Coring Methods and Systems
This book is a practical guide to downhole rock sampling and coring concepts, methods, systems, and procedures for practitioners and researchers. Its chapters are based upon years of extensive studies and research about the coring methods and via direct and continuous communication and consultation obtained from various service and operator companies such as Baker Hughes GE, NOV, OMV, and Sandvik. The contributors discuss the state-of-the-art coring methods and systems (mainly used in the petroleum industry), which include: · conventional coring; · wireline continuous coring; · invasion mitigation coring (low invasion, gel coring, sponge coring); · jam-detection, anti-jamming, full closu...
Deep Rotary Core Drilling in Ice
Rotary drilling equipment was modified and used to obtain cores from glaciers in Northwest Greenland, Byrd Station and Little America V, Antarctica. Using cold compressed air, specially designed bits and other modifications, cores were obtained to 1345 feet in Greenland, 1000 feet at Byrd Station and the Ross Ice Shelf was penetrated to a depth of 840 feet at Little America V. In all locations cracks in the core appeared with increasing frequency at depth due to the sudden release of the overburden load when the core was cut in the air-filled hole. Special equipment and techniques developed dealt with the problem with some success. (Author Modified Abstract).
Improvement of Core Drill Methods
This report documents results of a program to evaluate effectiveness of more or less conventional subsurface samplers in obtaining representative and undisturbed samples of noncohesive alluvial materials containing large quantities of gravels and cobbles. This is the first phase of a research program to improve core drill methods. Samplers evaluated consisted of the Lawrence Livermore Laboratory membrane sampler, 4-in. Denison sampler, 6-in. Denison sampler, 5-in. Modified Denison sampler, and 3-in. thinwall drive tube. Small representative samples were obtained with the Denison samplers; no undisturbed samples were obtained. The field work was accomplished in the Rhodes Canyon area, White Sands Missile Range, New Mexico.
Coring Operations
This coring operations reference handbook is intended as a practical guide for the logging geologist to procedures, activities, and responsibilities required when bottomhole or sidewall coring is performed at the wellsite. Not all of the operations described are common practice in all logging units; however, familiarity with them is a necessary part of general ex ploration knowledge and professionalism. Chapter 1 discusses the concepts of porosity, permeability, and saturation, how these properties are determined in core analysis, and their significance in controlling rest:rvoir performance. Chapter 2 deals with the various techniques used in coring. Chapter 3 ex plains the routine role of the logging geologist in core retrieval, sampling, and qualitative evaluation. Chapter 4 details operating procedures for quantitative wellsite core analysis equipment. 1 INTRODUCTION 1. 1 GENERAL 1. 2 QUANTITATIVE CORE ANALYSIS The primary purpose of coring is to obtain rock samples of a sufficient size to obtain estimates of critical reservoir properties.
The China Continental Scientific Drilling Project
This book comprehensively introduces the drilling theory and practice behind CCSD-1 well drilling, the first stage of a key national scientific engineering project of China. In addition to access to variety of data and information accumulated decade during the project’s decade-long operation, readers also gain insight into state-of-the-art techniques and most recent achievements in China’s scientific drilling industry. Specifically, this work introduces the drilling engineering design, well site construction, and equipment and construction situation. It also provides a minute description on the new techniques that were developed for tackling the technical difficulties, expounds in detail...
