... processes for kick circulation, such as Influx Management Envelope (IME) and the MPD matrix, there is still a literature gap regarding kick management with the bit off bottom - a common scenario during tripping, reaming, mud displacement, or running liners. The identification and control of a kick...

... (1) Transfer the simulation results (e.g., pressure, temperature profiles) between Dynamic Hydraulics and Dynamic Well Control; (2) Adjust the Equivalent Circulating Density (ECD) in Dynamic Well Control to match the ECD from Dynamic Hydraulics. This can be done by modifying the mud reference...

.... It also delves into MPD's role in effective equivalent circulating density (ECD), mud weight (MW) management, and tripping strategies needed to comply with regulatory requirements. By presenting key highlights, lessons learned, and recommendations gathered from the operation, this case contributes...

... years. Operations ranging from simple kick detection, to using hydrostatically underbalanced mud and finally circulating influxes within the primary barrier limits, were performed during this period. The adaptation of MPD on floating vessels required a series of modifications to fifth and sixth...

.... The adopted solution to manage the higher-pressure requirement, minimize formation damaged, optimize operation and available resources was to use MPD to run the lower completion and execute the OHGP job. Some of the challenges to overcome included, well control considerations, reverse circulation method...

... uncertainties by taking advantage of MPD influx management techniques and multi-phase modelling. The key elements defining the well control envelope include formation strength, resolution of influx detection, realistic shut-in times, safety margin and method of influx control (circulating response with MPD vs...

... with more advanced Drift Flux Model-based simulator to explore contingencies that could threaten the process. To ensure consistency between the two models, some circulation cases were compared between the two models, showing good match. For the more advanced simulation of gas in the riser, first we...

... for the AFP that is not present due to the lack of circulation in the annular during this stage (e.g., during drillstring connections / pumps off). MPD Control System Dynamic annular pressure = Hydrostatic Pressure + AFP + SBP = (0.052 × DHMW × TVD) + AFP + SBP Where: AFP = Annular frictional...

... To remediate the situation, the drill string was tripped into the lateral and a bottoms up was circulated with no signs of a kick. Contrary to the results on the second build-up test suggesting a kick, a bottoms up circulation with no signs of gas in the drilling fluid to surface confirmed...

... diameter hole drill. Drilling hazard in Kujung formation is a loss of circulation (total loss) and followed by a kick (H2S kick), so it is anticipated to use DDV (Downhole Valve) on a 9-5 / 8 inch casing that installed at a depth of 2040 mMD and installed RBOP (Rotating Blow out Preventer). When drilling...

... Abstract Implementation of Managed Pressures Drilling (MPD) techniques provide substantial advantages for addressing difficulties in challenging wells. These benefits include not only the early influx and loss detection, but also Dynamic Influx Management. MPD provides the ability to circulate...

This is conservative and results in smaller allowable influx volumes for circulation. An iterative approach with transient...

However, Well Design A induced higher annular frictional losses (AFL), approximately 300 psi, across this section and thus greater equivalent circulating density (ECD) due to the smaller annular clearance.
