Houston Oil Trust said that independent 
petroleum engineers completed an annual study that estimates 
the trust's future net revenues from total proved reserves at 
88 mln dlrs and its discounted present value of the reserves at 
64 mln dlrs. 
    Based on the estimate, the trust said there may be no money 
available for cash distributions to unitholders for the 
remainder of the year. 
    It said the estimates reflect a decrease of about 44 pct in 
net reserve revenues and 39 pct in discounted present value 
compared with the study made in 1985.

Saudi riyal interbank deposits were 
steady at yesterday's higher levels in a quiet market. 
    Traders said they were reluctant to take out new positions 
amidst uncertainty over whether OPEC will succeed in halting 
the current decline in oil prices. 
    Oil industry sources said yesterday several Gulf Arab 
producers had had difficulty selling oil at official OPEC 
prices but Kuwait has said there are no plans for an emergency 
meeting of the 13-member organisation. 
    A traditional Sunday lull in trading due to the European 
weekend also contributed to the lack of market activity. 
    Spot-next and one-week rates were put at 6-1/4, 5-3/4 pct 
after quotes ranging between seven, six yesterday. 
    One, three, and six-month deposits were quoted unchanged at 
6-5/8, 3/8, 7-1/8, 6-7/8 and 7-3/8, 1/8 pct respectively. 
    The spot riyal was quietly firmer at 3.7495/98 to the 
dollar after quotes of 3.7500/03 yesterday.

Deputy oil ministers from six Gulf 
Arab states will meet in Bahrain today to discuss coordination 
of crude oil marketing, the official Emirates news agency WAM 
reported. 
    WAM said the officials would be discussing implementation 
of last Sunday's agreement in Doha by Gulf Cooperation Council 
(GCC) oil ministers to help each other market their crude oil. 
    Four of the GCC states - Saudi Arabia, the United Arab 
Emirates (UAE), Kuwait and Qatar - are members of the 
Organiaation of Petroleum Exporting Countries (OPEC) and some 
face stiff buyer resistance to official OPEC prices.
