PGS 已将超过 4,200 平方公里的 3D 数据添加到刚果盆地深水区 33 区块的区域 MegaSurvey 数据集中。PGS 与 ANPG 合作发布的额外 4,238 平方公里 3D 数据涵盖了可通过其永久要约制度由 ANPG 直接授予的开放面积。安哥拉大型调查数据集的总覆盖范围目前超过 49 500 平方公里。

数据扩展涵盖了 33 号区块的大部分区域，该区块位于多产的 17 号和 32 号区块的外侧和南部。目前，这些区块每天从盐后寡-中新世区块生产约 55 万桶石油。33 区块仅包含 6 个渗透井，已发现两个渐新世石油，与邻近区块相比，该区块的勘探程度严重不足。

瞄准更深地层
下刚果盆地深水区尚未钻探盐下巨型层序，也很少有井测试过盐后白垩系地层。然而，对白垩纪盐后的一项此类测试已证明，33 区块的下阿尔比安老化地层中具有良好的烃源岩，具有高石油潜力。上白垩统老化油藏在下刚果盆地的陆架区域具有高产性，可以成为舷外有意义的勘探目标。33 区块位于刚果扇主要沉积中心的侧翼，是这些更深目标的有利区域。这里的覆盖层较少，由于 Loeme 地层盐的盐运动减少，地震成像的挑战也较少。

永久报价覆盖
安哥拉 MegaSurvey 还提供邻近永久报价区块 32 和 34 的 3D 数据覆盖，可以针对相同的游戏进行定位。安哥拉区域大型调查提供了利用一致、幅度和相位平衡的数据集以经济有效的方式评估这些开放区块的方法。

PGS has added over 4 200 sq. km of 3D data to its regional MegaSurvey dataset over Block 33 in the deepwater Lower Congo Basin. The additional 4 238 sq. km of 3D data released by PGS in partnership with ANPG covers open acreage that is available for direct award from ANPG through its Permanent Offer regime. Total coverage of the Angola MegaSurvey dataset now stands at over 49 500 sq. km.

The data extension covers the majority of Block 33, which is located outboard and south of the prolific blocks 17 and 32. Combined these currently produce around 550 000 barrels of oil per day from post-salt Oligo-Miocene plays. Block 33 contains just six well penetrations, which have yielded two Oligo-Miocene oil discoveries, and is highly underexplored in comparison to the neighboring acreage.

Targeting the Deeper Stratigraphy
No well in the deepwater Lower Congo Basin has yet penetrated the pre-salt megasequence and few wells have tested the post-salt Cretaceous section. One such test of the Cretaceous post-salt, however, has proven excellent source rocks with high oil potential in the Lower Albian aged stratigraphy on Block 33. Upper Cretaceous-aged reservoirs are highly productive in the shelfal areas of the Lower Congo Basin and could be meaningful exploration targets in the outboard. Block 33, located on the flank of the main Congo Fan depocenter, is a favorable area for these deeper targets. Here overburden is less, and seismic imaging challenges are fewer due to reduced halokinesis of the Loeme Formation salt.

Permanent Offer Coverage
The Angola MegaSurvey also provides 3D data coverage over neighboring Permanent Offer blocks 32 and 34, where the same plays can be targeted. The regional Angola MegaSurvey provides the means to evaluate these open blocks in a cost-effective manner utilizing a consistent, amplitude and phase-balanced dataset.
