  Re: Reserves & Economic Evaluation
    SEC Year End 2009
    Permian Properties


Pursuant to your request, an engineering and economic evaluation was prepared for projected oil and gas reserves associated with interests owned by Gulfport Energy Corporation (“Gulfport”) in the Permian entity, operated by Windsor Energy Group, LLC (“Windsor”). The properties include sixty-four (64) Proved Producing (PDP) wells, sixteen (16) Proved Behind-Pipe (PDBP) wells, two (2) Proved Non-Producing (PDNP) wells and one hundred ninety-one (191) Proved Undeveloped (PUD) locations. Remaining reserves and future and present worth values for these properties were calculated as of January 1, 2010. The attached Exhibit A lists the wells included in the evaluation as well as other pertinent information.

The total gross and net reserves and future cumulative cashflows, both undiscounted and discounted (at 10%) prior to considering the effects of Federal Income Taxes for all properties, are summarized in TABLE 1 below. Economics were prepared using the yearend 2009 SEC price forecast.

The reserve classifications meet the criteria for Proved reserves under the SEC guidelines as of January 1, 2010. All working and net revenue interests were provided by Gulfport. Historical production and geological data was provided by Windsor and was supplemented by data gathered from public sources. All of the information provided to us or gathered by us was assumed to be accurate and correct and was not independently verified.

Results of the evaluations showing forecasts of production, reserves, revenues, and income for each well are presented in a yearly format, and are attached and made part of this reports appendices. The gross production graphs and forecasts (by well/lease) and a one-line economic summary (by well/lease) of the results from the evaluation are also included in the appendices.



Future net revenue in this report includes deductions for state production taxes. Future net income is after deducting production taxes, future capital investments, and lease operating expenses, but before consideration of any state and/or federal income taxes. No provisions for salvage value or abandonment costs, which are generally assumed to offset each other, were been included in this evaluation. Future net income has not been adjusted for any outstanding loans that may exist or cash on hand or undistributed income. The future net income has been discounted at various annual rates, including the standard ten percent (10%), to determine its “present worth.” The present worth is shown to indicate the effect of time on the value of money.


The reserves and economic evaluation was performed using yearend 2009 SEC prices of $61.18/bbl oil, $3.87/mmbtu gas and $0.70/gal NGL, based on WTI at Cushing postings. Product prices were adjusted to reflect BTU content, field losses and usage, and gathering and processing costs. The realized oil price reflects a downward adjustment of $2.34/bbl based on the oil sales contract for 2009 provided by Windsor. The realized gas price reflects a downward adjustment of 6.01%. Oil and gas prices were held constant for the life of the well.

The plant statements for each lease were provided by Windsor and analyzed to determine the natural gas liquids (NGL) Yield and the percent loss of wellhead gas, Shrink factor. These parameters were entered into the economic model to forecast the NGL production.


Individual well operating expenses for the previous twelve months were taken from actual lease operating statements provided by Windsor. These expenses were analyzed and adjusted to calculate the average re-occurring monthly expense for each well less water disposal costs. Water production for each well was forecasted and expensed at $1.25 per barrel for all areas. A new salt water disposal well in the Bloxom area will be online in March 2010 and the salt water disposal costs were reduced in the economic analysis to $0.25/bbl.


Future well drilling and completion costs were provided by Windsor and estimated to be $1.265 MM per well based on historical data and current AFE’s provided. Recompletion costs were assumed to be $100,000 per well. Capital timing for the first three (3) years was provided by Windsor. Pinnacle cannot be responsible for capital costs that exceed or are less than these estimates.



Remaining recoverable reserves are those quantities of petroleum that are anticipated to be commercially recovered from known accumulations from a given date forward. All reserve estimates involve some degree of uncertainty depending primarily on the amount of reliable geologic and engineering data available at the time of the estimate and the interpretation of these data. The relative degree of uncertainty is conveyed by classifying reserves as Proved (highly certain) or Non-Proved (less certain). Detailed reserve definitions are provided in attachments to this report.

The estimated reserves and revenues shown in this report were determined by SEC standards for Proved Developed Producing (PDP) reserve category. Proved reserves are those quantities of petroleum which, by analysis of geological and engineering data, can be estimated with reasonable certainty to be commercially recoverable, from a given date forward, from known reservoirs with defined limits and under current economic conditions, operating methods, and government regulations.

Proved Developed Producing (PDP) is assigned to wells with sufficient production history to allow material balance and decline curve analysis to be the primary methods of estimation. PDP reserves are the most reliable reserves, generally with a high degree of confidence (>90%) that actually recovered quantities will equal or exceed published reserve estimates. Proved Developed Non-Producing (PNP) reserves include zones that have been penetrated by drilling but have not produced sufficient quantities to allow material balance or decline curve analysis with a high degree of confidence. This category includes Proved Developed Behind-Pipe (PNPBP) zones and tested wells awaiting production equipment (PNP).

Proved Undeveloped (PUD) reserves are those quantities of petroleum that are estimated to be recovered from undrilled acreage (locations) in a continuous portion of the Proved Developed reservoir as defined by offsetting PDP wells and geological interpretations. The Proven Undeveloped and Non-Producing wells were forecasted based on geological data presented, volumetric calculations, and analog comparisons to existing completions. Non-Proven (Probable) Undeveloped locations have been evaluated to be likely productive but do not meet SEC criteria to be classified as Proved at this time.


The reserves and values included in this report are estimates only and should not be construed as being exact quantities. The reserves were estimated using industry accepted engineering practices and were primarily based on historical rate decline analysis determined from existing producers in an analogous field. When possible and practical, pressure tests, material balance techniques and analogies were integrated into the reserve estimates. As additional pressure and production performance data becomes available, reserve estimates may increase or decrease in the future.

The revenue from these reserves and the actual costs to produce may be more or less than the estimated amounts and may consequently cause an increase or decrease in future reserve estimates. In evaluating the information available for this analysis, items excluded from consideration were all matters as to which legal or accounting, rather than engineering interpretation, may be controlling. Because of governmental policies and uncertainties of supply and demand, the prices actually received for the reserves included in this report and the costs incurred in recovering such reserves may vary from the price and cost assumptions referenced. Accordingly, note that as in all aspects of oil and gas evaluation the accuracy of any reserve estimate is solely a function of engineering interpretation and judgment and should be accepted with the understanding that future production or unanticipated events subsequent to this report could justify revision of these reserve estimates – either increases or decreases.
