an irregular intrusion of an igneous rock into another rock.

n: 1. an obstruction in the borehole, usually caused by the caving in of the well or the borehole or by the intrusion of a large boulder.2.a tool placed in the hole to retain cement or other material;it may later be removed, drilled out, or left permanently.

n: An obstruction in the borehole, caused by a buildup of material such as scale, wellbore fill, or cuttings that can restrict wellbore access or, in severe cases, eventually close the wellbore . In open hole a bridge usually caused by the caving in of the w

a blockage in the wellbore caused by a mass of particles that lock together and prevent pipe movement or flow.

a large igneous intrusion that cuts through the sedimentary layers, creating permeability barriers.

n: Pumping drilling fluid continuously or intermittently into the wellbore to maintain the fluid level in the hole near the surface. The purpose is to avoid danger of blowout, water intrusion and/or caving of the wellbore.

n: an intrusion of formation fluids into the borehole, i.e., a kick.

inflow.

an igneous rock body, which when molten, forced its way into a surrounding rock. Salt intrusions are also possible.

n: the hot fluid matter within the earths crust that is capable of intrusion or extrusion and that produces igneous rock when cooled.

molten rock (lava) that crystallizes into an igneous rock.
