Proved reserves Those reserves that can be estimated with a high degree of certainty to

be recoverable. It is likely that the actual remaining quantities recovered will exceed the estimated proved reserves.

Probable reserves Those additional reserves that are less certain to be recovered than

proved reserves. It is equally likely that the actual remaining quantities recovered will be greater or less than the sum of the estimated proved + probable reserves.

Reserves The estimated remaining quantities of oil and natural gas and related

substances anticipated to be recoverable from known accumulations, as of a given date, based on the analysis of drilling, geological, geophysical, and engineering data; the use of established technology; and specified economic conditions, which are generally accepted as being reasonable. Reserves are further classified according to the level of certainty associated with the estimates and may be subcla ssified based on development and production status.

Additional Information Relating to Reserves Data  

 Undeveloped Reserves Attributed in Current Year  The following discussion generally describes the basis on which Coastal attributes proved and probable undeveloped reserves and its plans for developing those undeveloped reserves.  Undeveloped reserves are those reserves expected to be recovered from known accumulations where a significant expenditure (e.g., the cost of drilling a well or initiating a waterflood project) is required to render them capable of production and which fully meet the requirements of the reserves category (proved or probable) to which they are assigned.  i) Proved Undeveloped Reserves  Proved undeveloped Reserves are generally those reserves related to discoveries that are commercial that have not yet been developed, infill drilling locations and recovery from waterflood projects prior to production response. All proved undeveloped reserves are planned to be developed in 2012 and 2013.  The following table summarizes the Company’s proved undeveloped Reserves that were first attributed in each of the most recent three financial years from the effective date of the Reserves Report and, in aggregate, before that time using forecast price and cost assumptions by production type.

ii) Probable Undeveloped Reserves  Probable undeveloped reserves are generally those reserves tested or indicated by analogy to be productive infill drilling locations and lands contiguous to production or production attributable to higher recovery rates. All probable undeveloped reserves are planned to be developed in 2012 and 2013.  The following table summarizes the Company’s probable undeveloped reserves that were first attributed in each of the most recent three financial years from the effective date of the Reserves Report and, in aggregate before that time using forecast price and cost assumptions by production type.

Significant Factors or Uncertainties Affecting Reserves Data  The process of estimating reserves is complex. Although every reasonable effort is made to ensure that reserve estimates are accurate, reserve estimation is an inferential science. It requires significant judgments and decisions based on available geological, geophysical, engineering, and economic data.  These estimates may change substantially as additional data from ongoing development activities and production performance becomes available and as economic conditions impacting oil and natural gas prices and costs change. Estimates are reviewed and revised, either upward or downward, as warranted by newly acquired information. The evaluation and drilling of hydrocarbon targets may be curtailed, delayed or cancelled by the unavailability or prevailing cost of drilling rigs or technical contractors, mechanical difficulties, adverse weather and ocean conditions, environmental issues, political or social unrest, technical hazards, such as unusual or unexpected formations or pressures or because of issues related to compliance with government regulations or requirements. Drilling may result in unprofitable efforts, not only with respect to dry wells, but also with respect to wells which, though yielding some hydrocarbons, are not sufficiently productive to economically justify commercial development. Furthermore, the successful completion of a well does not assure a profit on investment or the recovery of drilling, completion and operating costs. The reserve estimates provided by RPS that are contained herein were based on production forecasts, prices, and economic conditions applicable, as at December 31, 2011.  Future Development Costs  The following table provides a summary of the development costs during the next five years deducted in the estimation of future net revenue attributable to each of the reserves categories set out below:

   Based on forecast prices, Coastal estimates that its internally generated cash flow will be sufficient to fund the future development costs disclosed above. Coastal typically has available three sources of funding to finance its capital expenditure program: (i) internally generated cash flow from operations; (ii) debt financing when appropriate; and (iii) new equity issues, if available on favourable terms. Coastal does not expect that the costs of funding its capital expenditures will have a material effect on the economic viability of the development of any of its properties.

The following table summarizes the location of the Company’s interests as at December 31, 2011 in crude oil wells that are producing or that the Company considers to be capable of production.

 

Location Working Interest  

Block G5/43 Gulf of Thailand 100%

  

Coastal has 100% working interest and operatorship in its offshore properties. The Company leases a majority of its offshore infrastructure, which is reflected in lease operating expenses. The Company plans to purchase processing facilities which are currently leased, the acquisition costs are included in the analysis.

 Coastal’s wells to which reserves have been attributed and which are capable of producing but are not currently producing are provided in the table below. The offshore wells that are not producing were classified as shut-in because the wells had been drilled and were awaiting completion, which occurred in January and February of 2012.

The Company does not have any relinquishment requirements in the next twelve months. The Company has an obligation to drill one exploratory well on its G5/50 acreage before December 31, 2012.  In 2011, Coastal’s realized average price for crude oil was $101.39/bbl and APICO’s realized price for natural gas was $8..96/Mcf. In 2010, Coastal’s realized average price for crude oil was $54.06/bbl and APICO’s realized price for natural gas was $7.07/Mcf.  Coastal’s crude oil production is sold to credit worthy counterparties under contracts based on the Dubai benchmark price. APICO’s natural gas production is sold to PTT Public Company Ltd. under a gas sales agreement expiring in 2021.  Crude oil is stored in floating storage tankers until it is offloaded by the buyer. Natural gas is transported through pipelines in the Kingdom of Thailand.

 

The key risks and uncertainties associated with the Company’s unproved properties include the risk that no commercial quantities of hydrocarbons may be discovered in the area before the exploration license expires, or the risk that in the event of a discovery, commodity prices render the discovery uneconomical at the time.  Forward Contracts  From time to time, Coastal may enter into hedging arrangements to mitigate commodity price risk and take advantage of opportunistic pricing. Coastal has a Hedging Committee comprised of three independent directors that reviews all hedging transactions prior to entry. As of March 27, 2012, the Company has hedges covering 0.42 million barrels of net production through September 2012 at a fixed price of $79.03 per barrel. The Company also has a costless collar in place covering an additional 0.67 million barrels with a floor price of $70.00 per barrel and a ceiling price of $119.10 per barrel. The reference instrument for the Company’s commodity hedging transactions is currently ICE Brent crude.  Additional Information Concerning Abandonment and Reclamation Costs  Coastal is required to remove production equipment and to restore land at the end of oil and natural gas operations. The Company estimates these costs in accordance with existing laws, contracts, and other policies. These obligations are initially measured at fair value, which is the discounted future value of the liability. This fair value is also capitalized as part of the cost of the related assets and amortized over the useful life of the assets. The Company expects to incur abandonment and reclamation costs on approximately 42 net wells over the course of developing its Proved and Probable Reserves. Asset retirement obligation (“ARO”) cost calculations were derived from management’s estimates and typical industry experience and practices. The deemed ARO liability for Coastal’s well sites and facilities is the sum of the calculated abandonment and reclamation liabilities adjusted for designated status as an active, inactive, abandoned, or problem site. An inflation rate of 2% was used in the fair value calculation.

Total asset retirement cost calculated as of December 31, 2011 is estimated to be $55.4 million or $12.0 million when discounted at 10%. All of these costs have been deducted in estimating future net revenue. The Company expects to incur less than $0.5 million of ARO costs between 2012 and 2016.  Tax Horizon  Coastal has approximately $135.5 million in tax pools to apply against taxable income. Based upon planned capital expenditure programs and current commodity price assumptions, it is anticipated the Company will incur cash taxes of between 5 – 10% of operating cash flow under its current 2P production forecast.  Capital Expenditures  In 2011, Coastal incurred approximately $153.5 million of capital costs in total.  In 2011, Coastal’s share of APICO’s capital costs was $4.8 million, which is comprised of exploration costs for unproved properties as well as 3D seismic acquisition costs.

Exploration and Development Activities  As of December 31, 2011, the Company had drilled thirty three development wells, seven injection wells and eleven exploration wells in the Gulf of Thailand. It had participated in drilling four development wells and three exploratory wells (all three were dry holes) onshore Thailand. In 2012, the Company expects to continue to focus its resources in the Gulf of Thailand. Coastal’s overall objective for 2012 is to focus primarily on exploration and development activities and the advancement of reserves from the proved undeveloped and probable categories to the proved producing classification. Coastal has plans for 2012 to drill exploratory wells on several of its prospects. It is intended that Coastal’s capital program will be financed using cash flow from operations and will be adjusted on an ongoing basis to reflect operating results.
