WPX Energy’s Niobrara Discovery Well Hits Production Milestone

  WPX Energy’s Niobrara Discovery Well Hits Production Milestone

Business Wire

TULSA, Okla. -- April 08, 2013

WPX Energy (NYSE:WPX) announced today that its Niobrara Shale discovery well
in the Piceance Basin exceeded 1 billion cubic feet of natural gas production
in just over 100 days of operation.

At this rate, WPX expects the Niobrara well to produce in its first four
months what a typical well in the Piceance Basin’s Williams Fork formation
produces over its estimated lifecycle of 25 to 30 years.

The Niobrara well is located on WPX’s acreage in Western Colorado, where the
company has the lease rights to approximately 180,000 net acres of the
Niobrara/Mancos shale play.

The discovery well initially produced 16 million cubic feet per day at a
flowing pressure of 7,300 pounds per square inch. It registered an average
production rate of almost 10 million cubic feet per day over its first 90
days, despite being choked back substantially.

“We’re very pleased with what we’re seeing,” said Ralph A. Hill, WPX’s
president and chief executive officer. “This well is demonstrating tremendous
strength. It’s a large discovery that has significant upside potential for
creating shareholder value.”

Over time, WPX believes that its Niobrara discovery has the potential to more
than double the company’s proved, probable and possible (3P) reserves, which
were approximately 18 trillion cubic feet at year-end 2012.

WPX started drilling its second Niobrara well on Wednesday, April 3. The
company expects to begin completion activities in June.

As previously announced, WPX plans to drill a total of four horizontal
Niobrara wells in 2013. The drilling plan is designed to prove up adjacent
acreage and test the repeatability of the play on additional acreage the
company owns.

WPX already has extensive processing and takeaway capacity under contract in
the Piceance to support Niobrara production.

The Niobrara and Mancos shales are generally located at depths of 10,000 to
13,000 feet. The Williams Fork is a shallower formation, generally located at
depths of 6,000 to 9,000 feet. In the Piceance Basin, WPX holds an average
working interest of 66 percent in the Niobrara and Mancos shales.

the Private Securities Litigation Reform Act of 1995. All statements, other
than statements of historical facts, included in this press release that
address activities, events or developments that the company expects, believes
or anticipates will or may occur in the future are forward-looking statements.
Such statements are subject to a number of assumptions, risks and
uncertainties, many of which are beyond the control of the company. Statements
regarding future drilling and production are subject to all of the risks and
uncertainties normally incident to the exploration for and development and
production of oil and gas. These risks include, but are not limited to, the
volatility of oil, natural gas and NGL prices; uncertainties inherent in
estimating oil, natural gas and NGL reserves; drilling risks; environmental
risks; and political or regulatory changes. Investors are cautioned that any
such statements are not guarantees of future performance and that actual
results or developments may differ materially from those projected in the
forward-looking statements. The forward-looking statements in this press
release are made as of the date of this press release, even if subsequently
made available by WPX Energy on its website or otherwise. WPX Energy does not

Investors are urged to consider carefully the disclosure in our filings with
the Securities and Exchange Commission, available from us at WPX Energy, Attn:
Investor Relations, P.O. Box 21810, Tulsa, Okla., 74102, or from the SEC’s
website at www.sec.gov.

Additionally, the SEC requires oil and gas companies, in filings made with the
SEC, to disclose proved reserves, which are those quantities of oil and gas,
which, by analysis of geoscience and engineering data, can be estimated with
reasonable certainty to be economically producible – from a given date
forward, from known reservoirs, under existing economic conditions, operating
methods, and governmental regulations. The SEC permits the optional disclosure
of probable and possible reserves. From time to time, we elect to use
“probable” reserves and “possible” reserves, excluding their valuation. The
SEC defines “probable” reserves as “those additional reserves that are less
certain to be recovered than proved reserves but which, together with proved
reserves, are as likely as not to be recovered.” The SEC defines “possible”
reserves as “those additional reserves that are less certain to be recovered
than probable reserves.” The Company has applied these definitions in
estimating probable and possible reserves. Statements of reserves are only
estimates and may not correspond to the ultimate quantities of oil and gas
recovered. Any reserve estimates provided in this presentation that are not
specifically designated as being estimates of proved reserves may include
estimated reserves not necessarily calculated in accordance with, or
contemplated by, the SEC‘s reserves reporting guidelines. Investors are urged
to consider closely the disclosure in our SEC filings that may be accessed
through the SEC’s website at www.sec.gov.

The SEC’s rules prohibit us from filing resource estimates. Our resource
estimations include estimates of hydrocarbon quantities for (i) new areas for
which we do not have sufficient information to date to classify as proved,
probable or even possible reserves, (ii) other areas to take into account the
low level of certainty of recovery of the resources and (iii) uneconomic
proved, probable or possible reserves. Resource estimates do not take into
account the certainty of resource recovery and are therefore not indicative of
the expected future recovery and should not be relied upon. Resource estimates
might never be recovered and are contingent on exploration success, technical
improvements in drilling access, commerciality and other factors.
