1 MARINE GEOPHYSICS BP WEST JAVA, ONWJ, PIPELINE INSPECTION BY VESSEL BASED SURVEY BP Offshore North West Java Indonesia Description: PT EGS Indonesia was awarded a contract for a high order acoustic (multibeam & sidescan sonar) survey of BP West Java's entire pipeline asset database in the Offshore NW Java PSC. The survey essentially covered approx 390 pipelines (~1900 pipeline km) and 14 flow centre sites and was carried out using the MV Northern Light equipped with Simrad EM3002 swathe bathymetry and Edgetech FS4200 digital high resolution sidescan sonar. Offshore work was from August to December Reporting and processing work comprises in excess of 390 individual reports and is being carried out in EGS processing and charting center in Hong Kong.

2 GEOTECHNICAL SERVICES DEEPWATER GEOTECHNICAL SAMPLING, PISTON CORING AND GEOCHEMICAL SURVEY Talisman (Sageri) Ltd. Makassar Strait South Sulawesi Indonesia Description: PT EGS Indonesia has recently completed a comprehensive geotechnical, geochemical and bathymetric survey for Talisman (Sageri) Ltd. in the Sageri block, located in 2000m water depth offshore Makassar, South Sulawesi, Indonesia. The work was completed in November The survey work was designed to acquire and process data, by deploying during a single campaign: heat flow measurements using a 6m Lister-type probe; geochemical and geotechnical sampling and analyses with piston-coring acquisition; hydrographic acquisition during seabed survey (multi-beam bathymetry and backscatter imaging). The survey work was carried out using the Indonesian Research Vessel KR Baruna Jaya VIII. For the geochemical sampling and heatflow measurement, PT EGS Indonesia was assisted by TDI Brooks International Inc., who also carried out the geochemical sample analysis in their laboratories in Texas, USA. The final survey program consisted of acquisition of just over 1000km of bathymetric data covering several 10km x 10m blocks of interest, thirty 6m piston cores and 10 heatflow probes, all in water depths of ranging from 1400m to 2100m. Final charting and reporting was carried out EGS own office facilities in Jakarta. PT EGS Indonesia Tel: Fax: [email protected]

3 METOCEAN & MARINE ENVIRONMENT PERTAMINA TRANS JAVA GAS PIPELINE PHASE III MEASUREMENT OF CURRENTS AT EIGHT LOCATIONS Pertamina Pagerungan Island Porong, Surabaya Indonesia Description: EGS was instructed to undertake environmental measurements through Pertamina, as a part of a metocean condition survey between Pagerungan Island and Porong, Surabaya. The objective of the survey was to measure currents close to the seabed at eight positions along the East Java Gas Pipeline. The instruments were installed in August 2006 and recorded current measurements for a period of 65 days, until November Identical sets of instruments were deployed at each location. This consisted of an Aanderaa Instruments model RCM9LW acoustic current meter deployed together with an ORE coastal acoustic release transponder (CART) system. The installation was carried out from the PT Sudjaca Palembang tug utility vessel, Tug Boat Pesut 1. The recovery was carried out from the oceanographic survey vessel, RV Baruna Jaya 7.

4 MARINE GEOPHYSICS PLUTO DEEPWATER AUV GEOPHYSICAL SURVEY Geoconsult North West Shelf Australia Description: EGS (Asia) Ltd (EGS) was appointed to supply Geophysical and Survey support services to Geoconsult of Norway for the PLUTO Deep Water AUV Geophysical Survey of water depths between 200 and 1200m. The Pluto Field is situated approximately 185km North West of Dampier, Western Australia. Survey operations were undertaken on the vessel SV Geosea and utilized a Geoconsult AUV with multibeam, chirp and SSS capabilities. The EGS in-house software package C-View was used for Seabed Data Management and generation of SSS Mosaics. EGS (Asia) Ltd. Tel: Fax: [email protected]

5 POSITIONING AND CONSTRUCTION SUPPORT RAJAHMUNDRY G1 GS15 FIELDS PLIB WORKS BY ROV TRENCH TST Canyon Offshore India Description: EGS have been appointed by Canyon Offshore as a survey subcontractor to provide survey and positioning support for the ROV and PLIB operations. The work included the trenching operation of a main umbilical to a depth of 0.5m along a 18km long route using an ROV Trencher TST208 from DPSV Toisa Mariner Upon the completion of the trenching operation, a post-trenching survey was carried out using the same ROV equipment with a TSS340 cable tracking system to confirm the burial depth.

7 METOCEAN & MARINE ENVIRONMENT SOUND MONITPRING DURING HYDROCARBON EXPLORATION DRILLING OPERATIONS Japex Phillipines Inc Tanon Strait Philippines Description: Japex Philippines Inc, part of the Japan Petroleum Exploration group of companies, licenses a hydrocarbon block in the Tañon Strait between Cebu and Negros, Philippines. As part of the hydrocarbon exploration, a borehole was drilled by the rig Hakuryu V in the Strait off the town of Pinamungajan, south east of Toledo City, Cebu. Concern was expressed that sounds from the drilling rig could affect fisheries or marine mammals in the Tañon Strait. To quantify the acoustic affect of the drilling operations, Japex Philippines Inc commissioned EGS (Asia) Ltd to measure the underwater sound levels in the area while the drilling was in progress, over a 2 weeks period.
