REQUIRED EQUIPMENT

For cased well:

·     Service rig with an operating crew
Selected well must be shut in and prepared in the same manner as it would be for perforating.  That includes:  tubing and rod removal.

·     Wireline truck with an operating crew
For the cased well wireline crew must run collar locator to confirm depth of productive interval, chosen for stimulation and the wireline must be marked.

·     Water truck with an operating crew
To avoid stress on wireline water, solution or other fluid for depressing the well must be pumped in the well up to at least 90 feet above the interval at which SWTorpedo will be detonated. Concentration of the solution and its level in the well must be calculated based on the pressure in the formation.

For open hole well:

·     Wireline truck and Mast with an operating crew
For the cased well wireline crew must run a collar locator, for the open hole, gamma ray log must be completed to confirm depth of productive interval, chosen for stimulation and the wireline must be marked.

·     Water truck with an operating crew
To avoid stress on wireline, water, solution or other fluid for depressing the well must be pumped in the well up to at least 90 feet above the interval at which SWTorpedo will be detonated. Concentration of the solution and its level in the well must be calculated based on the pressure in the formation.

·     Final Steps
The head of the SWTorpedo must be attached to a cable head by the female adapter with 1 7/16 in. thread, electrical detonator connected to detonative cord and device connected to the head, then device is lowered to the mark on wireline, that represents desired perforation interval and torpedo must be detonated. Prepare the well for exploitation (clean up, if any), unless otherwise agreed.
