Title (EN) COMMUNICATING HORIZONTAL WELL NETWORK
(FR) RESEAU DE PUITS HORIZONTAUX COMMUNIQUANTS
Abstract:
(EN) A method of producing fluids from a subterranean formation (10) through a single well (1) in a network of separate well-bores, comprising the steps of forming a well (1) having a horizontal section (3) located within the formation (10), completing and equipping such well (1) to produce fluids from the formation (10), producing fluids from the formation through such well (1); forming at least one additional well (2) having a horizontal section (4) located within the formation (10) such that such well (3) is in fluid communication with the first well (1), without intersecting with the horizontal section (3) of the first well (1), and using such additional well (2) as a conduit within the formation to allow and cause fluids contained in the formation which drain or flow into the horizontal section (4) of such additional well-bore, to flow to and be produced through the first well-bore (1).
(FR) L'invention concerne un procédé d'extraction de fluides provenant d'une formation souterraine (10), à travers un puits (1) unique dans un réseau de puits de forage distincts, comprenant les opérations suivantes: formation d'un puits (1) à section horizontale (3) et situé dans la formation (10), finition et équipement de ce puits (1) pour permettre l'extraction de fluides provenant de la formation (10), extraction des fluides de la formation à travers ce puits (1); formation d'au moins un puits (2) additionnel à section horizontale (4) situé dans la formation (10), de manière que ce puits (3) se trouve en communication fluidique (3) avec le premier puits (1) et ne présentant pas d'intersection avec la section horizontale du premier puits (1), sans recouper la section horizontale (3) du premier puits (1), et utilisation de ce puits (2) additionnel comme conduit à l'intérieur de la formation, pour permettre ou provoquer l'écoulement des fluides contenus dans la formation et qui drainent ou s'écoulent dans la section horizontale (4) de ce puits additionnel, en direction du premier puits (1) pour en être extraits.
