The Defining Series: Basic Well Log Interpretation SLB
WebDensity Log. The density log usually labelled ‘RHOB’ measures the density of the borehole and the rocks penetrated by the drill bit. The unit for density is gram per cubic centimetre. The logs (sonic and density) measurements are usually made every 6 in. down hole, but must be aligned to be ‘on-depth’ with each other. WebIn this method, it is assumed that the sonic log provides matrix porosity. The difference between neutron (or density or the combination neutron-density) and sonic porosity is … body wraps inch loss

WebJun 24, 2015 · Log analysis in shaly formations. Shales are one of the more important common constituents of rocks in log analysis. Aside from their effects on porosity and … WebTHIS PAGE Pore Volume Porosity From Sonic Log Porosity From Density Log. The second calculation step in a log analysis is to find shale corrected porosity. Pore volume is the space in a rock filled with oil, gas, or water. Total porosity includes the bound water in the shale and is called PHIt.
