoming meeting aims to share updated practices and new advancements in land seismic data processing, both in terms of maximizing the value of legacy data and promoting advances in data acquisition technologies such as increased number of channels, novel source technologies, full azimuth, long offset, broadband, and nodal systems. Current issues affecting onshore seismic data, processing workflows, and existing limitations will be discussed. The technologies that utilize entire wave-field are of particular interest.

    Use of passive seismic and non-seismic data to enhance and complement land seismic data processing for imaging and sub-surface monitoring is certainly a related area of interest. Due to the increase in data volumes recorded on land, another relevant topic for the workshop is the use of Machine Learning (ML) in QC of very large data sets and in processing workflow to enhance quality and efficiency in order to expedite decision-making.

    Geoscientists with varying backgrounds will have the opportunity to exchange ideas, share their experiences, network with their colleagues, and learn new techniques. The workshop will cover associated theories and applications as well as case studies on land data. This will highlight ways in which we can maximize information and value from seismic data.

  • High-Tech Low-Tech – The Curmudgeon’s Column June 23, 2021

    An old Silicon Valley mantra postulates that money is not in technology but in the business application of technology.

    When I posted in LinkedIn a link to my Geophysical Society of Houston Technical Lunch in order to generate some publicity for my talk on Beam Tomography, one of the interesting comments from a colleague at a large service company was that Beam Technology is “a technology with many benefits that unfortunately is commonly regarded as old school / low tech.” I loved the comment because it allows me to talk about one of my favorite business concepts that I always look around to apply, and that is High-Tech Low-Tech. High-Tech is a term for new technology that incorporates advanced features. Low-Tech is the old school technology. I’ll start with an example, the story of the Nest thermostat.

  • Diffraction Imaging – The Curmudgeon’s Column November 8, 2020

    In the last post, I explained the title of the column comes from the book by Charles Murray The Curmudgeon’s Guide to Getting Ahead. With the Curmudgeon in mind, I have a few more comments to make about our life as Researchers, pushing the leading edge of technology in our industries. In small companies it helps to be a contrarian, to develop novel algorithms in areas overlooked by large research groups or the academic groups funded by them. One such technology that our group started working on a few years ago, nudged by the research group at Saudi Aramco, is Diffraction Imaging (DI). Aramco was looking for a company with a good quality commercial Kichhoff migration, since this particular DI implementation involves modifying a Kirchhoff kernel.

    Diffraction Imaging is a high-resolution imaging technology designed to image and identify in very fine detail the small scale fractures in shale and carbonate reservoirs that form areas of increased natural fracture density.
