The space between the mineral or sand grains is called the pore space. Pore space can also be the space in fractures and voids in a rock body.
To explain this further one can relate to a jar of rocks. Although each individual rock touches many others, there is still enough space in between the rocks to be filled with sand – this is referred to as pore space.
The authorization to conduct activities in freehold mineral rights is by private agreement with the freehold mineral rights owner. The Crown only requires indemnification for use of Crown pore space for the purpose of injecting or disposing into freehold mineral rights.
At the time of the well licence application, the licensee will need to include proof of indemnification together with their well licence to the Alberta Energy Regulator (AER). Send the original letter of indemnification to Alberta Energy and a copy will go to the AER with the well licence application. Indemnification Letter template in PDF
In general, road allowances are undisposed Crown land. Your P&NG lease or license does not include the rights to any road allowance that lies adjacent to the sections of land contained in your agreement.
By policy only, road allowances within units are treated as part of the unit. Tract factors have already been negotiated for the unitized area and allow for the allocation of production and costs. The department allows you to access the road allowance to test or produce your unitized zones without permission.
A company is allowed to drill a maximum of 15 metres beyond their leased rights, in accordance with the Alberta Energy Regulator (AER) Guide 56. This is only to set logging tools, so that information can be obtained down to the base of the leased zones, although you cannot produce from the over hole portion of the wellbore.
Applications for additional over hole must be supported by geological data with substantive (non-economic) reasons for the additional depth required. Logging tools were developed to fit into the 15 metre allowable over hole and with these tools the geological contacts can be imaged.
Any use of Crown undisposed mineral rights requires prior approval from the department. You would be required to submit technical data, such as geological or engineering data, to the Crown to demonstrate that the proposed zone for disposal/injection is non-hydrocarbon bearing. If you intend to use a vested well, permission is also required to use the wellbore. You would also need to follow the Regulations of the AER.
Approval is not required if injection of carbon dioxide (CO2) is part of normal oil and gas operations and is conducted on Crown leased mineral rights. However, if injection occurs on Crown undisposed rights pre-approval is required (refer to previous question)
A carbon capture and storage (CCS) permit or lease is required if the operation is to capture CO2 from large industrial sources and inject it into selected deep underground formations for long-term storage. Additional carbon capture and storage information is available on this website.
No prior approval is required if the zone is leased as to one of the substances in which you wish to conduct operations. Note: Prior approval is required if the Crown rights are entirely undisposed. Crown Mineral Activity Applications/Authorizations (previously known as Well Authorizations) are now available through ETS. Please review the Online Learning modules for details.
