Escalera 3D
Alto Verde 3D
Question 1 ‐ Where are they and how do I get there?
First Look - Google Earth
More local geographic information from Google Earth
Escalera – area looks cultivated, close to a small city Alto Verde - area looks undeveloped, one river and one highway cross the project, maybe some cultivation near the river
NASA satellite image, Escalera
Exploration leads from 2D mapping
Leads surrounded by migration aperture
Nominal source (red) / receiver (blue) layout
Initial survey grid pre‐plot
Some surveys look like their pre‐plot…

PrePlan Receiver Layout, Version 6
Detail of receiver locations
Receivers moved to field boundaries based on imagery
Virtual scouting u
Receivers were only part of the challenge
u
Needed to place source points also
u
At each source point, we needed access for vibrators
u
Most points were on roads, but some were needed on private property
u
Looking over the fence just isn’t effective
u
This was also achieved using imagery
17
Seismic Source ‐ Vibroseis
2 Vibrators per fleet, Each 30’ long Each 60,000 lbs
18
Source planning from the ground was impractical
19
Source Scouting using Satellite Image Imagery used to identify wide, open stretches of private access before contacting landowners
20
from virtual to real
21
Processes and advantages u
Receivers moved to field boundaries, then out of no‐ permit zones into permit zones, where possible
u
95% of receiver relocations done before survey start
u
All source location done using GIS and imagery
u
Cable‐less acquisition system allowed complete flexibility u
No fixed station interval
u
No cables between stations
u
No requirement for continuous lines connected together
u
In coverage‐problem areas, additional receivers could be added into known‐good permit areas

u
Initial filtering of parcels needing permits u
Made an otherwise impossible task possible
u
Over 8,000 parcels within the survey envelope
u
Only 1,000 of over 8,000 actually had receiver stations
Identification and count of no‐permit receivers u
Joined receivers to permit polygons
u
Selected by permit status
Identification of priority no‐permits with most receivers u
Selected receivers with no‐permit
u
Calculated receiver count per unique landowner name
Permit progress monitoring u
Simple permitted parcel count or area not meaningful
u
Permitted receivers was key statistic
