... development plan and reserves monetization. The urgency is heightened particularly when production has declined and requirement arisen to assess the impact of CO2 concentration to the gas sales lines. Acquiring new data set in the open hole via well side-tracking may no longer be feasible in the cased hole...

Spectroscopy data not only describes the mineralogy, but also provides key measurements for fluid identification, which are thermal neutron capture cross-section (sigma) and chlorine concentration. The value of sigma and the amount of chlorine ion in the formation are both proportional...

.... For conventional oil-water system reservoirs, the simulator employs an imbibition capillary pressure curve to estimate the residual oil saturation, which is automatically calculated taking the concentration and aggregation of nanoparticles into consideration. This function was validated by successfully matching...
