f MPLT Flow Zone Summary 1997-2009 for Karachaganak Field, Kazakhstan

Memory production logging tools (MPLT) have been run in the Karachaganak Field since 1997. Measurements such as spinner, temperature, density and pressure are run (on wireline or slick-line) to identify zones of hydrocarbons entering the wellbore. Flow rates are derived from these measurements across individual flow intervals and can be converted to % contribution of the total accumulated flow. Therefore, adding up all the % contributions for each flow zone from a MPLT Run will total 100%.
