It’s been a busy time for Delphian Ballistics recently and some great things have been going on since we won the Emerging Technology Award at the 2015 SPE Offshore Achievement Awards back in March. As well as running TriStim pilots in the US, we’re really pleased to be able to communicate some of the great results from our intensive development program to the industry at large. This program has involved API Section IV testing and CFD modelling, enabling TriStim to move swiftly from initial prototype to fully validated and commercialised perforating product that is ready to deploy.
Together with Senergy and DynaEnergetics, we’ve been engaged in a comprehensive development program that has resulted in a couple of key papers on the upside of convergent perforating systems and their potential to deliver significant productivity benefits. This is very important for us because it is the first time we’ve put this information out formally for industry scrutiny, with all results conforming to API standards. We’re excited by the fact that the great results demonstrated by this collaborative study bring huge credibility to the TriStim offering.
The TriStim Story
Mar 07 - Patent
May 10 - First field trials of prototype

Jan 15 - Gun System well certified and commercialised
Mar 15 - First field deployment
The first presentation of the results was to leading industry experts at the 2015 International Perforating Symposium in Amsterdam in May. Our man Simon Allison (Technical Director) presented them there and he described his thoughts about the importance of these results in a blog post on Penn Energy. One of the key points Simon made is that this new approach clearly demonstrates that “TriStim will ultimately add significant value through improved productivity performance”.
This sums up the whole reason why TriStim has been developed and this newly published work proves that this is a likely outcome of using TriStim to perforate.
SPE paper shows flow performance increases of up to 50%
Simon is off to present the results for a second time at another important industry event in Budapest, June 3 – 5 2015. This year’s ‘SPE European Formation Damage Conference’ is specifically focused on ‘Managing Damage for Improved Recovery’ and Simon is one of the authors of a key SPE paper on why using convergent perforating techniques is ideally suited to reducing the perforating damage that is so detrimental to productivity.
The paper “Understanding Perforation Geometry Influence on Flow Performance Using CFD” is jointly authored with members of the research team from Senergy and Dynaenergetics specifically focusses on the great work the team did on using Computation Fluid Dynamics (CFD) to model the possible benefits resulting from optimisation of the perforation geometry.
The overarching objective of perforation is creating the most effective connection to the reservoir possible.
These results clearly demonstrate that simple rethinking of the charge geometry can result in “improving flow performance by as much as 50%”.
Field trials underway
TriStim is now beginning full field trials and we’re speaking to all kinds of operators with a view to selecting candidate wells. If you’re interested in talking to us about this, we’d love to hear from you!
