At this time, all new technology implementation, seismic data processing and interpretation projects are being operated by NPP Spetsgeofizika, founded in 2007. GDS retains its role as a petroleum geology consultancy and purveyor of innovative technologies.
Geophysical Data Systems Company is pleased to announce the release 2.3 of our IST-3MP ® system.
New 2.3 release includes first break refraction statics calculation technology, based on modified surface consistent common-source point (CSP ) and common-receiver point (CRP ) stacking technique.
The technology does not require time consuming and often erroneous fist break picking efforts during noisy shot records interpretation. Moreover, it avoids detail near-surface velocity model building process, which is also can be quite ambiguous.
The Optimized Surface Consistent Stack module generates CSP and CRP sections from gathers after linear moveout (LMO ) applied for clear first arrivals imaging. Preliminary few-points refractor velocity and offsets range analysis has to be performed on sparsely selected shot record gathers only along the line.
The optimized CSP and CRP stacking technique involves calculation and application of average time shift for each gather being stacked. This time shift relates to time delays, which are accumulated at particular moment in sliding gather along the line. Thus, source and receiver factors are automatically decoupled during the optimized stacking. First arrivals picking result obtained from stacked sections is equivalent to reduced refractor travel time curve along the line.
SCS Refractions Statics Calculation module uses first beak picks from previous step for calculation of resulting source and receiver statics, which can be exported in ASCII format from database later on.
Moreover, since the 2.2 release more than 550 fixes were introduced into the system and the following new features , modules and changes were added:
