ARK CLS has expanded its operations to offer a consultancy service. Using highly experienced interpretation geoscientists, ARK CLS has been able to undertake project work for clients, to invert seismic data and interpret the resultant impedance volumes. This venture has proved to be highly successful and has resulted in subsequent software sales. Encouraged by this achievement, ARK CLS has entered into an agreement with PGL (www.pglweb.com) to provide a fuller consultancy service using our Seismic Coloured Inversion (SCI) and Seismic Spectral Blueing (SSB) software.
