在 Mateguafa 11 (M-11) 井取得成果后，Arrow Exploration 正在哥伦比亚准备开展进一步的钻探活动。该井发现了含油砂层，并延伸了 Mateguafa Attic 构造。

M-11井钻探至总测量深度11,455英尺（垂深9,328英尺），在卡博内拉组C7和C9地层中发现了油气，其中C7地层净油层厚度为18英尺，C9地层净油层厚度为30英尺。公司计划对这两个地层进行射孔，首先投产C7地层，预计未来几周内将实现首次产油。

钻井结果表明，这些油藏的构造高于之前钻探的 Mateguafa Attic 油井，向南延伸了油田，并支持进一步的开发钻井。

Arrow公司计划随后钻探一口水平井（M-12Hz），目标井层为C9，预计将于3月底开钻。之后，钻机将移至Icaco井场，钻探Icaco 1勘探井。

Arrow Exploration is preparing further drilling activity in Colombia following results from its Mateguafa 11 (M-11) well, which encountered oil-bearing sands and extended the Mateguafa Attic structure.

The M-11 well was drilled to a total measured depth of 11,455 ft (9,328 ft TVD) and identified hydrocarbons in the C7 and C9 Carbonera formations, with 18 ft of net pay in C7 and 30 ft in C9. The company plans to perforate both zones and initially bring the C7 interval into production, with first output expected in the coming weeks.

The well results indicate the zones are structurally higher than previously drilled Mateguafa Attic wells, extending the field to the south and supporting additional development drilling.

Arrow then plans to drill a horizontal well (M-12Hz) targeting the C9 formation, with spud expected by the end of March. The drilling rig will then move to the Icaco pad to drill the Icaco 1 exploration well.
