DynaEnergetics offers a suite of leading perforating solutions that optimize performance and boost productivity in conventional oil and gas well completions. Our systems and components are trusted by E&P companies and wireline operators worldwide for efficiently meeting a range of perforating needs in conventional well applications including overbalanced and underbalanced perforating, limited entry and sand control.
underbalanced or overbalance?
Originally used to perforate thinly-laminated pay zones in conventional wells and wells undergoing acid stimulation, limited entry guns can include several short guns run in tandem or long carriers with blank sections. Recently, the shale-drilling business called for high-shot-density perforation clusters to be shot precisely where formation stresses indicate the most likely place from which hydraulic fractures will propagate. As many as 20 short high-shot-density guns and a bridge plug can be deployed in tandem to set the plug and then to selectively perforate each stress concentration for maximum fracture coverage and subsequent reservoir contact. Individually-addressable and intrinsically safe detonators armed and initiated by unique digital codes, the DynaSelect system is highly effective and efficient for limited entry applications. Deep penetrating shaped charges with DPEX energetic liner technology are recommended for many limited entryperforating applications.
For sand control applications oil and gas operators need perforating systems that can deliver big holes at high shot densities. Especially in deep water, sand management experts have agreed the best sand management solution is prevention. Accordingly, wells are perforated with Big Hole charges engineered to create large diameter entry holes to facilitate a subsequent frac-pack or gravel-pack completions. Alternatively, oriented guns loaded with deep penetrating (DP) charges are run and shot into the maximum stress direction of the formation to prevent or delay formation failure and subsequent sand production due to higher drawdown pressures. DynaEnergetics designs manufacture, and qualifies all of the charges, detonating cord, guns, and accessories needed for all types of completions. DynaEnergetics shaped charges have penetrated 19% deeper than the next-best competitor’s product. We offer a complete line of economy, standard and premium charges for the routine to extreme operating conditions. We understand the trade-offs between charge performance and cost and can advise which charge will have the greatest chance to optimize performance.
