The porosity base on density log measurement is calculated from mass balance relation:
The calculated local variables of density log data were applied to predicting the calorific value of Sysola oil shale.
Data analysis indicates that density log value are too high, warranting a calibration through recalculation corroborated by the core data.
Based on Gamma Ray (GR), Resistivity log (LLD), Density log (RhoB) and self-potential log (SP) along with published literature data different, environments of deposition are assigned to the Cambrian and Lower Permian rock units.
Therefore, rock mechanical properties can be estimated using dipole sonic log providing P-wave and S-wave velocity information and density log.
Schmoker [16] and Hester [17] used the density log method to determine organic matter content in source rock.
Total Organic Carbon (TOC) and Total Organic Matter (TOM) determined from the density log correlates with laboratory values obtained by Petters et.
Later to confirm our calculated DT log, a synthetic seismogram is generated using calculated DT log and density log (RHOB).
The TOC and TOM values calculated from density log indicate that the TOC of Gongila shale exceeds the kerogen threshold of 0.
2 well was drilled to a depth of 12,550 feet and encountered 210 net feet of sand with greater than 15% density log porosity in four Lower Vicksburg sand intervals.
To interpret petrophysical properties, different logs were used which include gamma ray log, neutron log, density log, long latero log, spontaneous potential and sonic log.
In the subsurface, the gamma ray and combined neutron- density logs extrapolated the lithology ofthe Chorgali Formation.
