... programming (SQP) method is used. CO 2 -WAG design variables are CO 2 injection and water injection rates for each injection well at each cycle, production BHP for each production well at each WAG half-cycle, and inflow control valve (ICV) for each well at each WAG half-cycle and at each valve. We study...

... to facilitate conventional tripping since BHA would not pass through the RCD elements rubbers. Since MPD cannot be performed without the RCD rubber elements, weighted pills are deployed to uphold the required BHP before the BHA is POOH. These weighted pills save a lot of rig time during tripping as they prevent...

... adjusts the bottomhole pressure (BHP) rapidly to maintain it within the drilling margin. The cuttings concentration and blockage effects are considered in the model, allowing the automated controllers to maintain the BHP during dynamic hole cleaning operations. The developed model considers the pressure...

... (Dickens 1988 ), has two potential onshore applications. First, total elimination of gas-lift valves in horizontal wells with sub-7000 psi BHP's. This is feasible due to improvements in compressor technology created to support CNG fuel, and elevated casing pressure ratings necessitated by hydraulic...

.... In conventional cementing, the annulus is open to atmosphere so pressure at surface is zero. When there is no flow, friction pressure is also zero. The conventional way to further minimize the BHP is to reduce the hydrostatic pressure, which may risk wellbore collapse if the reduction causes BHP to fall below...

... was then extended to applications with operational parameters available, such as bottom-hole pressure (BHP). The proposed TS and NN models were applied to production data from a Barnett gas well. The historical production data was divided into two parts. The first part of the data is used to train the NN model...

..., these simulators are referenced as Simulator 1, 2, 3, 4, and 5. Abstract Underbalanced drilling (UBD) and managed pressure drilling (MPD) techniques provide the capability to precisely control bottomhole pressure (BHP). During upfront planning and engineering, as well as during the actual operation...

... where instability had previously caused drilling problems (see Figure 1 ). An important consideration in the design of a CBHP MPD system is the range of BHP which can be expected during operations. Automated MPD systems allow a BHP set-point to be selected, so that the system attempts to maintain...

... Abstract Questions arise whether bottomhole pressures (BHP), derived from their wellhead counterpart (WHP), lend themselves for transient analysis. That is because considerable heat exchange may affect the wellbore density profile, thereby making the WHP translation a non-trivial exercise...
