drilling for everyone

Well Construction Overview

• Where drilling fits in the E&P process and interaction with other domains
• What information is required and available from well construction group
• The different risks involved in well construction
• Roles and responsibilities of the wellsite and office drilling team
• Different rig types and main equipment used in well construction

Well Design Overview

• The well planning/design process including data inputs e.g. Pore Pressure, Frac Gradient, rock mechanics, lithology and completion requirements
• Typical time line for well planning/design and long lead items e.g. rig selection, tubulars and well heads
• Offset well analysis
• Well timing, costs, risks and AFE generation
• Impact of surface constraints in well design e.g. existing wells on pad, anti-collision requirements
• Impact of rig capability in well design
• Drilling fluid selection including drilling performance, environmental constraints and formation damage
• Basic Casing and Cementing

Directional Drilling and Deviation Control

• Types of directional wells and their applications
• Different deflection tools and directional BHAs and their functions
• Bit types, features and their application
• Understanding of the log data and offset information with respect to drilling requirements
• Capabilities of steerable systems (Motors, turbines and RSS)
• Geodetics and coordinate systems
• Requirements of wellbore surveying and the effect on target sizing

Well Control

• Causes of kicks, prevention, detection; and significance of underground and surface blowouts
• Causes and significance of shallow gas including prevention through use of shallow gas seismic surveys
• Typical well control equipment including drilling BOPs, wireline pressure control equipment, Christmas trees

Well Execution and Operations

• Well construction activities (e.g. casing, logging, cementing, completions) required to meet the specified well objectives
• Typical drilling problems including stuck pipe, kicks, wellbore instability and lost circulation including the causes and mitigation
• Operational risks e.g. Rig equipment failures and potential consequences

Realtime operations

• The real-time concept and infrastructure
• The various applications of real-time monitoring
• The value of the real-time measurements
• The interpretation of the real-time measurements
