Section 632-020-0155 - Application to Inject
Universal Citation: OR Admin Rules 632-020-0155
Current through Register Vol. 63, No. 12, December 1, 2024
(1) The provisions of this rule apply to applications for geothermal wells intended for the injection of geothermal fluids, and are in addition to the requirements of ORS 522.019.
(2) An application for a permit to inject geothermal fluid into any underground reservoir must include, but is not limited to, the following:
(a) A plan of
injection explaining the proposed system including facilities other than the
injection well necessary to conduct the operations;
(b) A map of adequate scale (preferably
1:24,000, but not less than 1:62,500 or 1" = 1 mile) to show all existing and
proposed wells, pipelines, and other surface facilities. All wells must be
distinguished by type;
(c) The
injection fluid characteristics such as quality, quantity, source, chemical
analysis, chemical reactivity, toxicity, temperature, and any additives such as
but not limited to pH control, anti-scaling, or biocides;
(d) The characteristics of the proposed
injection zone including: volume capacity of the zone, geologic formation and
structure, porosity, permeability, chemical analysis of zonal water, static
formation pressures and temperatures, anticipated zonal fluid reactivity to the
injected fluids, any previous history of injection operations into the same or
similar formations, any injectivity tests which may have been conducted, and
other pertinent data;
(e)
Description of the hydrology of the surrounding area, including groundwater
quality, quantities, and analyses, and the predicted effects of the injected
fluids on the existing surface and groundwater;
(f) Subsurface maps and cross sections of the
producing and injecting zone structure and lithology and any available logs or
histories of a well or other wells penetrating the injection zone that have not
been previously submitted.
(g)
Description of the effects of injection on such factors as potable water,
seismicity, and local tectonic conditions;
(h) Representative injection well drilling
program;
(i) Proposed downhole and
surface injection equipment and metering facilities with capacity, design
capabilities, and design safety factors in sufficient detail to enable adequate
environmental analysis. Construction and engineering design plans should be
included; and
(j) Proposed
injectivity surveys, seismic surveys, seismic monitoring, and other means to
monitor injection.
