Exploring unconventional reservoirs is known to betechnically and economically challenging from drillingto reservoir evaluation and stimulation. In order todevelop unconventional reservoirs, oil companies haveto drill and stimulate high number of wells which makesgeomechanics studies crucial to provide necessaryinsights for successful operations. Dadaş Silurianshale, located in SE- Türkiye, are being explored asunconventional reservoir by the TPAO for decades.Numerous problems related to formations instabilityand or pore pressure have been reported while drillingthese formations. Hydraulic fracturing completed insome wells turned out to be also very challenging invarious intervals. Considering these different problems,a geomechanics study is completed at different scalesin Dadaş field to help improving, in the short term,hydraulic fracturing operations and provide solutionsfor drilling optimization to limit drilling-related nonproductivetime and bad hole conditions.
