Thesis. 
 
Formation evaluation is very important for drilling of exploration and development wells in the Caspian region. 
From the safety point of view, Real-Time formation evaluation helps prevent drilling associated risks, hazards and helps 
optimize drilling parameters in order to drill wells effectively and safely. For instance, pore-pressure prediction while 
drilling and wellbore stability estimation is based on Real-Time data, including sonic, gamma rays, formation pressure 
measurements and tests, as well as SDL and drilling parameters. By Real-Time monitoring and interpretation of the 
reservoir property measurements, formation-evaluation specialists can help to drillers and geologists in order to stay 
within the safety window limits, while drilling hard and soft formations and optimizing the revolution per minute, weight 
on bit, rate of penetration and other drilling parameters as was done successfully and safely in many wells drilled in the 
Caspian region. In current applications, Real-Time borehole geometry caliper measurements can help recognize and 
evaluate potentially unstable zones, where breakout and washout can take place in unstable zones. From well positioning 
point of view, Real-Time data can helps the geologists, geophysicist to evaluate and recognize the layer/strata, then 
perform geosteering, which can increase wellbore contact area in the reservoir zone, place the well precisely and 
accurately in the structure which is highly saturated with hydrocarbons, so advantage of formation evaluation in this case 
can be increase of hydrocarbon production rate and enhance the reservoir understanding.
