據(jù)國外媒體5月30日里斯本報(bào)道，葡萄牙能源巨頭Galp能源公司日前在里斯本宣布，該公司與合作伙伴在位于巴西海上桑托斯盆地鹽下地區(qū)的卡爾卡拉發(fā)現(xiàn)所鉆的第二口勘探井鉆遇了輕質(zhì)原油。

發(fā)現(xiàn)井3-SPS-105井非正式稱為卡爾卡拉北井，所鉆的位置在位于BM-S-8區(qū)塊的卡爾卡拉發(fā)現(xiàn)井以北46公里的海上，水深2072米，距離圣保羅州海岸大約229公里。

到目前為止，3-SPS-105井鉆遇了358米高的油柱，高品質(zhì)原油的API度為31，3-SPS-105井在5820米深處的鹽層下面還鉆遇了碳酸鹽巖儲(chǔ)層。壓力數(shù)據(jù)證實(shí)，這是與卡爾卡拉發(fā)現(xiàn)井相同的原油聚集帶。

葡萄牙Galp能源公司通過其麾下子公司Petrogal巴西公司擁有這個(gè)租借區(qū)的14%股份。其他合作伙伴有Barra Energia do Brasil Petroleo e Gas公司和Queiroz Galvvao勘探和生產(chǎn)公司。

Latest Carcará well offshore Brazil proves light oil extension

May 30, 2015

World Oil & Gas News

LISBON, Portugal — Galp Energia says a second well on the Carcará discovery in the presalt Santos basin offshore Brazil has encountered light oil.

Well 3-SPS-105, informally known as Carcará North, was drilled 4.6 km (2.9 mi) north of the discovery well in block BM-S-8 in 2,072 m of water, around 229 km offshore the S?o Paulo state coast.

To date, the well has intersected a 358-m (1,174-ft) column of 31°API oil in good-quality, interconnected carbonate reservoirs below the salt layer at a depth of 5,820 m (19,094 ft). Pressure data have confirmed that it is the same accumulation as of the discovery well.

Galp has a 14% stake in the concession via its subsidiary Petrogal Brasil. The other partners are Barra Energia do Brasil Petróleo e Gás and Queiroz Galv?o Explora??o e Produ??o.
