A transition to alternative fuel- currently two methods

7

1. Dual Fuel- add-on

to existing engines, 51

rig installations to

date.

2. 100% Natural Gas-

new engines, 2 rig

installations to date

(2013).

Natural Gas Supply- 4 current methods

8

1. Wellhead

2. Pipeline

3. LNG

4. CNG

Push Back to Natural Gas

9

> Supply concerns due to lack

of reliable infrastructure.

> Safety concerns.

> Few first adopters.

> Concerns regarding return on

investment.

> Technology and rig

performance barriers.

> Lack of training and technical

expertise on natural gas

engines.

Economics

15

> Primary business driver today for the drilling contractor is

increased rig marketability.

> Dual Fuel System savings can be up to 70% yet average 40%.

Substitution rate is expected to improve as OEM’s enter

market.

Economics

16

> Current dual fuel

rigs diesel

consumption drops

by approx. 1,000

gpd.

> DGE (Diesel Gas

Equivalent) pricing

of natural gas is

roughly $2.10-$2.50

per gallon.

Forecast for the future (subject to change!)

17

> LNG facilities will become more

prevalent, starting with the

larger plays- Eagleford and

Bakken.

> Frac spreads and trucking fleets

will drive the conversion due to

better economics. Drilling rigs

will benefit as a result due to

improved supply chain.

> Engine technology will improve,

dual fuel will become a standard

feature if the natural price

remains low.

Forecast for the future (subject to change!)

18

> Substitution rates will improve

as the OEM’s enter the market.

> As LNG facilities become more

prevalent, 100% natural gas

engine rigs will become more

prevalent.
