SECTION 7 - REGULATION FD

ITEM 7.01    Regulation FD Disclosure.

On July 31, 2007, South Texas  Oil  Company  provided a Corporate update to the
shareholders of the Company.  The purpose of this  Regulation FD Disclosure, is
to provide the shareholders of South Texas Oil Company a comprehensive overview
of operations to date and provide disclosure on items  the  Company  intends to
discuss with the investment community.

Corporate Update

A.  Company Overview.

Effective  June  18,  2007  the  Company  retained  the  services  of Mr. Scott
Zimmerman as President and Mr. Bill Zeltwanger as Vice-President of South Texas
Oil Company.

Mr. Scott Zimmerman

Mr.  Zimmerman,  the  former President and CEO of Storm Cat Energy (AMEX:  SCU)
holds a Bachelor of Science  in  Petroleum  Engineering.   Mr. Zimmerman has an
extensive  background  in the oil and gas industry including working  at  Huber
Corporation for 20 years  where  he  was  instrumental  in  the sale of Huber's
Fruitland  Coal  CBM  field  for  $100+  MM in profit.  In 2002, he  was  Vice-
President of Operations and Engineering for Evergreen Resources and responsible
for over 1,000+ producing wells and 800,000  prospective  acres.  Evergreen was
acquired  by  Pioneer Resources for $2.1 billion in 2004.  Mr.  Zimmerman  then
founded Storm Cat  Energy  which  is  currently  traded  on  the American Stock
Exchange.

Mr. Bill Zeltwanger

Mr  Zeltwanger  has  been involved in the industry since 1973.  He  started  in
south Texas and was then  later  involved  in parts of the Austin Chalk and has
been involved in several new Wilcox field discoveries  in  both Fayette and Lee
counties in Texas.  For the past 6 years he has been a partner  in  Leexus  Oil
and  Gas  which  recently  sold  its  assets  to  South  Texas  Oil Company for
approximately $26 million. Mr. Zeltwanger has extensive knowledge  of the field
the Company is currently drilling.

B.  Areas of Operations.

1.  Southwest Texas

   	  a.)   Netherland,   Sewell   and   Associates  recently   provided  a
	        reserve report for these leases which indicated year  end  2006
	        having a  197%  increase  in our proved developed reserves over
		a  previous  study  conducted  in  2004.   The  Reserve  report
		indicated  a  PV-10  on   the  proved  developed  reserves   of
		$860,200.  This  increase  is  attributable  to  the successful
		workover program which was initiated in early 2006.

   	  b.)   Our  workover  rig  is  scheduled  to  start  the   process  of
	        putting  over  27  wells  back  into  production that have been
	        affected  by  the  adverse weather in this area of operations.

2.  Colorado

          a.)   The  Company  has  drilled  3  wells  in  Colorado  with  a 75%
                working  interest  in  each  well.  These  wells  combined  are
		currently  averaging approximately 40 bopd (barrels of oil  pe
		day) and 305 mcfd (thousand cubic feet per day)

          b.)   The  Company  has  yet  to close on the purchase of  the 20,000
                acres under consideration due to the complexities of the  field
		and  reserve  evaluation  in  order  to have a fairness opinion
		issued.   Mr.  Zimmerman  is  in  the  final   stages  of   the
		evaluation  of  this  field  and  working  on  the  independent
		evaluation   and   issuance  of a  fairness  opinion  for   the
		transaction.

3.   South Central Texas

          a.)   The  Company  previously announced the acquisition of leasehold
                acreage,  various  working  interests  and  related  assets  in
                approximately 18,000 acres in south central Texas.  Total gross
                production  reported  with the Railroad Commission in Texas for
                these leases in December  2006 was 341 bopd and 1,020,000 cubic
                feet of gas per day.  The Company  paid  $3  million  in  cash,
                issued 2 million shares of restricted stock and provided a note
                for $4 million as consideration for the acquisition.

        	The  company  makes  the  distinction  of naming  the  existing
		producing  wells the Giddings  properties and the new  find  is
		named  the Bastrop  field.   Within  the Bastrop field there is
		Bastrop 1 which the  company  owns an 18.25%  working  interest
		and 17.4375% net royalty interest.  In Bastrop 2,  the  company
		owns  a  100%  working  interest  and  a  79% - 83% net royalty
		interest.

          b.)   A significant portion of the newly acquired acreage lies in the
                Bastrop  1   and   2   fields  which  have  the  potential  for
                approximately 100 new wells  at an average depth of 7,000 feet.
                The  Bastrop fields have production  potential  from  both  the
                Austin  Chalk  and  lower  Buda  formation.   To  date the only
                formation  that  has  been  produced  from  these wells in  the
                Bastrop 1 field is the Buda.

        Bastrop 1 Drilling Results.

        Well #1

        This first well brought into production in late December  2006  and was
        put  on  choke and flowed approximately 200 bopd, cumulative production
        through June 30 is at 29,757 BBls of oil.

        Well #2

        This well  was  completed  and put into production in June and began to
        produce oil.  The well then  began producing oil along with water.  The
        well  has  been  shut  in  as of mid-July  so  Mr.  Zimmerman  and  Mr.
        Zeltwanger can review the completion  methods  used  on  the  well  and
        recomplete this well to prevent the communication of water.

        Well #3

        This  well was completed in June 2007 and tested using 10/64, 11/64 and
        12/64 chokes  for 4-5 hours each, the well flowed an average of 21 boph
        (barrels of oil  per hour), the equivalent gross production of 504 bopd
        and 188 mcfd. Wellhead  pressure  was recorded at an average of 900lbs.
        This well was produced for 17 days  in  June with cumulative production
        through June 30 at 2,793 barrels of oil.

        Well #4

        This well has been drilled to a depth of  approximately  7,000 feet and
        will be put into production within the next 14 days.  Mr.  Zimmerman is
        currently evaluating the completion methods to use for this well.

        Well #5

        This well has been drilled to a depth of approximately 7,000  feet  and
        will  be put into production within the next 14 days.  Mr. Zimmerman is
        currently evaluating the completion methods to use for this well.

          c.)   South  Texas  Oil  Company  is  due to commence drilling of the
                sixth well in Bastrop field in the  next  14  days.   The sixth
                well is scheduled to be drilled in the Bastrop 2 acreage  where
                the  company  owns a 100% working interest and between a 79%  -
                83% net royalty interest on the leases.

          d.)   South Texas Oil  Company  recently  acquired additional oil and
                gas  interests  related  to  the  existing   working  interests
                currently held in the Giddings field for $1.8  million  in cash
                utilizing   the   Company's  credit  facility.   The  interests
                acquired  approximately   double   South  Texas  Oil's  current
                ownership  in  these  leases which South  Texas  Oil  currently
                operates to almost 100%  working  interest  and approximate 75%
                net  revenue interest.  Based on 2006 production  numbers,  the
                return  from  revenue  for  this  investment  which includes 26
                producing wells will be just over 12 months.

4.   Drilling Operations

          a.)   The Company recently purchased a drilling rig to  provide  cost
                savings and flexibility in the drilling of its own wells.

          b.)   The  Company  recently completed the drilling of its third well
                using this rig with the fourth well to commence within the next
                14 days. This fourth  well  is  to  be  our  first  well in the
                Bastrop 2 acreage.

       The initial well drilled with our rig was to a depth of 4,000  feet  and
       was not part of our Bastrop fields.  The subsequent two wells which were
       drilled are part of an initial 10 well drilling program in the Bastrop 1
       and 2 fields and were drilled to a depth of approximately 7,000 feet.

C.  Operations Summary

In  February  2007,  the  Company  was  provided  a  secured $15 million credit
facility in order to further the business strategy.  This  credit facility is a
three year revolving credit line with interest at prime plus 4 percent.

The  most  recent production reports submitted to the Rail Road  Commission  in
Texas are for  the  month of May 2007 and show gross production of 540 bopd and
1,033 mcfd for the wells operated.  Combined with our Colorado wells, the gross
production for May was  576  bopd  and 1,338 mcfd.  This shows month over month
production increases from the December 2006 production number reported with the
Rail Road Commission.

The Company continues to make progress  in  its  drilling  and  operations with
gross production increasing on a monthly basis.  The Company now  employs  over
27 people with an additional office recently opened in Bastrop, Texas.
