None of the West Texas producers that delivered crude oil in June and July to SemCrude before its parent company filed for bankruptcy will be paid, the attorney for some of the producers said Monday.

Terry Ronan, acting president and CEO of parent company SemGroup, sent a letter telling the producers they wouldn't be paid "despite the promises and press releases at the time of the bankruptcy," said Abilene attorney Dick Harris, who provided a copy of Ronan's letter.

"Of course, we continue our efforts to collect the amounts due through the bankruptcy court," Harris said.

Meanwhile, a Delaware bankruptcy judge is set to decide whether collapsed energy company SemGroup LP can hire temporary restructuring experts paid between $245 and $795 an hour and eligible for $7.5 million in bonuses, according to records.

SemGroup has paid a $1 million advance to the restructuring specialists from AlixPartners and its subsidiary, APS Services, documents show.

A company spokesman said last week that the sums are standard in a field that demands a particular, high-pressure kind of expertise.

The Tulsa-based company laid off 110 of its approximately 400 Tulsa workers earlier this week.

Those workers could receive up to two weeks' severance but will have to wait until federal Judge Brendan L. Shannon can sign off on the termination payout.

Founded eight years ago in Tulsa and recently considered one of the nation's biggest private firms, SemGroup filed for Chapter 11 bankruptcy protection in Wilmington, Del., on July 22.
