- Infield faults contributed to a narrow equivalent circulating density (ECD) window, associated loss of circulation and well control difficulties
- Wide mud weight swings due to gas influx control resulted in a heterogenous fluid column with an unstable and unpredictable mud weight
- Excessive days were spent trying to manage the well control, and losses of mud contributed to excessive costs and non productive time (NPT)
Solution: MPD techniques by @balance Services in combination with modeling of the ECDs using VIRTUAL HYDRAULICS allowed for better well control.
- By using the M-I SWACO LOW PRESSURE AUTOCHOKE CONSOLE (LPAC) MPD equipment and @balance Services techniques, constant wellbore pressure was maintained, preventing an influx of undesirable quantities of formation gas
- VIRTUAL HYDRAULICS modeling allowed for estimated ECDs, which enabled proper kill weight mud pills to be calculated and spotted for well control
