Meet the Team

We recognise that people buy from people. You want to know that the key individuals in any company are people you can trust. People with experience and a track record of delivery. People who are as immersed in your industry as you are, and who can understand what you need. While our delivery is in the cloud, that doesn’t mean we want to keep you at arms length, and every one of our team is available to respond to whatever queries you have.

    Midenergy Operating: Simplifying Allocation

“Technical innovation is something we believe in strongly and immediately saw the benefit in using EnergySys. The time to implement and have the system up and running was a matter of weeks, not months. It was something no other supplier could offer.”
ZaZa Energy, USA
"I like the automatic data uploads (from PI) and processes (monthly reports). Both of these aspects save time and reduce error. Since implementing EnergySys, I have found that there is more organisation, an auditable process and a move away from spreadsheets which improves accuracy."
Ithaca Energy, UK
"We've been working with EnergySys for 15 years now…and I think that's the important thing, to have that personal touch'  
Apache logotype
"TAQA needed their production allocation solution to work in conjunction with OFM for in depth reporting. The EnergySys platform easily integrates with third party software.”
TAQA Bratani, UK
"What we've just done and how quickly we've done it, would not have been possible with any other tool"
TAQA Bratani, UK
"I like the idea of building something web-based that I or any of my employees can operate. It's not like a big heavy software system that sits on a server and requires a lot of attention or maintenance" Norbert Csaszar, President
Midenergy Operating, Texas USA
