TGS adds U.S. unconventional log databases from Petrophysical Solutions


ASKER, NORWAY – TGS announced the purchase of all U.S. onshore petrophysical log database and associated intellectual property from Petrophysical Solutions, Inc.

These petrophysical interpretations, derived from well log and core analysis relationships in approximately 1,400 wells within key unconventional basins, will be added to the current TGS data library. Customers will benefit from high-quality interpretation to aid in reducing risks, increase the probability of drilling successes and increase production by optimizing landing zones, wellbore trajectories and completion designs.

Kristian Johansen, CEO at TGS, commented, “This data acquisition supports critical points in our ongoing strategy to provide our customers with industry-leading basin and regional knowledge, prospect ranking and reservoir evaluation. Accurate parameters determined from petrophysical analysis will make our customers’ completion programs more successful. It will further strengthen TGS’ position as the leading supplier of enhanced well data onshore U.S.”

TGS brings additional value to this data by utilizing LAS Plus (LAS+) premium digital well logs as a starting point for petrophysical interpretation. LAS+ are edited, depth-corrected and composed to provide curves with maximum depth coverage, assuring that the data used in the creation of the resulting petrophysical interpretation is of the highest quality and accuracy. Furthermore, the petrophysical logs will enhance TGS’ Data & Analytics efforts, most notably ARLAS – Analytics Ready LAS, by offering models calibrated on actual rock samples to constrain machine learning algorithms while filling gaps of log curves and calculating the curve responses of missing log runs.
