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;
Workover means operations on a producing well to restore or increase production.
Exploration Well means a well that is not a development well, a service well or a stratigraphic test well.
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.
Exploratory Well means a well that is not a development well, a service well or a stratigraphic test well.
Exploration means all activities directed toward ascertaining the existence, location, quantity, quality or commercial value of deposits of Products.
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
Exploration Period means the period mentioned in Article 3 during which Exploration Operations may be carried out by the Contractor as provided in Article 3 hereof.
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.
Lot depth means the horizontal distance between the front and rear lot lines.
Injection well means a well into which fluids are injected. (See also “underground injection”.)
Drill means a response to a planned, simulated event.
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.
Producing means producing, directing, manufacturing, issuing, publishing, or advertising;
Drilling operations means the drilling of an oil and gas well and the production and completion operations ensuing from the drilling which require entry upon the surface estate and which were commenced after June 30, 1979, and oil and gas geophysical and seismograph exploration activities commenced after June 30, 1983.
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.
Casing means a pipe or tubing of appropriate material, of varying diameter and weight, lowered into a borehole during or after drilling in order to support the sides of the hole and thus prevent the walls from caving, to prevent loss of drilling mud into porous ground, or to prevent water, gas, or other fluid from entering or leaving the hole.
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.
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.
Commissioning means the process for determining the need for and for obtaining the supply of healthcare and related services by the Trust within available resources.
Grinding means to reduce to powder or small fragments and includes mechanical chipping or drilling.
Hydraulic fracturing means the fracturing of underground rock formations, including shale and non-shale formations, by manmade fluid-driven techniques for the purpose of stimulating oil, natural gas, or other subsurface hydrocarbon production.
Drilling unit means the area fixed for the drilling of one well by order or rule of any state or federal body having authority. If a Drilling Unit is not fixed by any such rule or order, a Drilling Unit shall be the drilling unit as established by the pattern of drilling in the Contract Area unless fixed by express agreement of the Drilling Parties.
borehole means a hole sunk into the earth for the purpose of locating, abstracting or using subterranean water and includes a spring;
Monitoring well means a water well intended for the purpose of determining groundwater quality or quantity.
