apparatus configured to evaluate a training fluid and method of evaluating a training fluid

摘要

salinity of salt water by speed of sound. the present invention relates to temperature and pressure measurements that are made borehole are used to predict a compression wave speed for pure water under borehole conditions. the predicted velocity and a measured compression velocity of a formation brine are used in a non-iterative method to estimate a value of formation brine salinity that is between 0 and 1.
