Detection of cement integrity behind resistive casing

Categories: Current Research



The objective of this research is to determine the integrity of cement filling annulus behind fiberglass casing.  The weakly magnetized cements are detected using induction logging​​. The focus  is on numerical simulation of cement containing iron powder magnetization and measurement of magnetic response. We have devised a novel technique for assessing integrity of the weakly magnetic cements behind non-conductive (fiberglass) casing that might be used in the medium-temperature geothermal wells in Saudi Arabia and elsewhere in the Middle East.
