  • Patent number: 5031536
    Abstract: An igniter is set forth in the present disclosure for use with a coring gun assembly. A bullet equipped with a bottom and having an O-ring thereabout is positioned in a chamber at one end thereof for firing to take a core sample. At the opposite end, an igniter is positioned in the chamber resting primarily on a shoulder aligning an elongate cylindrical shell within the chamber and having an external O-ring for sealing purposes. An elongate electrically insulated conductive firing pin extends through said shell so that an external circuit can be connected thereto to create a firing pulse. The current flows through the pin and through a bridgewire disc positioned at the end of the pin which in turn ignites a prepackaged cylindrical explosive charge to fire the bullet.

  • Patent number: 4750570
    Abstract: Sampling bullets of the type which are fired into rock formation surrounding a wellbore. The core sampling bullet includes an internal core barrel which is defined in part by a core receiving sleeve releasably secured within the bullet structure. Following bullet retrieval, the bullet is disassembled thereby permitting rearward removal of the core sleeve with core entrapped therein. Following extraction from the bullet, the core sleeve protects the core during handling and testing. The removed core sleeve is further closed by end cap members to further secure the core against contamination and against further loss of gas in core sample prior to testing. The bullet construction also provides for efficiency of hydraulic venting during firing and provides efficiently for bullet with core removal by means of one or more cables. Core orientation is also achieved.
