RIDGEWOOD ENERGY W FUND, LLCNOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

1.     Organization and Purpose

The
Ridgewood Energy W Fund, LLC (the Fund), a Delaware limited liability
company, was formed on May 17, 2007 and operates pursuant to a limited
liability company agreement (the LLC Agreement) dated as of June 15, 2007 by
and among Ridgewood Energy Corporation (the Manager), and the shareholders of
the Fund. The Fund was organized to acquire interests in oil and natural gas
properties located in the United States offshore waters of Texas, Louisiana and
Alabama in the Gulf of Mexico. During the third quarter 2008, the Fund began
earning revenue and as a result was determined by the Manager to no longer be
an exploratory stage enterprise.

The
Manager has direct and exclusive control over the management of the Funds
operations. With respect to project investments, the Manager locates potential
projects, conducts appropriate due diligence and negotiates and completes the
transactions in which the investments are made. The Manager performs, or
arranges for the performance of, the management, advisory and administrative
services required for Fund operations. Such services include, without
limitation, the administration of shareholder accounts, shareholder relations
and the preparation, review and dissemination of tax and other financial
information. In addition, the Manager provides office space, equipment and
facilities and other services necessary for Fund operations. The Manager also
engages and manages the contractual relations with unaffiliated custodians,
depositories, accountants, attorneys, broker-dealers, corporate fiduciaries,
insurers, banks and others as required. See Notes 2, 6 and 8.

2.     Summary of Significant
Accounting Policies

Basis of PresentationThese unaudited
interim condensed financial statements have been prepared by the Funds
management in accordance with accounting principles generally accepted in the
United States of America (GAAP) and in the opinion of management, contain all
adjustments (consisting of only normal recurring adjustments) necessary to
present fairly the Funds financial position, results of operations and cash
flows for the periods presented. Certain information and note disclosures
normally included in annual financial statements prepared in accordance with
GAAP have been omitted in these unaudited interim condensed financial statements.
The results of operations, financial position, and cash flows for the periods
presented herein are not necessarily indicative of future financial results.
These unaudited interim condensed financial statements should be read in
conjunction with the Funds December 31, 2008 financial statements and notes
thereto included in the Funds Annual Report on Form 10-K filed with the
Securities and Exchange Commission (SEC). The year-end condensed balance
sheet data was derived from audited financial statements, but does not include
all disclosures required by GAAP.

Use of EstimatesThe preparation
of financial statements in conformity with GAAP requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities as of the date
of the financial statements and the reported amounts of revenue and expense
during the reporting period. On an ongoing basis, the Manager reviews its
estimates, including those related to property balances, determination of
proved reserves, impairments and asset retirement obligations. Actual results
may differ from those estimates.

investments with maturities, when purchased, of three months or less, are
considered cash and cash equivalents. At times, bank deposits may be in excess
of federally insured limits. At March 31, 2009 bank balances exceeded federally
insured limits by $9.9 million, of which $9.7 million was invested in money
market accounts that invest solely in U.S. Treasury bills and notes. Effective
October 2008 through December 31, 2009, federally insured limits have been
increased from $0.1 million to $0.25 million for interest bearing deposits.
Additionally, non-interest bearing deposits are fully insured during this
period.

Investments in Marketable SecuritiesAt times the Fund
may invest in U.S. Treasury bills and notes. These investments are considered
short-term when their maturities are greater than three months and one year or
less, and long-term when their maturities are greater than one year. At March
31, 2009 and December 31, 2008, the Fund had short-term held-to-maturity
investments totaling $13.1 million and $13.0 million, respectively.
Held-to-maturity investments are those securities that the Fund has the ability
and intent to hold until maturity, and are recorded at cost plus accrued
income, adjusted for the amortization of premiums and discounts, which
approximates fair value. The short-term held-to-maturity investments held at
March 31, 2009 mature during the second quarter of 2009.

For
all investments, interest income is accrued as earned and amortization of
premium or discount, if any, is included in interest income.

Salvage FundThe Fund deposits
in a separate interest-bearing account, or a salvage fund, money to provide for
the dismantling and removal of production platforms and facilities and plugging
and abandoning its wells at the end of their useful lives, in accordance with
applicable federal and state laws and regulations. At March 31, 2009, the Fund
had a held-to-maturity investment within its salvage fund totaling $1.0
million, which matures in February 2012.

Interest
earned on the account will become part of the salvage fund. There are no legal
restrictions on withdrawals from the salvage fund.

Oil and Gas PropertiesThe Fund invests
in oil and gas properties, which are operated by unaffiliated entities that are
responsible for drilling, administering and producing activities pursuant to
the terms of the applicable operating agreements with working interest owners.
The Funds portion of exploration, drilling, operating and capital equipment
expenditures is billed by operators.

The
successful efforts method of accounting for oil and gas producing activities is
followed. Acquisition costs are capitalized when incurred. Other oil and gas
exploration costs, excluding the costs of drilling exploratory wells, are
charged to expense as incurred. The costs of drilling exploratory wells are
capitalized pending the determination of whether the wells have discovered
proved commercial reserves. If proved commercial reserves have not been found,
exploratory drilling costs are expensed to dry-hole expense. Costs to develop
proved reserves, including the costs of all development wells and related
facilities and equipment used in the production of oil and gas, are
capitalized. Expenditures for ongoing repairs and maintenance of producing
properties are expensed as incurred.

Upon
the sale or retirement of a proved property, the cost and related accumulated
depletion and amortization will be eliminated from the property accounts, and
the resultant gain or loss is recognized. Upon the sale or retirement of an
unproved property, gain or loss on the sale is recognized. The Manager does not
currently intend to sell any of the Funds property interests.

Capitalized
acquisition costs of producing oil and gas properties are depleted by the
units-of-production method.

As
of March 31, 2009 and December 31, 2008, amounts recorded in due to operators
totaling $1.4 million and $4.1 million, respectively, related to capital
expenditures for oil and gas properties.

Advances to Operators for Working
Interests and ExpendituresThe Funds
acquisition of a working interest in a well or a project requires it to make a
payment to the seller for the Funds rights, title and interest. The Fund may
be required to advance its share of estimated cash expenditures for the
succeeding months operation. The Fund accounts for such payments as advances
to operators for working interests and expenditures. As drilling costs are
incurred, the advances are reclassified to unproved properties.

Asset Retirement ObligationsFor oil and gas
properties, there are obligations to perform removal and remediation activities
when the properties are retired. When a project reaches drilling depth and is
determined to be either proved or dry, an asset retirement obligation is
incurred. Plug and abandonment costs associated with unsuccessful projects are
expensed as dry-hole costs. The following table presents changes in asset
retirement obligations for the three months ended March 31, 2009 and the year
ended December 31, 2008.

As
indicated above, the Fund maintains a salvage fund to provide for the funding
of future asset retirement obligations.

Syndication CostsSyndication costs
are direct costs incurred by the Fund in connection with the offering of the
Funds shares, including professional fees, selling expenses and administrative
costs payable to the Manager, an affiliate of the Manager and unaffiliated
broker-dealers, which are reflected on the Funds balance sheet as a reduction
of shareholders capital.

Revenue Recognition and ImbalancesOil and gas
revenues are recognized when oil and gas is sold to a purchaser at a fixed or
determinable price, when delivery has occurred and title has transferred, and
if collectibility of the revenue is probable.

The
Fund uses the sales method of accounting for gas production imbalances. The
volumes of gas sold may differ from the volumes to which the Fund is entitled
based on its interests in the properties. These differences create imbalances
that are recognized as a liability only when the properties estimated
remaining reserves net to the Fund will not be sufficient to enable the
under-produced owner to recoup its entitled share through production. The
Funds recorded liability, if any, would be reflected in other liabilities. No
receivables are recorded for those wells where the Fund has taken less than its
share of production. At March 31, 2009 and December 31, 2008, there were no
material oil or gas balancing arrangements between the Fund and other working
interest owners.

Impairment of Long-Lived AssetsThe Fund reviews
the value of its oil and gas properties whenever management determines that
events and circumstances indicate that the recorded carrying value of
properties may not be recoverable. Impairments of producing properties are
determined by comparing future net undiscounted cash flows to the net book
value at the end of each period. If the net book value exceeds the future net
undiscounted cash flows, the carrying value of the property is written down to
fair value, which is determined using net discounted future cash flows from
the producing property. Different pricing assumptions, reserve estimates or
discount rates could result in a different calculated impairment. The Fund
provides for impairments on unproved properties when it determines that the
property will not be developed or a permanent impairment in value has occurred.
Given the volatility of oil and gas prices, it is reasonably possible that the
Funds estimate of discounted future net cash flows from proved oil and gas
reserves could change in the near term. If oil and gas prices decline significantly,
even if only for a short period of time, it is possible that write-downs of oil
and gas properties could occur.

Depletion and AmortizationDepletion and
amortization of the cost of proved oil and gas properties are calculated using
the units-of-production method. Proved developed reserves are used as the base
for depleting capitalized costs associated with successful exploratory well
costs. The sum of proved developed and proved undeveloped reserves is used as
the base for depleting or amortizing leasehold acquisition costs, the costs to
acquire proved properties and platform and pipeline costs. The Fund began
production in August 2008.

Income TaxesNo provision is
made for income taxes in the financial statements. The Fund is a limited
liability company, and as such, the Funds income or loss is passed through and
included in the tax returns of the Funds shareholders.

Income and Expense AllocationProfits and
losses are allocated 85% to shareholders in proportion to their relative
capital contributions and 15% to the Manager, except for interest income and
certain expenses such as dry-hole costs, trust fees, depletion and
amortization, which are allocated 99% to shareholders and 1% to the Manager.

3.     Recent
Accounting Standards

In
December 2008, the SEC issued Release No. 33-8995, Modernization of Oil and
Gas Reporting, amending oil and gas reporting requirements under Rule 4-10 of
Regulation S-X and Industry Guide 2 in Regulation S-K. The new requirements
provide for consideration of new technologies in evaluating reserves, allow
companies to disclose their probable and possible reserves to investors, report
oil and gas reserves using an average price based on the prior 12-month period
rather than year-end prices, and revise the disclosure requirements for oil and
gas operations. The final rules are effective for fiscal years ending on or
after December 31, 2009.

7

---



In
September 2006, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standard No. 157, Fair Value Measurements,
(SFAS No.157), which applies under most other accounting pronouncements that
require or permit fair value measurements. SFAS No. 157 provides a common
definition of fair value as the price that would be received to sell an asset
or paid to transfer a liability in a transaction between market participants.
The new standard also provides guidance on the methods used to measure fair
value and requires expanded disclosures related to fair value measurements.
SFAS No. 157 had originally been effective for financial statements issued for
fiscal years beginning after November 15, 2007, however the FASB has agreed on
a one year deferral for all non-financial assets and liabilities. On January 1,
2008, the Fund adopted SFAS No. 157 for financial assets and liabilities.

4.     Unproved Properties -
Capitalized Exploratory Well Costs

Leasehold
acquisition and exploratory drilling costs are capitalized pending
determination of whether the well has found proved reserves. Unproved
properties are assessed on a quarterly basis by evaluating and monitoring if
sufficient progress is made on assessing the reserves. At March 31, 2009, the
Fund had no capitalized exploratory well costs in excess of one year. The
following table reflects the net changes in unproved properties for the three
months ended March 31, 2009 and the year ended December 31, 2008.

Capitalized
exploratory well costs are expensed as dry-hole costs in the event that
reserves are not found or are not in sufficient quantities to complete the well
and develop the field. Dry-hole costs are detailed in the following table.

5.     Distributions

Distributions
to shareholders are allocated in proportion to the number of shares held.
Certain shares have early investment incentive and advance distribution rights,
as defined in the LLC Agreement, which range from approximately $8 thousand to
$16 thousand per share. The Fund began making distributions to eligible early
investors during the fourth quarter of 2008.

The
Manager determines whether available cash from operations, as defined in the
LLC Agreement, is to be distributed. Such distributions are allocated 85% to
the shareholders and 15% to the Manager, as required by the LLC Agreement.

Available
cash from dispositions, as defined in the LLC Agreement, will be paid 99% to
shareholders and 1% to the Manager until the shareholders have received total
distributions equal to their capital contributions. After shareholders have
received distributions equal to their capital contributions, 85% of available
cash from dispositions will be distributed to shareholders and 15% to the
Manager.

---



6.     Related Parties

The
LLC Agreement provides that the Manager render management, administrative and
advisory services. For such services, the Manager is paid an annual management
fee, payable monthly, of 2.5% of total capital contributions, net of cumulative
dry-hole and related well costs incurred by the Fund. Management fees for each
of the three months ended March 31, 2009 and 2008 were $0.4 million.

At
times, short-term payables and receivables, which do not bear interest, arise
from transactions with affiliates in the ordinary course of business. At March
31, 2009 and December 31, 2008, there were no such amounts outstanding.

None
of the compensation paid to the Manager has been derived as a result of arms
length negotiations.

The
Fund has working interest ownership in certain projects to acquire and develop
oil and natural gas projects with other entities that are likewise managed by
the Manager.

7.     Fair Value of Financial
Instruments

At
March 31, 2009 and December 31, 2008, cash and cash equivalents, short-term
investments in marketable securities, production receivable, salvage fund and
accrued expenses are recorded at cost, which approximates fair value due to
their short-term nature.

8.     Commitments and Contingencies

Capital CommitmentsThe Fund has
entered into multiple agreements for the drilling and development of its
investment properties. The estimated capital expenditures associated with these
agreements vary depending on the stage of development on a property-by-property
basis. As of March 31, 2009, the Fund had committed to spend an additional
$18.3 million related to its investment properties.

Environmental ConsiderationsThe exploration
for and development of oil and natural gas involves the extraction, production
and transportation of materials which, under certain conditions, can be
hazardous or cause environmental pollution problems. The Manager and operators
of the Funds properties are continually taking action they believe appropriate
to satisfy applicable federal, state and local environmental regulations and do
not currently anticipate that compliance with federal, state and local
environmental regulations will have a material adverse effect upon capital
expenditures, results of operations or the competitive position of the Fund in
the oil and gas industry. However, due to the significant public and
governmental interest in environmental matters related to those activities, the
Manager cannot predict the effects of possible future legislation, rule
changes, or governmental or private claims. At March 31, 2009 and December 31,
2008, there were no known environmental contingencies that required the Fund to
record a liability.

Insurance CoverageThe Fund is
subject to all risks inherent in the exploration for and development of oil and
gas. Insurance coverage as is customary for entities engaged in similar
operations is maintained, but losses may occur from uninsurable risks or
amounts in excess of existing insurance coverage. The occurrence of an event
that is not insured or not fully insured could have an adverse impact upon
earnings and financial position. Moreover, insurance is obtained as a package
covering all of the funds managed by the Manager. Claims made by other funds
can reduce or eliminate insurance for the Fund.

ITEM 2. MANAGEMENTS DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Cautionary Statement Regarding Forward-Looking Statements

Certain
statements in this Quarterly Report on Form 10-Q (Quarterly Report) and the
documents Ridgewood Energy W Fund, LLC (the Fund) has incorporated by
reference into this Quarterly Report, other than purely historical information,
including estimates, projections, statements relating to the Funds business
plans, strategies, objectives and expected operating results, and the
assumptions upon which those statements are based, are forward-looking
statements based on current expectations and assumptions that are subject to
risks and uncertainties that may cause actual results to differ materially from
the forward-looking statements. These forward-looking statements generally are
identified by the words believe, project, expect, anticipate,
estimate, intend, strategy, plan, target, pursue,
may, will likely
result, and similar expressions. Examples of such events that could cause
actual results to differ materially from historical results or those
anticipated include weather conditions, such as hurricanes, changes in market
conditions affecting the pricing of oil and natural gas, the cost and
availability of equipment, and changes in governmental regulations. The Fund
undertakes no obligation to update or revise publicly any forward-looking
statements, whether as a result of new information, future events or otherwise,
except as required by law.

Critical Accounting Policies and Estimates

The
following discussion and analysis of the Funds financial condition and
operating results is based on its financial statements. The preparation of this
Quarterly Report requires the Fund to make estimates and assumptions that
affect the reported amount of assets and liabilities, disclosure of contingent
assets and liabilities at the date of the Funds financial statements, and the
reported amount of revenue and expenses during the reporting period. Actual
results may differ from those estimates and assumptions. See Notes to
Unaudited Condensed Financial Statements in Part I of this Quarterly Report
for a presentation of the Funds significant accounting policies. No changes
have been made to the Funds critical accounting policies and estimates
disclosed in its 2008 Annual Report on Form 10-K.

Overview of the Funds Business

The
Fund is a Delaware limited liability company formed on May 17, 2007 to acquire
interests primarily in oil and natural gas properties located in the United
States offshore waters of Texas, Louisiana and Alabama in the Gulf of Mexico.
Ridgewood Energy Corporation (Ridgewood Energy or the Manager) a Delaware
corporation, is the Manager. As the Manager, Ridgewood Energy has direct and
exclusive control over the management of the Funds operations. The Funds
primary investment objective is to generate cash for distribution to its
shareholders through the acquisition of working interests in the exploration,
production and sale of oil and natural gas.

The
Manager performs certain duties on the Funds behalf including the evaluation
of potential projects for investment and ongoing management, administrative and
advisory services associated with these projects. For these services, the
Manager receives an annual management fee equal to 2.5% of capital
contributions, net of cumulative dry-hole and related well costs incurred by
the Fund, payable monthly. The Fund does not currently, nor is there any plan to
operate any project in which the Fund participates. The Manager enters into
operating agreements with third-party operators for the management of all
exploration, development and producing operations, as appropriate. The Manager
also participates in distributions.

Business Update

The
Fund owns working interests and has participated in the drilling of nine wells,
one is currently drilling, four have been determined to be successful and four
have been determined to be dry holes, one of which was during the first quarter
of 2009.

Currently DrillingAjax
ProjectIn
December 2008, the Fund acquired a 12.5% working interest in the Ajax Project,
an exploratory well, from Newfield Exploration Company (Newfield), the
operator. The Ajax Project began drilling in January 2009 and results are
expected during the second quarter of 2009. Through March 31, 2009, the Fund
has spent $3.8 million related to this property, for which the total estimated
budget is $15.7 million.

Successful ProjectsCobalt
ProjectIn August
2008, the Fund acquired a 5.0% working interest in the Cobalt Project, an
exploratory well, from Newfield, the operator. The Cobalt Project was
determined to be a commercial success in January 2009 and completion efforts

Three months ended March 31, 2009
compared to the Three months ended March 31, 2008

Oil and Gas Revenue. Oil and gas revenue for the three months
ended March 31, 2009 was $0.5 million related to the Main Pass 283/279 and West
Cameron 57 properties, which commenced production in August 2008 and December
2008, respectively. Prior to August 2008, the Fund had no producing wells, and
therefore had no operating revenue and was considered an exploratory stage
enterprise. During the three months ended March 31, 2009 the Funds wells sold
4 thousand barrels of oil at an average price of $40.85 per barrel and 63
thousand mcf of gas at an average price of $4.37 per mcf. During the three
months ended March 31, 2009 the Funds wells earned processing revenue totaling
$39 thousand.

Depletion and Amortization. Depletion and amortization for the three
months ended March 31, 2009 was $1.0 million. The Funds wells began production
in August 2008. Prior to that time, the Fund did not have production and
therefore did not record any depletion or amortization.

Dry-hole Costs. Dry-hole costs are those costs incurred to
drill and develop a well that is ultimately found to be incapable of producing
either oil or natural gas in sufficient quantities to justify completion of the
well. The following table summarizes dry-hole costs, inclusive of plug and
abandonment costs, for the three months ended March 31, 2009 and 2008.

Accounting
fees represent annual audit and tax preparation fees, quarterly reviews and
filing fees incurred by the Fund. Insurance expense represents premiums related
to producing well and control of well insurance, which varies dependent upon

Interest Income. Interest income is comprised of interest earned on money market
accounts and investments in U.S. Treasury securities. Interest income for the
three months ended March 31, 2009 was $0.1 million, a $0.2 million decrease
from the three months ended March 31, 2008. The decrease was the result of a reduction in average
outstanding balances earning interest, due to ongoing capital expenditures for
oil and gas properties, coupled with lower interest rates earned.

Capital Resources and Liquidity

Operating Cash FlowsCash flows used
in operating activities for the three months ended March 31, 2009 were $18 thousand,
primarily related to payments for management fees of $0.4 million, general and
administrative expenses of $0.1 million and operating expenses of $0.1 million,
partially offset by revenue received of $0.4 million and favorable working
capital of $0.1 million.

Cash
flows used in operating activities for the three months ended March 31, 2008
were $0.3 million, primarily related to management fees of $0.4 million,
general and administrative expenses of $0.1 million and payments of investment
fees of $0.1 million, partially offset by interest income received of $0.3
million.

Investing Cash FlowsCash flows used
in investing activities for the three months ended March 31, 2009 were $6.3
million primarily related to capital expenditures for oil and gas properties.
Additionally, the Fund increased its salvage fund investments by $5 thousand,
which consisted of the interest earned on this account.

Cash
flows used in investing activities for the three months ended March 31, 2008
were $3.1 million related to capital expenditures for oil and gas properties of
$2.1 million and salvage fund investments totaling $1.0 million. Additionally,
the Fund increased its salvage fund investments by $3 thousand, which consisted
of the interest earned on this account.

Financing Cash FlowsCash flows used
in financing activities for the three months ended March 31, 2009 were $0.3
million related to distributions paid.

Cash
flows provided by financing activities for the three months ended March 31,
2008 were $0.6 million related to $1.0 million of subscriptions received from
shareholders offset by $0.4 million of syndication costs paid.

Estimated Capital Expenditures

The
Fund has entered into multiple agreements for the drilling and development of
its investment properties. The estimated capital expenditures associated with
these agreements can vary depending on the stage of development on a
property-by-property basis. As of March 31, 2009, the Fund had committed to
spend an additional $18.3 million related to its investment properties.

When
the Manager makes a decision to participate in a particular project, it assumes
that the well will be successful and allocates enough capital to budget for the
completion of that well and the additional development wells and infrastructure
anticipated. If an exploratory well is deemed a dry hole or if it is
un-economical, the capital allocated to the completion of that well and to the
development of additional wells is then reallocated to a new project or used to
make additional investments.

Capital
expenditures for investment properties are funded with the capital raised by
the Fund in its private placement offering, which is more than likely, all the
capital it will be able to obtain. The number of projects in which the Fund can
invest will naturally be limited, and each unsuccessful project the Fund
experiences will reduce its ability to generate revenue and exhaust its
capital. Typically, the Manager seeks an investment portfolio that combines
high and low risk exploratory projects.

Liquidity Needs

The
Funds primary short-term liquidity needs are to fund its operations, inclusive
of management fees, and capital expenditures for its investment properties.
Operations are funded utilizing operating income, existing cash on-hand,
short-term investments and income earned therefrom.

The
Manager is entitled to receive an annual management fee from the Fund
regardless of the Funds profitability in that year. Generally, all or a
portion of the management fee is paid from operating income and interest
income, although the management fee can be paid out of capital contributions;
however, this is not the Funds intent.

Distributions
are funded from cash flow from operations, and the frequency and amount are
within the Managers discretion subject to available cash from operations,
reserve requirements and the Funds operations.

Off-Balance Sheet Arrangements

The
Fund had no off-balance sheet arrangements as of March 31, 2009 and December
31, 2008 and does not anticipate the use of such arrangements in the future.

Contractual Obligations

The
Fund enters into operating agreements with operators. On behalf of the Fund, an
operator enters into various contractual commitments pertaining to exploration,
development and production activities. The Fund does not negotiate any such
contracts. No contractual obligations exist at March 31, 2009 and December 31,
2008 other than those discussed in Estimated Capital Expenditures above.
