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.
Abandoned well means a well whose use has been permanently discontinued or which is in a state of disrepair such that it cannot be used for its intended purpose or for observation purposes.
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.
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.
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".
Injection well means a well into which fluids are injected. (See also “underground injection”.)
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
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.
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.
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.
Gas well means a well producing gas or natural gas from a common source of gas supply as determined by the commission.
Exploration Well means a well that is not a development well, a service well or a stratigraphic test well.
Exploratory 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.
Depth , in respect of a building, means the measured distance between the front line of the building and the back line of the rear main wall which separates the main building from the open space;
service well means a well drilled or completed for the purpose of supporting production in an existing field. Wells in this class are drilled for the following specific purposes: gas injection (natural gas, propane, butane or flue gas), water injection, steam injection, air injection, salt water disposal, water supply for injection, observation or injection for combustion.
Well-logging means all operations involving the lowering and raising of measuring devices or tools that may contain sources of radiation into well-bores or cavities for the purpose of obtaining information about the well or adjacent formations.
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.
Built-Up Area and/or “Covered Area” in relation to a Flat shall mean the floor area of that Flat including the area of balconies and terraces, if any attached thereto, and also the thickness of the walls (external or internal) and the columns and pillars therein Provided That if any wall, column or pillar be common between two Flats, then one-half of the area under such wall column or pillar shall be included in the built-up area of each such Flat.
Vapor tight means equipment that allows no loss of vapors. Compliance with vapor-tight requirements can be determined by checking to ensure that the concentration at a potential leak source is not equal to or greater than 100 percent of the lower explosive limit (LEL) when measured with a combustible gas detector, calibrated with propane, at a distance of 1 inch (2.54 cm) from the source.
Infiltrative surface means designated interface where effluent moves from distribution media or a distribution product into treatment media or original soil. In standard trench or bed systems this will be the interface of the distribution media or product and in-situ soil. Two separate infiltrative surfaces will exist in a mound system and an unlined sand filter, one at the interface of the distribution media and fill sand, the other at the interface of the fill sand and in-situ soil.
Cubic Foot means a volume of Gas occupying a space of one cubic foot at a temperature of 60°F and at the applicable Base Pressure.
Subject Lands means the lands subject to or covered by the oil and gas leases described in Exhibit A, insofar and only insofar as they are located within the AMI Area and cover the Target Formation, subject to the exceptions, exclusions and reservations set forth on such Exhibit A.
Monitoring well means a water well intended for the purpose of determining groundwater quality or quantity.
Drill means a response to a planned, simulated event.
Lot depth means the horizontal distance between the front and rear lot lines.
