Oilfield
Perforation penetration
Oil & gas; Oilfield
A measure, or indicator, of the length that a useable perforation tunnel extends beyond the casing or liner into the reservoir formation. In most cases, a high penetration is desirable to enable ...
Epithermal neutron porosity measurement
Oil & gas; Oilfield
A measurement based on the slowing down of neutrons between a source and one or more detectors that measure neutrons at the epithermal level, where their energy is above that of the surrounding ...
Pressure transient well test
Oil & gas; Oilfield
A means of assessing reservoir performance by measuring flow rates and pressures under a range of flowing conditions and then applying the data to a mathematical model. In most well tests, a limited ...
Sand consolidation
Oil & gas; Oilfield
A means of controlling the undesirable production of sand from weak sandstone formations. Sand consolidation chemically binds the grains of sand that make up the formation matrix while maintaining ...
Electromagnetic propagation measurement
Oil & gas; Oilfield
A measurement of the high frequency (about 1 GHz) dielectric properties of the formation. In a typical tool, a microwave transmitter is placed a few inches below two receivers separated by 4 cm (1. 6 ...
Density measurement
Oil & gas; Oilfield
A measurement of the bulk density of the formation, based on the reduction in gamma ray flux between a source and a detector due to Compton scattering. The gamma ray source, usually 137 Cs (cesium), ...
