Sintana Energy Announces VMM-37 Farmout Agreement with ExxonMobil 
TORONTO, Nov. 12, 2012 /CNW/ - Sintana Energy Inc. (TSX-V: SNN) ("Sintana" or 
the "Company") is pleased to announce that Patriot Energy Oil & Gas Inc. 
("Patriot"), wholly-owned by the Company, has entered into a Farmout Agreement 
(the "Agreement") with ExxonMobil Exploration Colombia Limited, a wholly owned 
subsidiary of Exxon Mobil Corporation ("ExxonMobil") (NYSE: XOM) for the 
exploration and development of unconventional oil and gas resources underlying 
the 43,000 acre VMM-37 Block in Colombia's Middle Magdalena Basin. Major 
elements of the VMM-37 Agreement are as follows: 

    --  Subject to approval by the Agencia Nacional de Hidrocarburos of
        Colombia (the "ANH"), ExxonMobil will acquire an undivided 70%
        participation interest and operatorship in the formations
        defined as unconventional by completing the Work Program
        described below.
    --  Patriot will retain the remaining 30% interest in the
        unconventional play as well as its current 100% participation
        interest in the conventional resources overlying the top of the
        unconventional interval.

    --  For purposes of this Agreement, unconventional formations are
        defined as the La Luna and deeper.

    --  ExxonMobil will pay 100% of all Exploration Phase I well costs
        (3 wells).  The estimated timing for the commencement of
        drilling operations on the first exploration well is the third
        quarter of 2013.  A consideration will be paid that will
        compensate Sintana for its past expenses connected with the
    --  ExxonMobil will have an option to proceed to the next phase. 
        In this development phase, it will pay 100% of all additional
        costs to a maximum of US $45 million, of which US $10 million
        will be recouped by ExxonMobil from 50% of Patriot's production
    --  As agreed by Patriot and ExxonMobil, as joint participants in
        the Block, good faith efforts will be made to locate
        exploration wells targeting the unconventional play in such a
        way as to also test conventional prospects.
    --  At various stages of the Work Program, as defined in the
        Agreement, ExxonMobil will have the right to withdraw from the
        project, relinquish operatorship and reassign to Patriot the
        right to the 70% participation interest it would have retained
        had it met all investments and activities requirements of the

    --  In the event that exploration and development of the
        unconventional resources continue beyond the activities and
        costs enumerated above, those costs will be shared based on the
        parties participating interests.
    --  Further exploration and subsequent development plans for the
        unconventional and conventional formations will be decided on
        once technical data obtained from drilling the deeper
        unconventional play, and other sources, are analyzed.

    --  The ANH requires that operators provide secured performance
        warranties for various phases of the contractual Work Program. 
        Sintana currently has in place a letter of credit in
        satisfaction of this requirement.  ExxonMobil will assume
        responsibility for providing these warranties resulting in the
        release of restricted Sintana funds currently on deposit to
        secure the existing letter of credit.

Sintana's CEO, Doug Manner, commented, "Both the conventional and 
unconventional formations on VMM-37 offer tremendous potential for large 
discoveries with compelling economics. ExxonMobil owns interests in, and is 
the operator of, a number of very large, highly complex unconventional 
projects in multiple countries. It is on the leading edge of developing and 
applying highly technical methods and complex processes to discover, develop 
and produce unconventional reserves. We are fortunate to have ExxonMobil as 
our partner and look forward to a long and very successful working 

The Company will host a conference call on November 13(th) at 2:00 pm (EST) to 
discuss key highlights of the transaction. A question and answer session 
will follow. Details regarding the conference call, including dial-in 
instructions, will be disclosed later today.
