摘要： A tool assembly for performing a wellbore operation including an actuatable tool, a location device, and on-board controller are together dimensioned and arranged to be deployed in the wellbore as an autonomous unit. The actuatable tool, such as a perforating gun having associated charges, perforates a wellbore along a selected zone of interest. The location device, such as casing collar locator, senses the location of the actuatable tool based on a physical signature provided along the wellbore. The on-board controller or micro-processor is configured to send an activation signal to the actuatable tool when the location device has recognized a selected location of the tool based on the physical signature. The tool assembly further includes a multi-gate safety system. The safety system prevents premature activation of the actuatable tool.

摘要： Systems and methods for creating a hydraulic barrier at an interface between high and low permeability regions that may exist in high permeability-contrast subterranean formations. These systems and methods may include providing injection and/or production wells that are completed within the high and/or low permeability regions, supplying a pore throat blocking agent to an interface between the high and low permeability regions, and forming the hydraulic barrier at the interface. The pore throat blocking agent may be sized to substantially flow through the high permeability region while being substantially blocked, or occluded, from the low permeability region. In some embodiments, the hydraulic barrier may be greater than one acre (0.4 hectare) in area. In some embodiments, the subterranean formation may include an oil reservoir. In some embodiments, the high and/or low permeability formations may be swept concurrently and/or independently to remove oil from the oil reservoir.

摘要： Methods and apparatus for actuating a downhole tool in wellbore includes acquiring a CCL data set or log from the wellbore that correlates recorded magnetic signals with measured depth, and selects a location within the wellbore for actuation of a wellbore device. The CCL log is then downloaded into an autonomous tool. The tool is programmed to sense collars as a function of time, thereby providing a second CCL log. The autonomous tool also matches sensed collars with physical signature from the first CCL log and then self-actuates the wellbore device at the selected location based upon a correlation of the first and second CCL logs.

摘要： Drill bits are provided. The drill bits are of the fixed-cutter, rotary-type. The drill bits have a plurality of blades having cutting elements disposed therealong. Junk slots are formed between the respective blades. A knife opening is formed in at least two of the junk slots. Preferably, the knife openings are disposed substantially transverse to a longitudinal axis of the drill bit. The drill bit also has one or more ribbon cutters. The ribbon cutters cyclically protrude through knife openings in the junk slots in order to facilitate the fragmentation of cuttings ribbons moving through the junk slots during a drilling operation.
