A system that includes an automatic cable head that includes a strain gauge configured to measure a tension associated with a cable attached to the automatic cable head, and a release mechanism configured to connect to a tool, and a controller, configured to receive load data from the strain gauge, and control the release mechanism based on the tension measured by the strain gauge.

A shaped charge for use in a well perforating tool includes at least one explosive component fabricated by an additive manufacturing process such as three-dimensional printing. The additive manufacturing process may facilitate the production of complex geometries including voids and/or density gradients in the explosive materials that, when detonated, produce a specific penetration effect in a wellbore. The explosive materials may be deposited individually as a pellet, or may be deposited on one or both of a case and a liner acting as a scaffold during the additive manufacturing process.

Additive manufacturing of energetic materials in oil well shaped charges

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.

Self correcting prediction of entry and exit hole diameter

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.

Propellant stimulation for measurement of transient pressure effects of the propellant

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.

Jet perforating device for creating a wide diameter perforation

An assembly for an explosive device for severing a well component is provided. The assembly can include an outer housing. The assembly can also include a radially-nonuniform explosive cartridge disposed within the outer housing, and the radially-nonuniform explosive cartridge can include at least four protrusions.
