* Halliburton's net total Venezuela investment is $265 mln

* Has $400 mln in bond guarantees related to Venezuela

SAN FRANCISCO, July 24 (Reuters) - Oilfield services provider Halliburton Co (HAL.N) laid out its financial interests in the Venezuelan market on Friday as it struggles to get paid what it is owed by state-run oil company PDVSA.

PDVSA has run up large debts with companies such as Halliburton and rival Schlumberger Ltd (SLB.N) and is trying to renegotiate tariffs with them.

In a filing with U.S. regulators on Friday, Halliburton did not discuss the amount owed, but said it invested a total of $265 million in Venezuela as of the end of June and had $400 million of surety bond guarantees outstanding relating to its operations in the country.

Surety bonds usually provide for monetary compensation in case one party fails to do what it said it would. Halliburton gave no details on the guarantees in the filing and a spokeswoman could not be reached for comment.

Earlier on Friday, Schlumberger Chief Executive Andrew Gould said on a conference call to discuss its second-quarter results that the general situation in terms of receivables and contracts in Venezuela had shown a "marked improvement."

Venezuela's oil minister said last month that PDVSA had paid $2 billion of the more than $7 billion owned to service providers at the end of 2008. [ID:nN11529406] (Reporting by Braden Reddall; editing by Andre Grenon)
