System and method for measuring a flow property of a fluid in a porous medium

A high-temperature drilling fluid is disclosed based on brine and on a mixture of solids of controlled grain size, with water, dissolved salts and insoluble mineral solids comprising at least in part a weighting material of a grain size such that its D50 ranges between 1 and 25 &#x3bc;m and in part colloids of a grain size such that its D50 ranges between 0.2 and 2 &#x3bc;m. The total volume fraction of the solids ranges between 30 and 50% in relation to the total volume, and the total volume comprises at least 10% by volume of the colloids.
