Section 122-17-004 - Specific Requirements for Mineral Production Wells

004.02A. Depth to the production zone;

004.02B. External pressure, internal pressure, axial loading, etc.;

004.02C. Hole size;

004.02D. Size and grade of all casing strings (wall thickness, diameter, nominal weight, length, joint specification, and construction material);

004.02E. Corrosiveness of production fluids and formation fluids or combination thereof;

004.02F. Lithology of production and confining zones; and

004.02G. Type and grade of cement.

004.03A Appropriate logs and other tests shall be conducted during the drilling and construction of new mineral production wells. A descriptive report interpreting the results of such logs and tests shall be prepared by a qualified log analyst and submitted to the Director. The logs and tests appropriate to each type of mineral production well shall be determined based on the intended function, depth, construction and other characteristics of the well, availability of similar data in the area of the drilling site and the need for additional information that may arise from time to time as the construction of the well progresses. At a minimum, such logs and tests shall include deviation checks conducted on all holes where pilot holes and reaming are used, at sufficiently frequent intervals to assure that vertical avenues for fluid migration in the form of diverging holes are not created during drilling.
