Interesting Water FactsW

AT

ER

FA

CT

OID

S

• Water is heavy (7 lbs/gal) and expensive to move

– Which makes it very local and leads to virtual water strategies

• Water has no substitute at any price

– Which makes it “perfectly price inelastic” (unlike energy and other natural resources)

• Water is becoming a much more constrained and limited resource

– There are many examples across the world of over-drafting of ground water

• Water can not remain a “free good”

– Prices continue to increase to reflect full value

– Higher prices should lead to better stewardship

The Water Value Chain in Fracing

• The owner/drilling customer is beginning to consider the entire water value chain

• (e.g. sourcing, transpiration, storage, Recycle /Reuse (clean brine and desal water) and disposal

• Flow back vs. produced water strategy changes with fracing activity

• Logistics is the primary valuation metric (reduce windshield time)

• Hub and spoke vs. empty back haul

• proven simple and reliable water solutions win the day…no silver bullet

• Solutions and strategy are different form by formation (Marcellus is very different from Eagle ford)

• Price does matter…but so does safety, reliability and good old fashion customer service

• Top down MSA’s without local relationships is a flawed strategy

• Water and energy are inextricably tied as critical global resources and fundamental to all economies

• NGP’s investment thesis is to partner with smart executive teams and bring both capital and domain expertise in energy and water sectors

• U.S. statesmen, Ben Franklin, stated “We will know the value of water when the well runs dry”
