Karoon 表示，LLOG 作为运营商已确认 Who Dat East 和 Who Dat South 合资企业已批准钻探位于美国墨西哥湾近海的 Who Dat East 评估/勘探井和 Who Dat South 勘探井。预计这两口井的总成本将为卡隆带来 67-7700 万美元的净成本。

Who Dat East
Who Dat East 位于 Who Dat 浮式生产系统 (FPS) 以东约 27 公里处。 Who Dat East 井 MC 509-1 (LLOG) 预计将于 2024 年 4 月上半月使用 Noble Valiant 钻井船开钻。该井的目的是描绘 2001 年发现的区域，并测试中中新统部分的其他目标。

该井旨在测试五个主要油藏层段，根据结果，可能会暂停其未来潜在生产井的资格。 Who Dat East 估计包含 17 MMboe 总无风险 2C 或有资源（按净收入利息 (NRI) 计，Karoon 净值 5.4 MMboe，扣除政府和其他特许权使用费）和 35 MMboe 总无风险 2U 预期资源（10.7 MMboe） MMboe 净至 Karoon（基于 NRI 基础），总地质成功概率估计为 62%1。

该井将作为斜井钻探，总测量深度约为7,925米，钻探和评估将花费约56天。

Who Dat East 合资企业参与者包括：
LLOG（运营商） 40%
Karoon 40%
Westlawn 20%

Who Dat South
Who Dat South 勘探区位于 Who Dat FPS 西南约 11 公里处。 Who Dat South 勘探井 MC 545-1 (LLOG) 预计将使用 Seadrill West Neptune 钻井船在 CY24 第二季度末开钻。

该井的目的是测试中新世剖面的两个目标，其中较浅的目标与Who Dat的G-1井中的储层类似。 Who Dat South 勘探区估计含有 31 MMboe 的无风险 2U 远景资源总量（根据 NRI 计算，Karoon 净资源量为 7.6 MMboe），成功的地质概率估计为 52%1。

该井将以斜井方式钻探，总测量深度约为 7,425 米。预计钻探和评估需要大约 50 天的时间。

Who Dat South 合资企业参与者为：
LLOG（作业者） 40%
Karoon 30%
Westlawn 30%

2024 年资本支出指南
合资企业同意钻探 Who Dat East 和 Who Dat South 井后，Karoon 承诺的 CY24 资本支出总额增加了 67-7700 万美元，达到 117-1.34 亿美元。 Who Dat East 勘探钻探成本包括 2 比 1 费用（上限为 2,300 万美元）。

与 Who Dat West 勘探井相关的 33-4300 万美元或有资本支出（包括剩余的 1600 万美元）仍有待合资公司批准。

墨西哥湾三口井钻井计划的预计总成本为 100-1.2 亿美元，2024 年 2 月 29 日提供的所有其他指导均保持不变2。

Karoon advises that LLOG, as Operator, has confirmed that the Who Dat East and Who Dat South Joint Ventures have approved the drilling of the Who Dat East appraisal/exploration well and the Who Dat South exploration well, located offshore in the US Gulf of Mexico. The total cost of the two wells is expected to be US$67-77 million net to Karoon.

Who Dat East
Who Dat East lies approximately 27 kilometres east of the Who Dat Floating Production System (FPS). The Who Dat East well, MC 509-1 (LLOG), is expected to spud in the first half of April 2024, using the Noble Valiant drill ship. The aim of the well is to delineate a discovery made in 2001, and test additional targets in the Middle Miocene section.

The well is designed to testfive main reservoir intervals and, subjectto the results, may be suspended as a potential future producer. Who Dat East is estimated to contain 17 MMboe of gross unrisked 2C Contingent Resources (5.4 MMboe net to Karoon on a Net Revenue Interest (NRI) basis, which is after Government and other royalties) and 35 MMboe of gross unrisked 2U Prospective Resources (10.7 MMboe net to Karoon on a NRI basis), with an aggregate geological probability of success estimated to be 62%1 .

The well will be drilled as a deviated hole with a total measured depth of approximately 7,925 metres and will take approximately 56 days to drill and evaluate.

LLOG (operator) 40%
Karoon 40%
Westlawn 20%

Who Dat South
The Who Dat South prospect is located approximately 11 kilometres southwest of the Who Dat FPS. The Who Dat South exploration well, MC 545-1 (LLOG), is expected to spud towards the end of the second quarter of CY24, using the Seadrill West Neptune drill ship.

The objective of the well is to test two targets in the Miocene section, with the shallower target being similarto the reservoir in the G-1 well in Who Dat. The Who Dat South prospect is estimated to contain 31 MMboe of gross unrisked 2U Prospective Resources (7.6 MMboe net to Karoon on a NRI basis), with the geological probability of success estimated to be 52%1 .

The well will be drilled as a deviated hole with a total measured depth of approximately 7,425 metres. It is expected to take approximately 50 days to drill and evaluate.

The Who Dat South JV participants are:
LLOG (operator) 40%
Karoon 30%
Westlawn 30%

2024 Capex Guidance
Following the Joint Ventures’ agreement to drill the Who Dat East and Who Dat South wells, Karoon’s total committed capex for CY24 has increased by US$67-77 million,to US$117-134 million. The Who Dat East exploration drilling costs include a 2 for 1 carry (capped at US$23 million).

Contingent capex of US$33-43 million relating to the Who Dat West exploration well (which includes the remaining carry of US$16 million) is still subject to JV approval.

The total estimated cost of the three well Gulf of Mexico drilling program, of US$100-120 million, and all other guidance provided on 29 February 2024 is unchanged2 .
