DRILLING FLUIDS Drilling Fluid Management & Disposal
Most solids analysis calculations use 2.6 as the assumed S.G. of all drilled solids. In a drilling fluid containing only low-gravity solids and fresh water, the concentration of solids will be a function of fluid density. The same relationship exists if a drilling fluid is composed only of barite and water.

Slop Mud Treatment
Oil-continuous emulsions are often termed slop muds. Oil-based drilling fluids can become contaminated with significant quantities of water as a result of low efficiency well bore displacements to water or brine and from operations such as rig and pit cleaning. The presence of excess emulsifiers and oil-wet solids in typical oil-based drilling fluids allows large …

Understanding Gel Strength of Drilling Mud
The relevant property in this respect is the mud's gel strength. The drilling mud gel strength is caused by the interactive forces between colloids (e.g., clay particles), polymer radicals, or emulsion droplets in mud, which form a more or less rigid structure (gel).
AN EXAMPLE OF MUD RECYCLING SYSTEM Drilling Fluid Management & Disposal
The mud recycling system set up to handle the mud stream and sets out the problems encountered in getting this system running and the alterations planned to enhance the system. The paper also looks at the diffuser losses for 2002 season compared with the combined mud and bagasse losses of previous seasons. The bagasse bed … Continue reading "AN …

COMPARATIVE ANALYSIS OF CARBOXYMETHYL CELLULOSE …
In this study, we sought to formulate a mud with the characteristics of both nondamaging mud and low-solid nondispersed (LSND) mud. Drilling fluids that contain lower levels of solids than conventional clay-based muds at the same density and that can be used for similar purposes are known as LSND muds; these muds sometimes contain less than 5 % ...
EFFECT OF SOLIDS REMOVAL SYSTEM PERFORMANCE
The 4%vol drilled-solids concentration before drilling means that the drilling fluid contained 0.041000 bbl, or 40 bbl of drilled solids when drilling started. After drilling, these 40 bbl plus the 100 bbl of new drilled solids would be in the 1100-bbl drillingfluid system, or (140 bbl / 1100 bbl)100, or 12.7%vol drilled solids.
Retort Water Oil and Solids
Mix the mud sample thoroughly to ensure homogeneity, being careful not to entrain any air, and that no solids remain on the bottom of container. Air or gas entrapment will cause erroneously high retort solids due to reduced mud sample volume. Use a clean syringe to obtain a sample of the mud to be tested.
