Garden Banks Pipeline

Last updated

The Garden Banks Pipeline is a 30-inch diameter natural gas transmission pipeline [1] which gathers gas from the offshore Gulf of Mexico and brings it into Enbridge Pipelines UTOS system, which leads into various locations in Louisiana and Texas. One end of the pipeline originates from Cameron, Louisiana, and it spans for 50 miles (80 kilometres). [2] Since 2005, the pipeline itself is 100% owned by Enbridge Offshore (Gas Transmission) L.L.C., [3] a subsidiary of the multinational pipeline company Enbridge, which has the longest pipeline system in North America. Its FERC code is 148. [4] According to the FERC website, the company total cost for pipeline operations in the 2022 fiscal year was $60,318, 949. [5]

Location

The Garden Banks Gas Pipeline is located entirely within the Gulf of Mexico, extending from Garden Banks Block 128 to South Marsh Island Block 76, [6] and intersects with four existing pipelines to move gas onshore. The Garden Banks 72 platform is a base for gathering deepwater production from the Garden Banks area, and acts as a junction platform connecting both the Cameron Highway Oil Pipeline and the Poseidon Oil Pipeline System. [7]

Garden Banks makes up just one component of the 26,000 miles of oil and gas pipelines on the Gulf of Mexico's seafloor. [8] The region is home to one of the most developed oil and gas industry sectors in the world.

Process

Garden Banks transports natural gas from the Cardamom field [owned by Shell], a reservoir about 360 kilometres (220 miles) southwest of New Orleans, and 4 miles below the sea floor. The gas is drilled via the Auger tension leg platform [located in Garden Banks Block 428], which is owned by the Royal Dutch Shell company. [9] It has a capacity of transporting one billion cubic feet of gas per day.

The Federal Energy Regulatory Commission (FERC) is an independent agency of the United States government that regulates the interstate transmission and wholesale sale of electricity and natural gas and regulates the prices of interstate transport of petroleum by pipeline.

<span class="mw-page-title-main">Oil platform</span> Offshore ocean structure with oil drilling and related facilities

An oil platform is a large structure with facilities to extract and process petroleum and natural gas that lie in rock formations beneath the seabed. Many oil platforms will also have facilities to accommodate the workers, although it is also common to have a separate accommodation platform bridge linked to the production platform. Most commonly, oil platforms engage in activities on the continental shelf, though they can also be used in lakes, inshore waters, and inland seas. Depending on the circumstances, the platform may be fixed to the ocean floor, consist of an artificial island, or float. In some arrangements the main facility may have storage facilities for the processed oil. Remote subsea wells may also be connected to a platform by flow lines and by umbilical connections. These sub-sea facilities may include one or more subsea wells or manifold centres for multiple wells.

Enbridge Inc. is a Canadian multinational pipeline and energy company headquartered in Calgary, Alberta, Canada. Enbridge owns and operates pipelines throughout Canada and the United States, transporting crude oil, natural gas, and natural gas liquids, and also generates renewable energy. Enbridge's pipeline system is the longest in North America and the largest oil export pipeline network in the world. Its crude oil system consists of 28,661 kilometres of pipelines. Its 38,300 kilometre natural gas pipeline system connects multiple Canadian provinces, several US states, and the Gulf of Mexico. The company was formed by Imperial Oil in 1949 as the Interprovincial Pipe Line Company Limited to transport Alberta oil to refineries. Over time, it has grown through acquisition of other existing pipeline companies and the expansion of their projects.

<span class="mw-page-title-main">Offshore oil and gas in the Gulf of Mexico (United States)</span> Major petroleum-producing area

Offshore oil and gas in the Gulf of Mexico is a major source of oil and natural gas in the United States. The western and central Gulf of Mexico, which includes offshore Texas, Louisiana, Mississippi, and Alabama, is one of the major petroleum-producing areas of the United States. Oil production from US federal waters in the Gulf of Mexico reached an all-time annual high of 1.65 million barrels per day in 2017. Oil production is expected to continue the upward trend in 2018 and 2019, based on ten new oil fields which are planned to start production in those years. According to the Energy Information Administration, "Gulf of Mexico federal offshore oil production accounts for 15% of total U.S. crude oil production and federal offshore natural gas production in the Gulf accounts for 5% of total U.S. dry production."
