Filtration Wall Building And Resistivity

The loss of liquid from a mud due to filtration is controlled by the filter cake formed of the solid constituents in the drilling fluid. The test in the laboratory consists of measuring the volume of liquid forced through the mud cake into the formation drilled in a 30 minute period under given pressure and temperature using a standard size cell. It has been found in early work that the volume of fluid lost is roughly proportional to the square root of the time for filtration, i.e.

Drilling Fluid Contamination Test

In preparing a bentonite slurry using fresh water, the bentonite will hydrate and agitation furnished by a mixer is sufficient to separate the hydrated clay plate lets and result in a viscosity and gel strength increase, if the bentonite is placed in salty water or water containing dissolved hardness calcium or magnesium the hydration and subsequent dispersion by agitation is reduced. The question arises, what occurs when salt or hardness is added to a dispersed bentonite drilling fluid and...

A SAND CONTENT DETERMINATION Theory Periodic sand content determination of drilling mud is desirable, because excessive sand may result in the deposition of a thick filter cake on the wall of the hole, or may settle in the hole about the tools when circulation is stopped, thus interfering with successful operation of drilling tools or setting of casting. High sand content also may cause excessive abrasion of pump parts and pipe connections. Sand content is determined by elutriation, settling,...

Oil Well Cementing Properties And Functions

The cement used for oil well cementing differs from concrete or masonry work in that it consists of a thin slurry of primarily cement and water. The cement used in oil wells must possess three primary properties. They must possess a proper water-to-cement ratio, a sufficient fluid time to allow placement, and must develop enough strength in a minimum time to bond the pipe to the formation. Hydration reaction with water begins when water is added to cement. The cement slurry gradually sets to a...

Viscosity, Gel Strength and Yield Point Rheology refers to the deformation and flow behavior of all forms of matter. Certain rheologic measurements made on fluids, such as viscosity, gel strength, etc. help determine how this fluid will flow under a variety of different conditions. This information is important in the design of circulating systems required to accomplish certain desired objectives in drilling operations. Viscosity is defined as the resistance of a fluid to flow and is measured...
