99.1  Press  Release  dated  March  31,  2003
BAKERSFIELD,  CA,  MARCH  31  2003  --  Tri-Valley  Corporation  (OTC  BB: TRIL)
announced today financial results for the fourth quarter and twelve months ended
December  31,  2002.

For  the  fourth  quarter 2002, total revenue increased 26% to $1.3 million from
$467,671  in  the  2001  fourth  quarter,  primarily reflecting turnkey drilling
activity  and  increased  natural gas prices.  Net income was $321,976, or $0.02
per  share,  compared with a net loss of $262,263, or $0.01 per common share, in
the  same  2001  quarter.

For  the year ended December 31, 2002, total revenue jumped 295% to $6.3 million
from $2.1 million in the prior-year period, reflecting strong oil and gas prices
and  increased  sales  of drilling prospects.  Net income was $769,130, or $0.04
per  common  share,  compared with a net loss of $117,975, or $0.00, in the same
2001  period.  Shareholder  equity  advanced 357% to $1,262,306 from $353,776 in
2001.

As  of year-end 2002, the Company benefited from higher gas prices, in which its
reserves declined to 1.5 billion cubic feet (bcf), gaining in worth with a value
of  $2.2 million, from 1.7 bcf of natural gas worth $1.0 million at lower prices
in  2001.

"Tri-Valley's  strong  revenues,  profitability  and gains in shareholder equity
clearly demonstrate the soundness and effectiveness of our vision and strategy,"
stated F. Lynn Blystone, Tri-Valley's President and Chief Executive Officer. "We
look  for  large targets where discovery success can generate multiple increases
in  our  share  price and exceptionally reward our drilling partners who are all
high  net worth individuals.  Moreover, the Bakersfield area is home to numerous
giant  fields  -- and our proprietary data indicates the potential for many more
opportunities."

In  2002,  Tri-Valley  began conducting what it believes is the largest, highest
upside  oil  and  gas  exploration  opportunity  currently  available to private
investors  in  the United States, which increased costs and expenses.  Comprised
of  26  large  prospects with an aggregate potential estimated in the range of 6
billion  barrels  of oil equivalent (BOE), the program has 23 targets around the
Company's  Bakersfield,  California  headquarters  and three targets in Nevada's
Railroad  Valley,  50  miles  southwest  of  Ely.

Tri-Valley  has  already  acquired  approximately 65,000 acres covering prospect
inventory.  Four  of the prospects have been drilled, resulting in two dry holes
and two very large discoveries of oil and gas in tight formations, which require
additional  work  to  obtain  commercial  flow  rates.

Blystone  continued,  "In  America, the responsibility for replacing the oil and
gas  reserves  of  the  nation is left to the private sector, and in many cases,
individual  investors.  The  government  provides  substantial  tax  benefits to
encourage  investors,  and  Tri-Valley  has  designed  a  program  with  bonanza
potential  to  do  its  share.

"We  intend  to  demonstrate  that  we can reverse the dependency on foreign oil
sources  and  reward all parties in the process.  While we will inevitably drill
some  dry holes in the process, we believe we will find huge discoveries for the
benefit  of  consumers,  our  shareholders  and  drilling  partners."

Blystone  concluded,  "Tri-Valley's market capitalization has grown more than 40
times  over the past seven years -- through the toughest times of both the stock
market  and  the petroleum industry.  We strongly believe that the Company's big
exploration  program positions us for even greater growth in a shorter period of
time."
