CREDO REPORTS FINANCIAL RESULTS FOR THE QUARTER ENDED JANUARY 31, 2012

Increased Oil Production Drives Significant Improvement in Financial Results

First Quarter Oil Production Increased 99% and Operating Income Increased 127%

DENVER, COLORADO, March 13, 2012 - Credo Petroleum Corporation (NASDAQ: CRED), an oil and gas exploration and production company with significant assets in the North Dakota Bakken and Three Forks, Kansas, Nebraska, the Texas Panhandle and Oklahoma, today reported financial results for its first fiscal quarter of 2012.

A 99% increase in oil production volumes drove significantly improved financial performance in the first quarter of 2012. The following table shows the changes in certain financial and operational categories for the quarter ended January 31, 2012 compared to the same quarter last year.

Revenue + 79%
Operating Income + 127%
EBITDA + 96%
Net Income + 515%
Adjusted Net Income + 88%
Total Production (BOE) + 36%
Oil Production (BO) + 99%

Operating income increased to $2,052,000 compared to $904,000 last year on revenue of $5,821,000 compared to $3,250,000 last year. Increased production volumes accounted for 94% of the revenue increase while price changes accounted for 6% of the increase.

EBITDA (a non-GAAP measure; see reconciliation below) for the first quarter of 2012 increased to $3,842,000 compared to $1,960,000 last year. Net income was $1,040,000, or $.10 per diluted share, compared to $169,000, or $.02 per diluted share, last year. Adjusted net income (a non-GAAP measure; see reconciliation below) increased to $1,367,000, or $.14 per share, compared to $726,000, or $.07 per share last year.

DRILLING SUCCESS DRIVES SURGE IN OIL PRODUCTION AND 36% INCREASE IN TOTAL PRODUCTON VOLUMES

The Company's oil-focused drilling success yielded a 99% increase in first quarter 2012 oil production compared to last year. Natural gas drilling was suspended in 2009 because of low natural gas prices. As a result, mostly normal declines reduced gas production by 9% in the first quarter compared to last year. The following table shows that the Company's comparative first quarter production mix shifted solidly in favor of oil.

First Quarter Production Mix 2012 2011
Crude Oil 61% 42%
Natural Gas 39% 58%

Total production volumes increased 36% in the first quarter to 91,000 BOE (barrels of oil equivalent based on six Mcf of gas to one barrel of oil) compared to last year. The following table shows comparative first quarter production volume percentages by region and highlights the robust shift occurring in the Company's production mix to crude oil in North Dakota, Kansas and Nebraska and away from natural gas in Oklahoma.

First Quarter Production by Region 2012 2011
North Dakota Bakken and Three Forks 21% 10%
Kansas and Nebraska Lansing Kansas City 21% 15%
Texas Panhandle Tonkawa and Cleveland 10% 8%
Other (primarily Oklahoma natural gas) 48% 67%

Michael D. Davis, interim Chief Executive Officer, stated, "Although we are required to report production volumes on their six to one energy equivalent basis, the current price equivalent is more than forty to one. That makes oil worth about seven times more than natural gas, which is magnifying our revenue growth and bottom line results compared to our production growth. For example, in the first quarter of 2012, oil represented 86% of the value of production compared to 61% of production volumes."

The following table shows comparative first quarter revenue percentages by region.

First Quarter Revenue by Region 2012 2011
North Dakota Bakken and Three Forks 27% 15%
Kansas and Nebraska Lansing Kansas City 32% 26%
Texas Panhandle Tonkawa and Cleveland 9% 5%
Other (primarily Oklahoma natural gas) 32% 54%

FIRST QUARTER WELLHEAD PRICES MIXED

First quarter wellhead oil prices increased 13% to $90.33 compared to $79.75 last year. Natural gas prices fell 14% to $3.73 compared to $4.34 last year. For the quarter ended January 31, 2012, the Company had realized hedging losses of $44,000 compared to gains of $36,000 last year. First quarter oil hedges had the effect of reducing the Company oil price realizations by $.79 per barrel to $89.54. Last year, natural gas hedges increased first quarter price realizations by $.16 per Mcf to $4.50.

At January 31, 2012, the Company held short swap hedge positions on 6,000 barrels of oil per month for the production months of February 2012 through December 2012, at prices ranging from $91.95 to $93.00. The hedge is expected to cover approximately 15% to 25% of estimated production for the hedged period. At first quarter end, unrealized hedging losses were $481,000 compared to $741,000 last year. The unrealized losses are a non-cash charge calculated at a point in time by applying oil prices as of first quarter-end to open hedging contract volumes. Actual realized gains or losses on the hedges are determined based on oil prices at the time each month's hedge contract expires.

RECORD CAPITAL EXPENDITURES
TO BE PARTIALLY FINANCED BY BANK BORROWING

Capital expenditures are expected to more than double in fiscal 2012 to $35,000,000, of which approximately 65% is earmarked for Bakken and Three Forks drilling. For the first time in Credo's history, financing will be required to fund a portion of the Company's capital expenditures. Accordingly, the Company has established a revolving credit line with its principal bank which provides for a $25,000,000 credit facility. The initial borrowing base is $7 million but will be increased as the Company pledges additional properties as collateral. Borrowing in 2012 is expected to range from $7 million to $12 million. The credit facility is governed by a borrowing base which is determined semi-annually by the lender based on review of the Company's reserves at April 30 and October 31. To date, the Company has drawn $2 million on the line of credit with an effective interest rate of 3.5%.

MANAGEMENT COMMENT

Davis continued, "We have been extremely successful transitioning Credo from natural gas to oil in a relatively short time frame. Our comparative first quarter oil production grew 99% and for the quarter, oil represented 61% of our production mix. We will continue to build on that momentum throughout 2012 with the objective of oil comprising 75% of our production mix by year-end.

"We entered 2012 with a balanced, multi-year inventory of projects that will propel Credo's organic production and reserve gains in the years ahead. In our Bakken and Three Forks project alone we have approximate 200 to 250 drilling locations based on two Bakken and two Three Forks wells in each spacing unit. That number could double if, as many of the larger Bakken operators predict, well density increases to eight wells per spacing unit."
