Service Contract No. 14     C-1     -     Galoc  (NW Palawan)
 

(text taken from 2009 Annual Report)

 

In December 2008, block operator Galoc Production Company (GPC) conducted an emergency disconnection of the Floating Production and Storage Offloading (FPSO) from the riser and mooring system (M&RS ) which was damaged as a result of the disconnection and laying down of the M&RS on the seabed, brought about by the adverse weather conditions at the time.  Severe weather condition persisted for about a month.  Repair on the subsea facilities commenced in mid-January 2009.  GPC took advantage of the temporary shutdown of the field to propose, design and install a Hold Back Mooring System (HBMS) on the FPSO as an additional measure to counter the difficulties in maintaining position and to moderate the effects of disconnection to facilities and operations. 

 

The installation of the HBMS and the repair works and modifications to the existing M&RS were completed on the 4th week of February 2009.   The field finally started producing again on February 25, 2009 at an initial stabilized rate of 17,200 barrels of oil per day.  However, inclement weather persisted during most of the middle part of the year which prompted the operator to carry out disconnection of the FPSO and the M&RS on different occasions, resulting in major operational glitches and operational downtime.  Overall, the Galoc Field had a 64% production uptime since it started producing in October 2008 until end of 2009.   During this period, the field produced a total of 3,578,650 barrels.   By the end of 2009, the field was producing at a rate of 10,350 barrels per day.    

 

Also in 2009, the 182-day Extended Production Test (EPT) for the Galoc Field ended.  The EPT was granted by the Department of Energy (DOE) in August 2006 to allow GPC to fully assess the viability of long term production from the field.  The gathered data from the EPT period proved sufficient for this goal, thus the EPT was terminated on June 19, 2009 and commerciality of the field declared on June 22, 2009 with effectivity on June 19, 2009.

 

As of time of writing, GPC have completed thirteen (13) crude oil shipments involving approximately 4,252700 barrels.  Galoc crude buyers included several foreign firms, as well as the state-owned Petron Corporation. 

 

Phase 2 Development

 

As part of the assessment of the Galoc Field for possible Phase 2 development, GPC embarked on re-processing of 3D seismic data covering the Galoc and the adjacent Octon area in Service Contract 6A.  The results are expected to contribute to a better understanding of the Galoc structure and to identify locations for drilling new development wells.  CGGVeritas in London, U.K. was contracted to the re-processing work which ran from March to December 2009.   The resulting pre-stack time migration (PSTM) and pre-stack depth migration (PSDM) data volumes are currently being used in the ongoing evaluation of the Galoc Field.

 

An ongoing series of technical workshops among the Joint Venture partners aims to develop strategies for a second phase development of the Galoc Field.  Focus is centered on confirmation of additional reserves and locating, design, drilling and completion of additional production wells to fully maximize the field’s production potential.  GPC has already identified a number of target well drilling locations with reserves estimate range from 1 MM to 6 MM barrels.  On the production facilities that will be put up, GPC initially had a few choices for the production vessel including retaining the existing FPSO.  At the time of writing, when all options have been thoroughly evaluated, the Consortium is now left with the option of retaining the FPSO but with major modification introduced to its Mooring & Riser System.  Timing for these further development activities is seen towards the 2nd and 3rd quarters of 2010 with a final investment decision expected to be made in September 2010.
