dGB Earth Sciences launched its new OpendTect 4.4 software that comes with three new plugins as well as significant improvements in its interpretation, editing and visualization features, said dGB.
The first new plugin is seismic net pay, which estimates net pay from seismic color inversion data by correcting average amplitude to seismic net-to-gross. Seismic net pay is used to make estimates of either net pay or net rock volume depending on the input data and calibration, said the company.
The second plugin is seismic feature enhancement (SFE), a powerful flat-spot enhancement tool that improves the signal of consistent flat events and reduces the noise of channel reflections. SFE complements common contour binning, a dGB plugin that stacks seismic traces along horizon contour lines to highlight subtle hydrocarbon-related seismic anomalies and pin-point gas-water, gas-oil and oil-water contacts. Through its ability to enhance flat spots earlier in the interpretation lifecycle, SFE can also play an important role in reducing the risk of drilling dry holes, according to gGB.
The third plugin is computer log analysis software (CLAS), an open hole log analysis package that integrates petrophysics with geophysics. CLAS, through which well log petrophysics can be performed within OpendTect rather than having to be imported, will result in improved well-to-seismic ties, the enhanced calibration of seismic attributes to reservoir properties, more robust models, and the more accurate interpretation of 3D seismic data, claimed the company.
“With operators targeting ever more geologically complex fields and looking to maximize the effectiveness of drilling and production strategies, the extra value they can squeeze out of the seismic data can make the difference between success and failure,” said Paul de Groot, President of dGB Earth Sciences.
