1 Drilling Gas Wells: Beginning to End

2 Seismic Exploration

3 Vibroseis Truck

4 Geophones

5 LOTS of geophones

6 Seismic exploration: How it works

7 3D Seismic Imaging

8 Building a Well Pad Survey – Typically 1.5 to 2.0 acres. Ready Roads – Gravel or pave as needed Remove Topsoil – For replacement later Grade – To level Gravel – Brought in to build a solid base Compact and Grade Erosion Control

9 Well Pad: Ready for the rig

10 Rig Up

11 Drilling the Well

12 During the Drilling Process Truck traffic: Up to several trips per day, bringing water, drilling mud, pipe, and supplies 24x7: Because well control must be maintained, and because the drill rig is expensive, once the rig arrives operations run around the clock. Drilling Time: Typically the actual drilling takes about a week, sometimes less. Total Time: From rig up to rig down, about a month.

13 During Drilling: How are we protective ? IDAPA : 03. Other Laws. Owners or operators engaged in the exploration and extraction of crude oil and natural gas resources shall comply with all applicable laws and rules of the state of Idaho including, but not limited to the following: ( ) a. Idaho water quality standards and waste water treatment requirements established in Title 39, Chapter 1, Idaho Code; IDAPA , “Water Quality Standards”; IDAPA , “Wastewater Rules”; and IDAPA , “Ground Water Quality Rule,” administered by the IDEQ. ( ) b. Idaho air quality standards established in Title 39, Chapter 1, Idaho Code and IDAPA “Rules for the Control of Air Pollution in Idaho,” administered by the IDEQ. ( ) c. Requirements and procedures for hazardous and solid waste management, as established in Title 39, Chapter 44, Idaho Code, and rules promulgated thereunder including IDAPA , “Rules and Standards for Hazardous Waste”; IDAPA , “Solid Waste Management Rules”; and IDAPA , “Rules Regulating the Disposal of Radioactive Materials Not Regulated Under the Atomic Energy Act of 1954, As Amended,” administered by the IDEQ. ( ) d. Idaho Stream Channel Protection Act, Title 42, Chapter 38, Idaho Code, and rules promulgated thereunder including IDAPA , “Stream Channel Alteration Rules,” administered by the IDWR. ( ) e. Injection Well Act, Title 42, Chapter 39, Idaho Code and rules promulgated thereunder including IDAPA , “Rules and Minimum Standards for the Construction and Use of Injection Wells,” administered by the IDWR. ( ) f. Department of Water Resources – Water Resource Board Act, Title 42, Chapter 17, Idaho Code and rules promulgated thereunder including IDAPA , “Safety of Dams Rules,” administered by the IDWR.

14 During Drilling: How are we protective? IDAPA : Mandates API standards for casing and cementing. IDAPA : Drilling permit may be denied if drilling will “result in... the pollution of fresh water supplies.” IDAPA : If the well will be stimulated, must file: “Fresh water protection plan that describes the proposed site specific measures to protect water quality from activities associated with well treatments. The Department will review this plan in consultation with the IDEQ.” IDAPA : If the well will be stimulated, must offer to owners within ¼ mile of the wellbore “an opportunity to have the owner or operator sample and test the water, at the owner or operator’s cost, prior to and after the oil or gas well being treated.” IDAPA : Additional monitoring of water sources may be required by IDL.

15 During Drilling: How are we protective? IDAPA : Must perform mechanical integrity testing and pressure monitoring before and after well stimulation. IDAPA : Bond of $10k plus $1 per foot for each well, or up to $150k for blanket bond. No blanket bonding for inactive wells. IDL may require additional bonding. IDAPA : Surface owner protections; bonding and requirement to attempt negotiation of Surface Use Agreement. IDAPA : Drilling rules: Conductor to 40’; surface casing to minimum of 10% of TD; casing “The casing must be seated through a sufficient series of low permeability, competent lithologic units such as claystone, siltstone, basalt, etc., to insure a solid anchor for blow out prevention equipment and to protect usable ground water from contamination”; intermediate and production casing must overlap by at least 100’. Others: Ongoing mechanical integrity testing, well plugging, pit construction standards, surface reclamation.

16 Rig Down The rig up process in reverse A wellhead will be in place Reclamation of the well pad may begin Owners may decide to keep the well pad in place for their own use

17 Flare Testing

18 Pad Reclamation: Removing the gravel base

19

20 Pad Reclamation: Returning the topsoil

21 Pad Reclamation: Returning the surface contour

22

23 Pad Reclamation: Seeding…..

24 Or planting

25 Reclaimed Pad

26 What if the well is a success? Flow lines will be installed underground from the well to the gathering line, which will connect to the Northwest Pipeline A few pieces of equipment may be placed at the well pad, to separate liquids (water or condensate) so the gas may be sent downstream for further processing Small tanks may be placed at the well pad, to store liquids that are removed at the well for periodic loading and removal by truck

27 Liquids Storage
