Production Chemicals Optimization on Delfi for ESP pump run life

Ineffective treatment monitoring leads to premature well failures, increased workover costs, and decreased production revenue

The challenge: Ineffectively managed corrosion and scale risk can lead to wells failing prematurely. This causes producers to incur increased workover costs and experience decreased production revenue. For example, an onshore producer had a conventional manual corrosion and scale chemical treatment program but was running up more than USD 8 million in annual workover costs and more than USD 5 million in annual production losses. These costs were largely due to the suboptimal frequency inherent in manually performing corrosion and scale risk monitoring methods.

The solution: Production Chemicals Optimization of Delfi leverages edge intelligence via Agora edge AI and IoT solutions and executes physics-based models using real-time data to continuously monitor changes in well conditions and their impact on corrosion and scale risk for ultimately mitigating the occurrence of well failures.

Overtreating and undertreating leave wells vulnerable to production shutdowns

The challenge: Wells are not static systems, yet manually managed chemical treatments can remain unchanged for weeks until new data is made available. This lack of treatment alignment results in chronic overtreatment and undertreatment, neither of which mitigates corrosion and scale risk effectively, which can lead to production shutdowns and increased costs.

The solution: Production Chemicals Optimization on Delfi enables real-time optimization, including autonomous control of the chemical injection pumps. The result is chemical injection that is continuously on target, eliminating over- and undertreatment and their deleterious effects on production.

Improper production chemical treatment affects ESP performance

The challenge: Ineffective production chemical treatment is the root cause of more than 20% of ESP failures, resulting in lost production and rising workover costs. Over- and undertreatment issues primarily stem from the inability of traditional manual monitoring of changes in well conditions to provide data at sufficient frequency for continuously optimizing chemical treatments.

The solution: Production Chemicals Optimization on Delfi enables monitoring critical data such as production rates, injection rates, and scale and corrosion risk in real time so that interventions can be performed at optimal frequency.
