Webb18 jan. 2024 · The total porosity (PHIT) varies in the range 0.03–0.08 and the effective porosity (PIGE) varies in the range 0.01–0.06, both from NMR logging. When paramagnetic minerals are not present in the matrix, NMR logging is very useful for measuring porosity independently from the composition of the matrix. WebbEffective porosity and micro-porosity determination can be determined from NMR T2 distribution as well from the capillary pressure curve. The cumulative distribution for …

Webb1. n. [Formation Evaluation] The set of measurements normally carried out on core plugs or whole core. These generally include porosity, grain density, horizontal permeability, fluid saturation and a lithologic description. Routine core analyses often include a core gamma log and measurements of vertical permeability. Measurements are made at room … Webb1 juni 2024 · Unlike the PHIT data, the CCA data cover only those portions of the Thamama-B zone from which cores were recovered. The wells available for permeability study (those with Thamama-B core and for which data were provided for this study) are much fewer than the wells having average wireline-log porosity (PHIT) values. nhk お母さんと一緒 キャラクター 歴代

WebbTotal porosity includes the bound water in the shale and is called PHIt. Effective porosity does not include bound water, and is called PHIe. When there is no shale, PHIe equals PHIt. Logs read total porosity. All our analysis methods correct for shale, so the answers from any method presented below will give effective porosity. Webb1 jan. 2015 · PHIt = total porosity from conventional log analysis NOTE: The service company will display a porosity derived from phase shift on the log. However, this will be … nhk カーナビ 親の車
