... these models provide valuable insights on selecting optimal heat-management techniques during circulation, none consider the effect of drilling rate of penetration (ROP) on downhole temperature, and all consider the wellbore as having fixed and static dimensions. On the other hand, the effect of ROP...

The following key indicators and objectives were established: - Validation of drilling-software work flows - Achievement of a 75% average in automation control - Improvement of rate of penetration (ROP) by 5...

... polycrystalline diamond compact (PDC) cutters. This allows it to maintain drilling efficiency in hard, interbedded formations, leading to a higher overall rate of penetration (ROP) for the interval. When drilling in hard, abrasive formations, heat generated from the rock-cutter interaction can break down...

...Graham Mensa-Wilmot Drilling-efficiency improvements must guarantee consistent reductions in project cost. The industry continues to pursue this critical requirement through different approaches—rate of penetration (ROP) maximization or cycle-time improvement. Recent advancements in technology...

... in an onshore field in Iraq using different bit designs and with a variety of downhole conditions. To improve the rate of penetration (ROP) in a significant manner, a radical shift in how drill bits are selected, as well as a closer look at bit characteristics, is needed. This work aims to combine analytical...

... drilling the 8.5-in. section, which the operations team had to time-drill when drilling the sidetrack window to ensure that the kickoff was at the correct trajectory. The controlled rate of penetration (ROP) necessary to achieve this had resulted in a low average ROP for Well 2. Nevertheless...

... of penetration (ROP) on the basis of optimal drilling parameters was the key to tackling these issues. A formal process for optimizing performance was developed, with a focus on optimizing polycrystalline diamond compact (PDC) bit design and drilling hydraulics and developing a drillers’ road map. As a result...

... to continually improve rate of penetration (ROP) and drilling performance. An intelligent drilling advisory system (IDAS), based on a soft closed-loop solution with multiple regression analysis—called optimum parameters global retrieval—has been established. As an effective tool for further achieving the optimal...

... in lowering breakeven prices on shale horizontal wells. Even though the idea was suspected some time ago, recent studies have established some correlations between wellbore quality (quantified by various tortuosity indexes) and rate of penetration (ROP), occurrence of vibrations, and production. One...

... and hole-cleaning limitations. The salt section would be very drillable, but mechanical specific energy (MSE) levels would be approximately 40 ksi. PDC bits would be very aggressive, so torque would be highly sensitive to weight on bit (WOB). Peak rate of penetration (ROP) in both salt and sediments would...

... cabin over a fiber-to-serial cable to the computer in the driller’s cabin. The DAS helps the driller make decisions for managing controllable drilling parameters to enable a high rate of penetration (ROP) and low vibrations. The system uses surface data only (i.e., data obtained from sensors...

...Slim Hbaieb; Julien Converset; Jason Foster; Yezid Arevalo Technology Update Less than a decade ago, the key to optimizing wellbore economics centered mainly on drilling faster and improving rates of penetration (ROP).

.... Among the many challenges on a project of this magnitude was the need to drive well-construction costs down. An important aspect of well-construction cost is the time spent drilling, which is largely influenced by the slow rate of penetration (ROP) prevalent in the field because of the high rock...
