KrisEnergy Ltd. (KrisEnergy or the Company), an independent upstream oil and gas company, announced Wednesday that the CGG Amadeus vessel has commenced a 220 square mile (570 square kilometer) 3D seismic acquisition program in the Block 120 exploration acreage offshore central Vietnam.
Block 120 covers 2,652 square miles (6,869 square kilometers) overlying the Quang Ngai Graben and the Tri Ton Horst where water depths range from 164 to 2,132 feet (50 to 650 meters). The graben connects the Song Hong and Qiongdongnan Basins in the north to the Phu Khanh Basin in the south.
The survey, which is expected to take 23 days, is designed to image the carbonate and basement sections of the Ca Lang prospect and associated leads on the Tri Ton Horst. It will tie into a 194 square mile (502 square kilometer) 3D seismic dataset, which was acquired in 2012. The 1993 120-CS-1X exploration well encountered good oil shows whilst the Ca Ngu-1 well drilled in 2013 intersected a 66-foot (20-meter) oil and gas column; both confirm the existence of a petroleum system in the area. The Ca Lang prospect lies approximately 15.5 miles (25 kilometers) to the southeast of the Ca Ngu-1 location.
Chris Gibson-Robinson, KrisEnergy’s director Exploration & Production, commented: “In the last 14 months, we have undertaken detailed analysis of our geological model for Block 120, incorporating the data from the Ca Ngu-1 well. Now our attention is focused on the Ca Lang area and we look forward to being able to more clearly map and further de-risk the prospect, which we believe has a high chance of intersecting hydrocarbons in multiple objectives.”
KrisEnergy holds a 33.33 percent working interest in Block 120 and is partnered by Eni Vietnam B.V. as the operator with 66.67 percent working interest. CGG Amadeus is owned by PTSC CGGV Geophysical Survey.
