2024

2024 12d 12/18/2024 ui l2 issues fixed an issue where selecting a historical gas lift issue would show content for latest daily production instead of the issue date l2 gas lift enhanced functionality to allow users to click on an issue in the traverse chart and be redirected to the corresponding date on the l2 issues page if multiple issues exist for that date, the user will be routed to the first issue well performance dashboard fixed an issue where gas lift export recommendations incorrectly displayed the recommendation in the opportunity column now both the opportunity and recommendation are exported l2 issues added functionality to show l2 esp content on an upthrust or downthrust anomaly at the date of the issue compute fixed an issue where the sankey diagram was not showing wells which have no opportunities fixed an edge case where sufficiently bad surveys were causing an unexpected failure in well model journal creation causing the well to fail to generate a data quality report data platform change the “absolutepressure” uom default settings value from psia to psig to ensure consistency between pressure measures on the ui for tenants and users using the default settings 2024
