Vertical Integration Strategy

Since beginning our vertical integration strategy with a single tubing

trailer, we’ve constructed over 50 rigs and drilled thousands of wells

We’ve Done This Before –

Encore

Development

Maximizing returns by reducing drilling and operating costs

Pursuing projects that permit development from existing cash flow,

without the need to tie up excessive capital “building reserves”

Exploration

Prioritizing opportunities, balancing risk with reward and near-term with

longer-term projects, resulting in advancing projects with asymmetric

upside

Working to

reduce

costs

utilizing

our

own

equipment,

planning

for

“scale,”

and partnering out risk

Joint Venture Opportunities

Seek to lower risk and accelerate activity

Expand our opportunities

GOAL

Create a fully funded, international, vertically integrated E&P company
