Section 0400-52-08-.02 - INCLINATION SURVEYS

An inclination survey shall be made at the discretion of the Supervisor on all wells drilled with the first shot-point at a depth not greater than that of the surface casing seat and succeeding shot-points not more than 1,000 feet apart. Inclination surveys conforming to the requirements may be made either during the normal course of drilling or after the well has reached total depth. Such survey data shall be certified by the operator's representative and/or drilling contractor and shall indicate the resultant lateral deviation as the sum of the calculated lateral displacement determined between each inclination survey point, assuming that all such displacement occurs in the direction of the nearest property line. If a directional survey determining the bottom of the hole is filed with the Supervisor upon completion of the well, it shall not be necessary to furnish the inclination survey date. Except as otherwise specified herein, all inclination and/or directional survey data shall be filed along with Well History (Form CN-0221).
