雷普索尔在圭亚那发现石油

中国石化新闻网讯 据1月3日Offshore Energy报道，西班牙石油和天然气公司雷普索尔在圭亚那近海Kanuku区块的carpa -1探井发现了石油。

雷普索尔是Kanuku区块的运营商，持有37.5%的股份。图洛石油持有37.5%的股份，道达尔持有剩余25%的股份。

图洛石油此前表示，根据初步数据，carpa -1探井已遭遇了约4米的净油层，白垩纪的高产油层已延伸至该集团在圭亚那开采区。

根据图洛公司提供资料，钻探、电缆测井、压力测试和储层流体取样的初步结果表明，在上白垩世砂岩储层中发现了石油。现场勘测表明，原油API度为27，含硫量小于1%。

图洛表示，将在适当时候对石油质量进行详细的实验室分析。卡拉帕油田的发现表明白垩纪的石油开采活动从斯塔布鲁克区块向南延伸到了Kanuku地区。尽管净产量低于钻探前的预测，但API度为27的原油支持了Kanuku和邻近Orinduik油田白垩纪油藏的巨大潜力。

Valaris EXL II自升式钻井平台在68米的水深中钻了3290米深的carpa -1井，现在该井将被堵塞和废弃。

该公司首席运营官马克?麦克法兰(Mark MacFarlane)评论道:“carpa -1井的发现是一个重要的勘探成果，对Kanuku和Orinduik区块都具有积极意义。虽然该地区的净产油量和油藏开发低于我们钻探前的估计，但我们仍受到了鼓舞，并将继续寻找高质量的石油，这也证明了多产的白垩纪油层延伸到了我们的勘探区块上。在决定未来的开发计划之前，我们将把在这些相邻许可证上钻探的三个探井的结果整合到圭亚那和苏里南的地质和地球物理模型中。”

Repsol hits oil pay in Guyana well

Spanish oil and gas company Repsol has encountered oil at the Carapa-1 exploration well drilled on the Kanuku license offshore Guyana.

Repsol is the operator of the Kanuku block with a 37.5% stake. Tullow also holds a 37.5% stake with Total holding the remaining 25%.

Tullow Oil said on Thursday that the Carapa-1 exploration well had encountered approximately four meters of net oil pay based on preliminary interpretation, and has extended the prolific Cretaceous oil play into the group’s Guyana acreage.

According to Tullow, preliminary results of drilling, wireline logging, pressure testing, and sampling of reservoir fluid indicate the discovery of oil in Upper Cretaceous age sandstone reservoirs. Rig site testing has indicated that the oil is 27 degrees API with a sulfur content of less than 1%.

Tullow said that the detailed laboratory analysis of the oil quality would follow in due course. The Carapa oil discovery suggests the extension of the Cretaceous oil play from the Stabroek license southwards into the Kanuku license. While net pay is lower than pre-drill forecasts, the 27 degree API oil supports the significant potential of the Cretaceous play on both the Kanuku and adjacent Orinduik licenses.

The Valaris EXL II jack-up rig drilled the Carapa-1 well to a total depth of 3,290 meters in 68 meters of water and the well will now be plugged and abandoned.

Mark MacFarlane, Chief Operating Officer, commented: “The Carapa-1 result is an important exploration outcome with positive implications for both the Kanuku and Orinduik blocks. While net pay and reservoir development at this location are below our pre-drill estimates, we are encouraged to find good quality oil which proves the extension of the prolific Cretaceous play into our acreage. We will now integrate the results of the three exploration wells drilled in these adjacent licenses into our Guyana and Suriname geological and geophysical models before deciding the future work program.”
