Over 600 US oil and gas contractors received nearly $1 billion in total loans from a federal programme meant to help small businesses stay afloat and retain jobs in the current market downturn, government data show.

Upstream recently published a searchable database of oil and gas players that may have received more than $4 billion in financing through the Trump Administration's Paycheck Protection Program, which was rolled out earlier this year.

That database did not include certain contractors because they were categorised separately.

A newer database compiled by Upstream includes companies categorised by the US Small Business Administration as "oil and gas pipeline and related structures construction" ventures. In all, 614 companies received up to $954.4 million through the programme, retaining an estimated 36,000 jobs, according to the data.

Most of the recipients appear to be construction contractors, though EnerVest Operating, which received a loan of between $5 million and $10 million, is a private operator with properties in multiple US basins.

Meanwhile, engineering consultant Netherland Sewell received a loan ranging between $2 million and $5 million.

The new database is searchable below.
