Delta Petroleum Purchases Castle Energy Corporation Oil and Gas

  Company Also Completes Tipperary Exchange and Other Strategic Transactions  
  DENVER, June 3 /PRNewswire-FirstCall/ -- Delta Petroleum Corporation 
(Nasdaq: DPTR; Frankfurt: DPE), an independent energy exploration and 
development company, today announced that the Company has closed on a number 
of strategic transactions during the past week, including purchase of the 
domestic oil and gas properties of Castle Energy Corporation.  In addition, 
the previously announced property exchange with Tipperary Corporation 
(Amex: TPY) has been completed, the Company has closed on a new Credit 
Agreement with the Bank of Oklahoma and Local Oklahoma Bank, and an office 
building in Ft. Worth, Texas has been sold.  
Shareholders approved the Company's purchase of the domestic oil and gas 
properties of Castle Energy Corporation at Delta Petroleum's annual meeting on 
May 30, 2002, and the transaction was completed on May 31, 2002.  The 
properties acquired from Castle consist of interests in approximately 
525 producing wells located in fourteen (14) states, plus associated 
undeveloped acreage, with proved reserves of approximately 62 billion cubic 
feet of gas equivalent (Bcfe), of which proved developed producing reserves 
total approximately 32 Bcfe.  The Company issued 9,566,000 new shares of 
Common Stock to Castle Energy Corporation as part of the purchase price.  "The 
Castle acquisition more than doubles Delta's daily production to approximately 
22 million cubic feet of gas equivalent per day comprised of approximately 
45% oil and 55% natural gas," noted Roger Parker, President and 
Chief Executive Officer of Delta Petroleum Corporation.  
"At current commodity prices and current daily production rates, Delta's 
oil and gas revenue could be in excess of $27 million for the fiscal year 
ending June 30, 2003, and cash flow from operations could exceed $13 million. 
Following the acquisition, our proved natural gas equivalent reserves 
approximate 80 billion cubic feet, compared with 18 billion cubic feet prior 
to the Castle purchase.  We expect to immediately initiate workover, 
recompletion and drilling activities on certain of the Castle properties in 
order to further increase daily production," continued Parker.  
The Company has also completed the sale of its undivided interests in an 
Authority to Prospect (ATP) covering lands in Queensland, Australia, to 
Tipperary Corporation, in exchange for Tipperary's producing properties in the 
West Buna Field (Hardin and Jasper counties, Texas), $0.7 Million in cash, and 
250,000 unregistered shares of Tipperary common stock.  The West Buna Field 
properties contain proved natural gas equivalent reserves totaling 
approximately 4.3 billion cubic feet (Bcf).  Net daily production from the 
West Buna Field approximates 900,000 cubic feet equivalent.  
Also during the past week, Delta Petroleum closed on a new $20 million 
Credit Agreement with the Bank of Oklahoma and Local Oklahoma Bank. 
Approximately $19 million of the credit facility was utilized to close the 
Castle Energy transaction and to pay off Delta's existing loan with US Bank. 
The Company's total debt now approximates $25 million.  "The new revolving 
credit facility and net cash increases from the recent transactions will 
provide substantial working capital from which we can conduct more meaningful 
development activities on our existing property base," stated Parker.  
Delta Petroleum generated $417,000 in cash through the sale of its 
Ft. Worth, Texas commercial office building.  "The sale of the building was 
consistent with our strategy of divesting assets that are not necessary for 
achievement of our strategic goals as a domestic exploration and development 
company," concluded Parker.  
  Delta Petroleum Corporation is an oil and gas exploration and development 
company based in Denver, Colorado.  The Company has producing properties in 
numerous states and interests in one producing federal unit and four 
undeveloped units located in federal waters offshore California near 
Santa Barbara.  Its common stock is listed on NASDAQ under the symbol "DPTR"
