n: the surface that separates each successive layer of a stratified rock from the preceding layer. It is here that minor changes in sediments or depositional conditions can be observed.

surface separating layers in a sandstone. Usually bedding planes mark the transition of the particle transport event. An accumulation of minerals or other materials laid down at the time of rock deposition or generated by reworking, that may create signif

n: 1. In geology, any sharp or welldefined boundary between two different bodies of rock. 2. A bedding plane or unconformity that separtaes formations.

the depth of the interface between the oil and water, oil and gas, or water and gas.

n: 1. a European term for the depth of liquid in a storage tank. 2. formation dip. See formation dip. iMage. ullage.

n: the angle at which the bed of formation slopes away from the horizon

the angle that the structural surface or bedding plane or fault surface makes with the horizontal. Measured perpendicular to the strike and in the vertical plane.

a fissile rock tends to break along a plane or planes that are roughly parallel to the bedding planes.

n: wireline logging tool that takes several sets of microresistity readings and produces an image of the borehole wall. Can show fractures,bedding planes,and differentiate.

n: the permeability of reservoir rock parallel to the bedding plane. Compare vertical permeability.

n: a directional well that reaches an inclination of 90 degree

for a strict definition, a 90o deviated well. Actually the well covers a range of “highly” deviated wells (80o to >90o). In the strictest terms, the deviation is measured as 90o from vertical, but tilting bedding planes may make the deviation to the beddi

n: a phenomenon in which a rock formation is broken apart along bedding planes or in which natural cracks are widened by the application of hydraulic pressure. It is sometimes called breaking or cracking the formation, earth lifting, or formation fracturing.

n: see hydraulic fracturing.

v: the partial or complete collapse of the walls of a hole resulting from incompetent, unconsolidated formations, high angle or repose and wetting along internal bedding planes. See also heaving and cave-in.
