Abstract

An attempt to use MWD technology to create a picture (Log) of the actual window cut during a whipstock milling Job. We intend to get the log by using gamma ray imaging Log abilities to get a panaromic view of the casing cut by the whipstock and mill assemblies Currently utilizing gamma imaging capabilites to acquire Gamma Imaging logs. By examing the data returned we expect to see a change in the Gamma readings strength as the sensors pass between open hole (cut by reamer) and reading gamma counts through the casing. This data when aquired can be layed out across the log and show the length of the window and also the uniformity Another possible application of this would be to examine possible holes in casing. By using the same method described above in looking at a change in radioactive counts per second readings between casing and open hole
