1 Presentation IPS IPS

2 HTH Technical Services, Inc. Joe Haney Owen Oil Tools (CoreLab) Dan Pratt, Chris Montanez, Mike Miller IPS Initial Concept Technical Challenges Progress 2

3  1992 – David Cuthill and Bob Haney  Combine perforating with propellant stimulation  Surface Test - propellant inside gun  Problem with propellant  2007 – HTH and Owen  Start development of a new type of propellant IPS

4 4

5  Quick and Simple Perforation Breakdown PERFORATING CHARGES KODIAK Enhanced Perforating System PELLET 5

6  Initially, the thought was to enhance the perforating process when you can’t run the StimGun Assembly™  Wells with minimal fluid column (< 500 ft)  Wells with complex or difficult casing or tubing configurations  Very short intervals  Limited Entry IPS

7  Ch ange in focus - from charge penetration to flow  Formation breakdown IPS

8 8 Quick and Simple Perforation Breakdown

9  Propellant  Rapid, but controlled, burn rate  Reduced sensitivity of burn rate to pressure  Extremely low sensitively to shock, friction, impact, and static electricity IPS

10  Gun Integrity  For standard and non-standard operating conditions – zero potential for failure needed  Gun expansion – within set limits IPS

11  Adequate Rate of Venting of Gases  We need a high pressure pulse in the perforation tunnel  We have to go through two “chokes”  Both the perforation exit hole in the gun and the in the casing are of critical importance IPS

12  Five different propellant / energetic materials selected for evaluation IPS

13  Testing, Testing, Testing IPS

14  Testing, Testing, Testing IPS

15 IPS

16 IPS

17 IPS

18  All systems “dry” tested  All systems “fluid” rated  Over 100 tests  No problems IPS

19 IPS

20  Multiple new charge and scallop designs evaluated IPS

21 IPS

22  Propellant  Requires high order detonation to fully ignite  Requires minimum charge gram weight to disk thickness to fully ignite IPS

23 IPS  Gun Integrity  No problems – for the “system” 23

24  Venting  The current system with specially designed charges, it is adequate IPS

25 IPS

26 IPS

27 IPS Quick and Simple Perforation Breakdown

28  Wyoming  Montana  Texas IPS

29 IPS

30 IPS Yes Rapid rise time High Pressure 5 ms pulse

31  6’ x 3 3/8” x 4 spf x 60 deg guns  Shallow gas  5½” casing  1700’ depth  50’ to 200’ tamp fluid  Four runs (2 wells)  No operational problems  Gun expansion OK  No wireline damage  No packer problems (all zones – packer was close) IPS

32 IPS

33 IPS

34  TCP – vertical well  11’ x 3 3/8” x 4spf  Corkscrewed 120’ used J-55 tubing, the 60’ of new N-80 above gun was fine  Lesson learned On to Commercial Testing IPS

35  Successes  Shallow gas wells IPS

36  Problems  Inadequate venting rate at depth  Flaw in the Initial Concept IPS

37  Simple operation to breakdown perforations  Not that simple  You need energy (a lot of energy) to breakdown perforations  With a lot of energy, you can have problems with wireline, tubing, plugs and packers  Different formations have different energy requirements IPS

38 IPS

39 IPS Series One 39

40 IPS Series Two 40

41  We have determined that simply reducing propellant load to 85% and setting some fairly basic procedural guidelines - eliminates a majority of the potential operational issues IPS

42 IPS

43  Enhanced Perforating / Perforation Breakdown  Shallow wells (<5000’) IPS

44  Propellant Stimulation / Perforation Breakdown  Moderate depth wells (<10,000’)  Limited Entry  Horizontal wells IPS

45 IPS

46  We are excited about potential of the technology  It work’s (although it is not quick and simple)  There are several commercial applications that we are now focusing on IPS
