APS Near/Far Corrected Limestone Porosity (FPLC) |
This is an acronym for a well log used in the oil and gas industry. You might have encountered this acronym FPLC in your log evaluation software or any (ASCII) log files provided by the logging company. The official name for this log is 'APS Near/Far Corrected Limestone Porosity'. This log is not used too often in the industry. This log helps to evaluate the porosity derived from a neutron logging measurement, assuming that the rock matrix material is calcite. So basically this is a measure of the porosity as measured with an neutron logging device. In general this log thus reflects units of the apparent porosity. This is a measure of the initial estimate of porosity, normally from logs, not corrected for the (often large) effects of clays, gas, etc. Such estimates should only be used for qualitative interpretation of clean, gas-free intervals. In general this is a measurement of the volume fraction. In other words, the ratio of the volumes occupied by two components, or by one component to the total volume of the system.This log usually has the unit 'Porosity'. This is the pore volume per unit gross volume. Porosity is determined from measurements on cores or interpreted from logs. Data for this log is produced by a tool that uses a neutron logging technique and can be used to investigate the porosity of the formation. Similar logs are listed below: - Neutron Porosity Sandstone, Borehole Corrected, Transmitted (NPSX)
- Thermal Neutron Porosity (TNPA)
- APS High Resolution Near/Far Corrected Limestone Porosity (HFLC)
- APS Near/Array Corrected Limestone Porosity (APLC)
- Neutron Porosity Sandstone, Borehole Corrected, Memory (NPSM)
- Smoothed Neutron Porosity (LS, SS, or DOL) With Subsequent Formation Salinity, Temperature, and Pressure Corrections Applied (NUCP)
- Smoothed CNP (Limestone Matrix-Caliper Corrected) (SPLC)
- APS High Resolution Near/Array Corrected Sandstone Porosity (HASC)
- APS High Resolution Near/Array Corrected Dolomite Porosity (HADC)
- Neutron Porosity Dolomite, Borehole Corrected, Transmitted (NPDX)
