Tall Oak Midstream Using Hosted, Subscription-Based Implementation of ESI’s Accounting and Management System for Midstream Gas Gathering and Processing

HOUSTON – December 16, 2014 – Tall Oak Midstream, LLC  (“Tall Oak”) has officially “gone live” with new GasStream™ software from Energy Solutions International (“ESI”). Based in Edmond, Oklahoma, Tall Oak is one of the fastest growing midstream companies in the Midcontinent and serves multiple producers across Oklahoma. Following a successful 12-week pilot, Tall Oak entered into a hosted, subscription-based agreement with ESI for full commercial utilization of the GasStream™ software for all of its natural gas gathering and processing assets, effective December 1, 2014. Developed for midstream companies using state-of- the-art technology, GasStream™ software is ECI’s  advanced transaction and volumetric accounting system.

“Tall Oak Midstream is using GasStream™ software to manage all of our volumetric and transaction accounting,” said Tall Oak’s Chief Financial Officer, Max Myers. “Because we’re growing at a rapid pace, we need a system that can do more than support our current needs. We need a flexible system that has the capacity to grow with us. Our internal accounting team looked at a number of commercial software applications before we decided to pilot ESI’s GasStream™ software. This trial was extremely helpful. It didn’t take very long to see that the GasStream™ solution is the right one for us and that ESI is a great company that values customer service as much as we do.”

“Initially we were very interested in the fact that ESI offers a hosted, cloud-based solution that our team can access from our office computers and from phones or tablets out in the field and at home,” said Adam Klunzinger, Tall Oak’s manager of accounting and finance. “The additional flexibility ESI offers by enabling us to subscribe on a monthly basis was also very attractive to us. Then, as our team began using the software, we quickly discovered that GasStream™ is very powerful, intuitive and easy to use. The ESI team did a great job of getting us up and running in a little over two weeks, which is very fast for complex systems of this kind. ESI continued to work closely with our accounting group through the duration of the pilot to ensure the system met all of our requirements. Our team is thrilled with the results. Tall Oak Midstream could not have found a better system or a better vendor for our gas gathering and processing accounting needs.”

“We are very pleased that Tall Oak Midstream has selected Energy Solutions International and the GasStream™ software to meet their midstream volumetric and transaction accounting needs,” said Eric Johnson, vice president for gas management systems at ESI.

“Tall Oak Midstream is a young, innovative, rapidly growing company with a seasoned team of executives driving its success,” Johnson continued. “This is precisely the kind of company we were thinking about when we developed the GasStream™ software. The opportunity to work closely with the team at Tall Oak Midstream to demonstrate that a hosted, subscription-based application of the

GasStream™ software will do everything they need it to do, both now and in the future, has been tremendous. We look forward to continuing to deliver the innovative solutions Tall Oak Midstream needs to support its growth.”

The GasStream™ software is a transaction and volumetric accounting system for midstream natural gas gathering and processing. GasStream™ tracks and manages contracts, nominations and deliveries as well as ownership of the raw wet gas from the natural gas wellhead through the processing plant along with the dry gas and related products produced there. GasStream™ was developed using state-of-the-art .NET and HTML 5 technology, making it powerful, secure and mobile friendly. The product can be implemented either as a traditional installation at the customer’s site, or can be hosted and delivered via cloud computing through  a monthly subscription service provided by DYONYX, ESI’s preferred global hosting partner.
