Perforating systems problem is NOT penetration, it’s profitability

Perforating systems problem is NOT's profitability! John Hardesty, Principle Research Engineer at GEODynamics For decades, the perforating industry has focused upon cement penetration as the only measure of performance of perforating products… We didn't look at the shape of the tip… We didn't look at the condition of the sidewall… We didn't look at the amount of clear tunnel that was produced… We didn't look at the hole size and the change in the hole size from the casing to the perforation to the middle of the tunnel to the tip of the tunnel and… We didn't evaluate how that perforation tunnel flowed. Unless, you address all of these factors in perforation design then you're not going to generate the product that delivers the best economical performance for the well. New Standards for Perforation Systems John Hardesty As we move away from evaluating perforation performance in cement, we have to develop tools to predict how these products are going to perform downhole… The Primary Factor John Hardesty The primary factor is the amount of open tunnel. This is affected by the rock that you're perforating, the system in the chart design, and also the conditions that you're perforating in… Narrator The GEODynamics Perforation Flow Lab compares flow performance delivered by computing systems using natural rock targets under representative downhole conditions, systems, techniques & scenarios. John Hardesty We've built a facility that is the best of its kind in the world…to give us information that we have no other way of getting…to make things that haven't been made before. Narrator …application specialists use state-of-the-art software to construct realistic simulations of your downhole opportunity… John Hardesty We start with a cylinder of rock, we apply stress to the outside, pressure to the inside, we simulate the casing and cement of the well, the well bore, and the gun, and all of the surges that happen once we detonate a shape charge and produce a perforation… Narrator GEODynamics’ commitment to testing based on representative conditions enables rapid screening of alternative completion systems, techniques and scenarios. All of these different tests require rock that is like the rock that's downhole. John Hardesty We have a huge library of different targets, everything from a multitude of sandstones...weak to strong, a multitude of carbonates and limestones, shale targets…they are dried to a constant weight, saturated with oil fluid, weighed, measured so that we can calculate the permeability, the porosity and the strength of the target… Development Cell John Hardesty The development cell is very important because it allows us to make a simplified test that gives a first order estimate of geometry at a very rapid rate… Treatment Cell John Hardesty The treatment cell allows us to take an already perforated core and place it at stress and pressure and temperature conditions that might exist in the downhole well, and then treat that perforation tunnel and the surrounding rock with any chemical that we want, so that we understand the chemical interaction with the real geometry of the perforation tunnel instead of just an artificial representation of that tunnel. High Pressure, High Temperature Test Cell John Hardesty Another test capability that we have is a high pressure, high temperature test cell, capable of testing tools up to 9-inches in diameter and up to 15-feet long, up to 40,000 PSI and 500 degrees Fahrenheit. This allows us to take tools all the way to the collapse regime so that we know that when they go into the high-pressure downhole environment they're going to perform.
