Horizontal perforating: what's next: Promising new techniques are evolving for oriented perforating in extremely long intervals- in horizontal and highly deviated well bores where accurate orientation of the perforations is critical

摘要

Drilling horizontal well sections to maximize production has evolved into a routine practice. On the other hand, tubing-conveyed perforating (TCP) in long, highly deviated or horizontal sections still presents significant completion challenges, most notably: · Maximizing connectivity to the reservoir; · Managing perforating debris in selective completions; and · Controlling sand production by maintaining perforation tunnel stability. Since its introduction in 1997, horizontal oriented perforating has proven its ability to ensure stable formation tunnels and prevent or minimize sand production in moderately competent formations. Combined with deep-penetrating shaped charges, horizontal oriented perforating can maximize reservoir connectivity by penetrating beyond the damaged zone.
