Redistribution of fluids present in well bore environments is disclosed. In some embodiments, the invention may be the redistribution of water produced in a coal bed methane well. The redistribution of water from one aquifer (27) to another aquifer in accordance with the present invention is also disclosed. Furthermore, the injection of a reservoir formation (39) with water, and in some embodiments as a flood of the reservoir formation, in accordance with the present invention is also disclosed. Each of the embodiments of the present invention is disclosed as methods and processes as well as one or more device or apparatus. Such processes and tools may avoid the requirement for surface discharge of water produced in a well bore and may minimize the regulatory costs associated with such water handling. Methods of compliance, water disposal, aquifer recharge, transfer of water from one aquifer to another, and obtaining a permit are also disclosed.
L'invention concerne la redistribution des liquides présents dans les environnements de forage. Dans certains modes de réalisation, l'invention peut porter sur la redistribution de l'eau produite dans un puits de méthane de lit de charbon. L'invention se rapporte aussi à la redistribution de l'eau en provenance d'une nappe aquifère (27) vers une autre nappe. En outre, l'invention concerne l'injection d'eau dans une formation réservoir (39) et, dans certains modes de réalisation, l'extraction secondaire par balayage hydraulique de la formation réservoir. Pour chacun des modes de réalisation, l'invention porte sur des procédés et des processus et sur un ou plusieurs dispositifs ou appareils. Les procédés et outils précités peuvent permettre d'éviter l'évacuation en surface de l'eau produite dans un puits de forage, et de minimiser les coûts associés à la réglementation de la gestion de l'eau.L'invention concerne enfin des procédés de mise en conformité, d'élimination de l'eau, de recharge des nappes aquifères, de transfert d'eau d'une nappe aquifère à l'autre et d'obtention de permis.
