Wyoming Administrative Code › Agency 055 - Oil and Gas Conservation Commission › Sub-Agency 0001 - General Agency, Board or Commission Rules › Chapter 3 - OPERATIONAL RULES, DRILLING RULES › Section 3-45 - Well Stimulation

Current through July 13, 2024
(a) An approved
				Application for Permit to Drill (APD, Form 1) or an approved Sundry Notice
				(Form 4) is required prior to the initiation of any well stimulation activity.
				Additional stimulation fluid information shall be provided to the Commission as
				an addendum to the APD (Form 1), or as part of a comprehensive
				drilling/completion/recompletion plan, or on a Sundry Notice (Form 4). A
				federal fieldwide development document or similar document may be accepted by
				the Supervisor. The Supervisor may require, prior to the well stimulation, the
				Owner or Operator to perform a suitable mechanical integrity test of the casing
				or of the casing-tubing annulus or other mechanical integrity test methods
				using procedures set forth in Chapter 2, Section 6 and Chapter 4, Section
				7(e)(i).
(b) Where multiple
				stimulation activities will be undertaken for several wells proposed to be
				drilled to the same zone(s) within an area of geologic similarity, approval may
				be sought from the Supervisor to accept a comprehensive master
				drilling/completion/recompletion plan containing the information required. The
				approved master drilling/completion/recompletion plan will then be referenced
				on each individual well's Application for Permit to Drill (Form 1).
(c) The Owner or Operator shall provide
				geological names, geological description and depth of the formation into which
				well stimulation fluids are to be injected.
(d) The Owner or Operator shall provide
				detailed information to the Supervisor as to the base stimulation fluid source.
				The Owner or Operator or service company shall provide to the Supervisor, for
				each stage of the well stimulation program, the chemical additives, compounds
				and concentrations or rates
proposed
to be mixed and
				injected, including:
(i) Stimulation fluid
				identified by additive type (such as but not limited to acid, biocide, breaker,
				brine, corrosion inhibitor, crosslinker, demulsifier, friction reducer, gel,
				iron control, oxygen scavenger, pH adjusting agent, proppant, scale inhibitor,
				surfactant);
(ii) The chemical
				compound name and Chemical Abstracts Service (CAS) number shall be identified
				(such as the additive biocide is glutaraldehyde, or the additive breaker is
				aluminum persulfate, or the proppant is silica or quartz sand, and so on for
				each additive used);
(iii) The
				proposed rate or concentration for each additive shall be provided (such as gel
				as pounds per thousand gallons, or biocide at gallons per thousand gallons, or
				proppant at pounds per gallon, or expressed as percent by weight or percent by
				volume, or parts per million, or parts per billion);
(iv) The Owner or Operator or service company
				may also provide a copy of the contractor's proposed well stimulation program
				design including the above detail;
(v) The Supervisor may request additional
				information under this subsection prior to the approval of the Application for
				Permit to Drill (Form 1) or of the Sundry Notice (Form 4);
(vi) The Supervisor retains discretion to
				request from the Owner or Operator and/or the service company, the formulary
				disclosure for the chemical compounds used in the well
				stimulation(s).
