IPLAB Solutions

IPLab offers its clients a range of software products for the purposes of prediction of oil and gas formations productivity parameters.  IPLab software can be tailored as Petrel plug-ins or as separate modules with the possibility of importing and exporting of data compatible with Petrel.

Currently, we offer potential clients a free trial of our modules in order to give them an opportunity of testing the IPLab software products for the first project at no cost in order to demonstrate the effectiveness of our solutions.

Modules for working with seismic cubes  

As a result, the modules working with seismic cubes allow you to get virtual cubes. Such cubes retain only the computation algorithm and appear instantly. When visualizing on a cut, only those traces that are close to the cut are computed and therefore, it results in a possibility to visualize the result very quickly, without computing the entire cube. It also makes possible to correct “on-the-fly” the calculation parameters with fast visualization, which allows for a quick selection of parameters on a section with visualization of borehole curves.
