巴西石油公司在瓜希拉近海盆地发现的天然气储量估计约为 6 万亿立方英尺。巴西石油公司表示，在 Uchuva-1 和 Uchuva-2 井（现称为 Sirius-1 和 Sirius-2）发现的天然气表明哥伦比亚的天然气储量将大幅增加。

巴西石油公司拥有 44.4% 的运营权，而哥伦比亚国家石油公司拥有 55.6% 的权益，它们共同运营这些油井所在的 Tayrona 区块。Sirius-1 油井位于深水区，水深 837 米，距海岸约 32 公里，距圣玛尔塔市 76 公里。

该财团计划继续开发该地区，遵守与国家碳氢化合物管理局签订的合同协议。然而，这些储量的商业可行性还需要进一步分析和研究。Uchuva-2 评估井的钻探于 6 月开始，以评估 2022 年 7 月在 Uchuva-1 勘探井首次发现的天然气。

据路透社报道，巴西国家石油公司勘探总经理罗杰里奥·索亚雷斯表示：“Sirius 的初步构想……预计在 2029 年至 2030 年间产出第一批海上天然气，届时将有四口生产井，预计十年内日产量为 1330 万立方米。 ”他在卡塔赫纳举行的哥伦比亚石油协会 (ACP) 论坛上补充说，Sirius 项目有望成为哥伦比亚最大的海上发现，并有可能使该国的储量翻一番。

开发 Sirius 项目的总投资估计约为 50 亿美元（273.9 亿雷亚尔），其中 20 亿美元用于勘探，30 亿美元用于生产开发。彭博社援引首席执行官 Ricardo Roa 的话报道，除了 Sirius 发现的天然气外，Ecopetrol 还宣布在 Papayuela 井发现了另一个海上天然气矿藏，该矿藏的天然气产量可能高达 8 亿立方英尺/天。Roa指出，这一发现仍处于早期阶段，可以满足哥伦比亚目前 80% 的天然气需求，可能需要五到七年才能投产。Ecopetrol 是该发现的唯一运营商，该发现也位于 Tayrona 区块。

Petrobras and Ecopetrol announce major gas finds in Colombia

The finds by Brazil's Petrobras in the Guajira Offshore Basin are estimated to hold around 6 trillion f3 of gas in place. Petrobras said the discoveries at the Uchuva-1 and Uchuva-2 wells, now known as Sirius-1 and Sirius-2, indicate a substantial addition to Colombia's gas reserves.

Petrobras, with a 44.4% operatorship stake, and Ecopetrol, with a 55.6% interest, jointly operate the Tayrona block where these wells are situated. The Sirius-1 well is located in deep waters at a depth of 837 m, approximately 32 km from the coast and 76 km from Santa Marta city.

The consortium plans to continue the development of the area, adhering to the contractual agreements with the National Hydrocarbons Agency. However, the commercial viability of the reserves will require further analysis and studies. The drilling of the Uchuva-2 appraisal well began in June to evaluate the natural gas discovery initially made at the Uchuva-1 exploration well in July 2022.

Petrobras general manager for exploration Rogerio Soares, as reported by Reuters, said: “The initial conception of Sirius... foresees the first offshore gas in 2029 to 2030 with four producing wells and an expected production of 13.3 million m3/d for ten years.” The Sirius project is expected to be the largest offshore discovery in Colombia and could potentially double the nation's reserves, he added during the Colombian Petroleum Association's (ACP) forum in Cartagena.

The total investment to develop the Sirius project is estimated to be around US$5 billion (27.39 billion reais), with US$2 billion allocated for exploration and US$3 billion for production development. In addition to the Sirius discoveries, Ecopetrol has announced another offshore natural gas deposit at the Papayuela well, which could yield up to 800 million f3/d of gas, reported Bloomberg, citing CEO Ricardo Roa. This discovery, still in its early stages, could satisfy 80% of Colombia's current gas demand and may take five to seven years to become productive, Roa noted. Ecopetrol is the sole operator of the discovery, which is also located in the Tayrona block.
