Exhibit 99.1

WESTERN GAS RESOURCES, INC.
REDEEMS SENIOR SUBORDINATED NOTES

DENVER, June 24, 2004. Western Gas Resources, Inc. (“Western”) (NYSE:WGR) announced today that the Company completed the redemption of all of its outstanding $155 million aggregate principal amount of 10 percent Senior Subordinated Notes due 2009 at a redemption price of 105 percent of the principal amount plus accrued and unpaid interest through the redemption date.  The redemption was initially funded with amounts from the Company’s revolving credit facility.

In conjunction with the redemption, the Company will pay a prepayment fee of $7.75 million and realize a non-cash charge of approximately $2.5 million for offering commissions and expenses that were previously capitalized and were being amortized over the original 10-year term of the notes.  The Company will recognize an after-tax charge of approximately $6.5 million or approximately $0.09 per share of common stock (on a post-split basis) in the second quarter of 2004.  Based on the current interest rates, the Company expects to reduce interest expense by approximately $8.5 million annually as a result of this refinancing.

Peter Dea, President and Chief Executive Officer stated, “The redemption of our senior subordinated notes is another major step toward our efforts to simplify our capital structure and reduce fixed charges as we continue to develop our long-term inventory of unconventional natural gas resources under lease.”
