                             THE WISER OIL COMPANY
                                        
Item 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS

    COMPARISON OF QUARTERS ENDED SEPTEMBER 30, 1997 AND SEPTEMBER 30, 1996

     Revenues for the third quarter of 1997 decreased $2.4 million from the
third quarter of 1996, due primarily to reduced oil revenues and the absence of
marketable security sale gains in the third quarter of 1997.  On a BOE basis,
net production was 1,112 MBOE for the third quarter of 1997, down 96 MBOE or 8%
from the third quarter of 1996.  Oil sales for the third quarter of 1997 were
down $2.3 million from the third quarter of 1996 due to lower oil production and
lower prices received for oil sales.  Net oil production for the third quarter
of 1997 was 570,000 bbls, down 75,000 bbls or 12% from the third quarter of 1996
and the average price received for oil sales in the third quarter of 1997 was
$17.30 per bbl, down $1.64 per bbl or 9% from the third quarter of 1996.  The
decrease in oil production is attributable primarily to the sale of properties
in Michigan in the first half of 1997 and reduced production from the Wellman
Unit.  Gas sales in the third quarter of 1997 were up $1.4 million over the
third quarter of 1996 due to higher production and higher prices received for
gas sales.  Net gas production for the third quarter of 1997 was 2,911 MMcf, up
75 MMcf or 3% from the third quarter of 1996 and the average price received in
the third quarter of 1997 was $1.97 per Mcf, up $.45 per Mcf or 30% from the
third quarter of 1996.  Natural gas liquids (NGL) sales for the third quarter of
1997 were down $0.4 million from the third quarter of 1996 due primarily to
reduced production attributable to the Wellman Unit.

     Adjustments to oil and gas sales from the Company's hedging activities
resulted in a reduction of $0.3 million in oil and gas sales during the third
quarter of 1997 as compared to a reduction of $1.9 million during the third
quarter of 1996.  The Company did not have any marketable security sales gains
in the third quarter of 1997 compared to $0.8 million of gains in the third
quarter of 1996.  The Company plans to liquidate its remaining portfolio of
marketable securities during 1997.

     Production and operating expense for the third quarter of 1997 decreased
$.2 million or 3% from the third quarter of 1996.  On a BOE basis (excluding 162
MMcf and 141 MMcf of natural gas purchased for resale during the third quarter
of 1997 and 1996, respectively), production and operating expense during the
third quarter of 1997 increased to $5.91 per BOE, up 6% from $5.57 per BOE
during the third quarter of 1996.  The increase in production and operating
expense per BOE during the third quarter of 1997 is attributable primarily to
reduced production volumes without a corresponding reduction in production and
operating expense.  Depreciation, depletion and amortization ("DD&A") for the
third quarter of 1997 increased $0.4 million or 8% over the third quarter of
1996, primarily as a result of higher DD&A from Canadian oil and gas properties.
Exploration expense for the third quarter of 1997 increased $1.4 million or 171%
as compared to the third quarter of 1996, primarily as a result of higher
geological and geophysical expenses.  General and administrative expense during
the third quarter of 1997 increased $0.3 million or 17% as compared to the third
quarter of 1996, primarily as a result of higher payroll costs.  Interest
expense during the third quarter of 1997 was $1.9 million or 136% higher than
the third quarter of 1996 due to the increase in long term debt associated with
the issuance of $125 million of Senior Subordinated Notes in May 1997.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS
          (continued)

    COMPARISON OF QUARTERS ENDED SEPTEMBER 30, 1997 AND SEPTEMBER 30, 1996 
                                  (continued)

     The Company realized a net loss of $1.9 million and loss per share of $0.21
during the third quarter of 1997, compared to net income of $2.4 million and
earnings per share of $0.27 during the third quarter of 1996.  The Company's
Canadian operations incurred a net loss of $0.2 million during the third quarter
of 1997, compared to a net loss of $0.3 million during the third quarter of
1996.


   COMPARISON OF NINE MONTHS ENDED SEPTEMBER 30, 1997 AND SEPTEMBER 30, 1996

     Revenues for the first nine months of 1997 increased $1.0 million or 2%
from the first nine months of 1996, due primarily to higher oil and gas sales.
Oil and gas sales for the first nine months of 1997 were up $5.5 million over
the same period in 1996 primarily as a result of higher gas prices.  On a BOE
basis, net production was 3,556 MBOE for the first nine months of  both 1997 and
1996.  Net oil production was 1,830 Mbbls for the fist nine months of 1997, up
68 Mbbls or 3.8% over 1996.  The increase in net oil production over 1996 is
attributable primarily to the Maljamar field.  The average price received for
oil sales during the first nine months of 1997 was $18.17 per Bbl, a decrease of
$0.23 per Bbl or 1.2% from the first nine months of 1996.  Net gas production
for the first nine months of 1997 was 8,974 MMcf, down 252 MMcf or 3% from the
first nine months of 1996.  The average price received for gas sales during the
first nine months of 1997 was $2.14 per Mcf, up $0.56 per Mcf or 35% from the
first nine months of 1996.  Adjustments to oil and gas sales from the Company's
hedging activities resulted in a reduction of $2.1 million in oil and gas sales
during the first nine months of 1997 as compared to a reduction of $4.5 million
during the same period in 1996.  Marketable security sales gains were down 76%
to $1.8 million during the first nine months of 1997 compared to $7.6 million
during the first nine months of 1996.  The Company plans to liquidate its
remaining portfolio of marketable securities during 1997.  Other revenues during
the first nine months of 1997 includes a pretax gain of $1.8 million from the
sale of oil and gas properties, primarily located in Michigan.

     Production and operating expense for the first nine months of 1997
increased $1.9 million or 10% over the first nine months of 1996.  The increase
was due primarily to additional development wells completed at the Maljamar
properties and workover and repair operations at the Wellman Unit.  On a BOE
basis (excluding 463 MMcf and 410 MMcf of natural gas purchased for resale
during the first nine months of 1997 and 1996, respectively), production and
operating expense increased to $5.74 per BOE or 11% during the first nine months
of 1997 from $5.19 per BOE during the same period in 1996.  DD&A for the first
nine months of 1997 increased $1.6 million or 11% over the first nine months of
1996, primarily as a result of higher DD&A from Canadian oil and gas properties.
Exploration expense for the first nine months of 1997 increased $3.3 million or
111% as compared to the same period in 1996, primarily as a result of $1.2
million in dry hole expense for the South Lakeside prospect in Cameron Parish,
Louisiana and higher geological and geophysical expenses.  General and
administrative expense during the first nine months of 1997 was slightly higher
than the same period in 1996 due primarily to higher payroll costs.  Interest
expense during the first nine months of 1997 was up $2.5 million or 61% over the
same period in 1996 due to the increase in long term debt associated with the
issuance of $125 million of Senior Subordinated Notes in May 1997.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS
          (continued)

   COMPARISON OF NINE MONTHS ENDED SEPTEMBER 30, 1997 AND SEPTEMBER 30, 1996
                                  (continued)

     The Company realized net income of $2.3 million and earnings per share of
$0.26 during the first nine months of 1997, compared to a net loss of $1.4
million and loss per share of $0.16 during the first nine months of 1996.  The
Company's Canadian operations incurred a net loss of $3.2 million during the
first nine months of 1997, compared to a net loss of $6.2 million during the
first nine months of 1996.

     Operating cash flows during the first nine months of 1997 were $25.7
million, up $4.0 million from the first nine months of 1996 primarily as a
result of changes in working capital components.  Capital and exploration
expenditures of $58.3 million during the first nine months of 1997 were $26.5
million higher than the same period in 1996 due primarily to the $15.0 million
acquisition of oil and gas properties in Refugio and Goliad counties in Texas,
additional secondary recovery facilities at Maljamar and higher exploration
expense.  On May 21, 1997, the Company issued $125 million of 9  1/2% Senior
Subordinated Notes that are due in 2007.  The Company used $77.0 million of
proceeds from the Notes to repay all of the outstanding indebtedness under the
Credit Agreement.

NOTES TO FINANCIAL STATEMENTS

NOTE 1.   SUMMARY OF GUARANTIES OF 9 1/2% SENIOR SUBORDINATED NOTES

     In May 1997, the Company issued $125 million aggregate principal amount of
its 9 1/2% Senior Subordinated Notes due 2007 pursuant to an offering exempt
from registration under the Securities Act of 1933.  The notes are unsecured
obligations of the Company, subordinated in right of payment to all existing and
any future senior indebtedness of the Company.  The notes rank pari passu with
any future senior subordinated indebtedness and senior to any future junior
subordinated indebtedness of the Company.  The notes are fully and
unconditionally guaranteed, jointly and severally, on an unsecured, senior
subordinated basis by certain wholly owned subsidiaries of the Company (the
"Subsidiary Guarantors").  At the time of the initial issuance of the notes,
Wiser Oil Delaware, Inc., The Wiser Marketing Company, Wiser Delaware LLC,
T.W.O.C., Inc. and The Wiser Oil Company of Canada were the Subsidiary
Guarantors (the "Initial Subsidiary Guarantors").  Except for two wholly owned
subsidiaries that are inconsequential to the Company on a consolidated basis,
the Initial Subsidiary Guarantors comprise all of the Company's direct and
indirect subsidiaries.

     Sections 13 and 15(d) of the Securities Exchange Act of 1934 require
presentation of the following unaudited summarized financial information of the
Subsidiary Guarantors.  The Company has not presented separate  financial
statements and other disclosures concerning each Subsidiary Guarantor because
such information is not material to investors.  There are no significant
contractual restrictions on distributions from each of the Subsidiary Guarantors
to the Company.
