Title (EN) FLUID LOSS CONTROL ADDITIVES AND SUBTERRANEAN TREATMENT FLUIDS CONTAINING THE SAME
(FR) ADDITIFS REGULANT LES PERTES DE FLUIDE ET FLUIDE DE TRAITEMENT SOUTERAIN CONTENANT CES ADDITIFS
Abstract: front page image
(EN)Selectively cross-linked starches are disclosed that are useful as fluid loss control additives in subterranean treatment fluids comprising starches that are cross-linked to a Brabender peak viscosity of about 800 to about 1250 Brabender units after about 40 to about 70 minutes at about 92 °C and provide good fluid loss control over a temperature range of from about 20 °C to about 160 °C (68 °F to 320 °F).
(FR)On décrit des amidons sélectivement réticulés qui sont utiles qu'en tant qu'additifs régulant les pertes de fluide dans des fluides de traitement souterain comprenant des amidons qui sont réticulés à une viscosité maximale Brabender comprise entre environ 800 et environ 1250 unités Bradenber après une période d'environ 40 à environ 70 minutes à une température approximative de 92 °C. Ces amidons assurent une bonne régulation des pertes de fluide sur une plage de température comprise entre environ 20 °C et environ 160 °C (68 °F et 320 °F).
