... and using wireline NMR measurements is even more challenging due to higher time after bit and increased mud filtrate invasion. Consequently, its use is restricted to quantifying porosity, and even the basic assessment of bound/free fluid require correct T 2 cutoff to be determined from cores. Traditional...

.... It mainly consists of dolomites interbedded with siltstones, anhydrite, and some shales. The area that this paper examines sits on the northern shelf Midland basin where the dolomite intervals lose some of their porosities and additional layers of anhydrite can be found. The San Andres within our field...

... and porosity under the influence of operating loads can help in addressing some of the above presented issues. In what follows, we show the application of NMR measurements in the cement industry, the design of an experimental program for oilfield cements, and results’ interpretation. Nuclear Magnetic...

... method ( Eq. 3 ) for relating UCS and porosity uses UCS data that has been collected from laboratory testing on core, cast, and tuff samples. Statistical analysis of the samples proved that both the cast and core samples are feasible for modeling rock UCS and porosity ( Erfourth et al. 2005 ). (3...
