Light Detection and Ranging Technology for Energy Sector


Published on

The advancement of technologies in the last decade is no surprise to anyone. LiDAR although new to some has been around for some time, haven’t heard of it? What are you missing?

This presentation will briefly explain what LiDAR is and how it is gathered, but the primary focus will be on how the Energy Sector can benefit from its use. We will show several example project datasets, tools developed and available to industry, and how this growing technology can change how you look at your projects.

Additionally, we will show how involving all members of your exploration team in a LiDAR planning process will save time and money while increasing safety and reducing environmental impact. Your well location may begin with Geology calculating back to a surface location, but the finial location can affect many other decisions your company may make…good planning makes for good decisions.

Chris Martin is a Survey Technologist with 17 years of experience in the surveying profession. His field survey career has involved major projects with TransCanada Pipelines and Alliance Pipelines along with many conventional oil and gas programs. For the last 4 years he has primarily focussed on business development and is currently a Marketing Representative for Can-Am Geomatics.

  1. 1. <ul><li>Canadian Association </li></ul><ul><li>of Drilling Engineers </li></ul><ul><li> </li></ul><ul><li>Technical Presentation </li></ul>
  2. 2. <ul><li>What is LiDAR? </li></ul><ul><li>How is it gathered? </li></ul><ul><li>What information is available? </li></ul><ul><li>What are the benefits/challenges? </li></ul><ul><li>What LiDAR tools are available? </li></ul><ul><li>Planning for success - Sample Ops Meeting </li></ul>Introduction
  3. 3. Light Detection and Ranging (LiDAR) What is LiDAR? <ul><li>Measuring system that uses a Laser to measure a distance to a target </li></ul><ul><li>Works on the same principles as a Radar system measuring timing of the return </li></ul><ul><li>The shorter wavelength allows the Laser to measure much smaller objects than a Radar system </li></ul><ul><li>Makes it ideally suited for airborne terrain mapping </li></ul>
  4. 4. What is LiDAR? Terrestrial Scanners Airborne Systems Two most common types of systems:
  5. 5. LiDAR sensors are attached to an aircraft and send pulses of light toward the ground. The time difference between the sending of the pulse and the return of the reflected light to the aircraft is then measured. Airborne Systems
  6. 6. The aircraft uses GPS and inertial measurement units to reference its location to a ground based control system. This produces an accurate x,y,z position. Airborne Systems
  7. 7. Dataset is processed by the LiDAR vendor to remove noise and to separate ground points from surface features, such as trees, buildings, power lines etc... Bare Earth (Ground Points) Full Feature LiDAR Processing
