... failure can be better understood, then unnecessary trips can be avoided, and non-productivity time can be reduced. Typical bottom hole assembly (BHA) performance methods include rate of penetration (ROP) and total distance drilled. From this perspective, BHAs that drill the furthest with the highest...

... When there was greater than 10% peak to peak variability in the WOB, ROP, and RPM signals over a few minute period they were graded, Unstable. These signals were graded as Stable if there was low variability or no variability. No variability occurs in RPM when the active torsional damping system...

... a solution for improving drilling performance in the lateral section. Operators often use computer-controlled "auto-driller" settings, either weight on bit (WOB) or rate of penetration (ROP) mode, to drill through lateral sections. While higher instantaneous ROP can be achieved by using WOB mode, it can...

... rop Introduction For surface data most sensors on the rig will record data at 10 – 100 data points per second. These are then processed first at the rigsite prior to being displayed and then processed once further prior to being transmitted offsite normally as 1 second data. If greater than 1...

... and equipment damages. Through drilling optimization practices, the instrumented steerable motors with proper bit selections were able to drill more than 40 ft/hr on average, doubling the rate of penetration (ROP), footage, and run length experienced in previous granite wells. This paper presents a case study...

... (2005) applied the real time surveillance of MSE to maximize the drill rates. They introduced the use of MSE as an indicator to the inefficiencies in field operations. Also, they reported a linear relationship between the ROP and WOB if there is no founder. The authors reported an increase...

...) with rate of penetration (ROP) and weight-on-bit (WOB). The term incorporating RPM and ROP represents a "sliding distance", i.e. the number of revolutions required to drill a unit distance of formation, while the WOB represents the formation hardness or contact pressure applied by the formation. This PDC...

... Abstract During the last decade, a tremendous amount of work has been published on using surface measurement of mechanical specific energy (MSE) for enhancing drilling efficiency and maximizing rate of penetration (ROP). With an increase in directional drilling, surface measurement of MSE...

... are poorly documented; therefore, the usefulness of this data diminishes through data transfer. The objective of this work is to define a meta-data framework for derived data. In this paper, we focus our efforts on one derived data channel, the rate of penetration (ROP) and identify the meta-data required...

... Abstract This paper discusses the technical challenges related to implementing a rig-site, real-time drilling advisory system and current solutions to these challenges. The system uses a data-driven response surface model based on physics-based calculations to optimize rate of penetration (ROP...

... is to optimize drilling then reducing both WOB and ROB would not be an option since that would results in decrease in rate of penetration (ROP). This puts the driller in a tough situation where both severe vibrations and low ROP could occur simultaneously during drilling operations. There is an optimum zone...
