(1) Criteria for construction of
anthropogenic CO2 injection wells. This paragraph
establishes the criteria for the information about the construction and casing
and cementing of, and special equipment for, anthropogenic
CO2 injection wells that an applicant must include in an
application.
(A) General. The operator of a
geologic storage facility must ensure that all anthropogenic
CO2 injection wells are constructed and completed in a
manner that will:
(i) prevent the movement of
injected CO2 or displaced formation fluids into any
unauthorized zones or into any areas where they could endanger USDWs;
(ii) allow the use of appropriate testing
devices and workover tools; and
(iii) allow continuous monitoring of the
annulus space between the injection tubing and long string casing.
(B) Casing and cementing of
anthropogenic CO2 injection wells.
(i) The operator must ensure that injection
wells are cased and the casing cemented in compliance with §
3.13 of this title (relating to
Casing, Cementing, Drilling, Well Control, and Completion Requirements), in
addition to the requirements of this section.
(ii) Casing, cement, cement additives, and/or
other materials used in the construction of each injection well must have
sufficient structural strength and must be of sufficient quality and quantity
to maintain integrity over the design life of the injection well. All well
materials must be suitable for use with fluids with which the well materials
may be expected to come into contact and must meet or exceed test standards
developed for such materials by the American Petroleum Institute, ASTM
International, or comparable standards as approved by the director.
(iii) Surface casing must extend through the
base of the lowermost USDW above the injection zone and must be cemented to the
surface.
(iv) Circulation of cement
may be accomplished by staging. The director may approve an alternative method
of cementing in cases where the cement cannot be circulated to the surface,
provided the applicant can demonstrate by using logs that the cement does not
allow fluid movement between the casing and the well bore.
(v) At least one long string casing, using a
sufficient number of centralizers, must extend from the surface to the
injection zone and must be cemented by circulating cement to the surface in one
or more stages. The long string casing must isolate the injection zone and
other intervals as necessary for the protection of USDWs and to ensure
confinement of the injected and formation fluids to the permitted injection
zone using cement and/or other isolation techniques. If the long string casing
does not extend through the injection zone, another well string or liner must
be cemented through the injection zone (for example, a chrome liner).
(vi) The applicant must verify the integrity
and location of the cement using technology capable of radial evaluation of
cement quality and identification of the location of channels to ensure that
USDWs will not be endangered.
(vii)
The director may exempt existing Class II wells that have been associated with
injection of CO2 for the purpose of enhanced recovery,
Class V experimental technology wells, and stratigraphic test wells from
provisions of these casing and cementing requirements if the applicant
demonstrates that the well construction meets the general performance criteria
in subparagraph (A) of this paragraph. A converted well must meet all other
requirements under this section. The demonstration must include the following:
(I) as-built schematics and construction
procedures to demonstrate that repermitting is appropriate;
(II) recent or newly conducted well-log
information and mechanical integrity test results;
(III) a demonstration that any needed
remedial actions have been performed;
(IV) a demonstration that the well was
engineered and constructed to meet the requirements of subparagraph (A) of this
paragraph and ensure protection of USDWs;
(V) a demonstration that cement placement and
materials are appropriate for CO2 injection for geologic
storage;
(VI) a demonstration that
the well has, and is able to maintain, internal and external mechanical
integrity over the life of the project; and
(VII) the results of any additional testing
of the well to support a demonstration of suitability for geologic
storage.
(C)
Special equipment.
(i) Tubing and packer. All
injection wells must inject fluids through tubing set on a packer. Packers must
be set no higher than 100 feet above the top of the permitted injection
interval or at a location approved by the director.
(ii) Pressure observation valve. The wellhead
of each injection well must be equipped with a pressure observation valve on
the tubing and each annulus of the well.
(2) Construction information. The applicant
must provide the following information for each well to allow the director to
determine whether the proposed well construction and completion design will
meet the general performance criteria in paragraph (1) of this subsection:
(A) depth to the injection zone;
(B) hole size;

strings (e.g., wall thickness, external diameter, nominal weight, length, joint
specification and construction material, tubing tensile, burst, and collapse
strengths);
(D) proposed injection
rate (intermittent or continuous), maximum proposed surface injection pressure,
external pressure, internal pressure, axial loading, and maximum proposed
volume and mass of the CO2 stream to be
injected;
(E) type of packer and
packer setting depth;

description of the capability of the materials to withstand corrosion when
exposed to a combination of the CO2 stream and formation
fluids;
(G) down-hole temperatures
and pressures;
(H) lithology of
injection and confining zones;
(I)
type or grade of cement and additives;
(J) chemical composition and temperature of
the CO2 stream; and
(K) schematic drawings of the surface and
subsurface construction details.
(3) Well construction plan. The applicant
must submit an injection well construction plan that meets the criteria in
paragraph (1) of this subsection.
(4) Well stimulation plan. The applicant must
submit a description of the proposed well stimulation program, including a
description of the stimulation fluids, and a determination that well
stimulation will not compromise containment.
(f) Plan for logging, sampling, and testing
of injection wells before injection. The applicant must submit a plan for
logging, sampling, and testing of each injection well prior to injection well
operation. The plan need not include identical logging, sampling, and testing
procedures for all wells provided there is a reasonable basis for different
procedures. Such plan is not necessary for existing wells being converted to
anthropogenic CO2 injection wells in accordance with
this subchapter, to the extent such activities already have taken place. The
plan must describe the logs, surveys, and tests to be conducted to verify the
depth, thickness, porosity, permeability, and lithology of, and the salinity of
any formation fluids in, the formations that are to be used for monitoring,
storage, and confinement to assure conformance with the injection well
construction requirements set forth in subsection (e) of this section, and to
establish accurate baseline data against which future measurements may be
compared. The plan must meet the following criteria and must include the
following information.
(1) Logs and surveys of
newly drilled and completed injection wells.
(A) During the drilling of any hole that is
constructed by drilling a pilot hole that is enlarged by reaming or another
method, the operator must perform deviation checks at sufficiently frequent
intervals to determine the location of the borehole and to assure that vertical
avenues for fluid movement in the form of diverging holes are not created
during drilling.
(B) Before surface
casing is installed, the operator must run appropriate logs, such as
resistivity, spontaneous potential, and caliper logs.
(C) After each casing string is set and
cemented, the operator must run logs, such as a cement bond log, variable
density log, and a temperature log, to ensure proper cementing.
(D) Before long string casing is installed,
the operator must run logs appropriate to the geology, such as resistivity,
spontaneous potential, porosity, caliper, gamma ray, and fracture finder logs,
to gather data necessary to verify the characterization of the geology and
hydrology.
(2) Testing
and determination of hydrogeologic characteristics of injection and confining
zone.
(A) Prior to operation, the operator
must conduct tests to verify hydrogeologic characteristics of the injection
zone.
(B) The operator must perform
an initial pressure fall-off or other test and submit to the director a written
report of the results of the test, including details of the methods used to
perform the test and to interpret the results, all necessary graphs, and the
testing log, to verify permeability, injectivity, and initial pressure using
water or CO2.
(C) The operator must determine or calculate
the fracture pressures for the injection and confining zone. The Commission
will include in any permit it might issue a limit of 90% of the fracture
pressure to ensure that the injection pressure does not exceed the fracture
pressure of the injection zone.
(3) Sampling.
(A) The operator must record and submit the
formation fluid temperature, pH, and conductivity, the reservoir pressure, and
the static fluid level of the injection zone.
(B) The operator must take whole cores or
sidewall cores representative of the injection zone and confining zone and
formation fluid samples from the injection zone. The director may require the
operator to core other formations in the borehole. The director may accept data
from cores and formation fluid samples from nearby wells or other data if the
operator can demonstrate to the director that such data are representative of
conditions at the proposed injection well. The operator must submit to the
director a detailed report prepared by a log analyst that includes well log
analyses (including well logs), core analyses, and formation fluid sample
information.
(g) Compatibility determination. Based on the
results of the formation testing program required by subsection (f) of this
section, the applicant must submit a determination of the compatibility of the
CO2 stream with:
(1)
the materials to be used to construct the well;
(2) fluids in the injection zone;
and
(3) minerals in both the
injection and the confining zone.
(h) Mechanical integrity testing.
(1) Criteria. This paragraph establishes the
criteria for the mechanical integrity testing plan for anthropogenic
CO2 injection wells that an applicant must include in an
application.
(A) Other than during periods of
well workover in which the sealed tubing-casing annulus is of necessity
disassembled for maintenance or corrective procedures, the operator must
maintain mechanical integrity of the injection well at all times.
(B) Before beginning injection operations and
at least once every five years thereafter, the operator must demonstrate
internal mechanical integrity for each injection well by pressure testing the
tubing-casing annulus.
(C)
Following an initial annulus pressure test, the operator must continuously
monitor injection pressure, rate, temperature, injected volumes and mass, and
pressure on the annulus between tubing and long string casing to confirm that
the injected fluids are confined to the injection zone. If mass is determined
using volume, the operator must provide calculations.
(D) At least once per year until the
injection well is plugged, the operator must confirm the absence of significant
fluid movement into a USDW through channels adjacent to the injection wellbore
(external integrity) using a method approved by the director (e.g., diagnostic
surveys such as oxygen-activation logging or temperature or noise
logs).
(E) The operator must test
injection wells after any workover that disturbs the seal between the tubing,
packer, and casing in a manner that verifies internal mechanical integrity of
the tubing and long string casing.
(F) An operator must either repair and
successfully retest or plug a well that fails a mechanical integrity
test.
(2) Mechanical
integrity testing plan. The applicant must prepare and submit a mechanical

CO2 from each source; and
(D) an analysis of the chemical and physical
characteristics of the CO2 stream prior to
injection.
(2) Maximum
injection pressure. The director will approve a maximum injection pressure
limit that:
(A) considers the risks of tensile
failure and, where appropriate, geomechanical or other studies that assess the
risk of tensile failure and shear failure;
(B) with a reasonable degree of certainty
will avoid initiation or propagation of fractures in the confining zone or
cause otherwise non-transmissive faults transecting the confining zone to
become transmissive; and

installation and use of continuous recording devices to monitor injection
pressure, rate, temperature, and volume and/or mass, and the pressure on the
annulus between the tubing and the long string casing, except during
workovers;
(C) after initiation of
injection, the performance on a quarterly basis of corrosion monitoring of the
well materials for loss of mass, thickness, cracking, pitting, and other signs
of corrosion to ensure that the well components meet the minimum standards for
material strength and performance set forth in subsection (e)(1)(A) of this

every five years unless more frequent testing is required by the director based
on site-specific information; and
(H) additional monitoring as the director may
determine to be necessary to support, upgrade, and improve computational
modeling of the AOR evaluation and to determine compliance with the

and course outlines must be provided to Commission personnel upon request for
the purpose of Commission review to determine compliance with this
paragraph.
(m)
Post-injection storage facility care and closure plan. The applicant must
submit a post-injection storage facility care and closure plan. The plan must
include:
(1) a demonstration containing
substantial evidence that the geologic storage project will no longer pose a
risk of endangerment to USDWs at the end of the post-injection storage facility
care timeframe. The demonstration must be based on significant, site-specific
data and information, including all data and information collected pursuant
subsections (b)-(d) of this section and §
5.206(b)(5) of
this title;
(2) the pressure
differential between pre-injection and predicted post-injection pressures in
the injection zone;
(3) the
predicted position of the CO 2 plume and associated
pressure front at closure as demonstrated in the AOR evaluation required under
subsection (d) of this section;
(4)
a description of the proposed post-injection monitoring location, methods, and
frequency;
(5) a proposed schedule
for submitting post-injection storage facility care monitoring results to the
director;
(6) the estimated cost of
proposed post-injection storage facility care and closure; and
(7) consideration and documentation of:
(A) the results of computational modeling
performed pursuant to delineation of the AOR under subsection (d) of this
section;
(B) the predicted
timeframe for pressure decline within the injection zone, and any other zones,
such that formation fluids may not be forced into any USDWs, and/or the
timeframe for pressure decline to pre-injection pressures;
(C) the predicted rate of
CO2 plume migration within the injection zone, and the
predicted timeframe for the stabilization of the CO2
plume and associated pressure front;
(D) a description of the site-specific
processes that will result in CO2 trapping including
immobilization by capillary trapping, dissolution, and mineralization at the
site;
(E) the predicted rate of
CO2 trapping in the immobile capillary phase, dissolved
phase, and/or mineral phase;
(F)
the results of laboratory analyses, research studies, and/or field or
site-specific studies to verify the information required in subparagraphs (D)
and (E) of this paragraph;
(G) a
characterization of the confining zone(s) including a demonstration that it is
free of transmissive faults, fractures, and micro-fractures and of appropriate
thickness, permeability, and integrity to impede fluid (e.g.,
CO2, formation fluids) movement;
(H) the presence of potential conduits for
fluid movement including planned injection wells and project monitoring wells
associated with the proposed geologic storage project or any other projects in
proximity to the predicted/modeled, final extent of the
CO2 plume and area of elevated pressure;
(I) a description of the well construction
and an assessment of the quality of plugs of all abandoned wells within the
AOR;
(J) the distance between the
injection zone and the nearest USDWs above and/or below the injection zone;
and
(K) any additional
site-specific factors required by the director; and
(8) information submitted to support the
demonstration in paragraph (1) of this subsection, which shall meet the
following criteria:
(A) all analyses and tests
performed to support the demonstration must be accurate, reproducible, and
performed in accordance with the established quality assurance
standards;
(B) estimation
techniques must be appropriate and EPA-certified test protocols must be used
where available;
(C) predictive
models must be appropriate and tailored to the site conditions, composition of
the CO2 stream, and injection and site conditions over
the life of the geologic storage project;
(D) predictive models must be calibrated
using existing information (e.g., at Class I, Class II, or Class V experimental
technology well sites) where sufficient data are available;
(E) reasonably conservative values and
modeling assumptions must be used and disclosed to the director whenever values
are estimated on the basis of known, historical information instead of
site-specific measurements;
(F) an
analysis must be performed to identify and assess aspects of the alternative
post-injection storage facility care timeframe demonstration that contribute
significantly to uncertainty. The operator must conduct sensitivity analyses to
determine the effect that significant uncertainty may contribute to the
modeling demonstration;
(G) an
approved quality assurance and quality control plan must address all aspects of
the demonstration; and
(H) any
additional criteria required by the director.
(n) Fees, financial responsibility, and
financial assurance. The applicant must pay the fees, demonstrate that it has
met the financial responsibility requirements, and provide the Commission with
financial assurance as required under §
5.205 of this title (relating to
Fees, Financial Responsibility, and Financial Assurance).
(1) The applicant must demonstrate financial
responsibility for corrective action, injection well plugging, post-injection
storage facility care and storage facility closure, and emergency and remedial
response until the director has provided to the operator a written verification
that the director has determined that the facility has reached the end of the
post-injection storage facility care period.
(2) In determining whether the applicant is
financially responsible, the director must rely on the following:
(A) the person's most recent audited annual
report filed with the U. S. Securities and Exchange Commission under Section 13
or 15(d), Securities Exchange Act of 1934 (15 U.S.C. Section 78m
or 78o(d)). The date
of the audit may not be more than one year before the date of submission of the
application to the division; and
