Item 2.02      Results of Operations and Financial Condition.

               The press release by Carrizo Oil & Gas,  Inc.  (the  "Company" or
"we") dated November 11, 2004 concerning  third quarter 2004 financial  results,
furnished as Exhibit 99.1 to this report,  is incorporated by reference  herein.
The press release  contains  measures  which may be deemed  "non-GAAP  financial
measures" as defined in Item 10 of Regulation S-K of the Securities Exchange Act
of 1934, as amended. We discuss EBITDA, as defined in the press release, for the
quarters and nine months ended  September 30, 2003 and 2004. The most comparable
GAAP financial  measure,  net income,  and information  reconciling the GAAP and
non-GAAP  measures  were also  included in the press  release.  We believe  that
EBITDA, as defined, may provide additional information about our ability to meet
our future  requirements  for debt  service,  capital  expenditures  and working
capital. EBITDA, as defined, is a financial measure commonly used in the oil and
natural  gas  industry  and  should  not  be  considered  in  isolation  or as a
substitute  for  net  income,   operating  income,  cash  flows  from  operating
activities or any other measure of financial performance presented in accordance
with  generally  accepted  accounting  principles or as a measure of a company's
profitability or liquidity.  Because EBITDA, as defined,  excludes some, but not
all, items that affect net income, the EBITDA presented in the press release may
not be  comparable  to similarly  titled  measures of other  companies.  We also
discuss net income as adjusted  excluding  the  non-cash  after-tax  items stock
option  compensation  expense and equity in the loss of Pinnacle Gas  Resources,
Inc.  for the  quarter  and nine  months  ended  September  30,  2004.  The most
comparable GAAP financial measure,  net income, and information  reconciling the
GAAP and non-GAAP  measures are also included in the press  release.  We believe
that this  information  will help investors  compare results between periods and
identify  operating  trends that would  otherwise  be masked by the stock option
compensation expense and the equity in the loss of Pinnacle Gas Resources, Inc.

               None  of  the   information   furnished  in  Item  2.02  and  the
accompanying  exhibit  will be deemed  "filed" for purposes of Section 18 of the
Securities  Exchange Act of 1934,  as amended,  nor will it be  incorporated  by
reference  into any  registration  statement  filed  by the  Company  under  the
Securities Act of 1933, as amended,  unless  specifically  identified therein as
being  incorporated  therein by reference.  The furnishing of the information in
this report is not intended  to, and does not,  constitute  a  determination  or
admission by the  Company,  that the  information  in this report is material or
complete,  or that investors should consider this  information  before making an
investment decision with respect to any security of the Company.
