As
successful and blessed as Owen Oil Tools was, we were having
difficulties with some international expansions and with our
production enhancement added value strategy. Core Lab offered
Owen the best solution and strategy going forward.
Owen Oil Tools, as a member of the production enhancement
group of Core Lab, is in a unique position to add significant
value to our customers well completions program. We have
joint research projects planned with Stim-Lab, ProTechnics,
and Core Lab’s fluid and rock properties ision.
As a group we plan on not only taking perforating, but more
importantly |
well
completions strategies, into the 21th century. Strategies
that will define success and effectiveness of a well completion
in terms of productivity and not in terms of penetration in
concrete.
After all, we are trying to effectively and efficiently connect the well bore to the reservoir. What company is in a better position to define the best technology to do this than Core Laboratories ? Core Lab a name synonymous with Reservoir Optimization and Owen a name synonymous with Customer Solutions. We look forward to the 21th Century Oilfield!

Greetings to all customers and friends of Owen Oil Tools and Core Laboratories. The last 12 months have been the most dynamic in my eight years at Owen. On July 1, 1998, we became part of Core Lab’s family of companies. This strategy had been discussed for more than two years by Harrold, Dean and myself. We all wanted a way to take Owen to the next level and Core Labs offered us a way to do this.

StimGun™ Assembly & StimTube™ Tool: New Methods for Superior Production Enhancement The StimGun™ Assembly and the StimTube™ Tool represent the state of the art in modern propellant- assisted perforation and stimulation techniques. The Joint Development Team* for the StimGun™ Assembly was a recipient of the 1998 Special Meritorious Award for Engineering Innovation from the Petroleum Engineer International magazine. This proprietary technology continues to gain recognition and acceptance worldwide. Large numbers of successful applications have been carried out using the StimGun™ Assembly and StimTube™ Tool. (*Marathon Oil Company, Owen Oil Tools, HTH, Computalog) The StimGun™ Assembly consists of a sleeve
of proprietary, propellant-like material placed around the
exterior of a perforating gun. The shaped charges ignite
the propellant generating a controlled burst of high-pressure
gas. The gas enters the perforation tunnels and propagates
|
fracture extensions up to 3-6 feet from the end of the tunnel. As the propellant gas rushes back out of the formation it produces a scouring effect removing debris generated during the perforating event. The result is greatly enhanced wellbore communication and production potential. For hard-rock applications impressive production enhancements have been achieved by the use of Owen Oil Tools’ deep penetrating Raptor™ charge in combination with the propellant sleeve. Equally impressive results have been obtained in unconsolidated sands with the combined use of propellant and KISS™ charges manufactured by Owen Oil Tools. In areas requiring hydraulic fracture methods the
use of the StimGun™ Assembly can greatly enhance the
results of the operations. Enhanced wellbore communication
produced by the effects of the propellant result in more
effective and less costly hydraulic fracture operations.
The use of the StimGun™ Assembly results in lower fracture
initiation pressures so that horsepower requirements, and
|
attendant costs, are dramatically reduced. Depending on formation parameters it is sometimes possible to eliminate the need for hydraulic fracture operations. The StimTube™ Tool works on the same principle as the StimGun™ Assembly but is used in the presence of existing perforations. It consists of a cylinder of proprietary, propellant–like material cast onto a specially engineered support tube. A 40gr detonating cord running through the center of the tool serves as the source of ignition. Multiple sections of the StimTube™ Tool may be linked together. A very significant use for this tool is in thru-tubing applications where limited operating diameter precludes the use of the StimGun™ Assembly. Another high-value application is re-stimulation of an interval whose production has declined. The StimGun™ Assembly is sized to fit Owen
perforating guns ranging from 2-3/8” to 7-0”.
Product development continues for additional sizes. The
StimTube™ Tool is available in 1-1/2”,
|
1-11/16”, 2”, 2-1/2” diameters and lengths up to 6 feet. These tools are classed as 5.1 Oxidizers and can be air shipped. They are surface safe, requiring a combination of conditions not normally found on the surface for ignition to occur. The StimGun™ Assembly and the StimTube™ Tool are available through the following licensees: Baker Atlas(U.S. Wireline ), Computalog, Halliburton and JAEX. For more information please contact Brent Kirschner, Sales Representative – Propellant Technology, at Owen Oil Tools or one of the licensees listed above.
