SECTION 165:10-3-27. Deviation from the vertical

(a)   Well location for purposes of well spacing. For purposes of the well spacing requirements of 165:10-1-21 and 165:10-1-24, the location of a well in a common source of supply is the closest point to the unit boundary where the wellbore intersects the common source of supply.

(b)   Presumed bottom hole location. For purposes of review of Form 1000 applications, the Conservation Division may presume that the location in a common source of supply of a well without a horizontal drainhole is the same as the surface location for the well unless:

(1)   The operator submits a bottom hole survey, if the well has been drilled; or

(2)   The operator complies with (c)(1) of this Section.

(c)   Permitted and prohibited locations.

(1)   Offpattern surface location; permitted subsurface location.

(A)   The Conservation Division may approve a Form 1000 for a well to be commenced without a location exception at an offpattern surface location for a common source of supply when:

(i)   The Form 1000 lists a subsurface location which is a permitted location for the common source of supply.

(ii)   Issuance of a Permit to Drill is conditioned on the operator running a bottom hole survey within 30 days after reaching total depth and on the operator submitting the survey to the Conservation Division within 45 days after the well reaches total depth.

(B)   The well shall not receive an allowable for the common source of supply until a bottom hole survey shows that the well is at a permitted location or until the operator obtains a location exception order for the subsurface location.

(2)   Offpattern subsurface location.

(A)   The Conservation Division shall not approve a Form 1000 without a location exception order for an offpattern subsurface location.

(B)   Issuance of a Permit to Drill under (1) of this subsection does not permit an operator to have, without a location exception order, an offpattern subsurface location for a common source of supply.

(d)   Required directional and bottom hole surveys. For good cause, the Commission may order an operator to run directional and/or bottom-hole surveys for a common source of supply in a well:

(1)   Upon application, notice, and hearing; or

(2)   In any case involving the location of a well, upon motion of an affected party or upon the Commission's own motion.
