There are four main reasons for lost production.
1. AL failures resulting in the well being unable to produce. This event is typically recognized quickly.
2. A problem with the AL system that has occurred since the start of the installation. Examples of this are ESPs with broken shaft, blocked intake or wrong rotation or gaslift with an unloading valve that never closes. These issues are impossible to spot using realtime data and production information as there is no change.
3. A problem with the AL system that results in the lift doing less than it should. This may be a sudden change such as a twisted shaft (easy to spot) or gradual changes such as wear or deposition in a pump.
Would you like to have the software tools to be firmly back in charge of managing your artificial lift systems?
Some say there’s an art to optimizing artificial lift. In our experience, it is a science that depends on accurate and appropriate data. While operators and suppliers produce plenty of figures, they’re often not the ones that are relevant to driving artificial lift improvement. And if the numbers do exist, they are so scattered across multiple systems and spreadsheets, they are unusable. Bringing it all together – even assuming you’re recording what you actually need – can be a nightmare.
After more than a decade of grappling with disparate data on many well types, we identified that there were opportunities to help our clients, by providing a systematic approach to what data they record – and more importantly, why they record it.
The result is Pump Checker, a one-stop shop for artificial lift management.
Pump Checker enables viewing of real-time AL operating data, production information, ESP diagnosis and runlife tracking all in one intuitive system. As a client recently said, “it puts all the information we need in one place.”
High-level dashboards and management by exception processes combined with daily and weekly exception reports point engineers and management directly to their problems and opportunities – saving time and allowing engineers to work on the wells that will give greatest gains.
Pump Checker automates the process of identifying such wells with problems and presents the problems and opportunities through management by exception reports that you can see within the application or have them delivered on a daily or weekly basis to your inbox.

ESP and Gaslift Diagnosis
Pump Checker is the ideal tool to optimize ESP or gaslift performance and diagnose reservoir inflow performance for future system design.
It validates Well Test data (giving you a double check on the figures), quantifies lost production and determines your bottom hole flowing pressure. As an operator, by having your own tool and process to validate ESP and gaslift performance, you are firmly back in charge of monitoring ESP-produced wells. It tells you if the equipment you’re using is performing and whether you’re getting all of your production.
Pump Checker means you can challenge “well conditions” as being the cause of repetitive failures in Root Cause Failure Analysis (RCFA) reports from your ESP supplier, by forcing failure categorization through a structured process that drives corrective actions, improving performance and ensuring fit-for-purpose equipment in your wells.
"The most important learning is that we are way deficient in our ESP analysis. We now have any action items that we need to work on to improve production. We have been focusing on the wrong parameters for ESP analysis."
