... point with the formation was Type 2. Thus far, although there have been many papers documenting detection of HFTO, documented cases of its mitigation have been far fewer. Detection To mitigate HFTO, we need to characterize its occurrence and have knowledge of its triggers and duration. We...

... risk, minimise production loss, and ensure all well objectives are achieved. The execution strategy includes simple jetting and rotating BHA designs for 3D-profile trajectories, remote real-time monitoring including 24/7 survey QA/QC and validation, and mitigation through a decision-making matrix...

... of stick/slip mitigation is through control of the top drive. In existing applications, the vibrational wave at a fundamental frequency is absorbed by tuning a proportional-integral (PI) controller. Stick/slip-induced vibrations do not exist at a single frequency, and the simple PI controller cannot...

... vibration mitigation in drillstrings. The new feedback controller is designed such that the closed-loop system is stable with adequate gain margin for robustness. As a proof of concept, a 35 degree of freedom lumped mass drill string laboratory testbed was developed that utilizes precision inertial masses...

... Abstract A wide variety of annular pressure buildup (APB) mitigation techniques have been deployed in the past two decades. In the early 2000s, BP focused efforts on the development and implementation of rupture disks, nitrified foam spacers, syntactic foam modules and vacuum insulated tubing...

This paper will examine the pros and cons of each system and their respective abilities to mitigate hazards and optimize drilling efficiency. Conventional MPD...
