2 OIL & GAS LEASES Leases are acquired by a landman whose primary duty is to secure leasehold interest from the landowners. County records are searched to determine ownership in a particular area. Not only must the landman determine who owns the land, but who owns the mineral rights as well. After this has been determined, the landman will negotiate the necessary leases with the landowners. Compensation in the form of a bonus, a delay rental payment, and royalty are typically offered the landowner in return for leasing the area of interest. Leases for gas and oil are legal contracts, which for specified compensation give the company the right to explore for and to extract oil and gas. Each lease is negotiated and agreed upon individually. 2

3 DRILLING UNIT DRILLING UNITS - WELL LOCATIONS. In the absence of an order by the commission setting spacing units for a pool: Vertical or directional oil wells projected to a depth not deeper than the Mission Canyon formation shall be drilled upon a governmental quarter section or equivalent lot, located not less than five hundred feet [152.4 meters] to the boundary. Vertical or directional oil wells projected to a depth deeper than the Mission Canyon formation shall be drilled on a governmental quarter section or equivalent lots, located not less than six hundred sixty feet [ meters] to the boundary of such governmental quarter section or equivalent lots. Horizontal wells with a horizontal displacement of the well bore drilled at an angle of at least eighty degrees within the productive formation of at least five hundred feet [152.4 meters], projected to a depth not deeper than the Mission Canyon formation, must be drilled upon a drilling unit described as a governmental section or described as two adjacent governmental quarter sections within the same section or equivalent lots, located not less than five hundred feet [152.4 meters] to the outside boundary of such tract. The horizontal well proposed to be drilled must, in the director s opinion, justify the creation of such drilling unit. No more than one well may be drilled to the same pool on any such tract, except by order of the commission. 3

6 100 years ago wells were drilled wherever they would fit (rule of capture), and were not spaced on the basis of geology and engineering as is currently done by the North Dakota Industrial Commission. This wasted a great deal of the oil and gas. 6

8 DRILLING APPLICATION FOR PERMIT TO DRILL Before any person shall begin any well-site preparation for the drilling of any well other than surveying and staking, such person shall file an application for permit to drill (form 1) with the director, together with a permit fee of one hundred dollars. The application must be accompanied by the bond pursuant to section or the applicant must have previously filed such bond with the commission, otherwise the application is incomplete. An incomplete application received by the commission has no standing and will not be deemed filed until it is completed. The application for permit to drill shall be accompanied by an accurate plat certified by a registered surveyor showing the location of the proposed well with reference to the nearest lines of a governmental section. The plat shall also include latitude and longitude of the proposed well location to the nearest tenth of a second. Information to be included in such application shall be the proposed depth to which the well will be drilled, estimated depth to the top of important markers, estimated depth to the top of objective horizons, the proposed mud program, the proposed casing program, including size and weight thereof, the depth at which each casing string is to be set, the proposed pad layout, including cut and fill diagrams, and the proposed amount of cement to be used, including the estimated top of cement. The director may impose such terms and conditions on the permits issued under this section as the director deems necessary. The director shall deny an application for a permit under this section if the proposal would cause, or tend to cause, waste or violate correlative rights. 8
