Abstract: The article discusses the opening of formations at abnormally high reservoir pressure (AHRP), the rules for the installation and operation of blowout equipment for the production column of an inclined directional production and evaluation well for the purpose of successful drilling of well No. 707 at the Western Cheleken field in the coastal zones of the coastal waters of the Caspian Sea. For the design of the opening of reservoirs at the AHRP, the rules for the installation and operation of blowout equipment were carried out according to the "Instructions for testing wells for tightness", "Safety rules in the oil and gas industry", as well as calculations for tightness were carried out in accordance with the "Instructions for calculating casing strings for oil and gas wells" (RD 39 - 7/1 - 0001 - 89, Vnitneft) and "Instructions for testing wells for tightness". This work on the design of the opening of reservoirs with AHRP, the rules of installation and operation of blowout equipment can be used in order to avoid complications, accidents, gas and oil occurrences and to perform tasks when drilling directional wells and in extremely difficult mining and geological conditions at abnormally high reservoir pressures.
