Diagnosing Condition of Whipstock
Client Case Story
A Middle East operator attemped to add a section to a multi-lateral well. However, they encountered problems setting the whipstock and milling the casing window, and attempts to first fish and then to mill the whipstock were unsuccessful. Several weeks later, the operation was suspended.
The VR90 downhole X-ray diagnostic service was used to determine the condition and position of the whipstock.
The orientation of the whipstock was immediately obtained. Images acquired by the VR90 tool also revealed that a large portion of the whipstock had been milled off, including the latching point. It was therefore concluded that the whipstock was unfishable.
The client was able to obtain clear information about the condition of their whipstock, thanks to the VR90 tool's ability to acquire images even in opaque well fluids. The results lead the client to make a quick, informed decision about how to proceed, saving them further loss of productive time and money.
