The French Institute for Protection and Nuclear Safety(IPSN) is investigating the argillaceous formation of Tournemire(France) as a methodological underground laboratory for conducting research on the feasibility of deep geological repositories for radioactive waste in argillites. Because of the very low water content and hydraulic conductivity of the argillites, the migration through this media should be very low. The fluid flow regime and transport have been studied using natural tracers from the interstitial water.  1, record 10, English, - methodological%20underground%20laboratory

A log is the recording of one physical property of the formation crossed through by a borehole or of the geometric characteristics of the hole or casing or the flow behavior of a well as a function of depth. Wireline logging is performed with a sonde or probe lowered into the borehole or well, usually after the drillstring has been withdrawn.  4, record 13, English, - wireline%20log

Measurements include electrical properties... sonic properties, active and passive nuclear measurements, dimensional measurements of the wellbore, formation fluid sampling, formation pressure measurement, wireline-conveyed sidewall coring tools, and others. In wireline measurements, the logging tool(or sonde) is lowered into the open wellbore on a multiple conductor, contra-helically armored wireline. Once lowered to the bottom of the interval of interest, the measurements are taken on the way out of the wellbore. This is done in an attempt to maintain tension on the cable(which stretches) as constant as possible for depth correlation purposes... Most wireline measurements are recorded continuously even though the sonde is moving.  3, record 13, English, - wireline%20log

Another important type of non-Newtonian fluid is a viscoplastic or "yield stress" fluid. This is a fluid which will not flow when only a small shear stress is applied. The shear stress must exceed a critical value known as the yield stress... for the fluid to flow. For example, when you open a tube of toothpaste, it would be good if the paste does not flow at the slightest amount of shear stress. We need to apply an adequate force before the toothpaste will start flowing. So, viscoplastic fluids behave like solids when the applied shear stress is less than the yield stress. Once it exceeds the yield stress, the viscoplastic fluid will flow just like a fluid. Bingham plastics are a special class of viscoplastic fluids that exhibit a linear behavior of shear stress against shear rate.... Examples of viscoplastic fluids are drilling mud, nuclear fuel slurries, mayonnaise, toothpaste, and blood.  1, record 14, English, - yield%20stress%20fluid
