MWD / LWD Principles & Applications
This course covers measurement and logging while drilling. Participants study tool principles and configurations, directional and survey measurements, telemetry systems and data rates, gamma ray, resistivity, density, neutron, sonic and imaging measurements, depth and environmental corrections, log quality control, applications in geosteering and evaluation, and operational planning.
Description
Measurement while drilling provides directional and drilling data in real time; logging while drilling adds formation measurements made behind the bit before the hole is disturbed. Together they support steering, formation evaluation, pore pressure monitoring and drilling optimisation, and in many wells they replace wireline logging entirely.
This course covers the tools and their use. It starts with tool principles, bottomhole assembly configurations and power supply, then covers directional and survey measurements and their accuracy, and telemetry systems including mud pulse, electromagnetic and wired pipe, with the data rates and limitations of each. It covers the formation measurements in turn: gamma ray, resistivity, density, neutron, sonic and imaging, with what each responds to and the environmental corrections required. The course then covers depth control, real-time versus memory data, log quality control, and the applications: geosteering, formation evaluation, pore pressure monitoring and drilling optimisation, closing with operational planning and tool reliability.
Measurements are made behind the bit, not at it. The distance from bit to each sensor determines how much hole is drilled before a formation is measured, which matters for geosteering and for pore pressure monitoring where decisions depend on knowing what has just been drilled. Tool configuration is therefore a planning decision with operational consequences.
Telemetry limits what arrives in real time. Mud pulse systems transmit at low data rates, so only a selected subset of measurements reaches surface while drilling, with the full data recovered from memory after the run. Deciding what to transmit, at what resolution, is part of planning the run.
Log quality control is different from wireline. Tools measure while rotating and vibrating, in a hole that may be enlarged, with drilling fluid invading, and depth comes from surface measurement rather than from a cable. Understanding these effects is what separates a usable log from a misleading one.
By the end of this training, participants will be able to:
- Describe measurement and logging while drilling tool principles and configurations.
- Explain power supply, batteries and turbine generation.
- Describe directional and survey measurements and their accuracy.
- Compare telemetry systems and their data rate limitations.
- Interpret gamma ray, resistivity, density, neutron and sonic measurements.
- Apply imaging and azimuthal measurements.
- Apply depth control and environmental corrections.
- Apply quality control to logging while drilling data.
- Use the data for geosteering, formation evaluation and pore pressure monitoring.
- Plan runs, manage tool reliability and specify data deliverables.
The course is instructor-led. Tool principles are covered with drawings and specifications, and measurements through log examples with participants interpreting real data and identifying quality problems. Planning exercises cover tool selection and configuration for stated objectives. Participants are encouraged to bring their own logs for discussion.
Organisations sending participants to this training will:
- Specify measurement and logging while drilling runs that meet the objective.
- Improve data quality and reduce unusable logs.
- Support geosteering and pressure monitoring with the right measurements.
- Reduce tool failures and lost data through better planning.
- Improve technical oversight of logging while drilling services.
Participants will:
- Understand how each measurement while drilling tool works.
- Be able to interpret logging while drilling data.
- Understand telemetry and its limitations.
- Be able to apply quality control to the data.
- Be able to plan runs and specify deliverables.
