NEW YORK, June 11 (Reuters) - U.S. liquefied natural gas company Cheniere Energy's LNG.N liquefaction midscale trains 1-6 at the Corpus Christi LNG export plant's Stage 3 expansion in Texas were on track to take in more natural gas on Thursday after shutting down on Wednesday, data from financial firm LSEG showed.

Cheniere said in a report to Texas environmental regulators that it shut the Stage 3 Midscale Trains 1-6 on Wednesday morning after the facility experienced an upset due to high LNG rundown pressure.

Officials at Cheniere were not immediately available for comment on Thursday.

• LSEG said the amount of gas flowing to Corpus was on track to rise to 2.61 billion cubic feet per day on Thursday, up from 2.14 bcfd on Wednesday and a prior seven-day average of 1.81 bcfd.

• If correct, the 2.61 bcfd of feedgas on Thursday would be the highest since flows to the plant hit a record 2.64 bcfd on January 31, according to LSEG data.

• Feedgas to the plant has been reduced since the start of June due in part to spring maintenance, energy analysts and traders said.

• When all units at Corpus are operating, the plant can turn about 3.5 bcfd of gas into LNG.

• The plant has three 0.8-bcfd trains 1-3 operating and seven 0.2-bcfd midscale trains operating and under construction.
