The electrical log
resistivity log as an aid in determining some reservoir characteristics.
According to the geophysical properties of the rocks, the logs are always classified as follows: electrical logs
, porosity logs, lithology logs, and miscellaneous logs.
The company said that, based on mudlog shows, electrical logs
and petrophysical analysis, a total potential net pay interval of 101 feet (31m) minimum case has been identified.
Pre-1958 electrical logs
comprise as much as 40% of the well-log data in oil and gas company files.
"Preliminary evaluations of electrical logs
indicate 20 meters oil pay in the well," DNO said.
These petro physical properties are determined by, Electrical logs
, Natural Gamma Ray Log, Gamma Ray Density Log and Sonic Log.
Norwegian oil company DNO ASA said on Thursday (31 March) that evaluation of electrical logs
in Nabrajah #5 in Yemen indicates the presence of hydrocarbons in a 42-metre gross interval in the Kohlan Formation overlaying the basement.
indicate that the presence of hydrocarbons is insufficient to carry out any well tests, and the well has been plugged and abandoned," DNO said.
