Excellere Partners , a Denver-based private equity firm focused on partnering with middle-market entrepreneurs and management teams, announced it has expanded its investment portfolio through its strategic investment in Integrated Petroleum Technologies, Inc. , a leading provider of oil and natural gas engineering consulting services.

IPT will use the capital, proprietary tools and resources provided by Excellere to grow the scope and reach of its service offerings through organic growth initiatives as well as selective, strategic acquisitions.

“We elected to partner with Excellere given its proprietary value creation tools and processes that we will leverage to help accelerate our growth and solidify our position as the premier provider of outsourced oil and natural gas engineering consulting services,” said Billy Aud , chief executive officer and co-founder of IPT.
