n: (LWD) logging measurements obtained by measurementwhile- drilling techniques as the well is being drilled.

n: The measurement of formation properties during the excavation of the hole, or shortly thereafter, through the use of tools integrated into the bottomhole assembly. LWD, while sometimes risky and expensive, has the advantage of measuring properties of a fo

a technique using a suite of logs that are part of the drilling BHA. The formation properties are measured while drilling (although 40 to 60 feet back from the bit) and the information is pulsed to the surface.

low salt or fresher water.

any of a number of materials that control the loss of fluids to the formation. See Filter Cake.

a high permeability zone that takes fluids from the wellbore and the conventional filter cake building materials have no effect on fluid losses.

n: (loaded on top) a procedure in which tank-cleaning operations are carried out on board ships and the resulting water/oil mixture is collected in a tank and allowed to separate. The relatively clean water is then pumped out of the vessel, and part of the next cargo is loaded on top of the remaining cargo/water-cleaning residue. This residue is called slops.

n: (LIOGA) a group of independent oil producers and persons who own royalties from oil and gas wells in Louisiana. Address: 1 American Pl., Ste. 1020;Baton Rouge, LA 70825;(504) 388- 9525.

n: heavily weighted muds whose high solids content (a result of the large amounts of barite added) necessitates the reduction of clay solids.

n: the filter loss of invert oil mud below 2ml at high pressure and high temperature .
