Shallow well means a well located and constructed in such a manner that there is not a continuous layer of low permeability soil or rock (or equivalent retarding mechanism acceptable to the department) at least 5 feet thick, the top of which is located at least 25 feet below the normal ground surface and above the aquifer from which water is to be drawn.
Deep well means a well located and constructed in such a manner that there is a continuous layer of low permeability soil or rock at least 5 feet thick located at least 25 feet below the normal ground surface and above the aquifer from which water is to be drawn.
Oil well means any well capable of producing oil or oil and casinghead gas from a common source of supply as determined by the commission.
Horizontal well means a well bore drilled laterally at an angle of at least eighty (80) degrees to the vertical or with a horizontal projection exceeding one hundred (100) feet measured from the initial point of penetration into the productive formation through the terminus of the lateral in the same common source of supply.
Gas well means a well producing gas or natural gas from a common source of gas supply as determined by the commission.
Water well means an excavation that is drilled, cored, bored, augered, washed, driven, dug, jetted, or otherwise constructed for the purpose of exploring for groundwater, monitoring groundwater, utilizing the geothermal properties of the ground, or extracting water from or injecting water into the aquifer. “Water well” does not include an open ditch or drain tiles or an excavation made for obtaining or prospecting for oil, natural gas, minerals, or products mined or quarried.
Exploration Well means a well that is not a development well, a service well or a stratigraphic test well.
Development Well means a well drilled inside the established limits of an oil or gas reservoir, or in close proximity to the edge of the reservoir, to the depth of a stratigraphic horizon known to be productive.
Dry well means a type of infiltration practice that allows storm water run-off to flow directly into the ground via a bored or otherwise excavated opening in the ground surface.
Test Well means a well constructed for the purpose of obtaining information needed to design a well prior to its construction. Test wells are cased and can be converted to observation or monitoring wells and under certain circumstances to production wells
stratigraphic test well means a drilling effort, geologically directed, to obtain information pertaining to a specific geologic condition. Ordinarily, such wells are drilled without the intention of being completed for hydrocarbon production. They include wells for the purpose of core tests and all types of expendable holes related to hydrocarbon exploration. Stratigraphic test wells are classified as (i) "exploratory type" if not drilled into a proved property; or (ii) "development type", if drilled into a proved property. Development type stratigraphic wells are also referred to as "evaluation wells".
Exploratory Well means a well that is not a development well, a service well or a stratigraphic test well.
Area of shallow flooding means a designated AO or AH Zone on a community's Flood Insurance Rate Map (FIRM) with one percent or greater annual chance of flooding to an average depth of one to three feet where a clearly defined channel does not exist, where the path of flooding is unpredictable and indeterminate; and where velocity flow may be evident. Such flooding is characterized by ponding or sheet flow.
Area A means the area marked “Area A” outlined in red on the Plan (excluding that part shaded grey on the Plan);
Lot depth means the horizontal distance between the front and rear lot lines.
Water Surface Elevation (WSE means the height, in relation to mean sea level, of floods of various magnitudes and frequencies in the floodplains of coastal or riverine areas.
Area B means the populated areas delineated by a red line and shaded in yellow on attached map No. 1, and the built-up area of the hamlets listed in Appendix 6 to Annex I; and
Subsurface tracer study means the release of a substance tagged with radioactive material for the purpose of tracing the movement or position of the tagged substance in the well-bore or adjacent formation.
Injection well means a well into which fluids are injected. (See also “underground injection”.)
Monitoring well means a water well intended for the purpose of determining groundwater quality or quantity.
ILUA Area means the geographical area in relation to which the Framework ILUA applies, as specified in Schedule 2 of the Framework ILUA;
drilling means the act of boring a hole to reach a proposed bottom hole location through which oil or gas may be produced if encountered in paying quantities, and includes redrilling, sidetracking, deepening, or other means necessary to reach the proposed bottom hole location, testing, logging, plugging, and other operations necessary and incidental to the actual boring of the hole;
Zone 3 means all of that part of the Lower Peninsula south of the line described in subdivision (bb).
Urban renewal project means undertakings and activities of a municipality in an urban renewal area for the elimination and for the prevention of the development or spread of slums and blight, and may involve slum clearance and redevelopment in an urban renewal area, or rehabilitation or conservation in an urban renewal area, or any combination or part of them in accordance with an urban renewal plan. These undertakings and activities may include:
Redevelopment Project Area means an area designated by the municipality, which is not less in the aggregate than 1 1/2 acres and in respect to which the municipality has made a finding that there exist conditions which cause the area to be classified as an industrial park conservation area or a blighted area or a conservation area, or a combination of both blighted areas and conservation areas.
Workover means operations on a producing well to restore or increase production.
