Experience Better

Ascendience provides superior petroleum geoscience data and consultancy services, experience, excellence and energy are our core attributes.

Exploration for oil and gas is a tough game. Chasing an inventory that is without replacement means that with each success the next one becomes a little harder to find. Experience is the name we give to these hard – won lessons, from both successes and failures. We all make mistakes, but the only the real mistakes are the ones from which we learn nothing.

Experience is a cumulative expansion of understanding from the application of knowledge. Like in Geology, time is required to produce this experience, there are no shortcuts and many challenges, but the rewards are substantial.

Ascendience seeks to provide the value of experience to clients in the oil and gas and energy sectors, delivered by specialists with long careers in the business, both within E&P companies and applied research organisations. Turning wounds into wisdom, allowing our clients to profit from our experience, helping to avoid repeating the mistakes of others and pushing the odds a little more to your advantage are all key to achieving cost – effective future success.

Talk to us today and build better outcomes for tomorrow.
