... and premature failure of BHA components. Early POOH leads to 24 to 48 hours of non-productive time due to BHA tripping. This puts huge economic risk on such challenging pay zones. This study exhibits detailed analysis of downhole and in-bit sensing data to increase the operational stability window enabling...

When the drill bit is situated in a sufficiently inclined part of the wellbore trajectory, the BHA equilibrium is typically not disturbed by the contact forces far from the bit, because...

... to unwanted effects. The Bottom Hole Assembly (BHA) can be deflected before the steering unit with its steering pads can counteract the deflection. This can lead to deviations from the directional plan and High Local Doglegs (HLD) when drilling in the horizontal/lateral section, which can have a negative...

This system, in control terms, is an open-loop steering system because for the same steering commands and depending on the disturbances (e.g., formation, hole gauge, bit characteristics, drilling parameters, BHA configuration, etc.), the system output in terms of surveys can vary. Also...

The contextual data required for the calculations consists of the bottom hole assembly (BHA) and survey data...

.... If a satisfactory mitigation strategy would be to change the BHA layout for the next well, then memory data will be sufficient. However, if we are to change the drilling parameters in real time, then we need detection and the appropriate telemetry in real time. We have seen that when HFTO occurs, we can see...

To solve this problem, a Compound Angle Motor was run in a conventional monobore application in the Permian Basin in New Mexico with great success. The concept uses a low degree internal tilt of the drive...

... in the lower bottomhole assembly (BHA). Typically, this vibration has a higher frequency, than the Type 1, and is independent of the tools in the upper BHA. The characteristics of this are determined by the contact points; thus, it is dominant in the curved section or where heterogeneities trigger microdoglegs...
