Wyoming Administrative Code › Agency 055 - Oil and Gas Conservation Commission › Sub-Agency 0001 - General Agency, Board or Commission Rules › Chapter 4 - ENVIRONMENTAL RULES, INCLUDING UNDERGROUND INJECTION CONTROL PROGRAM RULES FOR ENHANCED RECOVERY AND DISPOSAL PROJECTS › Section 4-7 - Waterflooding and Other Recovery Operations

Current through July 13, 2024
(a) Waterflooding
				and other recovery operations involving the introduction of extraneous forms of
				energy into any pool, repressuring, cycling or recycling operations, including
				the extraction and separation of liquid hydrocarbons from natural gas in
				connection therewith, is permitted only upon order of the Commission, or upon
				approval of the Supervisor, obtained pursuant to an application therefore filed
				in accordance with Chapter 5, Rules of Practice and Procedure. This provision
				is applicable to wells which are proposed to be converted to injection; as well
				as new wells drilled solely for the purpose of underground injection. Orders
				authorizing existing injection wells shall remain valid unless revoked by the
				Commission for just cause. In addition, there is assessed an annual fee of
				seventy-five dollars ($75.00) on all enhanced recovery wells.
(b)
Injection Well Permits
. The
				applicant shall have the burden of demonstrating that the proposed injection
				operation will not endanger fresh water sources. Injection wells shall be cased
				and the casing cemented in such a manner that damage will not be caused to oil,
				gas, or fresh water sources.
(c) An
				application for injection shall contain:
(i)
				A plat showing the area involved together with the well(s) which includes
				drilling well(s) and dry and abandoned well(s) located thereon, all properly
				designated;
(ii) A list of all
				lease Operators or Owners and surface owners within a one-half (1/2) mile
				radius of the proposed injection well(s);
(iii) An affidavit showing that said lease
				Operators or Owners and surface owners within a one-half (1/2) mile radius have
				been provided a copy of the application for injection;
(iv) A full description of the particular
				operations for which approval is requested;
(v) The pools from which wells are producing
				or have produced;
(vi) The name,
				description, and depth of the pool or pools to be affected;
(vii) The log of the injection well(s), or
				such information with respect thereto as is available;
(viii) A description of the casing of the
				injection well, or the proposed casing program, and the proposed method for
				testing casing before use of the injection wells;
(ix) A statement as to the type of fluid to
				be used for injection, its sources, and the estimated amounts to be injected
				daily. The Commission's Form 17 (Water Analyses Report) illustrates the minimum
				parameters for which water must be analyzed. Other reporting formats which
				include this minimum information may be accepted;
(x) The average and maximum injection
				pressure;
(xi) Evidence and data to
				support a Commission finding that the proposed injection well will not initiate
				fractures through the overlying strata or confining zone which could enable the
				injection fluid or formation fluid to enter the fresh water strata;
(xii) Standard laboratory analyses of the
				water to be injected and the water in the formation into which fluid is being
				injected. The method of water analysis is subject to review by the Commission
				or the Supervisor;
(xiii) The name
				and address of the Owner/Operator;
(xiv) A reference to the Commission order
				exempting the aquifer that is to receive the fluid;
(xv) The applicant shall provide for a
				one-quarter (1/4) mile radius of investigation for mechanical conditions of all
				wells which have penetrated the injection zone surrounding a proposed injection
				well. Specifically known and documented geological features may limit the need
				to review all wells within a one-quarter (1/4) mile radius; and,
(xvi) The depth and areal extent of all
				usable fresh and potable water (USDW) underlying the area proposed for
				exemption.
