($ in millions, except EPS data)

Overriding Goal is to Maximize Total Shareholder Return

• We believe this can be achieved through a combination of:

• Growing our oil and gas production by 5% to 8% per year on
average over the long term;

• Allocating and deploying capital with a focus on achieving
well above cost-of-capital returns (ROE and ROCE);

– Return Targets*

• Domestic - 15+%

• International - 20+%

• Consistent dividend growth, that is superior to that of our
peers.

*Assumes Moderate Product Prices

Cash Flow Priorities

• Our ability to pay dividends is indicated by our free cash
flow generation.

• In February 2012 the Board of Directors increased the
company’s dividend by 17% to an annualized rate of $2.16
per share, compared to the previous annual rate of $1.84.

• We have now increased our dividend every year for 10
consecutive years, and a total of 11 times during that
period.

• This increase brings the company’s compound annual
dividend growth rate over the last 10 years to 15.8%.

• We expect to increase our dividends again this year and
in the future at a rate that would maximize returns to our
stockholders.

Large Cap Independent E&P

S/Mid Cap Oil Focused E&P

• These expenditures include
capital for:

– the Al Hosn Shah gas project
which is expected to start
production in late 2014;

– gas and CO2 processing
plants and pipelines to
maintain or expand the
capacity of these facilities to
handle future production
increases;

– the chemical segment, and
other items.

Capital Spending

• In 2012, we expected to spend
~25% of our total capital
expenditures on future growth
projects that will contribute to
our operations over the next
several years.

S/Mid Cap Oil Focused E&P

• Over the past year, we have achieved our goal of
increasing domestic production by 6 to 8 mboe/d
quarter-over-quarter.

– We expect our 4Q12 oil production to grow by about this much.

– However, the expected decline in gas production resulting from
the change in our capital program focus may offset some of the
increased oil production on an equivalent basis.

• Internationally, at current prices we expect production
to be approximately flat with 3Q12, while sales volumes
increase slightly.

4Q12 Outlook - Oil and Gas Production

• Base 5 - 8% Compounded Average Annual Growth

– Current California risked prospects

– Non-CO2 & CO2 in the Permian

– Oman

• Upside from Existing Holdings

– New California conventional and unconventional prospects

– Permian exploration

– Williston Basin & Rockies

– Oman exploration

– Bahrain and Iraq

• Additional opportunities from balance sheet and cash
generation

– Domestic property acquisitions

– New Middle East projects

Oxy Acreage

• Largest acreage holder in CA
with ~1.7 mm acres, majority of
which are net mineral interests

• 3Q12 production of 147 mboe/d

• Diverse geologic
characteristics and numerous
reservoir targets

• Development opportunities
range from conventional to
steam floods, water floods and
shales

• Drilling costs and expected
ultimate recoveries (EURs) vary
for each opportunity

• 78% interest in the Elk Hills
Field — the largest producer of
gas and NGLs in CA

California Conventional Exploration

• World Class Province

– 35+ Billion BOE discovered

– 5 of top 12 U.S. oil fields

• Significant Remaining Potential

– Large undiscovered resources

– Multiple play and trap types

• Underexplored

• Oxy

– Major producer

– Largest acreage holder

– Successful explorer

– Multi-year prospect inventory

• Multi-year inventory of drill sites in
CA, many of which are both outside
of Elk Hills proper & the Kern County
Discovery Area

• 30-day initial production rate for
these wells is between 300 and 400
BOE per day

• For the shale wells outside Elk Hills,
~80% of the BOE production is a
combination of black oil and high-
value condensate

• We expect the cost of drilling and
completing unconventional wells to
decline significantly over the medium
-term

California Unconventional “Shale” Program

• Total CA production growth on a BOE basis is slower than we
thought it would be, in part due to the Elk Hills decline, permitting
issues and more recently low gas prices.

• On a positive note, overall performance of the new resources has
been consistent with expectations, including our unconventional
opportunities for which well performance is similar to the type curves
we disclosed a couple of years ago.

• We will continue our focus on higher return, low cost opportunities in
CA, and this is a very diverse opportunity set.

• For example, Lost Hills - a major steam flood project

– We expect to achieve significant production growth to about 15 mb/d in several
years from the current 4 mb/d;

– Total oil in place in Lost Hills is estimated to be about 500 million barrels;

– Using reasonable assumptions, we expect to recover over 50 million barrels
net to Oxy;

– Our drilling costs in this area average in the low $200,000's per well
and we expect to bring this average cost down over time.

California Update

• In mid-2010, we shifted our development program to conventional and
unconventional opportunities outside of the traditional and more mature
Elk Hills areas.

• Over the last several years we
have spent $370 mm on the
new Elk Hills gas plant.

• The plant went into operation in
early July and, notwithstanding
initial startup issues, is
positively affecting our
operational efficiency and
production including higher
liquids yields.

• The plant operated optimally
for about one month in 3Q12
and has been operating as
expected since.

Permian Basin Overview

• 3Q12 production of 209 mboe/d

• Largest oil producer in Permian
(~15% net share of total)

• Largest operator in Permian
(of 1,500+ operators)

• ~64% of Oxy’s Permian oil
production is from CO2 related
EOR projects - Oxy’s most
profitable business

• Drilled ~409 wells on operated
properties in 2011

• Have another 2.5 BBOE of likely
recoverable resource

• 1.7 bcf/d (0.5 tcf/year) of CO2

• Ample supply of CO2 accelerates
project implementations

Acreage in Select Permian Plays

(Thousands of Acres)

• Permian non-CO2 business is one
of Oxy’s fastest growing assets;

• Since beginning delineation and
development efforts in 2010, we
have grown production by +25%;

• As a result of the significant
activity by us and our partners,
our Permian acreage where we
believe resource development is
likely, has grown from our
estimate of about 3 mm gross
acres earlier in the year to about
4.8 mm acres in October;

• Oxy's net share of this acreage
grew from about 1 mm acres to
about 1.7 mm acres during the
same period.

• Oxy holds a 40% participating
interest under a 30-year contract;

• The project involves development
of high-sulfur content reservoirs
within the Shah field, located
onshore ~180 km so. west of Abu
Dhabi;

• Production start-up is scheduled
in late 2014;

• Anticipated to produce ~500
mmcf/d of sales gas and 50 mboe/d
of NGLs and condensate -
providing net to Oxy ~200 mmcf/d
of gas and ~20 mboed of NGLs and
condensate.

Oxy Oman Gross Production Growth

– Working capital reduced our nine-month cash flow from operations of $9.2 billion by ~$660 mm to $8.5 billion.
~$510 mm of working capital use occurred in 3Q12. Capex was $7.7 billion for the first nine months, of which
$2.6 billion was spent in 3Q12; YTD capex was 82% in oil and gas, 14% in midstream and remainder in chemicals.
Financial activities, which included dividends paid, stock buybacks and a $1.74 billion borrowing earlier this year,
provided a net $300 mm of cash flow.

• Company’s core business is acquiring assets that can provide
future growth through improved recovery.

– Foreign contracts

– Domestic add-ons

– Small incremental additions to production in short term

• Generate returns of at least 15% in the US and 20% overseas.

• Overall average finding & development costs of less than 25%
of selling price.

• Our program continues to generate a significant amount of free
cash flow after capital.

• Acquisitions are measured against reinvesting in the existing
business with the goal of enhancing company value.

• Large number of opportunities over 5-year period.

• Deep inventory of high-return opportunities eliminates the need
to pursue capital intensive acquisitions.

Acquisition Strategy

• 5 - 8% base annual production growth over the long term

• Opportunity for additional volume growth

• Returns on invested capital significantly in excess of the
Company’s cost of capital

• Consistent, annual increases in dividends

• Significant financial flexibility for opportunities in distressed
periods

• Conservative financial statements

• Committed to generating stock market value which is greater
than earnings retained

• We believe this will generate top quartile returns for our
shareholders
