• Works on the same principles as a Radar system Works on the same principles as a Radar system measuring timing of the returnmeasuring timing of the return

• The shorter wavelength allows the Laser to measure The shorter wavelength allows the Laser to measure much smaller objects than a Radar systemmuch smaller objects than a Radar system

Two most common types of systems:Two most common types of systems:

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 SystemsAirborne Systems

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.

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...

LiDAR DatasetsLiDAR Datasets

Energy Sector

• LiDAR datasets are available thru several vendors

• Libraries of existing data cover a large portion of AB and NE BC

• The data is compiled over years from many sources

• Data can be purchased specific to client needs

AvailabilityAvailability

Areas not covered are available to be flown by LiDAR acquisition companies with the note that:

•LiDAR firms fly internationally-availability•Fights must take place without snow cover (shorter season)•Flying small areas may be cost prohibitive

Acquiring new DataAcquiring new Data

1. Large project areas can be visualized, and analyzed allowing for fast accurate planning of wellsites, access roads, pipelines & facilities.

2. Days of field scouting in difficult or remote locations are condensed into hours of pre-planning done in the office or web based meetings.

3. Costly helicopter scouting time is minimized.

4. Various regulatory approval timelines for applications can be decreased.

5. LiDAR is non-intrusive technology which provides both Environmental and Safety benefits.

6. All concerned parties are involved in decisions making (Land, Geology, Engineering, Construction, Survey, Consultants)

Benefits to Energy SectorBenefits to Energy Sector

1. Understanding the data, and the volume of information

2. Availability of Data and costs for exploration programs

3. Using current Datasets

LiDAR ChallengesLiDAR Challenges

Through consultation within the Oil & Gas Industry we have found the most common uses for this data is:

• 3D Terrain Models• Spot Elevations/Tree Heights• Contour Maps• Cut and Fill Calculations• Profiles• Exporting subsets of data for use in other applications

•Prepare map for field scouting and application process

Save time • Days of field scouting in difficult or remote terrain are condensed into hours of pre-planning done in the office or web meeting

• All concerned parties are involved in decisions up front, reducing field time waiting for decisions to be made at head office level

• Reduced time to prepare and submit regulatory applications

Cost Benefits• Survey costs reduced by optimizing locations prior to field work

• Costly helicopter and scouting costs are minimized

Environmental Benefits• Make informed decisions regarding site locations and access reducing ground disturbances through fewer field revisions

Safety Benefits• Minimizing the total man hours in difficult or remote terrain
