CONTINGENT RESOURCES
Those quantities of petroleum estimated, as of a given date, to be potentially recoverable from known
accumulations by application of development projects, but which are not currently considered to be
commercially recoverable due to one or more contingencies.
Contingent Resources may include, for example, projects for which there are currently no viable markets, or
where commercial recovery is dependent on technology under development, or where evaluation of the
accumulation is insufficient to clearly assess commerciality. Contingent Resources are further categorized in
accordance with the level of certainty associated with the estimates and may be sub-classified based on project
maturity and/or characterized by their economic status.
Development Pending
A discovered accumulation where project activities are ongoing to justify commercial development in the
foreseeable future.
The project is seen to have reasonable potential for eventual commercial development, to the extent that
further data acquisition (e.g. drilling, seismic data) and/or evaluations are currently ongoing with a view to
confirming that the project is commercially viable and providing the basis for selection of an appropriate
development plan. The critical contingencies have been identified and are reasonably expected to be
resolved within a reasonable time frame. Note that disappointing appraisal/evaluation results could lead to a
re-classification of the project to
“
On Hold
”
or
“
Not Viable
”
status. The project
“
decision gate
”
is the decision
to undertake further data acquisition and/or studies designed to move the project to a level of technical and
commercial maturity at which a decision can be made to proceed with development and production.
Development Unclarified or on Hold
A discovered accumulation where project activities are on hold and/or where justification as a commercial
development may be subject to significant delay.
The project is seen to have potential for eventual commercial development, but further appraisal/evaluation
activities are on hold pending the removal of significant contingencies external to the project, or substantial
further appraisal/evaluation activities are required to clarify the potential for eventual commercial
development. Development may be subject to a significant time delay. Note that a change in circumstances,
such that there is no longer a reasonable expectation that a critical contingency can be removed in the
foreseeable future, for example, could lead to a reclassification of the project to
“
Not Viable
”
status. The
project
“
decision gate
”
is the decision to either proceed with additional evaluation designed to clarify the
potential for eventual commercial development or to temporarily suspend or delay further activities pending
resolution of external contingencies.
Development Not Viable
A discovered accumulation for which there are no current plans to develop or to acquire additional data at the
time due to limited production potential.
The project is not seen to have potential for eventual commercial development at the time of reporting, but
the theoretically recoverable quantities are recorded so that the potential opportunity will be recognized in the
event of a major change in technology or commercial conditions. The project
“
decision gate
”
is the decision
not to undertake any further data acquisition or studies on the project for the foreseeable future.
