地质公园在哥伦比亚 Llanos 34 Block 发现

2017 年 2 月 6 日

智利圣地亚哥——GeoPark Limited 是一家在哥伦比亚、智利、巴西、阿根廷和秘鲁拥有运营和增长平台的运营商和整合商,宣布在 Llanos 34 区块(GeoPark 拥有 45% 的工作权益进行运营)取得了新的钻探成功。哥伦比亚,包括:1) 在 Chiricoca 1 探井成功钻探和测试后发现新 Chiricoca 油田,以及 2) 在 Tigana Sur 6 成功钻探和测试后进一步扩建 Tigana 油田发展良好。

基里科卡 1 口井

GeoPark 钻探并完成了 Chiricoca 1 号勘探井,总深度为 11,966 英尺。在 Mirador 地层中使用电动潜油泵进行的生产测试导致产量约为 1,000 桶/日,API 度为 34 度,含水率为 9%,通过 33/64 毫米的节流阀和每平方英寸 34 磅的井口压力。还对更深的瓜达卢佩地层进行了测试,并产出了含有微量重油的水。需要额外的生产历史来确定井的稳定流量。地面设施已到位,该井已投入生产。

南蒂加纳 6 井

GeoPark 钻探并完成了 Tigana Sur 6 开发井,总深度为 11,645 英尺。在 Guadalupe 地层下部使用电动潜油泵进行的生产测试导致 15 度 API 的产量约为 1,600 桶/天,产量为 8%含水率,通过 52/64 毫米的节流阀和每平方英寸 70 磅的井口压力。需要额外的生产历史来确定井的稳定流量。地面设施已到位,该井已投入生产。

Tigana Sur 6 井在瓜达卢佩地层下部发现了一个优质储层,净产油层也约为 57 英尺,这表明瓜达卢佩地层下部的平均净产层显着增厚(几乎增加了 60%)。蒂加纳油田的其他生产井。此外,该井在瓜达卢佩地层上部发现了一套新的储砂层,从初步的岩石物理测井信息来看,这些砂层似乎含油。需要进一步的生产测试来确认该区域是否具有产油能力。

GeoPark makes discovery in Llanos 34 Block, Colombia

February 06, 2017

SANTIAGO, Chile -- GeoPark Limited, operator and consolidator with operations and growth platforms in Colombia, Chile, Brazil, Argentina, and Peru, has announced new drilling successes in the Llanos 34 Block (GeoPark operated with a 45% working interest), in Colombia, consisting of: 1) Discovery of the new Chiricoca oil field, following the successful drilling and testing of the Chiricoca 1 exploration well, and 2) Further expansion of the Tigana oil field, following the successful drilling and testing of the Tigana Sur 6 development well.

Chiricoca 1 well

GeoPark drilled and completed the Chiricoca 1 exploration well to a total depth of 11,966 ft. A production test conducted with an electric submersible pump in the Mirador formation resulted in a production rate of approximately 1,000 bopd of 34 degrees API, with 9% water cut, through a choke of 33/64 mm and wellhead pressure of 34 lb per square in. The deeper Guadalupe formation was also tested and produced water with traces of heavy oil. Additional production history is required to determine stabilized flowrates of the well. Surface facilities are in place and the well is already in production.

Tigana Sur 6 well

GeoPark drilled and completed the Tigana Sur 6 development well to a total depth of 11,645 ft. A production test conducted with an electric submersible pump in the lower Guadalupe formation resulted in a pro duction rate of approximately 1,600 bopd of 15 degrees API, with 8 % water cut, through a choke of 52/64 mm and wellhead pressure of 70 lb per square in. Additional production history is required to determine stabilized flowrates of the well. Surface facilities are in place and the well is already in production.

The Tigana Sur 6 well encountered a good quality reservoir in the lower Guadalupe formation, with a net pay of approximately 57 ft, as well, which represents a significant thickening (almost 60% more) of the average net pay of the lower Guadalupe formation in other producing wells in the Tigana oil field. In addition, the well encountered a new set of reservoir sands in the upper Guadalupe formation, which appear to be oil bearing from preliminary petrophysical logging information. Further production testing will be required to confirm if this zone is oil productive.
