Producing Operations are developing advanced tools in response to the challenge of maximizing oil recovery and minimizing operational costs. Oil and water volumes from producing wells are measured by well gauge systems. Poor gauge system performance can mask true well output, at the expense of well optimization decisions.

In Texaco's Bakersfield Division, two statistical analysis techniques, Process Capability Index (PCI) and Confidence, are being used to improve gauge systems so that true well performance can be analyzed.
