Description
 
The Ca Rong Do prospect is located on Block 07/03 offshore Vietnam in 1,047 feet (319 meters) of water. Premier serves as the operator and holds a 30% interest in the prospect; Pitkin holds a 40% interest; Pearl Oil holds a 15% interest; and Pan Pacific Petroleum holds the remaining 15% interest.

On May 7, 2009, the Hakuryu V semisub drilled an exploration well, 07-CRD-1X, on the block to evaluate the Ca Rong Do prospect. The well lies between the Nam Con Son Basin hydrocarbon fields to the north and the East Natuna Basin discoveries to the south.

The exploration well (07-CRD-1X) reached a total depth of 12,500 feet (3,810 meters), having intersected the targeted intervals. The well encountered oil and gas while drilling.

The operator then drilled CRD-2X, which reached a total depth of 12,418 feet (3,785 meters) below rotary table, and following evaluation of the section by logging, drill stem tests of two reservoir zones in the Oligocene section were conducted.

The first zone tested gas and condensate at rates of 9.7 MMcf/d and 870 bopd, respectively, through a 56/64-inch choke. The total net condensate/gas pay in the well was 236 feet (72 meters), an increase compared with the 56 feet (17 meters) of net pay penetrated in the Oligocene section in the up-dip CRD-1X well.

CRD-2X was sidetracked to further evaluate the distribution of hydrocarbons in the Miocene sands. This sidetrack well reached its planned total depth of 10,958 feet (3,340 meters) BRT in the Miocene section and intersected 60 feet (18.3 meters) of net oil pay in the Miocene sands. This compares with 113 feet (34.4 meters) of net oil pay intersected in the Miocene section in the up-dip CRD-1X well, and 12.5 feet (3.8 meters) in the down-dip CRD-2X well. The well signals the completion of the current phase of drilling in Block 07/03.

Premier plans to conduct a 3D survey to define the resource potential of the Ca Rong Do discovery and adjacent structures and to determine future exploration and appraisal activity.
 
Activities
 
Drillings Wraps Up at Ca Rong Do Discovery
Date: Dec. 2013
Type: Drilling Operations
Pan Pacific Petroleum announced the end of the Ca Rong Do (CRD) exploratory drilling program in Block 07/03 offshore Vietnam. The sidetrack to the CRD-3X well was drilled to 11,906 feet and confirmed 151 feet of net oil pay and 162 feet of net gas pay in the same Miocene reservoir encountered in CRD-3X. Information from both wells will be evaluated to ascertain if CRD possesses enough hydrocarbons and reservoir quality to support a commercial development. Once the wells are plugged and abandoned, the Ocean General (mid-water semisub) will mobilize to the western side of the block to spud the CD-1X well at the Silver Sillago prospect.
Ca Rong Do JV to Seek Out Additional Miocene Reserves
Date: Oct. 2013
Type: Appraisal Operations
Drilling operations at the CRD-3X appraisal well offshore Vietnam have come to an end after the Ocean General (mid-water semisub) successfully intersected the Miocene and Oligocene objectives. Approximately 94 feet of net oil pay and 40 feet of net gas pay were encountered in the Miocene sandstone interval. Evaluation of the Oligocene interval revealed the presence of reservoir quality sands but no signs of hydrocarbons. Preparations are underway to conduct a drill stem test (DST) across the Miocene interval. Once complete, CRD-3X will be sidetracked to the south to determine the potential for additional Miocene reservoirs.
Ca Rong Do Appraisal Underway off Vietnam
Date: Sep. 2013
Type: Drilling Operations
The Ocean General (mid-water semisub) spudded the CRD-3X appraisal well in Block 07/03 off Vietnam at the end of August 2013. The well is designed to appraise the Ca Rong Do oil and gas/condensate discovery and to resolve resource uncertainties associated with the field’s Miocene and Oligocene reservoirs. Target depth of the well is 12,093 feet. Discovery well CRD-1X was drilled in 2009 and flowed oil and gas at a rate of 3,265 bopd and 8.1 MMscf from two Miocene zones. The first appraisal, CRD-2X, followed in 2011 and flowed gas and condensate from two Oligocene zones with varying results. Once drilling is complete, the rig is expected to mobilize within the block to drill the Ca Duc exploration well.
