Coil tubing fishing tools cover a wide array of applications, and can be mechanical or hydraulic. The tools are made specifically for coil tubing, and allow for pump-through capability and high loads.
Coil Tubing Services is a specialist in drilling composite/cast iron frac plugs. Wells are completed with multiple-fractured zones and the zones are isolated with drill-able plugs. Coil Tubing is used to drill these plugs to allow for maximum production rate.
An exiting development has occured in horizontal shale well appliocations. Coil Tubing is performing the entire completion. First a positive displacement motor is used for a scraper trip, then the toe is perforated using a tubing-conveyed-perforating (TCP) firing head. The subsequent isolation plugs can be set on wireline or coil tubing. After all zones have been fraced, the well is prepared for production by drilling all the frac isolation plugs using coil tubing.
In order to clean the well bore high pump rates of water and nitrogen are pumped and positive displacement motors with special bits are used. CTS’s experience shows that high annular velocities and careful execution is key to success.
CTS has developed a highly effective system where everything from the size of the coil tubing (up to 2”), to the ID of the BOP’s (up to 5 1/8”), to the size of the crane and the associated pumps help maximize the service efficiency.
