To address KT sensitivity to different parameters, we generated a new computer program based on a gas bubble model that applies the effect of annular frictional pressure losses, influx/mud temperature, gas compressibility factor, well trajectory and BHA. The program, however, provides different KT models...

... actions can be taken to respond to an influx while remaining within the primary well barrier. A critical evaluation of deepwater well control has been performed uncovering several limitations which can be mitigated with anASBP-MPD system. As such, this paper will describe the disadvantages of shutting...

... Abstract Overproduction of water is an inevitable risk in most mature oil fields. Operators have a high expenditure in both OPEX and CAPEX to delay the influx of water production, which is reducing both field life and economic value. With the advent of reservoir control technologies, oil...

... that resulted in severe non-productive time (NPT) and difficulty reaching well total depth (TD). Additionally, formation pressure uncertainty in the steep pressure ramp region posed additional drilling challenges due to high risk of influxes. PTTEP decided to utilize managed pressure drilling (MPD) to overcome...

Additional production (on top of allocated produced volumes) was introduced to model the corresponding efflux of gas. Manually maintaining...

... in detecting any influx or outflux during the drilling operation. An improvement to provide a better method in detecting for influx is the utilization of a flow meter to monitor the flow out from the well and the most common flow meter to be used is Coriolis mass flow meter (CMF).

... breakthrough could happen at any layer; therefore, a selective shutoff is required. A production-logging tool (PLT) was run to identify the source of the water influx, and the uppermost set of perforations was identified to be the main contributor to the water production.
