Exhibit 99.1

                       PRO FORMA FINANCIAL INFORMATION OF
                             SNYDER OIL CORPORATION


      The unaudited pro forma condensed  consolidated  financial  statements set
forth the  financial  position  of the  Company  as of March 31,  1996,  and the
results of  operations  for the three months ended March 31, 1996,  and the year
ended December 31, 1995, adjusted for certain significant transactions discussed
below.  The pro forma  financial  statements are based upon the  assumptions set
forth in the accompanying  notes to such statements.  The pro forma  adjustments
are based upon available  information and assumptions  that management  believes
are reasonable under the circumstances.

      The pro forma financial statements comprise historical financial data that
have been  retroactively  adjusted  or  combined  to  reflect  the effect of the
transactions  discussed  below on the  historical  financial  statements  of the
Company.  The pro forma condensed  consolidated balance sheet at March 31, 1996,
and the related pro forma condensed consolidated statement of operations for the
three months then ended and the year ended  December 31, 1995,  were prepared as
if the  transactions  were  consummated on March 31, 1996,  January 1, 1996, and
January 1, 1995, respectively. The pro forma financial statements should be read
in  conjunction  with the related  historical  financial  statements and are not
necessarily  indicative of the results that would have actually occurred had the
transactions  been consummated on the dates or for the periods  indicated or the
results which may occur in the future.

Pro Forma Divested Interests:

      During  1995,  the  Company  sold  the  majority  of  its  Wattenberg  gas
facilities in two separate  transactions and sold certain oil and gas properties
in West  Texas for a total of  approximately  $96.3  million.  In May 1996,  the
Company sold a 45% interest in the  Company's  Piceance  Project for $22 million
and a joint venture to further  develop the  properties  was agreed upon.  These
transactions  have  been  reflected  in the  accompanying  unaudited  pro  forma
condensed consolidated financial statements as "pro forma divested interests."

Pro Forma Acquired Interests:

      Between  September  and December  1995,  the Company  consummated  several
transactions in which 18,220 additional common shares of DelMar Petroleum,  Inc.
("DelMar") were acquired (raising the Company's  interest from approximately 50%
to 65%) primarily in exchange for the Company's  common stock.  The Company also
purchased  additional  interests in oil and gas  properties  operated by DelMar,
again  primarily in exchange  for the  Company's  common  stock.  In total,  the
Company  issued  1,083,271  shares of common stock at an average price of $12.03
per share. These transactions have been reflected in the accompanying  unaudited
pro forma  condensed  consolidated  financial  statements as "pro forma acquired
interests."

Pro Forma GOG Acquisition:

      On May 2, 1996, SOCO consolidated (the "Merger") its Wattenberg operations
with Gerrity Oil & Gas Corporation  ("GOG").  As a result,  SOCO will own 70% of
the  common  stock and the former  GOG  shareholders  will own 30% of the common
stock  of a  new  public  company  which  will  be  known  as  Patina  Oil & Gas
Corporation.  The Merger will be  accounted  for by the Company as a purchase of
GOG.  The Merger has been  reflected  in the  accompanying  unaudited  pro forma
condensed consolidated financial statements as "pro forma GOG acquisition."

(a)  To reflect the sale of a 45%  interest in the  Company's  Piceance  Project
     with proceeds being used to reduce long-term debt.

(b)  To reflect the  acquisition  of GOG,  including  the  elimination  of GOG's

     bank credit facility.

(d)  To reflect the excess of fair market  value  received  over the  historical

     non-cash tax effects of approximately  $24.8 million recognized as a result
     of the Merger.

STATEMENTS OF OPERATIONS

   Certain  items have been  excluded in the  accompanying  pro forma  condensed
consolidated  statements of operations due to their non-recurring  nature. These
items are  adjustments  to reflect the excess of fair market value received over

related  non-cash tax effects of  approximately  $24.8  million  recognized as a
result of the Merger.

(e)  To reflect  the  revenue and expense  items  attributable  to the  divested
     interests.

(f)  To adjust  depletion,  depreciation  and  amortization  to the amount which
     would have been provided.

(g)  To  reflect  the  revenue,   direct   operating   expenses  and  depletion,
     depreciation and amortization attributable to the acquired interest.

(h)  To reflect the earnings  attributable to the purchase of additional  common
     shares of a consolidated subsidiary.

(i)  To reflect the reduction in direct operating and general and administrative

     obligated  to  purchase  any  Notes  put to GOG at a  price  of 101% of the
     principal amount thereof upon certain asset sales or dispositions. For each
     $10 million  change in the amount of Notes  refinanced,  pro forma interest
     expense and income from continuing  operations would change by $119,000 and
     $77,000 for the three  months  ended  March 31,  1996 and by  $475,000  and
     $308,000 for the year ended December 31, 1995, respectively.
