Improving Accuracy of Well Depth and ROP
SPE/IADC International Drilling Conference and Exhibition, 2019Abstract This paper presents a theory and formulas for correction of the drillstring length as a function of loads, such as tension force, fluid pressures and temperature. The effects being specifically addressed are static and dynamic tensional stretch, pressure ballooning, hydrostatic shortening, flow lift shortening, and thermal ...

A ROP prediction approach based on improved BP neural network
2014 IEEE 3rd International Conference on Cloud Computing and Intelligence Systems, 2014Effective prediction of ROP (Rate of Penetration) is a crucial part of successful well drilling process. Due to the penetration complexities and the formation heterogeneity, traditional way such as ROP equations and regression analysis are confined by their limitations in the drilling practices.

ROP Improvement in Hard Formation Drilling Using Large Size PDC Cutters
ABSTRACT: With the ongoing development of oil and gas drilling equipment, the weight on bit, torque, and hydraulic energy in shallow formations are now sufficient for conventional bits. The study shows that under sufficient energy supply, optimizing PDC bits with larger-diameter cutters can significantly enhance the

Enhancing Drilling Response and Improving ROP on PDC Bits by Utilizing 1-in. Diameter Cutters
SPE/IATMI Asia Pacific Oil & Gas Conference and Exhibition, 2021Abstract This paper details the improvements to drilling performance and torsional response of fixed cutter bits when changing from a conventional 19-mm cutter diameter configuration to 25-mm cutter diameters for similar blade counts in two different hole sizes.

Abstract A critical cost in future deep oil and gas recovery is the cost to drill a well. This cost is dominated by the rate of penetration (ROP) that becomes increasingly important with increasing depth. Improving the technology of drilling and increasing the ROP will lower the cost to drill a well.

Use of MWD for Turbodrill Performance Optimization as a Means To Improve ROP
SPE Drilling Engineering, 1986Summary Field tests were carried out to monitor the performance of turbodrills driving polycrystalline-diamond-compact (PDC) bits. Separate tests with miid-pulse measurement-while-drilling (MWD) tools involved measurement of the rotational speed of the bit and downhole torque.

Hybrid Solution Improves ROP and Borehole Quality in Challenging Large Diameter Holes
SPE/IATMI Asia Pacific Oil & Gas Conference and Exhibition, 2015Abstract In the prolific Burgan field, South East Kuwait, new well profiles are being employed which require the 16 inch hole section to be drilled deeper. This new well profile requires drilling through interbedded abrasive sandstones and sticky shale which were previously drilled in 12 ¼ inch hole size.
