AVIVA REPORTS ON COLOMBIAN ACTIVITIES

Aviva Petroleum Inc. ("AVP") the Dallas-based oil and gas
exploration and production company, reported results from
the development well Linda No. 5 .

In the Santana contract area in Colombia, the Linda No. 5
development well was drilled to a total depth of 9,212
feet in early May 1997.  Electric log analysis indicated
the presence of 61 feet of net oil pay in the Caballos
formation, 34 feet of net pay in the Villeta "T"
formation, and 53 feet of net pay in the Villeta "U"
formation.  All three zones were stimulated by hydraulic
fracturing, and the well was completed as a commingled
producer.  Production from the well is currently 2,500
barrels of fluid per day with a 22 per cent water cut on
an electric submersible pump.  Oil gravity
is 28.5 degree API.

Preliminary interpretation of the 3D seismic programme
acquired earlier this year over the Mary and Miraflor
areas is encouraging and several possible drilling
locations have been defined.  Application has been made
for environmental approval to drill the first well in a
new programme of exploration and development drilling.
The new programme is expected to commence in early 1998,
pending completion of interpretation of the seismic data
and receipt of governmental permits.

Aviva is engaged in the exploration for and the
development and production of oil and gas in Colombia and
offshore in the United States.  In addition to its London
Stock Exchange listing, the Companys Depository Shares
are traded on the American Stock Exchange under the
ticker symbol "AVV".
