Abstract
A technique facilitates use of tools downhole during well operations. According to an embodiment, the technique employs a frac stack which may be coupled to a wellhead. The frac stack may include a flow control device which opens and closes a bore extending through the wellhead. A lubricator may be coupled to the frac stack. The lubricator includes a tool trap which opens and closes to facilitate controlled movement of a tool along the bore. A tool position detection system is used to detect a position of the tool in the tool trap to ensure, for example, removal of the tool from the frac stack before closure of the flow control device.
