摘要： A method of fracturing multiple zones within a wellbore formed in a subterranean formation is carried out by forming flow-through passages in two or more zones within the wellbore that are spaced apart from each other along the wellbore. The flow-through passages are arranged into clusters, where the directions of all flow-through passages, which belong to the same cluster, are aligned within a single plane (cluster plane). At least one cluster of flow-through passages is formed in each zone. The clusters within each zone have characteristics different from those of other zones provided by orienting the cluster planes at different angles relative to principal in-situ stresses and by placing them into different locations along the wellbore in each of the two or more zones. A propellant pre-fracturing treatment is then performed in the two or more zones to create initial fractures (pre-fractures) in each of the two or more zones. The fracturing fluid in the fracturing treatment is provided at a pressure that is above the pre-fracture propagation pressure of one of the two or more zones to facilitate fracturing of said one of the two or more zones. The pressure of the fracturing fluid is below the pre-fracture propagation pressure of any other non-treated zones of the two or more zones. The isolating of the treated zone is then performed. The fracturing process is then repeated for at least one or more non-treated zones of the two or more zones.

摘要： A sampling assembly of a single packer assembly may have more guard drains than sampling drains. The single packer assembly having the sampling assembly may be deployed in a wellbore formed in a subterranean formation, and the single packer assembly may be deployed on a wireline cable or another deployment or conveyance. The number and the area of the sampling drains, the number and the area of the guard drains, and the positions of the sampling drains and the guard drains may be designed so that the guard drains which are operational may provide a fluid intake rate exceeding a predetermined threshold if one of the guard drains is congested and/or blocked.
