An update on the Array Induction Imager Tool (AIT) in the Gulf of Thailand

The Array Induction Imager Tool (AIT) arrived in the Gulf of Thailand in June 1992, and has since performed almost 10 jobs in a large variety of conditions. The equipment has proved very reliable, and the quality of the data has been excellent. The primary purpose of running the AIT in the Gulf of Thailand wells has been to provide accurate resistivity data to minimize the error when establishing hydrocarbon reserves. Indeed, the tool is bringing about a revolution of information evaluation in thinly bedded or deeply invaded zones, where oil companies are seeing significant increases in reserves based purely on the changeover to AIT data. Important though this is, the benefits of the service are not just limited to improving the Rt value. Images of the radial resistivity profile are also giving a unique insight into the three dimensional geology surrounding the well bore, and the dynamics of filtrate movement through the more permeable sections. In every case where it has been run, the AIT provided the user with a clearer (and often more profitable) understanding of the reservoir than that obtained with conventional resistivity measurements.
