Abstract: A technique is provided for estimating perforated entry and exit hole diameters (EHD) of a casing string. In one embodiment, a method for predicting perforation outcomes may comprise selecting one or more variables for a perforating operation, determining an estimate of a perforating outcome for the perforating operation, and correcting the perforating outcome to obtain a corrected perforating outcome by applying a weighting based on historical perforating data.

Abstract: This disclosure may generally relate to perforating operations and, more particularly, may generally relate to systems and methods for estimating perforated entry and exit hole diameters (EHD) of a casing string. In one embodiment, a method for predicting perforation outcomes may comprise selecting one or more variables for a perforating operation, determining an estimate of a perforating outcome for the perforating operation, and correcting the perforating outcome to obtain a corrected perforating outcome by applying a weighting based on historical perforating data.

Abstract: Simulation of downhole transient pressure effects due to propellant stimulation of a formation provides information that may be utilized to select a type of perforating tool system and other components that contribute to effective stimulation of a formation. A well simulator pressure vessel comprises a perforating tool system that comprises a type of perforating gun assembly that includes one or more shaped charges. A propellant disk assembly adjacent to a sample formation is coupled to the perforating tool system. The propellant disk assembly comprises one or more components for securing the propellant. A transient pressure effect may be measured once the one or more shaped charges are detonated and the propellant is ignited or deflagrated. The measured transient pressure effects may be utilized to alter or change the one or more components of the perforating tool system prior to, during, or after stimulation of the sample formation.

Abstract: An explosive charge assembly comprises a housing, a liner disposed on a face of an explosive charge, an opening through the liner disposed at the apex, and a lip disposed around the perimeter of the opening. The liner forms an apex and a mouth opposite the apex, and the liner and the explosive charge are disposed in the housing. The explosive charge is disposed between the liner and the housing, and the lip extends from the liner in a direction towards the mouth.

Abstract: A method and apparatus which provides for a referral program where a financial institution, such as a broker dealer, can refer customers to an independent financial advisor, under an on-going referral fee sharing agreement. The on-going referral fee sharing agreement provides that the financial advisor will pay the referring financial institution an on-going referral fee based on the asset management fee that the advisor charges. These referral fees are processed automatically and the transfers are done electronically, allowing the referral program to be implemented efficiently and effectively.

Abstract: A plurality of objects is deployed in generally radial directions at low velocities in order to achieve a predetermined pattern of the deployed objects. The device has a metal inner wall member (20, 120) having a plurality of annular cylindrical segments of differing outside diameters, an explosive body (22, 122) of low velocity explosive, and a plurality of arrays (40, 140) positioned coaxially with and exteriorly of the explosive body (22, 122) and spaced along the length of the explosive body (22, 122). Each array (40, 140) comprises a plurality of objects (28). The explosive body (22, 122) can be in the form of a plurality of annular sections which provide the objects (28) in each array with an amount of energy different from that provided to each of the objects in the adjacent array. An annular flange (32) can separate the forward end of the explosive body (22, 122) from a booster ring (66), or the booster ring (166) can be positioned within a central cavity of the inner wall member (120).
