Title
(EN) THE USE OF MICRO-PARTICLE AMORPHOUS SILICATE IN WELL STIMULATION
(FR) UTILISATION DE SILICATE AMORPHE EN MICROPARTICULES POUR LA STIMULATION DES PUITS
Abstract
(EN)
A treatment additive for hydraulic fracturing made of heated silica to create amorphous silicate with a Mohrs hardness between 4.5 and 6 and a particles distribution with maximum diameter between 5 and 2600 microns that has been heated and shaped into amorphous shapes with large surface area to weight ratio and ultra-low settling velocity used to prop microfractures distal from well bore, especially in low viscosity and high temperature wells. The microparticle size and shape allow the treatment to effectively hold microfractures open, stimulate backpressure, and prevent leakoff; which has the added benefit of improving primary fracture development; refrac and frac protect productivity; and reduces the likelihood of interference between offset wells. An additional benefit is that the treatment doesn't contain crystalline silica.
(FR)
L'invention concerne un additif de traitement pour fracturation hydraulique, constitué de silice chauffée afin de créer un silicate amorphe ayant une dureté Mohs entre 4,5 et 6 et une distribution des particules ayant un diamètre maximal entre 5 et 2 600 micromètres, qui a été chauffée et façonnée afin de donner des formes amorphes ayant un rapport élevé aire/poids et une très faible vitesse de décantation, utilisé pour étayer des microfractures éloignées d'un puits de forage, en particulier dans les puits à faible viscosité et haute température. La taille et la forme des microparticules permettent au traitement de maintenir efficacement ouvertes les microfractures, de stimuler la contrepression et de prévenir une fuite ; présentant l'avantage supplémentaire d'amélioration du développement des fractures primaires ; de la productivité de la protection des refracturations et fracturations ; et réduit la probabilité d'interférences entre des puits limites. Un avantage additionnel est que le traitement ne contient pas de silice cristalline.
