n: a chemical used with an acid in well treatment to inhibit the precipitation of insoluble iron hydroxides, which form when the acid contacts scales or iron salts and oxides, such as are found in corrosion products on casing.

n: a circuit that has several electrical devices connected to form a single path for the electric current. The current is the same throughout the circuit;the total voltage is the sum of the voltages across each of the elements of the circuit.

n: 1. a non producing well used for injecting liquid or gas into the reservoir for enhanced recovery. 2. a saltwater disposal well or a water supply well.

n: The well serve to the production well,for example, injection well and measurement well.



a well that is used for purposes other than production.

n: a percentage multiplier of rated horsepower at which a motor may be operated without exceeding the temperature rise limit.

n: the separation of a mineral or royalty interest from other interests in that land given by grant or reservation.

n: nonexpense bearing interest in minerals produced and saved from a tract owned by someone other than the surface owner. Owner of severed royalty interest gets a share of production from wells, but does not have to share the costs of production. The interest may be set up prior or subsequent to the leasing of the land, granted or reserved for years, for life, in fee simple defeasible, or in perpetuity.

spherically focused resistivity log. Measures the resistivity of the flushed zone (Rxo). In a hydrocarbon zone, the curve may report higher resistivity than deep (ILD) or medium (ILM) induction curves because the flushed zone contains mud filtrate and res

n: a fine-grained sedimentary rock: composed mostly of consolidated clay or mud. Shale is the most frequently occur- ring sedimentary rock:.

n: a finely-grained sedimentary rock composed of silt- and clay- sized particles.

a common sedimentary rock with porosity but little matrix permeability. Shales are one of the petroleum source rocks. Shales usually consist of particles finer than sand grade (less than 0.0625 mm) and include both silt and clay grade material.

materials that slow or prevent the mechanical or chemical disaggregation of shale. These materials include inorganic salts and some organic compounds.

n: action or stress that results from applied forces and that causes or tends to cause two adjoining portions of a substance or body to slide relative to each other in a direction parallel to their plane of contact.
