OPES International

What OPES International does

OPES International is a privately held petroleum engineering consulting company headquartered in Perth, Australia. Founded in 1990, the firm has operated continuously in the Western Australian upstream oil and gas services market for more than three decades, positioning it as a long-tenured specialist in a regionally concentrated industry cluster. Its scale, indicated by a headcount band of 11–50 employees, classifies it as a small boutique consultancy rather than a large engineering services platform.

The company's publicly available information is extremely limited. The corporate website at opes.com.au returned only a generic loading/verification page during data capture, and the aggregated source records contain no documented products, service lines, technology stack, proprietary methodologies, certifications, partnerships, or named clients. As a result, the precise functional scope of its consulting engagements — whether reservoir engineering, production optimization, reserves evaluation, drilling advisory, or broader upstream technical services — cannot be confirmed from the input data.

The business model is consistent with a fee-for-service professional consulting structure serving upstream oil and gas operators and related stakeholders in the Perth basin and broader Australian market, but pricing models, contract structures, and customer segmentation are not disclosed in the available sources. No funding history, M&A activity, leadership changes, or strategic transactions are documented, and the firm has no public ticker or disclosed parent entity.
