'The external interface, which was developed in collaboration with Statoil, will form a key part of the project as it allows companies to deploy proprietary technology throughout their organizations using the familiar RokDoc user interface.' 'Statoil has always been a world leader in the field of rock physics and 4D seismic, and we are very excited to be working with them to implement this leading edge technology into the RokDoc system,' says Hargrave. In addition, the project also allows Statoil to link proprietary code to RokDoc using the newly released RokDoc external interface. 'This …package is aimed at geoscientists who do not need to be familiar with RokDoc or rock physics but who need a fast, accurate, and easy-to-use way to ensure that their well data and seismic data are accurately tied.'Įlsewhere, Statoil chooses Ikon Science to implement bespoke exploration and reservoir geophysics methodology into RokDoc.Ī selection of methods published by Statoil and used in Statoil's quantitative seismic analysis will complement the existing functionality in RokDoc modules. 'The science of tying well data to seismic is recognized by everyone as a fundamental task that all interpreters need to do,' says Martyn Millwood Hargrave, CEO of Ikon. The program is available as a plug-in to Petrel. For example, unrealistic changes in interval velocity as a result of trying to stretch and squeeze data are highlighted automatically to enforce the laws of physics on system users.

The workflow-driven approach has user help and guidance. The module is workflow driven, says Ikon, and incorporates cascaded workflows enabling users to see the effects on the tie-in of changes in any part of the process including wavelet estimation, and stretch and squeeze log editing. RokDoc-Well Tie 1.0 from Ikon Science is designed to simplify the job of connecting well data and seismic data. 7,653,258, is software formulated as an algorithm and encoded in the form of a computer subroutine. 'It is almost purely isotropic, meaning that it sees the same thing irrespective of the angle it's looking from.' 'Our invention produces the least amount of inaccuracy when applying it to seismic data,' says co-inventor Mohammed N. Wang, one of the inventors, 'but, they all introduce distortion in varying degrees and adversely affect the bottom-line quality.' 'A few digital formulations describing the gradient operator exist in the scientific community and in the industry,' says geological specialist Yuchun E. According to the patent, the method gives more accurate gradients that were possible before, especially with the volume of data coming in for interpretation these days.

A move by Saudi Aramco gives it a US patent on a method to improve geoseismic data interpretation with a new algorithm that Aramco says minimizes distortion during processing.
