Gas demand in the years of our country, consistently shows an increasing trend, hence there
is an urgent need for new storage fields. Yulaflı Field is studied as thought to be a part of the
Thrace Region Underground Gas Storage Project. This study has been conducted in order to
calculate volume of gas in place by 3D geological modelling of Yulaflı Field and to provide a basis
to underground gas storage simulation studies with an integrated reservoir characterization
study, taking into account the sequence stratigraphy studies previously done, including seismic
interpretations, structural properties, well log data, well correlations and production data. In
the fields, which have limited number of wells such as Yulaflı, a geological model has not been
sufficient to demonstrate the character of the reservoir by using only well data, thus, a secondary
data set has to be used. In this study, the interpretated well log data and seismic data have been
properly integrated and used in a combination. Thus, a more accurate and detailed 3D geological
model was created representing the reservoir characterization of the field.
