Bernoullis theorem n: a mathematical expression of the conservation of energy in streamline flow;the theorem states that the sum of the ratio of the pressure to the mass density, the product of the gravitational constant and the vertical height. and the square of the velocity divided by 2 are constant.

n: a solid steel cylinder used to produce seamless casing. The billet is pierced lengthwise to form a hollow tube that is shaped and sized to produce the casing.

below mud line. BMP: best management practice.

n: when casing is being cemented in a borehole, the cement slurry can fail to rise uniformly between the casing and the borehole wall, leaving spaces devoid of cement. Ideally, the cement should completely and uniformly surround the casing and form a strong bond to the borehole wall.
