Claims11
A method of perforating a well comprising:
- loading a first perforating gun with perforating charges and an explosive detonating cord, wherein the explosive detonating cord is located proximate to the perforating charges to detonate said perforating charges;
- inserting a cartridge holding a detonator into a detonation transfer end fitting having a cylindrical outer housing with an upper end and a lower end and a cylindrical axis, a first bore of a first diameter along the cylindrical axis with a first end being the upper end and a second end, a second bore of a second diameter along the cylindrical axis starting at the second end of the first bore and having a third end, wherein the first diameter is smaller than the second diameter, and a third bore intersecting both the first and second bore and the exterior of the detonation transfer end fitting;
- inserting the detonation transfer end fitting into the perforating gun;
- inserting the explosive detonating cord into the detonation transfer end fitting;
- confirming the detonating cord is correctly inserted into the detonation transfer end fitting visually through the third bore;
- assembling the perforating gun in a tool string;
- conveying the tool string into the well;
- and
- detonating the perforating charges.
