Production Logging

Conventional Production Logging tools provide high resolution measurements of the fluid compositions and flow rates in the downhole environment that are used to evaluate well performance. A typical production logging toolstring is comprised of multiple sensors covering a range of physical measurements in order to identify fluid types, volumes and rates of their production or injection. Each of these measurements is digitised and recorded in order to create a comprehensive profile of the wellbore environment.

Array Production Logging tools provide high resolution measurements of the fluid compositions and flow rates at targeted locations around the circumference of the wellbore that are used to provide an enhanced evaluation of well performance in segregated flow regimes. The addition of the array sensors to a production logging toolstring builds on the ability to identify fluid types, volumes and rates of production where separation of the fluid phases has occurred. Each of these measurements is digitised and recorded in order to create a comprehensive 3D profile of the wellbore environment.
