Title (EN) METHOD OF FRACTURING SUBTERRANEAN FORMATIONS
(FR) PROCÉDÉ DE FRACTURATION DE FORMATIONS SOUTERRAINES
Abstract: front page image
(EN)A method of fracturing subterranean formations which comprises using a low residue fluid that facilitates the clean up of the wellbore following the treatment is disclosed. The system includes a surfactant compound that forms micelles above a critical concentration. Under certain conditions the addition of an associative thickener compound yields a network based on hydrophobic interactions. The resulting viscous fluid can transport proppants, be applied neat or as a foamed or energized system, or used in an acidizing treatment. The method may further include a breaking step.
(FR)L'invention porte sur un procédé de fracturation de formations souterraines qui comporte l'utilisation d'un fluide pauvre en résidus, ce qui facilite la purification du puits de forage après le traitement. Le système comprend un tensioactif qui forme des micelles au-delà d'une concentration critique. Dans certaines conditions, l'ajout d'un épaississant associatif produit un réseau fondé sur des interactions hydrophobes. Le fluide visqueux obtenu peut transporter des agents de soutènement, peut être appliqué pur ou sous forme de système expansé ou énergisé, ou peut être utilisé dans le cadre d'un traitement acidifiant. Le procédé peut également comprendre une étape de fissuration.
