Emeraude

Production logs, or PLs, are run on production or injection wells, with the goal of evaluating the well itself and/or the reservoir performance. Put simply, for producing wells, we need to determine what fluid is coming from which zone, and how much. The PL string may be a relatively simple, conventional configuration run in vertical or deviated wells that, based on the assumption the tool is centralised in the flow, measures the bulk flowrate using a calibrated spinner and then discriminates the fluid type(s) using a suite of tools usually including density, pressure and temperature applied to flow correlations in Emeraude. With the proliferation of horizontal wells in recent years the PL strings have, by necessity, become increasingly complex. The challenge is to handle segregated flow by various distributed measurements around and across the section of the pipe. Emeraude has kept pace with these developments and offers a choice of calculation schemes and visualisation options to cope with these multiple array tools from any vendor.
