n: a well not in use because it was a dry hole originally, or because it has ceased to produce. Statutes and regulations in many states require the plugging of abandoned wells to prevent the seepage of oil, gas, or water from one stratum of underlying rock to another.

n: Usually refers to a well which has no valuable oil or gas production or a dry hole. In general, it should be packed by cement plug.

a relatively impermeable stratum that does not transmit water fast enough to supply a well.

n: a decrease in the volume of a stratum due to pressure exerted by overlying strata, evaporation of water, or other causes.

n: The process of breaking cuttings and compacting it into sample with compaction cell when doing preventing caving test.

a crushing of the matrix structure as overburden loads press down on the rock, reducing the pore space. During production of the well, the load on the matrix increases as the pore-filling fluids are removed. These loads may reduce the porosity of the rock

n: a kind of soft rock stratum with favorable flexibility such as the clay ,rock salt and so on

n: the solid stratum granulosum which forms on the borehole wall after the fluid dehydrations in the layer with cellules




filtration control established on the surface of the wellbore by particles large enough to bridge on the entry of the pores.

n: a type of leakage formation,which is uaually arise in stereoplasm rock stratum.

n: a stratum of rock that contains large void spaces, i.e., a cavernous or vuggy formation.

n: a rock contains large holes.

n: a well through which fluids are injected into an underground stratum to increase reservoir pressure and to displace oil. Also called input well.

n: A well in which fluids are injected rather than produced, the primary objective typically being to maintain reservoir pressure. Two main types of injection are common: gas and water. Separated gas from production wells or possibly imported gas may be rein

a well either specifically drilled, or, more likely, a poor producer that is converted to inject fluids to stabilize the decline of pressure in a productive zone. An injector is required to have a pressure connection to the pay and to a producing well. Wa

n: a bed, or stratum, of rock.

a distinct segment in a vertical stack of formation sequences. Often with areal extent.
