Nido and its Joint Venture partner Kairiki have provided this progress report on the Tindalo-1 well in Service Contract 54 (SC54), located in the NW Palawan Basin, offshore the Philippines.

As of the date of the last report, Tindalo-1 had drilled to a total depth of 1,875 mRT (meters below the rotary table), intersected an oil accumulation and was logging the oil-bearing section with electric wireline logs to confirm the height of the oil column.

Formation Evaluation Highlights

  • Confirmation of a 119 meter oil column with electric wireline logs;
  • 134 meter oil column supported by good oil shows in the absence of wireline logs;
  • Insufficient data to determine any deeper extent of the oil column due to wellbore conditions precluding both wireline logs and mud returns to surface while drilling.

Two Discoveries

Nido's Deputy Managing Director, Joanne Williams, said, "The Tindalo-1 discovery in addition to the previous Yakal-1 discovery greatly increases our confidence in the rapid commercialisation strategy in the SC54 inboard area. The work program in the coming months will include a review of all the data gathered during the drilling program to evaluate the reservoir quality and oil-in-place resource estimates of the Tindalo cluster. The real bonus for us is that as well as Yakal-1 and Tindalo-1 there are in excess of 20 additional prospects in the SC54 inboard area covered by 3D seismic data. With the two out of two result from this drilling program, these future targets only add to the attractiveness of this area."

Nido's Chief Executive Officer, Jocot de Dios also remarked, "We are extremely pleased with, and excited about this second discovery in Tindalo-1 which comes right on the heels of our earlier Yakal-1 discovery. Our success today is a testament to the dedication of the Nido and Kairiki drilling and subsurface teams that worked on this program, the Philippine Department of Energy and the WilBoss rig and her crew.

"Following a drought of 14 years in the sector, these twin discoveries speak eloquently about the Palawan Basin as the premium destination in the Philippines to explore for oil and gas. With Nido holding the dominant position in this world-class Basin, we consider ourselves perfectly poised to execute our greater plans for this area. We remain firmly committed to our exploration program in the Basin and to the country's energy independence initiatives."

Progress Report

Since the last report, a comprehensive wireline logging program has been completed over the top 119 meters of the Nido Formation reservoir. While it was not possible to acquire wireline logs to the well's total depth due to the lost circulation zone intersected while drilling, it is clear from the wireline logs that the oil column extends at least 119 meters, as evidenced by the deepest available wireline data.

Good oil shows while drilling support at least an additional 15 meters of oil column below the logged zone, which could indicate a total column of at least 134 meters. Since there is no data (either from wireline logging or mud returns while drilling) below this point it cannot be determined if, or for how far, the oil column extends below this point.

The current operation underway at Tindalo-1 is to cap and secure the well for completion as a production well for extended well testing at a later date and following this operation the WilBoss jackup drilling rig will be demobilized and be released from contract to SC54.
