Abstract: A time delay apparatus for use with a downhole tool in a wellbore casing. In an exemplary embodiment, the apparatus includes an electronic circuit comprising a timer, a fusible link, a split spool device that includes a center pin held in place in a restrained position with a spool and a spring element surrounding the spool. A pressure applied to a trigger device, such as a rupture disk, activates a pressure switch and starts a timer, configured with a preset countdown time, in the electronic circuit. On expiration of the timer, the timer block of the electronic circuit generates a signal to cause breaking of the fusible link and releasing of the spring element such that the center pin of the split spool travels to a functional position and activates the downhole tool.

Abstract: A technique is provided for modeling flow simulations at downhole reservoir conditions and rock formations after performing wellbore perforations.

Abstract: A perforating gun system having gun sections coupled together with adapters. Each of the gun sections are adjustable to be offset relative to one another and each gun section is also decentralized with respect to the inside diameter of the wellbore casing. Each of the gun sections are movable in succession to an interval in the wellbore casing to create perforations such that the percentage of the casing openings is large for substantial fluid flow. The alignment and diameters of the gun sections are chosen to occupy the entire inner diameter of the casing.

Abstract: A molded tool is formed from a compression mold material and a corresponding method of manufacture is disclosed. The molded tool has a first end, a second end separated from the first end by a sidewall formed from a heat-sensitive polymeric matrix. The sidewall has an interior surface with a first strength and an exterior surface with a second strength, the first strength being greater than the second strength. Further, the molded tool is formed by a method that includes exerting an expansive force within an interior of the compression mold material, the expansive force having a directional vector along the central axis.

Abstract: A wellbore plug isolation system and method for positioning plugs to isolate fracture zones in a horizontal, vertical, or deviated wellbore is disclosed. The system/method includes a wellbore casing laterally drilled into a hydrocarbon formation, a wellbore setting tool (WST) that sets a large inner diameter (ID) restriction sleeve member (RSM), and a restriction plug element (RPE). The WST is positioned along with the RSM at a desired wellbore location. After the WST sets and seals the RSM, a conforming seating surface (CSS) is formed in the RSM. The CSS is shaped to engage/receive RPE deployed into the wellbore casing. The engaged/seated RPE isolates heel ward and toe ward fluid communication of the RSM to create a fracture zone. The RPE's are removed or left behind prior to initiating well production without the need for a milling procedure. A large ID RSM diminishes flow constriction during oil production.
