The Expro Water Investigation Tool (WIT) combines a downhole video camera with several logging sensors to give a tool that is designed to pinpoint hydrocarbon and water entry points in wells where water cuts are in excess of 50%.
In such high water cut wells, traditional electronic sensors used for determining water hold up and phase composition are less than accurate. Even the recent array tools have limitations based on their sensor, technology and materials.
By using a camera as the primary sensor it is very easy to see where hydrocarbon is entering a water phase while the temperature/pressure/spinner tools are used to identify any water ingress points. A gamma ray and casing collar locator are also included for correlation purposes.
It is especially suited for deviated wells where segregated flow makes fluid ingress and identification more challenging.
