Jan 21 (Reuters) - U.S. liquefied natural gas (LNG) company Venture Global"s Calcasieu Pass export plant in Louisiana is close to producing its first LNG, energy traders said after the amount of feed gas to the facility increased rapidly this week. The amount of gas flowing to Calcasieu rose to 88 million cubic feet per day (mmcfd) on Friday, from an average of about 38 mmcfd during the prior week, according to pipeline data from Refinitiv. Calcasieu has been pulling in gas since around August, according to Refinitiv data, as the company tests equipment before the facility enters commercial service later in 2022. Officials at Venture Global were not immediately available for comment. Venture Global is installing 18 modular liquefaction trains configured in nine blocks at Calcasieu to produce about 10 million tonnes per annum (MTPA) of LNG, equivalent to about 1.5 billion cubic feet per day of natural gas. Analysts estimate the plant cost about $4.5 billion. Federal regulators have approved the commissioning of at least two blocks so far. read more In total, Venture Global has about 70 MTPA of LNG export capacity under construction or development in Louisiana, including the 10-MTPA Calcasieu Pass, 20-MTPA Plaquemines, 20-MTPA Delta and 20-MTPA CP2. Venture Global has already started early site work on the $8.5 billion Plaquemines project, which analysts expect to start producing first LNG in 2024. Venture Global has entered long-term agreements to sell LNG to units of several companies around the world, including China National Offshore Oil Corp (CNOOC), China Petroleum and Chemical Corp (Sinopec) (600028.SS), Royal Dutch Shell PLC (RDSa.L), BP PLC , Edison SpA (EDNn.MI), Galp Energia SGPS SA (GALP.LS), Repsol SA (REP.MC) and Polish Oil and Gas Co (PGNiG). read more
