PetroChina made a major gas discovery with its Dabei-3 exploration well in the Kuche Fold and Thrust Belt of the Tarim Basin, northwestern China. The well flowed 10.1 MMcfd and has in-place reserves estimated of 4.6 Tcfg. The well was drilled to a 21,326-ft TD. This is the third major gas field discovery in the region, following the discovery of the Dina-2 and other fields, whose combined reserves are 12-16 Tcfg.
Total made two new gas discoveries in offshore Kalimantan, Indonesia. The East Mandu-1 and West Stupa-1 wells found 538 and 236 ft of pay, respectively, in about 200 ft of water.
Europe. Lundin Petroleum discovered oil with its 16/1-8 well in the Norway sector of the North Sea, 17.5 mi east of Gudrun field. Pay was encountered in a Jurassic sandstone reservoir. The well reached a TD of 7,136 ft in 354 ft of water.
Forest Oil discovered Bomba Field in Central Italy. The Monte Pallano-1 well tested 22 MMcfd equivalent, and the Monte Pallano-2 tested 8 MMcfd equivalent, both without fracture stimulation.
North America. Oilsands Quest discovered tar-sand oil in its Axe Lake discovery in northwest Saskatchewan, Canada. In-place bitumen reserves are estimated to be 1.3-1.5 Bbbl.
Pemex found gas pay in its Lalail well, drilled in 2,600 ft of water in the southeastern offshore region of Veracruz State, Mexico. The discovery is expected to produce about 18 Bcfgd. No details about the pay interval, test rates or potential resource size were mentioned.
Pioneer Natural Resources made two Edwards’ field discoveries in South Texas. The wells each found 150-200 ft of gas pay. Per-well reserves are estimated by the company to be about 4.5-5 Bcfg after fracture stimulation.
Devon Energy discovered gas in its Paktoa C-60 well, drilled off the Mackenzie River Delta in the Canadian sector of the Beaufort Sea. The company estimates recoverable oil reserves of 240 MMbbl, but said that it is unlikely to be developed for more than a decade because of the lack of a pipeline. The Paktoa well was drilled to a 7,900-ft TD in 43 ft of water in Beluga Bay Block EL411.
South America. Petrobras confirmed that its Tupi 1-RJS-628A well discovered a giant field in the Santos Basin, offshore Brazil in Block BM-S-11, with recoverable reserves of 5-8 Bboe. The well was drilled in 2006 to a TD of 19,686 ft beneath a salt structure in 6,975 ft of water.
Solana Resources discovered oil in its Tres Curvas-1 exploration well in the Catatumbo Basin of northeastern Colombia. The well tested 180 bopd from two reservoir zones in the Catatumbo Formation, and was drilled to a TD of 3,550 ft.
