                      DLB TO MERGE MID-CONTINENT/BARBADOS
                   ASSETS INTO CHESAPEAKE ENERGY CORPORATION,
                          AND SPIN-OFF BAYARD AND WRT

OKLAHOMA CITY, OKLAHOMA - October 22, 1997 - DLB Oil & Gas, Inc. (NASDAQ-DLBI)
today announced that it has entered into a definitive merger agreement with
Chesapeake Energy Corporation pursuant to which DLB shareholders will realize
the value of their DLB shares in the form of three separate securities.

Consideration will consist of $65 million of Chesapeake common stock and the
assumption of approximately $85 million in debt and other liabilities for DLB's
Mid-Continent and Barbados oil and gas assets. As of June 30, 1997, proved
reserves attributable to these properties were estimated by the Company to be
approximately 27 million barrels of oil equivalent. In addition, as part of the
transaction, DLB shareholders will receive their proportionate share of the
common stock of Bayard Drilling Technologies, Inc. (Bayard) and WRT Energy,
Inc. (WRT) owned by DLB. DLB currently owns 2,955,000 shares of Bayard and
10,354,198 shares of WRT, all of which will be distributed to DLB shareholders.

Charles Davidson, DLB's Chairman, said, "This merger will allow DLB
shareholders to enjoy the benefits of direct ownership of the three distinct
assets currently in our portfolio. First, each of us as shareholders will own
equity in Bayard Drilling, which is one of the largest land contract drilling
companies in the United States. Second, we will achieve significant operational
synergies by combining our Mid-Continent assets and our team with Chesapeake.
Third, by virtue of our WRT position, we will also own interests in a focused
South Louisiana exploration and production company with excellent core assets
in one of the most exciting areas in the country. We believe this realignment
of our three core businesses will ultimately maximize the value inherent in
each unique segment."

Mark Liddell, DLB's President, stated "Strategically, we believe this
transaction creates the best way to participate in the rapid consolidation we
see occurring in both oil field services and exploration and production. Our
fellow shareholders will experience higher liquidity, diversification, and
increased exposure to the positive effects of the consolidation process."

Under the terms of the merger, a subsidiary of Chesapeake will merge with and
into DLB. In the merger, shares of DLB common stock will be converted into the
right to receive: (1) a fractional interest in a share of Chesapeake common
stock equal to $65 million divided by the average of the closing prices of
Chesapeake stock for each of the first 20 consecutive trading days in the
period commencing 25 trading days prior to the date of DLB's special
stockholders meeting with respect to the merger, divided by the number of
shares outstanding on the closing date, (2) a number of shares of Bayard common
stock equal to 2,955,000 divided by the number of DLB shares outstanding on the
closing date, and (3) a number of shares of WRT common stock equal to
10,354,198 divided by the number of DLB shares outstanding on the closing date.
In the event that the average closing price for Chesapeake common stock used in
this calculation is less than $7.50 per share, each of DLB and Chesapeake shall
have the right, but not the obligation, to terminate the merger agreement.
Chesapeake will have the option to pay $65 million in cash rather than in
shares of Chesapeake common stock.

The merger is subject to approval of the holders of at least a majority of the
outstanding shares of DLB common stock as of the record date for the DLB
special shareholders meeting. The company anticipates a mid-January date for
the special meeting of shareholders. DLB currently has 12,975,000 shares
outstanding. Option acceleration under existing incentive plans may affect the
shares outstanding at closing. Charles Davidson, Mark Liddell and Mike Liddell,
who collectively own over 75% of DLB's outstanding common stock, have entered
into an agreement with Chesapeake pursuant to which, among other things, they
have agreed to vote in favor of the merger at the DLB special meeting.

The distributions of the WRT and Bayard shares will be subject to the
effectiveness of registration statements for such shares under the Securities
Act of 1933. In addition, the shares of Bayard, assuming a successful initial
public offering, will not be distributed until the expiration of 180 days from
the date of the pricing of Bayard's IPO. Pending distribution of the WRT and
Bayard shares, the shares will be held in escrow by the exchange agent for the
merger.

Lehman Brothers acted as DLB's financial advisor in connection with the merger
and DLB's review of strategic alternatives.
