Abstract

Exploring unconventional reservoirs is known to be

technically and economically challenging from drilling

to reservoir evaluation and stimulation. In order to

develop unconventional reservoirs, oil companies have

to drill and stimulate high number of wells which makes

geomechanics studies crucial to provide necessary

insights for successful operations. Dadaş Silurian

shale, located in SE- Türkiye, are being explored as

unconventional reservoir by the TPAO for decades.

Numerous problems related to formations instability

and or pore pressure have been reported while drilling

these formations. Hydraulic fracturing completed in

some wells turned out to be also very challenging in

various intervals. Considering these different problems,

a geomechanics study is completed at different scales

in Dadaş field to help improving, in the short term,

hydraulic fracturing operations and provide solutions

for drilling optimization to limit drilling-related nonproductive

time and bad hole conditions.
