Current through Register Vol. 54, No. 50, December 14, 2024
Section 78.72 - Use of safety devices-blow-out prevention equipment(a) The operator shall use blow-out prevention equipment after setting casing with a competent casing seat in the following circumstances: (1) When drilling out solid core hydraulic fracturing plugs to complete a well.(2) When well head pressures or natural open flows are anticipated at the well site that may result in a loss of well control.(3) When the operator is drilling in an area where there is no prior knowledge of the pressures or natural open flows to be encountered.(4) On wells regulated by the Oil and Gas Conservation Law (58 P.S. §§ 401-419).(5) When drilling within 200 feet of a building.(b) Blow-out prevention equipment used must be in good working condition at all times.(c) Controls for the blow-out preventer shall be accessible to allow actuation of the equipment. Additional controls for a blow-out preventer with a pressure rating of greater than 3,000 psi, not associated with the rig hydraulic system, shall be located at least 50 feet away from the drilling rig so that the blow-out preventer can be actuated if control of the well is lost.(d) The operator shall use pipe fittings, valves and unions placed on or connected to the blow-out prevention systems that have a working pressure capability that exceeds the anticipated pressures.(e) The operator shall conduct a complete test of the ram type blow-out preventer and related equipment for both pressure and ram operation before placing it in service on the well. The operator shall test the annular type blow-out preventer in accordance with the manufacturer's published instructions, or the instructions of a professional engineer, prior to the device being placed in service. Blow-out prevention equipment that fails the test may not be used until it is repaired and passes the test.(f) When the equipment is in service, the operator shall visually inspect blow-out prevention equipment during each tour of drilling operation and during actual drilling operations test the pipe rams for closure daily and the blind rams for closure on each round trip. When more than one round trip is made in a day, one daily closure test for blind rams is sufficient. Testing shall be conducted in accordance with American Petroleum Institute publication API RP53, "API Recommended Practice for Blowout Prevention Equipment Systems for Drilling Wells," or other procedure approved by the Department. The operator shall record the results of the inspection and closure test in the drillers log before the end of the tour. If blow-out prevention equipment is not in good working order, drilling shall cease when cessation of drilling can be accomplished safely and not resume until the blow-out prevention equipment is repaired or replaced and retested.(g) All lines, valves and fittings between the closing unit and the blow-out preventer stack must be flame resistant and have a rated working pressure that meets or exceeds the requirements of the blow-out preventer system.(h) When a blowout preventer is installed or required under subsection (a), there shall be present on the well site an individual with a current certification from a well control course accredited by the International Association of Drilling Contractors or other organization approved by the Department. The certification shall be available for review at the well site. The Department will maintain a list of approved accrediting organizations on its web site.(i) Well drilling and completion operations requiring pressure barriers, as identified by the operator under § 78.55(b) (relating to control and disposal plan), shall employ at least two mechanical pressure barriers between the open producing formation and the atmosphere that are capable of being tested. The mechanical pressure barriers shall be tested according to manufacturer specifications prior to operation. If during the course of operations the operator only has one functioning barrier, operations must cease until additional barriers are added and tested or the redundant barrier is repaired and tested. Stripper rubber or a stripper head may not be considered a barrier.(j) The minimum amount of intermediate casing that is cemented to the surface to which blow-out prevention equipment may be attached, shall be in accordance with the following: | Proposed Total Vertical Depth (in feet) | Minimum Cemented Casing Required (in feet of casing cemented) |
| Up to 5,000 | 400 |
| 5,001 to 5,500 | 500 |
| 5,501 to 6,000 | 600 |
| 6,001 to 6,500 | 700 |
| 6,501 to 7,000 | 800 |
| 7,001 to 8,000 | 1,000 |
| 8,001 to 9,000 | 1,200 |
| 9,001 to 10,000 | 1,400 |
| Deeper than 10,000 | 1,800 |
(k) Upon completion of the drilling operations at a well, the operator shall install and utilize equipment, such as a shut-off valve of sufficient rating to contain anticipated pressure, lubricator or similar device, as may be necessary to enable the well to be effectively shut-in while logging and servicing the well and after completion of the well.The provisions of this § 78.72 adopted July 28, 1989, effective 7/29/1989, 19 Pa.B. 3229; amended February 4, 2011, effective 2/5/2011, 41 Pa.B. 805; amended October 7, 2016, effective 10/8/2016, 46 Pa.B. 6431.The provisions of this § 78a.72 amended under 58 Pa.C.S. §§ 3202, 3215(e), 3218(a), 3218.2(a)(4), 3218.4(c) and 3274; section 5 of The Clean Streams Law (35 P.S. § 691.5); section 105 of the Solid Waste Management Act (35 P.S. § 6018.105); section 5 of the Dam Safety and Encroachments Act (32 P.S. § 693.5); section 104 of the Land Recycling and Environmental Remediation Standards Act (35 P.S. § 6026.104); sections 301 and 302 of the Radiation Protection Act (35 P.S. §§ 7110.301 and 7110.302); section 3 of the Unconventional Well Report Act (58 P.S. § 1003); section 13.2 of the act of July 10, 2014 (P.L. 1053, No. 126) adding section 1741.1-E of The Fiscal Code (72 P.S. § 1741.1-E); and sections 1917-A and 1920-A of The Administrative Code of 1929 (71 P.S. §§ 510-17 and 510-20).
