Multifocusing processing 2d / 3d

Substrata and Geomage provides most accurate seismic data processing services with its proprietary MultiFocusing Imaging technology. Geomage MultiFocusing© imaging used successfully all across the globe for wide spectrum of different geological/geophysical conditions/problems:

  • Data interpolation and regularization
  • Structural seismic imaging
  • Unconventional seismic
  • Sparse/low-fold seismic
  • Wide/Full-azimuth seismic

MultiFocusing data enhancement

  • In many situations, increasing SNR of pre-stack seismic traces is requested. Typi­cal examples are velocity model-building and pre-stack imaging. Wavefield parameters estimated by the Common Offset Multi-Focusing (COMF) method can be used for pre-stack data enhancement, interpolation and regularization.
  • In this case application locally stacks pre-stack traces related to near offset/azimuth values along estimated COMF kinematics parameters. The fold and position of traces in the produced gathers can be defined by original geometry or regularized according to virtual acquisition pattern.
  • The result of the summation is assigned to the same surface location, offset, and source-receiver coordinates. Repeating this procedure for all desired points generates a new trace gathers that is called the COMF enhanced gather.

Field Development & Prospectivity Studies

Oil and gas exploration and exploitation require a large amount of economic resources in onshore and offshore environments, albeit offshore environment requires more resources than onshore. Field Development and Prospectivity Studies have the main objective of maximizing the revenue from a given investment. Scenarios with the greatest median (P50), Net Present Value(NPV) and lowest spread between P10 and P90 NPV are usually selected. Economical evaluation is complicated because there are so many variables to be considered in the study and decision making process. We understand that in the exploitation of a hydrocarbon field, the process of identifying the concepts technically feasible and associated to the best economical performance is a critical success factor. In today’s Exploration and Production identifying viable assets has become very challenging hence the need for very experienced teams and advanced technologies available in the industry to make informed economically viable decisions. Our team in conjunction with our technical partners, provides this service efficiently and cost effectively to our esteemed clients.
