In unconventional wells, the production stream is highly volatile for the initial 90 to 120 days after first oil.
A recent study found that one third of alerts generated by automated production systems in the first 90 days in unconventional wells would have likely led to electric submersible pumping (ESP) system shutdowns if nothing was done to
resolve the underlying problems. While ESP systems provide the most economical, efficient, and flexible recovery solutions, mismanaging early-stage ESP shutdowns can defer production, lead to escalating intervention and workover costs,
and diminish long-term asset value.
If production loss is the first sign of a problem, it may be too late.
During critical phases of production, frac sand flowback, erratic flow rates, and gas slugs can negatively impact the production environment if not addressed quickly and effectively. Production loss should not be the first sign of a
problem.
If you are watching the right indicators at the right time, you can identify threatening conditions early. Changes in pump intake or discharge pressures, fluctuations in motor operating current, excessive vibrations, and temperature spikes or anomalies can lead to long-term production issues if not handled effectively.
By the time you notice a decline in production, it may be too late to reverse permanent effects to your production system. As an ESP system becomes less and less effective, you will likely rack up repair and workover expenses, ultimately risking recovery potential and the value of your asset. Resolving issues before they become threats is critical to maintaining ESP and production system health.
It pays to watch your assets around the clock.
Investing in a 24-hour surveillance service during your most critical phases of production in unconventional wells mitigates the threat of dynamic downhole conditions on production system performance and longevity.

AMBIT PLUS 24/7 production surveillance services protect your unconventional assets
AMBIT PLUS 24/7 production surveillance services combine the industry’s best production monitoring software with real-time decisioning support from Baker Hughes optimization experts. No matter the time or day, when you invest in 24/7
surveillance for your unconventional well, a Baker Hughes expert is monitoring the downhole conditions and production system operations in real time, standing by and ready to help you:
Stabilize production
Reduce operating costs
Extend ESP run life
Reduce health, safety, and environmental (HSE) risks
Resolve problems before they become critical
Based on your preferences, asset goals, and specific production system, Baker Hughes adjusts ESP systems and other equipment as needed to optimize production, minimize the impact of threatening downhole conditions, and limit HSE risks.
From the beginning, the Baker Hughes team continuously logs, processes, and assimilates data and metrics in your unconventional well to establish a unique production profile. Within hours, experts can spot anomalies. Within days, data
and metrics are being updated and evaluated, and then reintegrated into the system to build ongoing production intelligence.
After the well stabilizes, you are left with a rich baseline data set and continuous data feeds that you can use to monitor production throughout the life of the well.

An operator was experiencing significant ESP system issues, and was being forced to replace at least one ESP system per year in its onshore and offshore fields. With workover costs reaching as high as USD 4 million, the operator needed
an efficient solution for prolonging ESP run life.
The operator partnered with Baker Hughes to provide round-the-clock monitoring and real-time decisioning support with AMBIT PLUS 24/7 production surveillance services.
In one particular instance, Baker Hughes replaced a previously unmonitored ESP that had run only nine days. Through 24-hour monitoring and constant attention to detail, the team made adjustments to the ESP system as downhole conditions
warranted. That replacement ESP system has remained functional and in service for almost a year as of the publication of this document. Fourteen months after initiating surveillance services across onshore and offshore fields for the
operator, not a single ESP unit has required workover or replacement. Considering the operator was previously averaging one ESP replacement per year—and workovers in the area range from USD 1.5 million to as high as USD 4 million—Baker
Hughes has provided the operator considerable savings while sustaining and enhancing production.
