PRIMARY OPERATING AREAS
Chesapeake's drilling activities are diversified over a number of different
geographical areas and geological formations in an effort to reduce risk.
Throughout these various prospect areas, the company utilizes such technologies
as horizontal drilling, deep vertical drilling, high-pressure fracture stimulation,
and enhanced 2-D and 3-D seismic to explore for and develop oil and natural
gas reserves.

AUSTIN CHALK TREND
GIDDINGS FIELD
Chesapeake's most significant assets are located in the Giddings Field, one of the
most active oil and natural gas fields in the U.S. Approximately 64% of the
company's estimated proved reserves at June 30, 1995 were located in Giddings.
The primary producing zone in the Giddings Field is the Austin Chalk
formation, a fractured carbonate reservoir found at depths ranging from 7,000
feet to 16,000 feet along a 10,000 square mile trend in southeastern Texas and
central Louisiana.
Chesapeake has concentrated its drilling efforts in the gas-prone downdip
portion of the Giddings Field, where the Austin Chalk is deposited at depths
below 11,000 feet. The company's downdip leasehold acreage is located in
Brazos, Fayette, Grimes and Washington Counties, Texas. Chesapeake's
engineers believe the downdip Giddings area is one of the largest discoveries of
onshore gas in the United States in recent years.
The Austin Chalk is a tight geological formation which holds large volumes
of oil and natural gas within its complex system of vertical fractures. Chesapeake
has developed a significant technological niche in the downdip portion of the
Giddings Field which has helped unlock the previously undeveloped reserves in
