Paper Number: SPE-70040-MS
... have a larger effect than shale. In this work, different shaly sand models will be discussed and applied in two field examples to correct the calculated water saturation from shale effect to get the true water saturation level. The contribution of NMR log in solving problems of low resistivity...

... radiate dissipating forces capable of influencing fine-grained sedimentation patterns that often extend for several miles. Consequently, log wavelets in shales may retain signatures relatable to sandstone reservoirs in the area. For many years, faint, almost shaled out sand responses on logs have been...

Paper Number: SPE-59532-MS
... Abstract The alteration of shales, caused by adsorption of water while drilling, is one of many contributors to the wellbore stability problem that costs the industry in the order of $ 400–500 million annually (Bol et.al., 1992). This alteration of shale problem has acquired a logging...

... to identify shale type and hydraulic flow units in shaly sand reservoirs. The four models were derived using available shale models: laminated shale, dispersed shale for low and high shaly formations, total shale, and the Waxman-Smits (W-S) "Cation Exchange Capacity" model. It is found that these four models...

Abstract - Consolidated reservoir formations are defined here as those formations of significant thickness having acoustic impedance (density-velocity product) which is consistently greater than or equal to that of similarly aged, normally pressured shales...

... SPE Members Abstract A new method is presented to determine formation water resistivity (R w) in sandstones. This procedure does not use the Spontaneous Potential (SP) log. Instead formation R w is Potential (SP) log. Instead formation R w is obtained from the overlying shale zones...
