          PROPERTIES AND RECEIVES CREDIT LINE INCREASE TO $30 MILLION

Austin,  Texas - September 26, 2007 - South Texas Oil Company (OTCBB: STXX), an
independent energy company today announced that it recently acquired additional
working interests  in  south  central  Texas  for approximately $10 million and
received  an  increase  in its current credit line  from  $15  million  to  $30
million.

South Texas Oil Company's  CEO,  Murray  Conradie  stated,  "We  are pleased to
announce  this  acquisition  of  additional working interests in our Bastrop  1
field as it increases our net royalty  interest  in  the field to approximately
51%.   We are currently drilling 2 new wells per month  in  our  Bastrop  field
which is proving to be a significant new find for the Company."

The interests  acquired increase South Texas Oil's current net royalty interest
in the acquired  leases  by  37.5%.  The  acquisition was funded by paying $7.5
million  in  cash,  issuing a promissory note  for  $1.5  million  and  issuing
restricted shares valued at $1 million.

"We are extremely proud  to  announce  this  increase  in our credit line as it
shows  the  increasing  confidence  our  lender has in our operations  and  the
company's long term strategy.  This line will  be used to accelerate additional
growth  by  drilling  more wells, adding to our executive  team  and  continued
growth of the Company," concluded Murray Conradie.
