How Deep Learning can Provide Consistent Improvement on ROP Through Different Drilling Environments

IADC/SPE International Drilling Conference and Exhibition, 2022
Abstract Using multidimensional analysis of historical drilling parameters combined with deep learning (DL) techniques, consistent ROP improvement in different drilling environments can be achieved. This discussion is focused on how offset well data can be properly analyzed and modeled to generate valuable outputs that improve not only ...

Hybrid Solution Improves ROP and Borehole Quality in Challenging Large Diameter Holes

SPE/IATMI Asia Pacific Oil & Gas Conference and Exhibition, 2015
Abstract 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.

Retinopathy of Prematurity (ROP) in a Developing Economy with Improving Health Care

Current Ophthalmology Reports, 2017
The purpose of this study is to highlight the changing pattern of retinopathy of prematurity (ROP) incidence with improvement in economy and health care in Africa, pointing out the challenges and recommendations for sustainable, cost-effective screening and management. ROP was initially thought to be rare in some parts of Africa.

Enhancing Drilling Response and Improving ROP on PDC Bits by Utilizing 1-in. Diameter Cutters

SPE/IATMI Asia Pacific Oil & Gas Conference and Exhibition, 2021
Abstract 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.

The Use of MPD and an Unweighted Fluid System for Drilling ROP Improvement

IADC/SPE Managed Pressure Drilling & Underbalanced Operations, 2007
Abstract A drilling technique that is increasingly being used for performance drilling purposes is Managed Pressure Drilling (MPD). MPD is typically considered a tool to mitigate drilling hazards, and reduce the resulting non-productive time due to encountering lost circulation zones, tight pore pressure/fracture gradient margins, and ...

Optimization of Deep Drilling Performance: Benchmark Testing Drives ROP Improvements for Bits and Drilling Fluids

SPE/IADC Drilling Conference, 2007
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.

Twist Compensation Reduces Trajectory Tortuosity and Improves ROP

IADC/SPE Drilling Conference and Exhibition, 2018
Abstract Twist compensation is a new, patent applied technique for improving the performance of conventional directional drilling assemblies. It is a feed-forward control technique where the reactive twist is used for controlling the angular position of the top drive thus minimizing undesired variations of the tool face.

A ROP Optimization Approach Based on Improved BP Neural Network PSO

2015
Effective optimization 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 prediction.

Drill Bits Evolution in Lump-Sum Turnkey Project Delivers Up to 70 Percent ROP Improvement

Day 1 Tue, March 23, 2021, 2021
Abstract Drilling rate of penetration (ROP) is one of the variables that influences well delivery timing and cost. ROP is affected by many factors, including but not limited to rock strength, well profile, bottom hole assembly (BHA) design, challenging formations per section, and drill bit selection.
