"When a company is acquired and they've used a certain type of hardware for automation control, the purchasing company basically has to re-teach their technicians how to work with the new equipment. The push for standardization remains. Too many systems even- tually will cause a problem with maintenance which ultimately adds to the overhead of these assets." Today's data volumes are also quite staggering. Operators have data coming in from real-time sources as well as data from historical sources. Many times there will also be modeling software involved as well as some other production databases. Being able to visualize all of this data so that it can be accurately analyzed and result in the best decisions is pushing some operators out of their comfort zones. As the data glut looms, the goal remains to efficiently nav- igate this expanding digital roadmap to ensure best performance from lift applications throughout the life cycle of individual wells as well as life of field. AI and the predictive challenge One of the leading-edge technology pieces to the data puzzle is the expanding use of artificial intel- ligence (AI) and automation to predict equipment longevity. Once operators can become more predic- tive and less reactive when it comes to equipment maintenance and failures, downtime will be reduced. "Ultimately operators are interested in increasing the net present value of their assets. This is done either through increasing the production from an asset or reducing their total cost of ownership. Today this is done primarily through manual processes dependent on strong technical expertise, which does not scale well to be efficient across thousands of wells," said Lawrence Camilleri, artificial lift technical director, Schlumberger. "Through digitization, automation and the Industrial Internet of Things (IIoT) we are able to deliver both production increase and reduction of total cost of ownership at scale and with repeat- ability. An example of this is the new automated ESP flowrate calculation platform from Schlumberger, which uses IIoT technology to automatically detect substandard conditions in an ESP operation (pump operating point and health), ensuring runlife is increased and unwanted shutdowns are avoided. The platform also provides real-time power optimization for ESPs during operation. Most importantly, real- time data enables high-frequency downhole flowrate measurement, which provides operators with well inflow performance relationship (IPR) during oper- ation and pressure transient analysis without the need for buildups. This is critical for optimizing well inflow by, for example, identifying opportunities for increased drawdown and stimulation. We have only touched the surface of what we can do from an auto- mation perspective in the artificial lift space, and the platform is the foundation for future enhancements." "There has been a growing trend towards proactive field management, and we are helping clients plan their lift strategy and how they manage their assets over time," said Gregg Hurst, global business director, artificial lift at Weatherford. "Our ForeSite produc- tion optimization platform is an example of how predictive analytics enable better life-of-well planning. It is an advanced analytics tool built specifically for production optimization. ForeSite collects and lever- ages data from across the asset, which allows clients to anticipate problems before they occur. The system learns from historical and real-time data and offers insights to improve current and future decisions. The platform also gives clients a standardized workflow that helps them to manage their daily activity though simple-to-use dashboards. They can even view and manage their dashboards and drive their priorities from a mobile device." Introduced in May 2017, ForeSite processes real- time sensor data from every corner of an asset to Weatherford's ForeSite platform provides well-management tools to help operators pinpoint and prioritize production issues.
