Paper presented at the SPE EOR Conference at Oil and Gas West Asia, April 16–18, 2012
Paper Number: SPE-151777-MS
... It is clear that clay swelling phenomenon has been investigated by many researchers. Mainly, all theoretical and experimental studies have focused on the occurrence of the swelling of different smectite types such as montmorillonite during EOR-waterflooding operations. Consequently there have...

Paper presented at the SPE Improved Oil Recovery Symposium, April 14–18, 2012
Paper Number: SPE-151776-MS
... Abstract Clay swelling has been recognized as one of the main mechanisms of formation damage during various well operations. Many researchers have extensively investigated the effects of many parameters such as pH, and salinity of water-based fluids on montmorillonite swelling behavior. However...

Paper Number: SPE-62531-MS
... NMR offers a new technique to differentiate between the surficially adsorbed water in montmorillonite from the interstitial pore water in rocks. NMR characterization suggests that the threshold level of adsorbed water in this clay is 500 mg/g of dry clay and this value is an intrinsic property...

..., montmorillonite clay 5% dispersed in a sandpack is more stable in the presence of KC1 than NaCl brines, giving CSC values of 5, 000 and 27, 500 ppm, respectively. Polyacrylamides are much better clay stabilizers than carboxymethyl cellulose (CMC) or xanthan gum (XG), lowering the CSC of KC1 to 1, 000 to 2, 000...

...M. Iltis; G. Didier; P. Laréal This study compares the effectiveness of potassium chloride with guanidine chlorhydrate in the prevention of clay swelling. The results given on various swelling tests on calcic montmorillonite led to the conclusions that (1) guanidine chlorhydrate is more effective...

... engineers and geologists is the observed diagenetic conversion of montmorillonite to mixed-layered clay m~neral forms under conditions of deep sediment burial at low geothermal temperatures (~500°F). The origin of these clay mineral transformations may be related to the existence of the overpressured zones...
