Paper Number: SPE-123802-MS
... placed on drilling fluids to be stable at ever increasing temperatures, whilst still maintaining low formation damage potential. OBMs can easily be designed at temperatures where water-based polymers begin to fail. Being based on conventional polymeric viscosifiers and filtration controllers, the HPWBM...

... combination of two new products added to the mud system; a synthetic graphite and an organic polymer which, in combination, provide an effective seal against high permeability formations and substantially reduce occurrences of differential sticking. The synthetic graphite and the polymer, (added in the form...

... particles to enhance fracture tip screenout, along with a synthetic polymer that hydrates in water. When mixed with fresh water and spotted downhole, the polymer can swell up to 400 times its original size. The effectiveness of such treatments help alleviate a lot of the industry troubles by addressing...

... regular acid to create worm hole in the damaged zone. The In-situ gelled acid is tested at the laboratory before performing the job. The polymer was cross linked at pH 2 and the sudden rise in viscosity was to about 1000 m Pa S (cp). The design, quality control and results are detailed in this paper...

... molecular weight polymers have been reduced and exchanged with low molecular weight polymers to enhance hole cleaning throughout the last years. Fewer cuttings are entrapped in beds down hole and are transported up to the surface. The current paper demonstrates how this low viscous/low gel strength drilling...
