Introduction to Rig Types and Basic Drill String Components

The first Oilwell Drilling module covers basic oil and gas well drilling principles. Different types of drilling rigs are presented, the difference between a kelly/rotary table and a top drive system is explained, and the components of a drill string are described in detail.

Basic Blowout Prevention Equipment Components

A blowout represents the single most dangerous threat to human life and property during the drilling process. This module explains the causes of a blow-out and covers the tools and methods used to control and prevent drilling kicks.

Introduction to Drilling Fluids

Volume 3 concerns the function of drilling fluids in drilling operations. The module covers the physical properties of drilling mud, the advantages of mud additives, and the importance of mud testing. Procedures for drilling with air and foam are also discussed.

Mud Circulation and Treating Equipment

Volume 4 presents a comprehensive overview of the mud circulation and conditioning systems on a drilling rig. It follows the flow of mud step-by-step through the system and explains the function of all circulation components.

Hoisting Equipment

The purpose and operation of a rig’s hoisting system are covered in the fifth Oilwell Drilling module. All important elements are described in detail, from the drawworks to the traveling block.

Rotating Equipment, Mast, and Substructure

Volume 6 addresses both the kelly/rotary table and top drive systems, and discusses the advantages of each in various drilling operations. The module also explains the function and characteristics of masts and derricks, and the components of the substructure.

Pipe Handling

This module describes the process of tripping pipe and making connections with kelly and top drive rotary systems. It also explains the use of slips and elevators, describes the features of a driller’s console, and introduces innovations such as the iron roughneck.

Casing and Cementing

Casing and primary cementing operations are covered in the eighth volume of Oilwell Drilling. The module examines the purpose and qualities of basic casing strings and liners, describes casing accessories, and explains the cementing procedure from start to finish.

Well Logging, Mud Logging, and Drill Stem Testing

Volume 9 explains the need for careful testing to determine the commercial potential of a well prior to completion. Methods and tools for mud logging, well logging, and drill stem testing are described in detail.

Power Systems and Instrumentation

The various types of power systems found on the rig are presented in this module: AC to DC, DC to DC, mechanical, hydraulic, and pneumatic drive systems. The module emphasizes the importance of prime movers and concludes with a review of rig instrumentation.
