1 Products and Services HR3D, AUV3D, Contract Services

2 Mission A technology driven product and service provider with a focus on the marine environment 1. Technology is identified with little or no exploitation in the marketplace 2. Products are developed dbased on the technology and its fit to market need 3. Services are provided utilizing the technology product and the existing iti associated products or services

3 Product Concept HR3D and AUV3D Methods The methods utilizes 2 phases to assess and monitor the overburden. Pre development geohazard survey. Production overburden monitoring. Both products pair to provide a composite 3D image at needed resolutions.

4 HR3D Background Targeting the Overburden Developments in reservoirs often change the shape and nature of the overburden. Detecting these changes allows better understanding of the reservoir behavior. Initial geohazardsurveys can be invalidated by changes in the overburden as the reservoir produces. Detectingthechanges the changes allows better utilization of production equipment and more accurate drilling targets.

5 HR3D Background Safety Above the Reservoir History has shown that production changes the reservoir overburden and the associated installations (Ekofisk, Valhall). Initial high resolution surveys allow the identification of potential risk areas on the seafloor. Monitoring changes in the overburden allows a more proactive approach to the safe design and positioning of production equipment as the reservoir matures.

6 HR3D Background Offshore USA Minimum Impact Installations Recent US legislation has been enacted requiring detailed definition oftheseafloor and near subsurface (CFR ) for archeological significance. Similar legislation in thenorthsea andbrazil require identical investigations.

7 Example North Sea Survey conducted in May 2011 using HTI Seamux HR3D System. Comparisons with traditional 2D. Central North Sea Producing Field: Existing Oil Field Norwegian North Sea Water depth 225 meters Reservoir depth ~2s

20 HR3D Availability EAME 20 x 150m HTI Seamux, 6.25m groups Currently rigged in Bergen NASA 20 x 150, 300, 450m Thales, 12.5m groups Currently staged in Houston Each system is portable Either can be rigged on Each system is portable. Either can be rigged on vessels of opportunity or on our service vessels.

21 AUV3D AUV surveys augment HR3D data and vice versa Provide higher resolution in areas requiring finer detail. Provide attributes needed for evaluating HR3D unknowns. Enhancement AUV Instrument package can provide bridge between traditional Side Scan Sonar or similar surveys and HR3D. HR3D can be tuned in shallow target environments to allow the use of COTS AUV, and AUV Instrumentation.

22 AUV3D Technology Proprietary Deep Water Technology has been proposed as alternative to traditional sub bottom surveys Surveyscan bepared withhigh Res survey to provide a turnkey product for Archeological or Site Survey purposes

23 AUV3D Acquisition Technology AUV s Variable payload AUV s allow standard instrumentation as well as deployment of SO proprietary instrument package. Endurance of 36 hours allows one deployment/survey yfor paired AUV3D/HR3D survey

24 AUV3D Availability Shallow Target (<100ms?) Availability at market demand Deep Water AUV Backlog: ~ 6 months Instrument tpackage: ~ 9 month calibration

25 Other Enhancements Passive Acoustic Monitoring SeaBAM PAM system integrated with HR3D recording system. RGPS Storm RGPS integrated with Ion Spectra allows raw GPS data input for further post processing. Thus the HR3D spread can be post processed via a variety of methods.
