ENHANCING SUSTAINABILITY IN THE CONSTRUCTION OF

SURFACE TRANSPORTATION INFRASTRUCTURE FOR THE OIL

& GAS INDUSTRY

P. Rodger Keller, P.E.Scott Environmental Services, Inc.

Oil & Gas Environmental Conference 2015 Dallas, TX

Overview

• Oil & Gas Surface Transportation Infrastructure

• Causes of Poor Infrastructure Condition• Results of Poor Infrastructure Condition• Sustainable Solutions • Benefits from Sustainable Solutions• Summary

3

Oil & Gas Surface Transportation Infrastructure

• Lease / Access Roads• Drilling Location Pads

• Compressor Station Pads• Other Load- or Traffic-

Bearing Surface Transportation Infrastructure

4

Poor Infrastructure Condition

CAUSES• Lack of Engineering / Planning• Poor Construction & Maintenance Practices• Lack of Quality Control• Heavy Traffic Loading

5

Engineering / Planning (Lack Thereof)

• Soil Conditions • Slope Stability – Erosion & Sediment Runoff– Safety

6

Poor Construction & Maintenance Practices

• Road Surface? • Fill Slope Maintenance– Drainage – Erosion Control

7

Quality Control (Lack Thereof)• Material Performance• Consistency

• Specifications? What Specifications?

8

Traffic Loading• Rig• Tanks & Equipment

• Materials• Truck Volume

Infrastructure Issues: Adverse Impacts on Operations

Drilling

12

Infrastructure Issues: Adverse Impacts on Operations

Production

13

Infrastructure Issues: Safety & Liability

• Vehicle Accidents• Spills

• Movement of Personnel, Equipment, & Materials

14

Infrastructure Issues: Environmental Impacts

Erosion & Sediment Runoff

15

Infrastructure Issues: Environmental Impacts

Sediment Runoff into Bodies of Water

16

Sustainable Solutions

• Least Cost of Ownership• Engineering / Planning• Sound Construction Practices• Reduce Use of Virgin Materials and

Quantities of Materials Requiring Disposal

20

Least Cost of Ownership• Expected service life of

road / pad

• Cost to own and operate throughout service life– Initial construction cost

– Maintenance costs over service life

• Incorporate economic and environmental sustainability

Engineering / Planning• Number of wells• Service life• Expected traffic loading• Soil / Rock Conditions• Slope Stability

22

Sound Construction Practices

• Construction Equipment• Site Preparation• Compaction• Materials• Erosion & Sediment

Control

25

RESULTS OF SUSTAINABLE PRACTICES

26

Fewer Adverse Impacts on Operations

27

Safer

28

Reduced Environmental Impacts

• Reduced erosion • Reduced sediment runoff

29

Reduced Environmental Impacts

• Reduced use of virgin materials

• Reduced volumes of materials requiring disposal

30

Reduced Environmental Impacts

REDUCED TRUCK TRAFFIC!

31

Summary• Poor infrastructure condition creates

adverse operational, safety, environmental, and financial impacts

• Evaluate life-cycle costs and sustainability

• Properly designed and constructed infrastructure reduces adverse impacts, increases sustainability, and saves money
