The electrical log resistivity log as an aid in determining some reservoir characteristics.
Positive indications of oil and gas in potential reservoir sections were seen in the mud logs while drilling and as a result the Company is currently acquiring electrical logs in the well in order to define reservoir and fluid characteristics.
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.
The amount of productive sand has been significantly upgraded based on electrical logs and completion information.
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.
They will immediately run electrical logs which will confirm the presence and potential quality of hydrocarbons within the payzone.
Independent analysis of the electrical logs indicates a potentially significant oil column in the Monserrate sandstone in the intervals of 1,000 to 1,400 feet and 1,700 to 2,100 feet.
Based on the type of inconsistency, SmartPlant Electrical logs the error, alerts and logs or disallows the operation.
Subsequent open-hole electrical logs further indicated the presence of porosity and gas.
