Production Loss & Deferment Management
These data flows and calculations quantify deferred production and production losses based on previous vs. actual performance. Quickly discover the most common reasons for downtime on all assets and filter to downtime reasons.
Workover Candidate Selection
Regularly, the best workover candidates with the highest potential production gain have been overlooked because they are not always obvious at first sight. Suboptimal workover investments lead to missed production targets and increased lifting costs.
Synthetic Log Generation
Using the Self-Organizing Maps (SOMs) approach, wells are subdivided into clusters. A minimum set of well logs is identified for the application of this approach. Any other, not measured well logs, are predicted by using similarities to other wells and their logs within established clusters.

Rate Estimation & Allocation
PetroVisor identifies wells where remedial action (e.g. pump adjustment) could prevent a future shut-in, or where deteriorating production can be restored (water or gas shutoff, casing leaks, scale buildup, …). The wells are ranked according to how much (risked) production is being lost or at risk.

Reservoir Property Prediction
This package calculates production rates based on field available data, e.g. by using virtual flow meters (physical models, ML models), or by artificial lift data (Dynamometer card data, ESP data), etc.

Marginal Well Identification
The package can identify underperforming wells using various key performance indicators such as heterogeneity indices, production thresholds or compares actual production with monthly targets.

Gas Breakthrough Production
Detects gas breakthrough based on Chan diagnostics. The developed solution utilizes user defined threshold from GOR values, the trend and its derivative of GOR and assign different probabilities to detect gas breakthrough based on the values of the aforementioned input elements.

Reactivation and Shut In/ Underperformance Advisory
The Production Optimization App recommends wells where workover/intervention actions, rig or rigless, (e.g. stimulation, N2 kick-off, water control, etc.) may activate currently shut-in wells which are economically profitable. The wells are ranked based on technical and financial metrics, including their historical issues, production, and reservoir potential.

Water Coning and Channeling Identification
The solution automatically detects water coning or channeling risks based on Chan diagnostics. The logic applies automated coning and channeling probabilities detection using the water-oil ratio, including the raw and derivative values.
Performance and Pay Zone Prediction based on Well Log
Integration of production performance and well log data. Feature extraction and Machine Learning techniques for identifying correlation between lithofacies and production performance.

Sand Management
The solution can integrate real time data from both intrusive sensors (used for monitoring the caused damage, i.e. erosion) and acoustic sensors (sand rate) showing rapid changes during sand trial tests.

Gas Lift Optimization
Applies gas lift monitoring with stability assessment - two stability criteria (inflow response and pressure-depletion response) are applied for examining stability problems and optimizing ongoing gas lift operations. The solution package also calculates theoretical injection rate on volumetric gas throughput of an orifice or choke, which can be used to detect multi-injection issues.
