House Bill 1909 In August 2010, Commissioner Murphy assembled a group of stakeholders to come up with a solution to fully develop the Shale Reservoirs. The group found that the OCC was constrained in its ability to adequately protect the correlative rights, prevent of waste and promote the full development of these Oklahoma resources because of the limitations placed upon it by the existing statutory scheme. Advances in horizontal drilling techniques for wells drilled and completed in shale reservoirs (i.e., Woodford) advanced beyond the historical statutory spacing scheme, in particular with laterals exceeding 5,280 feet in length. Beginning in August 2010, the working group met eight (8) times, usually for three (3) hours per meeting, with the participants collectively investing hundreds of hours in discussing, drafting and re-drafting the Act.

2011 Shale Reservoir Development Act House Bill 1909 – April 13, 2011
20
2011 Shale Reservoir Development Act
The Act is not the same 1,280-acre drilling and spacing unit bills that royalty owners have opposed in prior years. The Act is a comprehensive piece of legislation to promote development of shale reservoirs and is limited to shale reservoirs. Aid in preventing waste and protecting the correlative rights of the owners of oil and gas rights. Harmonize Oklahoma’s historical oil and gas law with the expanding technology of drilling and completing horizontal wells in shale reservoirs, including the use of horizontal laterals of over one mile long.
21
2011 Shale Reservoir Development Act
Mineral Owner Organizations supported the Act Coalition of Oklahoma Surface and Mineral Owners (COSMO) OK-NARO (National Association of Royalty Owners) Oklahoma Mineral Owners Association (OMOA) Farmers Royalty Company (one of Oklahoma’s oldest, largest and most active royalty companies) The Act creates two new tools for the development of the Shale Reservoir Multiunit Horizontal Wells (similar to Arkansas approach) A new hybrid Unitization (similar to enhanced or secondary recovery units)
22
2011 Shale Reservoir Development Act
Allows drilling of horizontal wells in shale reservoirs across existing unit boundaries (i.e., across two or more existing 640-acre units). These wells are called “multiunit horizontal wells.” The drilling & production costs, the oil and gas production and the sales proceeds will be allocated to each of the affected units in a manner to protect the correlative rights of parties in each unit. The default allocation is a proration between the units based upon the feet of perforations in each of the units.
23
2011 Shale Reservoir Development Act
The portion of the completed horizontal lateral in each unit will be treated as a separate well for that unit. The application and notice of hearing must be served on all owners who have a right to share in proceeds from the affected units.
24
2011 Shale Reservoir Development Act Definitions
Shale Reservoir – a common source of supply which is a shale formation that is so designated by the Oklahoma Corporation Commission through rule or order and shall include any associated common source of supply. Associated Common Source of Supply – a common source of supply which is immediately adjoining the shale common source of supply which is inadvertently encountered in the drilling of the lateral of a multiunit horizontal well.

26
2011 Shale Reservoir Development Act Pooling
Pooling – The Commission may require the owners to pool their interests in each affected unit as to the development involving the multiunit horizontal well. Prior Pooling – If the Commission has previously pooled the interest of owners in an affected unit in which a multiunit horizontal well is proposed, the Commission may amend the pooling order to the extent necessary to have the pooling order cover the development involving the multiunit horizontal well.
27
2011 Shale Reservoir Development Act Definitions
Allocation Factor – the percentage of costs, production or proceeds allocated to a unit affected by a multiunit horizontal well. The allocation factor for each affected unit shall be determined by dividing the length of the completion interval located within the affected unit by the entire length of the completion interval in the subject multiunit horizontal well.

Multiunit Horizontal Well Application
Applicant anticipates that approximately 50% of the completion interval of such multiunit horizontal well will be located in Section 28 and approximately 50% of such completion interval will be located in Section 33, with the cost of an the production and proceeds from such multiunit horizontal to be allocated between the affected units. NYSE: DVN
35
Multiunit Horizontal Well Application
Participants pay drilling and completion costs based upon the proposed allocation. After well is drilled the allocation is adjusted based upon the actual number of perforated lateral in each section. NYSE: DVN

2011 Shale Reservoir Development Act Horizontal Well Unitization for Shale Reservoirs
Is a hybrid concept between a drilling and spacing unit and a unitization (secondary recovery). Each unit shall be two governmental sections. 1280 acre unitization OCC may expand to four sections if necessary to prevent waste, to protect correlative rights and will result in increased recovery of substantially more oil and gas.

Proposed Legislation Multiunit wells in other formations
2013, 2014, Proposed legislation that would allow the use of multiunit horizontal wells in “targeted reservoirs”, not just shale reservoirs. Targeted reservoirs is any common source of supply which has been determined by the OCC that is appropriately suited for development through a multiunit horizontal well. 2016? NYSE: DVN
