W & WT Series
Both W and WT casing are designed to Standard DCDMA W sizes, which allow nesting of casing. They are both made from parallel wall C80 tubing compatible with Q™ wireline in-hole tools. W casing is intended for single use or situations where the casing is left in the hole. The W thread is a straight thread with 4 threads per inch. This casing is universal in design and can be used in any drilling application. WT casing is engineered to surpass expectations for a casing and features quicker make-up and easier break-out characteristics than the standard W casing. The WT tapered HD thread (2.5 threads per inch) provides increased strength and works well under difficult drilling conditions and allows for repeated use.
