Well drilling in more depth and their operation require significant investments and they are
related to a high risk. The complications during drilling and operation process to a certain degree are
related to uncertainty of the reservoirs that are met in a well section.
Published practical data and research results allow in the opinion of US researchers to select
three types of reservoirs: “good”, “bad” and “ugly” /1/.
Above types of reservoirs have been selected under following parameters: producing depth;
position of abnormal-high formation pressure (AHFP)
upper limit, actual temperature and normal
design temperature in the depth to top of reservoir; earth pressure gradient; economic index of drilling
and production (table 1).
