Assets & Strategy: Philippines: Nido & Matinloc Oil Fields

Nido Oil Field

The Nido oil field is located in Block A of Service Contract 14 (SC14), at the southern end of the North West Palawan Basin, approximately 60 km west of Palawan Island.

Nido-A was discovered in July 1977 with the drilling of South Nido No.1 - this well was renamed later as Nido-A1. An additional development well, Nido-A2 was drilled in the structure and completed in July 1979.

Nido-B was discovered in January 1978 with the drilling of South Nido West (later renamed Nido-B1). Two additional development wells (Nido-B2 and -B3) were drilled and completed in mid-1979.

Both fields comprise pinnacle or atoll-type carbonate reefs generally of Lower Miocene age. Geological interpretation together with production evidence, show the reservoir to be highly fractured.

Production platform installation at Nido-A and Nido-B was completed in February 1979 with the platforms standing in 43 metres and 78 metres of water, respectively.

Both fields were brought into production in February 1979 with production peaking in mid to late 1979 at over 13,000 bopd and 29,000 bopd for Nido-A and Nido-B, respectively. Both fields were switched to cyclic production regime in mid-1984 with an extended shut-in period between January 1987 and May 1995. By the end of March 2005 total Nido production had passed 17 million barrels of oil.

The Nido fields produce crude oil with a gravity 27°API and 2% sulphur content.

Nido-1X1 oil field is another Lower Miocene pinnacle reef structure similar to Nido-A and -B. It was discovered in August 1979 in 36 metres of water, approximately 2 km to the north-east of the Nido-A field. A 15 metre gross oil column was intersected. The well was tested and a stabilised oil rate of 1,500 bopd was achieved. Subsequent interpretation of 2D seismic data suggests that this well was drilled off structure and that there is upside potential in this prospect.

Nido Petroleum is now undertaking extensive field reviews of the three Nido oil fields to investigate means by which oil reserves can be increased via the implementation of various production enhancement strategies. These strategies include rehabilitation of suspended oil wells, review of attic oil potential, investigation of well workover opportunities, review of artificial lift potential and the possible redrill and development of Nido-1X1.

Following completion of this work, Nido Petroleum intends to make a series of recommendations to the SC14 Joint Venture with a view toward enhancing production from the fields.

Nido's working interest in the Nido oil fields is 22.486%.

Matinloc Oil Field

The Matinloc Oil Field is located in Block B of Service Contract 14 (SC14) approximately 50 km north-west of Palawan Island and 54 km north of the Nido oilfield in the Philippines.

Matinloc is located in 25 metres of water and was discovered in January 1979 with the drilling of the wildcat Matinloc-1 well which intersected a carbonate reef build-up. The field is mapped as a four-way closure with a gross hydrocarbon column of more than 91 metres.

Matinloc-1 was plugged and suspended as a new oil discovery in January 1979. Matinloc-2 and Matinloc-3 were drilled directionally from the Matinloc-1 location in early 1980 and 1982, respectively. Matinloc-4 was also drilled directionally from Matinloc-1 in December 1982 but was plugged and abandoned as it was drilled off structure in to down-thrown section of the field and therefore did not intersect any hydrocarbon bearing formations.

The Matinloc production platform was installed in June 1982 and production commenced in July with a peak production rate of 6,800 bopd being achieved by its three wells - Matinloc-1, -2 and -3. Cyclic production began on Matinloc in January 1997.

Since production start-up Matinloc has produced a total of 11.1 million barrel of oil with an average crude oil gravity of 43° API and a GOR around 218 scf/stb.

Nido Petroleum is now undertaking extensive field review of the Matinloc oil field to investigate means by which oil reserves can be increased via the implementation of various production enhancement strategies. These strategies include rehabilitation of suspended oil wells, review of attic oil potential, investigation of well workover opportunities and a review of artificial lift potential.

Following completion of this work, Nido Petroleum intends to make a series of recommendations to the SC14 Joint Venture with a view toward enhancing production from the field.

Nido's working interest in the Matinloc field is 28.283%.
