Neural Net Training Process Quantico’s software models use proprietary weightings of several input measurements that vary from basin to basin Quantico Energy Solutions LLCConfidential6 Model Weight Input Measurement Shale Basin D ATA I NTAKE Receive and review data sets for common inputs across service companies. Ensure consistent quality of such datasets. T RAINING Demonstrate ability to predict DTS, DTC and RHOB on training wells. Review predictions against measured horizontal logs. B LIND T EST Predict DTS, DTC and RHOB on near-by wells not used in training the models. Review predictions against measured horizontal logs. E RROR R EDUCTION Systematically reduce mean squared errors relative to measured logs

Selected aspects of NN training Quantico Energy Solutions LLCConfidential7  Simulations of well logs used in training should exhibit reasonable accuracy. Otherwise, we know we are missing key input parameter or physics does not work.  QES internal software has flags for where simulations models may be used. Determined by max/mins of training logs – not by geography/distance  We evaluate different combinations of input parameters. In Eagleford model, ~50 cases analyzed, with 30+ sub-models built for each case. >24 hrs to run each model  In multiple blind tests, high fidelity overlays with: Conventional logs from Schlumberger (Thrubit) and Weatherford Halliburton pulsed neutron generated density logs (derived from two completely independent development efforts and training sets)  In the 5% of instances where the overlays did not match, the conventional logs were shown to be suspect in most of those cases
