What systems can be used to run TriStim?
The TriStim gun system can be deployed in the wellbore using all of the methods commonly used for conventional perforating: electric wireline, jointed tubing, coiled tubing or slick line.
What sizes of gun are available?
With standard perforation gun sizes of 2⅞”, 3⅛” and 4½”, the TriStim product range is designed to address the vast majority of customer requirements.
Is any extra training needed?
No extra preparation work or training is required by customer staff, compared with a conventional perforating programme.
Because the guns are fired in a conventional manner, there are no additional issues with explosive licenses. This also means deployment does not require substantial new work or training for the crew or platform management.
Does the TriStim gun system use non-standard components?
The TriStim systems have been designed and optimised for the best possible perforation performance. The TriStim system utilises components that are both field proven and recognised as being standard ballistics componentry throughout. This includes all aspects of the gun systems, i.e. firing head, detonation cord, shaped charges, gun casing and charge carrier. All of the currently available TriStim gun systems have been qualified through the recommended API collapse and survival testing requirements.
What are the current deployments options for TriStim?
TriStim has been designed specifically around cased hole and through tubing applications. The TriStim system is manufactured and assembled by partners bringing direct access to Hollow Carrier Gun System expertise and technology. TriStim therefore is able to be designed, supplied and run as systems for wireline, tubing-conveyed or coiled tubing operations to an exceptionally high quality standard.
How do Delphian support the evaluation / design of the gun performance for my reservoir?
All pre-job engineering design and performance evaluation is conducted through Delphian’s ProBallistics™ applications engineering process. In doing so Delphian conduct a rigorous application engineering programme, looking specifically at the uncertainties / variability of the reservoir data often used in the design and performance prediction modelling processes. Using our process and design tools we have created the ability to evaluate candidates at the appropriate level of detail, firstly to assess the suitability of the TriStim application, before moving into a more detailed design phase where a performance envelope can be generated for the well / wells in question.
