TITLE 16ECONOMIC REGULATION
PART 1RAILROAD COMMISSION OF TEXAS
CHAPTER 3OIL AND GAS DIVISION
RULE §3.86Horizontal Drainhole Wells

      (iii) all owners of unleased mineral interests where there is no designated operator or lessee.

    (C) In the event the applicant is unable after due diligence to locate the whereabouts of any person to whom notice is required by this subsection, the applicant shall publish notice of this application pursuant to Chapter 1 of this title (relating to Practice and Procedure).

    (D) If any mineral owner of an offsite tract objects to the location of the penetration point, the applicant may request a hearing to demonstrate the necessity of the location of the penetration point of the well to prevent waste or to protect correlative rights.

    (E) If any person specified in subparagraph (B) of this paragraph did not receive notice as required in subparagraph (A) of this paragraph, that person may request a hearing. If the Commission determines at a hearing that the applicant did not provide the notice as required by subparagraph (A) of this paragraph, the Commission may cancel the permit.

    (F) To mitigate the potential for wellbore collisions, the applicant shall provide copies of any directional surveys to the parties entitled to notice under this section, upon request, within 15 days of the applicant's receipt of a request.

  (2) Drilling unit plat. The application to drill a horizontal drainhole shall be accompanied by a plat as required by §3.5(h) of this title (relating to Application to Drill, Deepen, Reenter, or Plug Back).

    (A) For fields that require a proration unit plat, in addition to the plat requirements provided for in §3.5(h) of this title, the plat shall include the lease, pooled unit or unitized tract, showing the acreage assigned to the drilling unit for the proposed well and the acreage assigned to the drilling units for all current applied for, permitted, or completed oil, gas, or oil and gas wells on the lease, pooled unit, or unitized tract.

    (B) An amended drilling permit application and plat shall be filed after completion of the horizontal drainhole well if the Commission determines that the drainhole as drilled is not reasonable with respect to the drainhole represented on the plat filed with the drilling permit application. A horizontal drainhole, as drilled, shall be considered reasonable with respect to the drainhole represented on the plat filed with the drilling permit application if the take points on the as-drilled plat comply with subsection (b)(4) and (5) of this section and with any applicable lease line spacing rules.

  (3) Directional survey. A directional survey from the surface to the farthest point drilled on the horizontal drainhole shall be required for all horizontal drainholes. The directional survey and accompanying reports shall be conducted and filed in accordance with §3.11 and §3.12 of this title (relating to Inclination and Directional Surveys Required, and Directional Survey Company Report, respectively). No allowable shall be assigned to any horizontal drainhole well until an acceptable directional survey and survey plat has been filed with the Commission.

  (4) Proration unit plat. The required proration unit plat must depict the lease, pooled unit, or unitized tract, showing the acreage assigned to the proration unit for the horizontal drainhole well, the acreage assigned to the proration units for all wells on the lease, pooled unit, or unitized tact, and the path, penetration point, take points, and terminus of all drainholes. No allowable shall be assigned to any horizontal drainhole well until an acceptable proration unit plat has been filed with the Commission. Proration unit plats are not required for wells in a designated UFT field. However, an operator of a well in a designated UFT field may file a proration unit plat along with Form P-16. Designated UFT fields have no maximum diagonal limit.

  (5) As-drilled plat. An as-drilled plat is required for each horizontal drainhole well. The as-drilled plat for each horizontal drainhole well shall show the surface location, actual wellbore path, penetration point, terminus, and first and last take points of the horizontal drainhole. If the drilling permit for the horizontal drainhole well is approved with one or more NPZs, the as-drilled plat shall show the nearest take point on either side of each NPZ.

  (6) Plat requirements. All plats required by this section shall be prepared using blue or black ink and shall include a certification by a professional land surveyor registered in accordance with Texas Occupations Code, Chapter 1071, relating to Land Surveyors, or by a registered professional engineer registered in accordance with Texas Occupations Code, Chapter 1001, relating to Professional Engineers.

(h) Exceptions and procedure for obtaining exceptions.

  (1) The Commission may grant exceptions to this section in order to prevent waste, prevent confiscation, or to protect correlative rights.

  (2) If a permit to drill a horizontal drainhole requires an exception to this section, the notice and opportunity for hearing procedures for obtaining exceptions to the density provisions prescribed in §3.38 of this title shall be followed as set forth in §3.38(h) of this title.

  (3) For notice purposes, the Commission presumes that for each adjacent tract and each tract nearer to any point along the proposed or existing horizontal drainhole than the prescribed minimum lease-line spacing distance, affected persons include:

    (A) the designated operator;

    (B) all lessees of record for tracts that have no designated operator; and

    (C) all owners of record of unleased mineral interests.

(i) UFT field designation criteria, application and approval procedures.

  (1) Criteria for UFT field designation.

    (A) Administrative UFT field designation. To be designated administratively as a UFT field, a field shall have the following characteristics:

      (i) the in situ permeability of at least one distinct producible interval within the field is 0.1 millidarcies or less prior to hydraulic fracture treatment, as determined by core data or other supporting data and analysis; and

      (ii) as to producing wells for which the Commission issued the initial drilling permit on or after February 1, 2012, that have been completed in the field, either:

        (I) there are at least five such wells of which at least 65% were drilled horizontally and completed using hydraulic fracture treatment; or

        (II) there are at least twenty-five such wells drilled horizontally and completed using hydraulic fracture treatment.

    (B) Alternative UFT field designation obtained through evidentiary hearing. If an applicant demonstrates in a hearing that reservoir characteristics exist other than the characteristics specified in subparagraph (A) of this paragraph such that horizontal drilling and hydraulic fracture treatment must be used in order to recover the resources from all or a part of the field and that UFT field designation will promote orderly development of the field, the hearings examiner may recommend to the Commission that the field be designated as a UFT field.

  (2) Procedures for UFT field designation.

    (A) Commission motion to designate a UFT field. The Commission may on its own motion propose that a field be designated as a UFT field upon written notice of the motion to all operators in the field.

      (i) If no written objection is filed within 21 days after the date the notice is issued, Commission staff may present a recommendation to the Commission regarding designation of the field as a UFT field.

      (ii) If the Commission receives a timely filed written objection, the Commission shall notify the operators in the field that an objection was received and allow any operator in the field 21 days to request a hearing. Pursuant to paragraph (1)(B) of this subsection, the operator requesting the hearing shall bear the burden of proof at the hearing. If no request to set the matter for hearing is received from an operator in the field, the Commission may either dismiss the matter or set the matter for hearing on its own motion. If the matter is set for hearing on the Commission's motion, the proponents of UFT field designation shall bear the burden of proof.

    (B) Operator application for UFT designation.

      (i) An operator may propose that a field be designated as a UFT field by submitting an application to the Commission that includes an affirmative statement that the field qualifies for designation as a UFT field and providing core data or other supporting data and analysis in support of that affirmative statement.
