... Abstract Traditionally, well control systems have been entirely reliant on a single human reliably and accurately detecting an influx and shutting-in the well.  The human condition means the driller can be distracted, or unexpectedly influenced by extraneous factors. Over-reliance...

... the surface, leading to a major well control risk. Integrated Pressure Activated Valve (PAV) with Autonomous Inflow Control Valve (AICV) offers a unique solution to manage well control risks, allowing safe deployment of lower completion in such challengeable situations. The PAV module is mounted in series...

... Automating a well control process is a much simpler task than managing pressure during an MPD application. Some MPD systems today are managing bottom hole pressure within a 50-psi window. Several of the transient effects that must be calculated and managed during MPD are not in play during a well...

... an actual well control event, and their impact on the interpretation of the well behavior. Moreover, this paper provides useful insights on the additional capabilities offered by the usage of the Managed Pressure Drilling (MPD) technology in managing a gas kick. A peculiar well control situation occurred...

... the first optimization iteration is used to construct the snapshot matrix. The results demonstrate how refining the control approximation with more decision variables per well lead to better NPV values, but with a higher computational cost. The best NPV was achieved using the highest refining level...

... Abstract Managed Pressure Drilling (MPD) dynamic influx control techniques offer substantial advantages over conventional well control, including reduced influx size, and the ability to control and circulate an allowable influx without requiring conventional methods. With careful planning...

... Abstract This paper presents a case where Managed Pressure Drilling (MPD) was used to drill a challenging exploration well through a pore pressure ramp and to address a well control event in conjunction with conventional methods when an influx was encountered The MPD system was used to drill...

... Abstract Well Integrity issues associated with barrier degradation due to corrosion could significantly impact on production results in mature fields. Sometimes those issues may lead to the severe well control incidents during production phase affecting on the performance of the facilities...

... gradient, resulting in planning for up to six casing strings. To respond to this challenge, standard engineering practices were augmented with additional monitoring and predictive modelling solutions to improve well control and to predict and explain complex well behaviour and mitigate the associated...

... and field-trialed successfully that eliminates the need for an inner string during installation, allowing circulation through the liner while running in hole as well as hydraulic setting of the openhole packers before pulling out of hole with the workstring. This also provides an improved well control...

... the downhole pump. Mechanical well service uses well service rig or pulling unit rig, mainly to pull and to run the tubing. One of main component of the rig is well control equipment system. The complete package of the well control equipment system is about 30% of the rig service package. The equipment may...

... Abstract This paper presents the success story of an innovative milling operation on a stuck-closed tubing master valve performed with electric line technologies. This field application has resulted in restoration of well accessibility, enabled well control, and saved costs related to rig...

... Abstract The Oil and Gas (O&G) industry is, by its nature, a high risk industry and poses risks to both staff and workers if appropriate controls are not in place. Failures in implementation of well control safe operating systems have resulted in incidents of varying nature, fires, loss...

... allows for single phase and multiphase modelling and thus also well control modelling. The model has been utilized in planning, training and also during real time operations for decision support. A sophisticated user interface including 3D Visualization of the well has been developed. This has been...

This situation is often the case for some well designs commonly used to re-enter oil producer wells in Saudi Arabia. Under these circumstances, the main well control strategy is to maintain enough of a mud cap to prevent...
