Oil field operators had a need for consistent, precise and automated pumping based on real-time fluid level to the specific target level desired over time to reduce operational cost and maximize production. They have long recognized for that fluid level management while pumping is critical to an operation. If a pump runs dry or cavitates, it will be damaged. If a pump operates too fast, it can cause a well to sand up. Starting and stopping a pump was never a good idea, which is what pump off controllers do. Output potential from wells continuously changes, and before the introduction of a real-time Internet of Things (IoT) device in 2014, you had to continuously evaluate potential and then continuously redefine how to operate because of the dynamic nature of reservoirs. Fluid entry simply changes over time for a multitude of reasons.
How one water producer improved tracking and simplified reporting

The use of chemicals can be a significant operating expense for both the water and oil producers and is one of the largest uncontrolled expenses. The cost to supply chemicals and refill tanks can quickly add up to tens of thousands of dollars each month. The common practice of adding chemicals using the traditional timer method can cause waste of chemicals or costs. One platform that can control artificial lift pumps can—at the same time—control multiple chemical injection pumps in sync with the artificial lift device to maintain precise injection required based on real time output. The platform can monitor tank inventory, provide alerts for low level for restocking and confirm delivery quantity. Simultaneously, the platform monitors and reacts to 38 different definable inputs to create a real smart and safe operation. This reduces health, safety and environmental (HSE) risk and reduces operational expenses.
