Legacy system replacement for a major Nigerian offshore operator.
One of Africa’s fastest-growing energy producers operates six production platforms with nearly 200 well production strings off the coast of West Africa. Pipeline allocation runs across more than 20 transfer points, shared with a number of partners.
When they acquired an onshore asset and inherited a legacy system that didn’t fit their standards, they replaced it with EnergySys.
The operation.
This operator has interests in offshore fields and deep-water basins off the coast of West Africa. Their portfolio spans both offshore and onshore assets, with a commercial layer that involves multiple partners across more than 20 pipeline allocation transfer points.
Managing production data accurately across that structure and reporting it transparently to partners requires a system that can handle operational complexity and commercial allocation without compromise.
The challenge: an acquired asset, an inherited system, and a short timeline
Following the purchase of an onshore asset, the operator identified that the legacy system that came with it was not in line with their company standards. A replacement was needed, and it needed to be delivered quickly.
The solution.
The operator selected EnergySys, implemented through a joint delivery between EnergySys and a local partner.
The speed of implementation was a deciding factor. EnergySys’s low-code, configurable architecture meant the team could deploy a fully functional production data management system without the lead times associated with a traditional development-heavy implementation.
The bottom line.
A complex offshore portfolio, an acquired asset with an unsuitable legacy system, and a short delivery window. EnergySys gave this operator a replacement system that matched the scale and complexity of their operation without the implementation overhead.
