Patent

CA 2552657

New fluids are disclosed for use in servicing subterranean formations containing oil and gas. In particular, an improved chemical gelling additive for hydrocarbon based fracturing fluids is disclosed having reduce, negligible or no volatile phosphorus at temperatures below about 250°C. The viscosity verses temperature behavior of an example fluid is illustrated.

Divulgation de nouveaux fluides destinés à l'entretien de formations souterraines contenant du pétrole et du gaz. En particulier, on décrit un additif gélifiant chimique amélioré pour des fluides de fracturation à base d'hydrocarbure ayant une teneur réduite, négligeable ou nulle en phosphore volatil à des températures inférieures à environ 250°C. On illustre un exemple de fluide en ce qui concerne le comportement de la viscosité par rapport à la température.
