Abstract
A downhole tool for perforating a borehole includes a gun body and charges arranged in a helix around the gun body and evenly spaced from both a nearest neighbor along the helix and a nearest neighbor in an adjacent wrap of the helix. Further, placement of the charges is based on a specified diameter of the borehole and specified charge density.
Claims20
A downhole tool for perforating a borehole comprising:
- a gun body;
- and
- charges arranged in a helix around the gun body and evenly spaced from both a nearest neighbor along the helix and a nearest neighbor in an adjacent wrap of the helix, and wherein placement of the charges is based on a specified diameter of the borehole and specified charge density.
A method for manufacturing a downhole tool used to perforate a borehole comprising:
- determining a position for each of multiple apertures formed radially along a helix around a gun body and the apertures are evenly spaced from both a nearest neighbor along the helix and a nearest neighbor in an adjacent wrap of the helix, wherein the position is based on a specified diameter of the borehole and a specified charge density;
- forming a gun body with the multiple apertures at the determined positions;
- and
- placing charges in a central cavity of the gun body and aligning the charges with the multiple apertures.

A method for perforating a formation from within a borehole through the formation, comprising:
- conveying a downhole tool into the borehole, wherein the downhole tool comprises:
- a gun body;
- and
- charges arranged in a helix around the gun body and evenly spaced from both a nearest neighbor along the helix and a nearest neighbor in an adjacent wrap of the helix, and wherein placement of the charges is based on a specified diameter of the borehole and distance specified charge density;
- and
- detonating the charges to form perforation tunnels in the formation.
