Pooling

Pooling is the combining of two or more tracts of land or mineral interests to form a single drilling or spacing unit, as required by state conservation regulations. Pooling ensures that each spacing unit has a sufficient tract size for a well, regardless of how the surface or mineral ownership is divided.

Types of pooling

Voluntary pooling: - Mineral owners agree to combine their interests - Terms negotiated between the parties - Formalized in a pooling agreement or designation

Compulsory (forced) pooling: - Ordered by a state regulatory agency (e.g., oil and gas conservation commission) - Used when voluntary agreement cannot be reached - Ensures that one holdout owner cannot prevent development of a spacing unit - Available in most oil and gas producing states

Spacing units: - State regulations establish minimum spacing between wells - Each well must have a designated spacing unit (e.g., 640 acres for horizontal wells) - Pooling combines tracts within the spacing unit

Effects of pooling: - Production from anywhere within the pooled unit is attributed to all tracts - Royalties are shared among mineral owners based on their proportionate acreage - All pooled interests share in production on a pro-rata basis - Lease terms (e.g., held by production) apply to the entire pooled unit

Distinction from unitization: - Pooling combines interests within a single spacing unit (usually one well) - Unitization combines multiple spacing units or leases for field-wide development
