Book excerpt: Well drilling is an important process for extracting oil, natural gas, water, and mineral materials. Opening wells requires boring through earth formations, which can range from very soft to very hard. Penetrating into such formations requires specialized tools and operation procedures which should be employed based on the environment and application. Rotary drilling, in which a drill bit is used to crush the rock and penetrate into the formation, is one of the main methods of well drilling. Rotary cone bits are one of the main types of drill bits used for rotary drilling. There are two main problems encountered when drilling with rotary cone bits. Excessive vibration can cause damage to the entire system and can decrease efficiency of the drilling process. Failure of the bit's bearings and seals can also result in damage to the bit and cessation of the drilling process. In recent years, a great deal of research has been undertaken to address these problems and find appropriate solutions to improve drilling efficiency and production rate while reducing the overall cost of drilling. In this thesis, a new design for rotary cone bits, with the objective of improving overall drilling performance, is presented. First, a new pattern for distribution of inserts over the cone is presented, which results in reduced vibration of the drillstring. Second a new design for the bit's bearings is introduced that is capable of operating in harsh environments. Finally, an experimental set-up is introduced to evaluate the performance of the proposed designs.

Book Synopsis Study of Belleville Springs and Bond Graph Analysis of Passive Vibration Assisted Rotary Drilling Tool by : Dipesh Maharjan
Download or read book Study of Belleville Springs and Bond Graph Analysis of Passive Vibration Assisted Rotary Drilling Tool written by Dipesh Maharjan and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 2008, the effect of active/passive sources of drilling vibration has been a topic of research at the Drilling Technology Laboratory of Memorial University of Newfoundland. Drill-off tests have been conducted in many different settings using fully instrumented lab-scale drill rigs (Small Drilling Simulator (SDS) and Large Drilling Simulator (LDS)) and through field trials in order to validate these effects and the researchers have been able to acquire substantially prominent results, which is evident from improved drilling rates and increased dynamic downhole weight on bit (DDWOB). One of the outcomes from those experiments is the development of novel passive Vibration assisted Rotary Drilling (p-VARD) Tool, which harnesses the vibration generated at bit-rock interface to improve the drilling rate and the measured DDWOB. The p-VARD tool uses different configuration of Belleville springs and elastomer to produce desired value of tool compliance and modify the damping. The research outcomes in this thesis explain the dynamic behaviour of the p-VARD tool and helps us understand the actual phenomenon inside the tool, which results in this behaviour. Mass-spring-damper schematics of the rigid and compliant drilling systems are analyzed with the help of bond graphs in 20-sim. Results show that the p-VARD can lower the drill string natural frequency significantly enabling it to resonate at the frequencies of the top drive. In order to facilitate the p-VARD experiments in a more controlled environment, the tool has been designed for the LDS, which is more advanced than the SDS. The dynamic simulation of the Belleville springs is in itself, a separate area of research that is used for the dynamic analysis of the p-VARD tool design. The LDS offers a wide range of rotary speeds and weight on bit and can be operated fully automatically or manually. P-VARD experiments in LDS will enable us to characterize the tool properties in more depth. The LDS p-VARD tool is designed with a minimum safety factor of 3.4 against the maximum torque generated by the LDS. It utilizes a uniformly grooved sensor plates with five identical and one distinct cross-section, which is attached to the outer shell to track the axial movement of the tool. The tool is designed such that the torque is transmitted from the inner shaft to the outer shell through four uniformly spaced keys and for fluid transmission, a 13 mm through hole is made through the middle of the tool.
Book Synopsis Investigation of Drilling Performance and Penetration Mechanism Using Passive Vibration Assisted Rotary Drilling Technology by : Md. Shaheen Shah
Download or read book Investigation of Drilling Performance and Penetration Mechanism Using Passive Vibration Assisted Rotary Drilling Technology written by Md. Shaheen Shah and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Drilling performance is an essential goal in the petroleum and mining industry. Drilling Rate of Penetration (ROP) is influenced by the operating parameter: torque, Weight on Bit (WOB), fluid flow rate, Revolution per Minute (rpm), rock related parameters (rock type, rock homogeneousness, rock anisotropy orientation), and mechanical parameters (bit type, configuration of the Bottom Hole Assembly (BHA)). The Drilling Technology Laboratory (DTL) at Memorial University of Newfoundland has incorporated the passive Vibration Assisted Rotational Drilling Technology (pVARD) as a drilling tool. This tool includes three parts within a compliant part, a part that dampens and a torque transmitting unit that is inside the BHA of the drill string. This tool utilizes the natural vibrations of the drilling process to increase drilling efficiency and rate of penetration. In this thesis, laboratory and field drilling tests have been conducted by first and second generation pVARD tools respectively which could play a positive role in improving drilling penetration rate through modified bit-rock compliance from conventional drilling. This research aims to develop a fundamental guideline for rock strength measurement and to interlink mechanical tests for the purpose of evaluating drilling performance. The compressive rock strength has an inverse relationship with drilling efficiency. The average Unconfined Compressive Strength (UCS) and Indirect Tensile Strength (ITS) of the granite were obtained to be 168.4 MPa and 16.3 MPa respectively by the mechanical loading frame in the laboratory parameters following American Society for Testing and Materials (ASTM) standard. The pVARD operational details are important for optimal configuration and best drilling results. The study focused on designing pVARD to be consistent with a Large Drilling Simulator (LDS) selecting optimal Belleville springs. Compression tests and numerical studies have been carried out using a mechanical frame and simulation analysis respectively, for different Belleville Spring stacking scenarios. Mechanical and simulation studies with details of pre-planned drilling experiments can provide important guidelines for optimizing pVARD basics. The hysteresis effect analysis of LDS-pVARD springs also provided a coherent idea of energy dissipation during the cycle test. Depending on the rock type and drilling parameters can provide pre-settings and configurations of pVARD for optimal drilling performance. Finally, this dissertation focuses on the effects of vibration on the performance of a diamond coring bit when drilling on hard rock with a first-generation small lab scale vibration tool pVARD. Thereafter, Drill off Tests (DOTs) have been performed using a Small Drilling Simulator (SDS) with axial vibrations on the drill string in laboratory conditions. The vibration properties have been adjusted to various settings of spring compliance and dampening (rubber) material. The results of the evaluation of the experimental data show that the ROP increased by a maximum of 28% keeping WOB within the operational limits. The results and knowledge obtained from this study will help to design third generation pVARD tools.

Available in PDF, EPUB and Kindle. Book excerpt: Through direct exploration of the subseafloor, U.S.-supported scientific ocean drilling programs have significantly contributed to a broad range of scientific accomplishments in Earth science disciplines, shaping understanding of Earth systems and enabling new fields of inquiry. Scientific Ocean Drilling: Accomplishments and Challenges reviews the scientific accomplishments of U.S.-supported scientific ocean drilling over the past four decades. The book evaluates how the programs (Deep Sea Drilling Project [DSDP], 1968-1983, Ocean Drilling Program [ODP], 1984-2003, and Integrated Ocean Drilling Program [IODP], 2003-2013) have shaped understanding of Earth systems and Earth history and assessed the role of scientific ocean drilling in enabling new fields of inquiry. This book also assesses the potential for transformative discoveries for the next proposed phase of scientific ocean drilling, which is scheduled to run from 2013 to 2023. The programs' technological innovations have played a strong role in these accomplishments. The science plan for the proposed 2013-2023 program presents a strong case for the continuation of scientific ocean drilling. Each of the plan's four themes identifies compelling challenges with potential for transformative science that could only be addressed through scientific ocean drilling, although some challenges appear to have greater potential than others. Prioritizing science plan challenges and integrating multiple objectives into single expeditions would help use resources more effectively, while encouraging technological innovations would continue to increase the potential for groundbreaking science.
