Cased Hole and Production Log Evaluation

4.5 Average client rating (based on 60 attendee reviews)

This course covers a wide range of topics that cover Open Hole formation evaluation and cased hole production logging and reservoir monitoring. The course covers the following topics:

General: This covers tool conveyance in Open hole and in cased hole. It also covers well completion and depth control.

Open hole: A general overview of open hole logging to obtain porosity, lithology and water saturation. Open hole log data and essential as an input into cased hole log evaluation.

Reservoir monitoring: This cover Pulsed Neutron Log applications to obtain water saturations using Neutron Capture mode and Carbon/Oxygen mode. Resistivity measurements behind the casing is also presented for conductive casings (steel) and non-conductive casings (plastic, fibre-glass). Finally cased hole Wireline formation testing is presented that is used to obtain pressure/permeability/sampling behind the casing.

Production logging is covered to obtain oi/gas/water production at any selected interval in vertical/horizontal/deviated wells.

Well integrity will cover leak detection using temperature/noise/Oxygen activation logging. Cement evaluation will also be covered in details using Ultrasonic and acoustic logging. Permanent temperature fibre glass sensors will also be presented. Finally corrosion theory and measurements will be presented indetails outlining the different tools used.
