Well Logging
Well logging technology is now used in all the phases of the E&P process from the drilling of the first wild cut well in a field up to the abandonment of the last productive level in the same field.
Due to the exploitation of a large number of physical principles, well logs can now measure a large number of physical properties of the geological formation (and the sorrounding environment) intersected by a well and both in open and cased hole conditions.
The methods of measurements (and the parameters included) have now become so numerous that a log analyst would need a specialized knowledge of physics, chemistry, geology, petroleum engineering, electrical engineering, mathematics and many sub branches of these, in order to follow developments in instrumentation.
Well logging applications:
- Petrophysics;
- Formation Evaluation;
- Reservoir Characterization;
- Reservoir Management & Production Optimization;
- Geology & Geomechanics;
- Geosteering;
- Others.
Main components of the well logging technique are:
- Sensors,
- (Digital) Data handling and interpretation models,
- Computer technology,
- Education & Training,
To achieve the challenging objectives of the well logging technology and since the key issue is the efficient and effective use of all available techniques, a strong collaboration with major Service Providers is necessary.
This collaboration need to be effective in all the steps of the Formation Evaluation process:
- tool/sensors/techniques design (fit for purpose R&D);
- planning;
- acquisition and QC;
- post-processing;
- interpretation;
- integration.
The NoDoC Model describes the cost of various well logging techniques. For this purpose NoDoC divides the assembly into different parts for selscting methods, techniques , equipment and hence man power required for the well logging. At the end the assembly estimate the cost for each pahse of the logging process separately.
