... is intentionally designed to be lower than the pressure of the formation being drilled. This results in higher rate of penetration (ROP), prevents fluid losses and related causes of formation damage. This paper presents the design and development of a UBD simulator which is computer software that simulates...

..., the rate of penetration (ROP) typically decreases. It is therefore important to optimize Bottom Hole Assembly (BHA) performance in conjunction with PDC drill bits. This paper demonstrates how Motor performance data coupled with an ROP model can predict the optimal weight on bit (WOB) required to achieve...

... Abstract During the past two years a drilling simulator has been applied in a pre-simulated and follow-up mode on dozens of well in Western Canada. Using a commercially available rate of penetration (ROP) drilling simulator, the drilling learning curve of mature fields in Western Canada...

..., elevated gas, and high ROP during drilling, supplemented by sample descriptions indicated good porosity and potential pay-zone. Unfortunately, this assumption was not always the case, as illustrated clearly by PC et al. 6-32HZ14-32-43-4w5. In this well, it was decided to drill parallel to the bedding plane...
