Roszarubezhneft's five joint ventures now must rely on PDVSA-designated intermediaries that take a large share of the revenues for their services, the people said.
The joint ventures are owed about $3.2 billion from sales handled by PDVSA, one of the people said.
Roszarubezhneft, Russia's oil ministry, PDVSA and Venezuela's oil and foreign affairs ministries did not reply to requests for comment.
It also could help PDVSA make progress toward its goal of raising Venezuela's oil output by 40% this year.
Oil production at the five joint ventures has dwindled as U.S. sanctions have hampered investment and maintenance work, and deterred many buyers of Venezuelan crude.
