 Reserves Definitions In Accordance With  Securities and Exchange Commission Regulation S-X
 Reserves
   Proved Oil and Gas Reserves
  1.
    
    The area of the reservoir considered as proved includes:
 a.
    
    The area identified by drilling
and limited by fluid contacts, if any, andb.
    
    Adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged
to be continuous with it and to contain economically producible oil or gas on the basis of
available geoscience and engineering data.
 2.
    
    In the absence of data on fluid contacts, proved quantities in a reservoir are limited by the
lowest known hydrocarbons (LKH) as seen in a well penetration unless geoscience, engineering,
or performance data and reliable technology establishes a lower contact with reasonable
certainty.3.
    
    Where direct observation from well penetrations has defined a highest known oil (HKO)
elevation and the potential exists for an associated gas cap, proved oil reserves may be
assigned in the structurally higher portions of the reservoir only if geoscience, engineering,
or performance data and reliable technology establish the higher contact with reasonable
certainty.4.
    
    Reserves which can be produced economically through application of improved recovery
techniques (including, but not limited to, fluid injection) are included in the proved
classification when:
 a.
    
    Successful testing by a pilot project in an area of the reservoir with properties no more
favorable than in the reservoir as a whole, the operation of an installed program in the reservoir
or an analogous reservoir, or other evidence using reliable technology establishes the reasonable
certainty of the engineering analysis on which the project or program was based; andb.
    
    The project has been approved for development by all necessary parties and entities,
including governmental entities.

    Existing economic conditions include prices and costs at which economic producibility from
a reservoir is to be determined. The price shall be the average price during the 12-month
period prior to the ending date of the period covered by the report, determined as an
unweighted arithmetic average of the first-day-of-the-month price for each month within such
period, unless prices are defined by contractual arrangements, excluding escalations based
upon future conditions.
 Developed Oil and Gas Reserves
  1.
    
    Through existing wells with existing equipment and operating methods or in which the cost of
the required equipment is relatively minor compared to the cost of a new well; and2.
    
    Through installed extraction equipment and infrastructure operational at the time of the
reserves estimate if the extraction is by means not involving a well.
 Undeveloped Oil and Gas Reserves
  1.
    
    Reserves on undrilled acreage shall be limited to those directly offsetting development
spacing areas that are reasonably certain of production when drilled, unless evidence using
reliable technology exists that establishes reasonable certainty of economic producibility at
greater distances.2.
    
    Undrilled locations can be classified as having undeveloped reserves only if a development
plan has been adopted indicating that they are scheduled to be drilled within five years,
unless the specific circumstances, justify a longer time.3.
    
    Under no circumstances shall estimates for undeveloped reserves be attributable to any
acreage for which an application of fluid injection or other improved recovery technique is
contemplated, unless such techniques have been proved effective by actual projects in the same
reservoir or an analogous reservoir, as defined below, or by other evidence using reliable
technology establishing reasonable certainty.
 Analogous Reservoir
  1.
    
    Same geological formation (but not necessarily in pressure communication with the reservoir
of interest);2.
    
    Same environment of deposition;3.
    
    Similar geological structure; and4.
    
    Same drive mechanism.

 Probable Reserves
  1.
    
    When deterministic methods are used, it is as likely as not that actual remaining quantities
recovered will exceed the sum of estimated proved plus probable reserves. When probabilistic
methods are used, there should be at least a 50% probability that the actual quantities
recovered will equal or exceed the proved plus probable reserves estimates.2.
    
    Probable reserves may be assigned to areas of a reservoir adjacent to proved reserves where
data control or interpretations of available data are less certain, even if the interpreted
reservoir continuity of structure or productivity does not meet the reasonable certainty
criterion. Probable reserves may be assigned to areas that are structurally higher than the
proved area if these areas are in communication with the proved reservoir.3.
    
    Probable reserves estimates also include potential incremental quantities associated with a
greater percentage recovery of the hydrocarbons in place than assumed for proved reserves.4.
    
    See also guidelines in Items 4 and 6 under Possible Reserves.
 Possible Reserves
  1.
    
    When deterministic methods are used, the total quantities ultimately recovered from a project
have a low probability of exceeding proved plus probable plus possible reserves. When
probabilistic methods are used, there should be at least a 10% probability that the total
quantities ultimately recovered will equal or exceed the proved plus probable plus possible
reserves estimates.2.
    
    Possible reserves may be assigned to areas of a reservoir adjacent to probable reserves where
data control and interpretations of available data are progressively less certain. Frequently,
this will be in areas where geoscience and engineering data are unable to define clearly the
area and vertical limits of commercial production from the reservoir by a defined project.3.
    
    Possible reserves also include incremental quantities associated with a greater percentage
recovery of the hydrocarbons in place than the recovery quantities assumed for probable
reserves.4.
    
    The proved plus probable and proved plus probable plus possible reserves estimates must be
based on reasonable alternative technical and commercial interpretations within the reservoir
or subject project that are clearly documented, including comparisons to results in successful
similar projects.5.
    
    Possible reserves may be assigned where geoscience and engineering data identify directly
adjacent portions of a reservoir within the same accumulation that may be separated from
proved areas by faults with displacement less than formation thickness or other geological
discontinuities and that have not been penetrated by a wellbore, and the registrant believes
that such adjacent portions are in communication with the known (proved) reservoir. Possible
reserves may be assigned to areas that are structurally higher or lower than the proved area
if these areas are in communication with the proved reservoir.6.
    
    Pursuant to Item 3 under Proved Oil and Gas Reserves, where direct observation has defined a
highest known oil (HKO) elevation and the potential exists for an associated gas cap, proved
oil reserves should be assigned in the structurally higher portions of the reservoir above the
HKO only if the higher contact can be established with reasonable certainty through reliable
technology. Portions of the reservoir that do not meet this reasonable certainty criterion may
be assigned as probable and possible oil or gas based on reservoir fluid properties and
pressure gradient interpretations.
