Hydraulic Optimization of Foam Drilling For Maximum Drilling Rate

Proceedings of SPE/IADC Underbalanced Technology Conference and Exhibition, 2004
ABSTRACT The theory of hydraulic optimization of drilling with conventional (incompressible) drilling fluids is well known and has been widely practiced in the industry. Classical theory of hydraulics optimization for maximum drilling rate calls for either the use of empirical correlations or the use of optimization theory

Maximising Drilling Rates with Real-Time Data-Driven Drilling Parameters Optimisation

International Petroleum Technology Conference, 2023
Abstract The hardness and high abrasiveness of shale formations pose great challenges for improving drilling performance with deeper and more complex unconventional gas-reservoir formations explored and developed in the Sichuan Basin of China.

Effect of drilled solids on drilling rate and performance

Journal of Petroleum Science and Engineering, 2007
Abstract This paper describes the results of laboratory investigations into the effect of drilled solids on the drilling rate and drilling performance. Drilling fluid performance and a successful result during drilling operations are characterised by the fluid's properties providing hole cleaning and cutting transport.

Regulation of Penetration Rate and Drilling Power in Rotary Drilling Systems

2020 IEEE 16th International Workshop on Advanced Motion Control (AMC), 2020
The problems of regulation of penetration rate and drilling power in rotary drilling systems are addressed. Regulation algorithms are proposed which do not require knowledge of majority of the parameters of the drilling systems and those of the rock-bit interaction.

Feed rate control in robotic bone drilling process

Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 2020
The bone drilling process is characterised by various parameters, the most important of which are the feed rate (mm/s) and the drill speed (rpm). They highly reflect the final effects and results of the drilling process, such as mechanical and thermal damages of bone tissue and hole quality.

Drilling Salt - Effect of Drilling Fluid on Penetration Rate and Hole Size

Proceedings of IADC/SPE Drilling Conference, 2002
Abstract Drilling a deep, high-pressure sub-salt well is both expensive and a mechanical challenge. There are a number of issues that create difficulty. Drilling fluid selection in the past has focused on drilling a gauge hole, with little concern on the issue of penetration rates.(rate-of-penetration.) Drilling a gauge hole is still an ...

A New Robust Drilling Rate Model

Offshore Technology Conference Brasil, 2019
Abstract Drilling rate remains a major challenge when it comes to planning and drilling workover and development wells. The main mission of a drilling engineer is to design a well optimizing time, cost, economics and safety. Analysis of previously drilled wells operations' records is required to perform optimization techniques to reduce ...

Laboratory Drilling Rate and Filtration Studies Of Emulsion Drilling Fluids

Journal of Petroleum Technology, 1967
Abstract Data obtained under controlled lest conditions using a microbit drilling machine showed that oil emulsified in water muds may either increase or decrease the drilling rate, depending upon drilling conditions.

Hydraulic Optimization of Aerated Mud Drilling for Maximum Drilling Rate

IADC/SPE Managed Pressure Drilling and Underbalanced Operations Conference & Exhibition, 2009
Abstract The theory of hydraulic optimization of drilling with conventional (incompressible) drilling fluids is well known and has been widely practiced in the industry. Classical theory of hydraulic optimization for maximum drilling rate calls for either the use of empirical correlations, such as Fullerton charts, Amoco curves, etc., or

Drilling Variables At Technical Limit Of Drilling Rate

Canadian International Petroleum Conference, 2002
Abstract Recorded drilling times may show significant variations from well to well even for the same total depth in the same field. Apart from the formation characteristics, engineers' technical ability plays an important role in determining drilling time. A drilling performance is usually compared
