In-Depth Compressive Seismic, Inc

As oil prices remain high, don't you want to try the Patented CS Acquisition Technology to acquire/recon/process/interpret some seismic data and drill some wells? If you say yes, visit In-Depth Compressive Seismic, Inc. & contact us! Since 2016, following the medical imaging breakthrough (e.g., MRI), In-Depth scientists have developed/parented the Compressive Seismic Data Acquisition technologies with MC-Maps and data CS-Recon using EPOCS. EPOCS strictly uses the genuine L-1 plane wave decomposition, and CS-Recon is done repeatedly during time processing, on raw, after static correction, before the ground roll, and before PSTM. Talk to us before you plan to do a CS project! Refrain from letting amateurs use L-2 moveout-based interpolation to destroy your CS data; L-2 doesn't work for CS! Following our patents, (1) we start from a dense conventional regular acquisition grid (corresponding to the initial/small MC-Map values ~ 0). (2) By minimizing the MC-map values, we optimize the CS design by "removing" points. The regular under-sampled survey may reach a maximum MC-Map value of ~1 (see Fig 6, c & e, 2010 Naghizadeh and Sacchi, Geophysics); removing points will usually increase the MC-Map values. (3) The optimal CS Acquisition design is achieved after some iterations as the MC-Map values approach 0, i.e., the blue color on the MC-Map. (4) After data is acquired, some CS-processing Companies can repeatedly CS-Recon your data back to the dense grid at different preprocessing stages and carry out the Kirchhoff/RTM/FWI processing/interpretation.

What does the MC-map mean for Compressive Seismic? Joel Latchman's article here explains it by comparing the (1) conventional grid, (2) randomized jittered design, (3) randomized gridded design, and our patented (4) optimized gridded design. Don't hesitate to contact us at info@indepthgeo.com. We'd love to arrange a private presentation on Seismic Imaging and Compressive Seismic Acquisition and Processing for you! Also, thanks to our sales team: Peter Eick, Pete Bridge, and King Sim Lee.

Our patented 2D CS-Acquisition (based on 2D MC-Maps) and CS-Recon technologies have benefited us greatly in recent years. These include the newly acquired Regular Indexed CS data and the Designed Random Acquisition or Conventional Seismic Data with a Certain Level of Randomness in source/receiver positioning. Like CS-medical imaging, CS-seismic data processing takes advantage of these precious CS-friendly source/receiver positioning due to the optimal CS design or the much less desirable randomness. Sadly, some (if not most) of today's commercial seismic processing software packages are "CS-blind", thus suffer from unnecessary aliasing. As a result, these "Avoidably-aliased Signals" have been treated as Noise and are filtered/muted out. This unnecessarily reduces the resolution of the product; what a waste! (1) To maximize the benefit like medical-CS, with a modern/optimal "2D CS Acquisition for Resolution" (Fig 2) -- see In-Depth's CS publications https://lnkd.in/gJKjiVrW -- In-Depth recommends a 50%*dx and 50%*dy (4X) CS-Recon (Figs 1 & 3). (2) Less ideal but still significantly beneficial for human-designed or mother-nature's Random Acquisition, In-Depth has invented and recommends the patented 2D MC-Map technology to estimate the optimal recon grid. Table 1 (Jiang, 2019) gives an example of ~75%*dx and ~75%*dy; this means we can deliver much higher resolution, e.g., (1) 4X-resolution for Resolution 2D CS data and (2) ~1.75X-resolution for 2D Randomly/Conventionally Acquired data using our patented CS-Recon workflow. At In-Depth, the CS-Recon to (1) the CS-Acquired and (2) Conventionally Acquired seismic SIGNAL and NOISE will be carried out multiple times during the preprocessing in dealing with statics, ground rolls, converted waves, etc., as necessary. The final products will be clean, and high amplitude fidelity has been reported.
