A company owned by the family of EnQuest chief executive Amjad Bseisu bought £7million worth of new shares in the London-listed oil firm.
EnQuest said last month that it would introduce 356.7million new shares at a price of 23p in an effort to raise £82million.
The cash would go towards its flagship Kraken field development in the North Sea.
EnQuest said today it had received acceptances for 233.85million of the shares, 65.6% of the total, by the time the offer closed on Wednesday.
The firm said the remaining 122.88million were taken up pursuant to the placing.
Double A, a company controlled by the extended family of Mr Bseisu, bought 31.7million of the new ordinary shares.
Subject to the admission becoming effective, Double A will hold 8.9% of EnQuest.
Mr Bseisu previously said he was ready to buy up to £40million worth of new shares, matching the pro-rata commitments of existing shareholders.
Also this week, EnQuest creditors and the UK Companies Court approved a key component of the firm’s restructuring plans.
It now needs the approval of US courts.
The company has said its debt restructuring proposals would add £195million to the balance sheet and extend final repayment until 2021.
EnQuest had net debts of £1.38billion as of June 30, 2016.
EnQuest had been in talks with Israeli firm Delek Group over a farm-out on Kraken, only for the deal to collapse mid-September.
