Arrow Exploration 于 3 月 22 日在哥伦比亚利亚诺斯盆地 Tapir 区块的 Mateguafa Attic 油田投产了其 Mateguafa 11 评价井。

M-11井于3月9日开钻，3月15日达到实测总深度11,455英尺（垂深9,328英尺），按时完工且低于预算。该井钻遇多个含油气层段，其中包括Carbonera C7组约18英尺的净油层和Carbonera C9组约30英尺的净油层。

Arrow公司在C7区块完成射孔作业后，安装了一台电动潜水泵，使该井投入生产。3月27日，Arrow公司开钻了Mateguafa HZ12水平井，预计4月份投产。M-HZ12井作业结束后，钻机将移至新建成的Icaco井场，进行一口勘探井的钻探，预计将于5月份开钻。

Arrow Exploration brought its Mateguafa 11 appraisal well on production 22 March at its Mateguafa Attic field on the Tapir Block in the Llanos Basin of Colombia.

The M-11 well was spud 9 March and reached a total measured depth of 11,455 ft (9,328 ft true vertical depth) on 15 March, drilled on time and under budget. The well encountered multiple hydrocarbon-bearing intervals, including approximately 18 ft of net oil pay in the Carbonera C7 formation and approximately 30 ft in the Carbonera C9 formation.

Arrow put the well on production in the C7, installing an electric submersible pump after perforating. Arrow spud the Mateguafa HZ12 horizontal well on 27 March, with production expected in April. After M-HZ12, the rig will move to the newly completed Icaco pad for an exploration well expected to spud in May.
