Nebraska Administrative Code › Topic - OIL AND GAS CONSERVATION COMMISSION › Title 267 - NEBRASKA OIL AND GAS CONSERVATION COMMISSION › Chapter 4 - UNDERGROUND INJECTION › Section 267-4-004 - APPLICATION FOR APPROVAL OF ENHANCED RECOVERY INJECTION AND DISPOSAL WELLS

Current through June 17, 2024
004.01 Each application for the approval of a
				new enhanced recovery injection well or disposal well shall be filed and
				verified by a duly authorized representative of the operator. The original and
				six (6) copies of the application and one (1) complete set of attachments shall
				be furnished containing all the information required by these rules. More than
				one (1) well may be included on an application, provided, that such wells are
				associated with a single project or unit operation. An application for the
				approval of injection wells which are a part of a proposed enhanced recovery
				project or unit may be consolidated with the application for the approval of
				the enhanced recovery project or unit.
004.02 The application for the initial
				approval of an enhanced recovery injection or disposal well or wells shall be
				accompanied by:
004.02A A plat map showing all
				wells, including dry, abandoned or drilling wells shall be properly located and
				designated on said plat. In the case of an operation conducted subject to a
				unit agreement, the area affected shall be the area subject to such agreement,
				or that area within one-half (1/2) mile of each injection well, whichever is
				the greater distance.
004.02B The
				names and addresses of each person owning a fee, leasehold, mineral or royalty
				interest within one-half (1/2) mile of each injection well or within the area
				required to be shown on the plat, whichever is the greater.
004.02C A full description of the particular
				operation for which approval is sought.
004.02D The names and addresses of the
				operator or operators of the project.
004.02E If the wells have been drilled, a
				copy of each completion report and any available electric or radioactivity
				logs.
004.02F A schematic diagram
				of each well showing:
004.02F1 The total depth
				or plug-back of the well.
004.02F2
				The depth of the injection or disposal interval.
004.02F3 The geological name of the injection
				or disposal zone.
004.02F4 A
				geologic description of the injection or disposal zone including the location
				and extent of any known faults or fracture systems.
004.02F5 The depths of the tops and bottoms
				of the casing and cement to be used in the well.
004.02F6 The size and specifications of the
				casing and tubing, and the setting depth and type of packer, if used.
004.02G Information showing that
				injection into the proposed zone will not initiate vertical fractures into or
				through the overlying strata which could enable the injected fluids or
				formation fluids to enter any fresh water strata.
004.02H Information that no unplugged wells
				exist which will allow the migration of the injected fluids or formation fluids
				to enter any fresh water strata.
004.02I Information regarding the fracture
				pressures of the injection zone and the overlying strata, including the source
				of such information.
004.02J
				Proposed operating data:
004.02J1 Maximum
				designed or proposed daily injection rates and injection pressures.
004.02J2 The source of any fluids to be
				injected.
004.02J3 Analysis of a
				representative sample of the fluids to be injected.
004.02J4 Analysis of fresh water from two or
				more freshwater wells within one mile of the proposed injection well showing
				the location of the wells and the dates the samples were collected, or a
				statement why samples were not submitted.
004.02J5 Geological name of the lowest
				freshwater zone, if known, and the depth to the base of the freshwater
				zone.
004.02J6 The vertical
				distance separating top of the injection zone and the base of the lowest
				freshwater strata.
