據今日石油2020年8月5日報道，美國跨國投資銀行和金融服務公司摩根士丹利表示，對蘇里南第58號區塊建模顯示，第58號區塊潛在油氣儲量高達65億桶油當量，該區塊可分7個階段開發，蘇里南目標是在2026年開采出第一批石油。

美國阿帕奇公司在蘇里南海上獲得的第3個也是最大的一個發現Kwaskwasi-1井在鉆進過程中在兩個層段內鉆遇了至少278米厚的純石油和揮發油/凝析油地層，其中坎帕階層段內鉆遇了63米厚的純石油地層和86米厚的純揮發油/凝析油地層，而在桑托價層段中鉆遇了129米厚的純油氣層。

摩根士丹利在一份研究報告中表示， “我們的蘇里南模型說明了APA的 [阿帕奇] 第58區塊的潛在價值。我們模擬了7個階段開發的65億桶油當量(59億桶石油)。我們預測第58號區塊將在2026年開采出首批石油，此后來自每個連續階段的石油產量將逐年遞增。

摩根士丹利進一步表示，“我們預計第58號區塊第一階段是一個較小的開發，其產量為5億桶油當量(4.5億桶石油)，浮式產油儲油和卸油(FPSO)裝置的日產能為12萬桶。對于接下來的每個階段，我們設想有10億桶油當量（9億桶石油)的產量，而FPSO的日產能為22萬桶。“

摩根士丹利表示，蘇里南第58區塊的開發節奏是由美國石油巨頭埃克森美孚公司在圭亞那海上斯塔布魯克區塊的計劃決定的，埃克森美孚公司在去年12月開始位于斯塔布魯克區塊的麗莎大油田一期項目的石油生產，最高日產能為12萬桶。埃克森美孚公司預計，到2026年前，在斯塔布魯克區塊的5個開發項目的石油日產量將增至75萬桶以上。到目前為止，埃克森美孚公司已經在斯塔布魯克區塊內發現了超過80億桶油當量的資源。

Suriname’s Block 58 could hold 6.5 billion barrels of oil – Morgan Stanley

US multinational investment bank and financial services company Morgan Stanley says its modelling of Suriname’s Block 58 shows that it contains a potential 6.5 billion barrels of oil equivalent resources which can be developed across seven phases with first oil targeted for 2026.

Kwaskwasi-1, Apache’s third and largest discovery offshore Suriname, encountered at least 278 meters of net oil and volatile oil/gas condensate pay across two intervals – Campanian – 63 meters of net oil pay and 86 meters of net volatile oil/gas condensate pay, and Santonian – 129 meters of net hydrocarbon pay.

“Our Suriname model illustrates potential value of APA’s [Apache] Block 58. We model 6.5 Bboe (5.9 Bbbl of oil) developed across 7 phases (MSe net asset value for APA ascribes 3 Bboe). We forecast first oil occurs in 2026, with production from each successive phase commencing in one-year increments thereafter,” the bank said in a research paper

“We assume the first phase is a smaller development of 500 MMBoe (450 MMbbls of oil) with floating production storage and offloading (FPSO) unit capacity of 120 Mbbl/d. For each following phase, we assume 1 BBoe (900 MMbbls of oil) of resource with FPSO capacity of 220 Mbbl/d,” Morgan Stanley further stated.

It said the development cadence for Block 58 is informed by US oil major ExxonMobil’s plans in the Stabroek Block offshore Guyana, where it began producing oil last December at the Liza Phase 1 Development which has a peak capacity of 120,000 bpd. Exxon expects to ramp up production to over 750,000 bpd by 2026 across 5 developments at Stabroek Block. The company has so far found more than 8 billion barrels of oil equivalent resources on the block.
