Caution Respecting Reserves Information
The determination of oil and natural gas reserves involves the preparation of estimates that have an inherent degree of associated uncertainty. Categories of Proved, Probable and Possible reserves have been established to reflect the level of these uncertainties and to provide an indication of the probability of recovery. The estimation and classification of reserves requires the application of professional judgement combined with geological and engineering knowledge to assess whether or not specific reserves classification criteria have been satisfied. Knowledge of concepts including uncertainty and risk, probability and statistics, and deterministic and probabilistic estimation methods is required to properly use and apply reserves definitions.
The recovery and reserve estimates of natural gas liquids and natural gas reserves provided herein are estimates only. Actual reserves may be greater than or less than the estimates provided herein. The estimated future net revenue from the production of the disclosed natural gas reserves, whether calculated without discount or using a discount rate, does not represent the fair market value of these reserves. Estimates of reserves and future net revenue for individual properties may not reflect the same confidence level as estimates of reserves and future net revenue for all properties, due to the effects of aggregation.
Information Regarding Reserves
Reserves are estimated remaining quantities of commercially recoverable oil, 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 subclassified based on development and production status.
“ Proved reserves ” are 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 ” are 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 plus Probable reserves.
“ Possible reserves ” are those additional reserves that are less certain to be recovered than Probable reserves. It is unlikely that the actual remaining quantities recovered will exceed the sum of the estimated Proved plus Probable plus Possible reserves. There is a 10% probability that the quantities actually recovered will equal or exceed the sum of Proved plus Probable plus Possible reserves.
The qualitative certainty levels referred to in the definitions above are applicable to“individual reserves entities” (which refers to the lowest level at which reserves calculations are performed) and to“reported reserves” (which refers to the highest-level sum of individual entity estimates for which reserves estimates are presented). Reported reserves should target the following levels of certainty under a specific set of economic conditions:
- at least a 90% probability that the quantities actually recovered will equal or exceed the estimated Proved reserves; and at least a 50% probability that the quantities actually recovered will equal or exceed the sum of estimated Proved plus Probable reserves.
A qualitative measure of the certainty levels pertaining to estimates prepared for the various reserves categories is desirable to provide a clearer understanding of the associated risks and uncertainties. However, the majority of reserves estimates will be prepared using deterministic methods that do not provide a mathematically derived quantitative measure of probability. In principle, there should be no difference between estimates prepared using probabilistic or deterministic methods.
Each of the reserve categories (Proved and Probable) may be divided into developed and undeveloped categories as follows:
“ Developed Producing reserves ” are those reserves that are expected to be recovered from completion intervals open at the time of the estimate. These reserves may be currently producing or, if shut-in, they must have previously been on production, and the date of resumption of production must be known with reasonable certainty.
“ Developed Non-Producing reserves ” are those reserves that either have not been on production, or have previously been on production, but are shut-in, and the date of resumption of production is unknown.
“ Undeveloped reserves ” are those reserves expected to be recovered from known accumulations where a significant expenditure (e.g., when compared to the cost of drilling a well) is required to render them capable of production. They must fully meet the requirements of the reserves classification (Proved, Probable and Possible) to which they are assigned and expected to be developed within a limited time.
In multi-well pools it may be appropriate to allocate total pool reserves between the developed and undeveloped subclasses or to subdivide the developed reserves for the pool between developed producing and developed nonproducing. This allocation should be based on the estimator's assessment as to the reserves that will be recovered from specific wells, facilities and completion intervals in the pool and their respective development and production status.
Information Regarding Contingent Resources
“ Contingent Resources ” are those quantities of oil or natural gas estimated, as of a given date, to be potentially recoverable from known accumulations using established technology or technology under development but which are not currently considered to be commercially recoverable due to one or more contingencies.
Contingent Resources are further categorised according to the level of certainty associated with the estimates and may be sub-classified based on a project maturity and characterised by their economic status. There are three classifications of Contingent Resources: low estimate, best estimate and high estimate. Best estimate is a classification of estimated resources described in the COGE Handbook as the best estimate of the quantity that will be actually recovered; it is equally likely that the actual remaining quantities recovered will be greater or less than the best estimate. If probabilistic methods are used, there should be at least a 50% probability that the quantities actually recovered will equal or exceed the best estimate.
The project maturity subclasses include development pending, development on hold, development unclarified and development not viable. All of the Contingent Resources disclosed in this news release are classified as development pending. Development pending is defined as a contingent resource where resolution of the final conditions of development is being actively pursued. Chance of development is the likelihood that an accumulation will be commercially developed.
Conversion of the development pending Contingent Resources to reserves is dependent upon a final investment decision for the natural gas development of the Maria Conchita Block and the Sinú-9 Block.
There is no certainty that any portion of the Contingent Resources will be discovered. If discovered, there is no certainty that it will be commercially viable to produce any portion of the Contingent Resources.
Information Regarding Prospective Resources
This news release discloses estimates of the Company's Prospective Resources. There is no certainty that it will be commercially viable to produce any portion of such Prospective Resources. Estimates of Prospective Resources involve additional risks over estimates of reserves. The accuracy of any resources estimate is a function of the quality and quantity of available data and of engineering interpretation and judgment. While resources presented herein are considered reasonable, the estimates should be accepted with the understanding that reservoir performance subsequent to the date of the estimate may justify revision, either upward or downward.
“ Prospective Resources ” are defined in the COGE Handbook as those quantities of petroleum estimated, as of a given date, to be potentially recoverable from undiscovered accumulations by application of future development projects. Prospective Resources have both an associated chance of discovery and a chance of development. The chance that an exploration project will result in the discovery of petroleum is referred to as the chance of discovery. The chance that an accumulation will be commercially developed is referred to as the chance of development
Prospective Resources are further subdivided in accordance with the level of certainty associated with recoverable estimates assuming their discovery:
- Low Estimate : This is considered to be a conservative estimate of the quantity that will actually be recovered. It is likely that the actual remaining quantities recovered will exceed the low estimate. If probabilistic methods are used, there should be at least a 90% probability (P90) that the quantities actually recovered will equal or exceed the low estimate. Best Estimate : This is considered to be the best estimate of the quantity that will actually be recovered. It is equally likely that the actual remaining quantities recovered will be greater or less than the best estimate. If probabilistic methods are used, there should be at least a 50% probability (P50) that the quantities actually recovered will equal or exceed the best estimate. High Estimate : This is considered to be an optimistic estimate of the quantity that will actually be recovered. It is unlikely that the actual remaining quantities recovered will exceed the high estimate. If probabilistic methods are used, there should be at least a 10% probability (P10) that the quantities actually recovered will equal or exceed the high estimate.
Prospective Resources are not, and should not be confused with, reserves or Contingent Resources. "Prospective Resources" are those quantities of petroleum estimated, as of a given date, to be potentially recoverable from undiscovered accumulations by application of future development projects. Prospective Resources have both an associated chance of discovery and a chance of development.
There is no certainty that any portion of the Prospective Resources will be discovered. If discovered, there is no certainty that it will be commercially viable to produce any portion of the Prospective Resources or that the Company will produce any portion of the volumes currently classified as Prospective Resources.
The estimates of Prospective Resources involve implied assessment, based on certain estimates and assumptions, that the resources described exists in the quantities predicted or estimated, as at a given date, and that the resources can be profitably produced in the future. Actual Prospective Resources (and any volumes that may be reclassified as reserves) and future production therefrom may be greater than or less than the estimates provided herein.
Information Regarding Condensate
“Condensate” , also called“gas condensate”, or“natural gas liquids”, is a low-density mixture of hydrocarbon liquids that are present as gaseous components in the raw natural gas produced from many natural gas fields. Some natural gas species within the raw natural gas will condensate to a liquid state if the temperature is reduced to below the hydrocarbon dew point temperature at a set pressure. Raw natural gas may come from any one of three types of natural gas wells:
(a) Crude Oil Wells : Raw natural gas that comes from crude oil wells is called“associated gas”. This natural gas can exist separate from crude oil in the underground formation or be dissolved in the crude oil. Condensate produced from oil wells is often referred to as“lease condensate”;
(b) Dry Gas Wells : These wells typically produce only raw natural gas that contains no hydrocarbon liquids. Such natural gas is called“non-associated gas”. Condensate from dry natural gas is extracted at natural gas processing plants and is often called“plant condensate”; and
(c) Condensate Wells : These wells produce raw natural gas along with natural gas liquids. Such natural gas is also called“associated gas” and is often referred to as“wet gas”.
