1 ASTM Standards: Hydraulic Fracturing of Subsurface Formations Planning a Framework and Attaining Balance For AIPG Marcellus, Utica, and Point Pleasant Shale Conference Columbus, OH April 16, 2014 By Caryl Alfaro, CPG Earth Resource Systems LLC

2 Overview Who is ASTM? ASTM Efforts in Hydraulic Fracturing Current Work Items and Status

3 ASTM INTERNATIONAL ASTM International, formerly known as the American Society for Testing and Materials (ASTM), is a globally recognized leader in the development and delivery of international voluntary consensus standards. Today, some 12,000 ASTM standards are used around the world to improve product quality, enhance safety, facilitate market access and trade, and build consumer confidence.

4 ASTM D18.26 Subcommittee Timeline Jan D18.26 Hydraulic Fracturing Subcommittee Forms March Formation of 12 Sections December Sections Reduced to 5 Sections April 2014 One Proposed Standard in Ballot

5 Working Groups - ASTM D18.26 Hydraulic Fracturing Subcommittee Optical imaging methods for size and shape of proppant Guide for Data Management and Reporting Associated with Unconventional Oil and Gas Operations Involving Hydraulic Fracturing Sampling and Analysis of Residential and Commercial Water Supply Wells Modified Method for Determining the Crush Resistance of Proppants As of 9 Feb 2014

6 Particle Size and Shape Optical methods use high speed imaging and digital processing to determine size distribution and particle shape Faster than sieving methods Useful particle diameters greater than laser diffraction method (typically 3mm, about 7 mesh) Provides automated reporting Eliminates human bias present in the current method, especially in shape calculations (sphericity and roundness) Results are directly comparable to ASTM sieving methods WK42600 Standard Test Method for Dynamic Image Analysis of Natural Sand, Resin Coated Sand, Ceramic and other manufactured materials used as Proppants Technical Contact: Tod Canty (todc@jmcanty.com)

7 Sampling and Analysis of Water Wells Sampler Qualifications Evaluation of Well Condition / Construction Assessment of Water Supply System Property Damage Prevention Well Purging and Sampling Requirements Parameters / Analytical Categories Laboratory Certifications Preliminary Methane Screening Sample Shipment / Documentation Reporting WK42923 New Guide for Sampling and Analysis of Residential and Commercial Water Supply Wells Technical Contact: Hank Mittelhauser (HANKM@st-ma.com)

8 Crush Test Method Minimizing proppant pack porosity appears to reduce the noise inherent in these measurements. A new sample preparation procedure is in development and a round-robin is planned. Users of this standard proppant testing labs and proppant manufacturers oil field service companies and oil and gas producers geothermal operators WK44896 New Test Method for Determining the Crush Resistance of Materials Used as Proppants in Hydraulic Fracturing of Subsurface Formations Technical Contact: John Getty (jgetty@mtech.edu)

9 Data Management and Reporting This document will provide guidance on data collection, management, and reporting that can be used by various stakeholders including operators, consultants/engineers, regulatory/permitting agencies, land owners, and the general public to support decision making efforts in the above categories, and others as appropriate. Focus on 1) Public disclosure 2) Water sources, usage, quality and sampling 3) Risks-health and environmental WK42803 New Guide for Data Management and Reporting Associated with Unconventional Oil and Gas Operations involving Hydraulic Fracturing.
