About Us

It all started with a simple idea: Operators don’t like paperwork.

Back Office Support Specialists

Eddye Dreyer Financial Services began with a simple thought in mind: E&P operators are often not fully equipped to perform the complex accounting required for the management of oil and gas assets. At the same time, it can be prohibitively expensive to maintain a full-time staff of specialized bookkeepers and in-house accountants. That’s where we come in.

As a subsidiary of San Antonio-based Avisto Capital Partners, Eddye Dreyer Financial Services is a best-in-class oil and gas bookkeeping firm specializing in comprehensive bookkeeping, mineral interest management, financial consulting, and regulatory compliance services. With more than 50 experienced oil and gas bookkeepers, controllers, analysts and landsmen, we have become leaders in the oil and gas industry with specialized expertise in the latest laws, methods, and technology.

As the exclusive preferred partner of WolfePak oil and gas accounting software, we are able to offer a complete suite of solution for clients looking to outsource their bookkeeping and back office operations.
