Annotation:
The Senonian-Turonian gas-bearing complex in the fields with depleted gas reserves in Cenomanian deposits can be developed either as an independent facility or a return facility for transferring Cenomanian wells to the Senonian-Turonian horizon. To develop the Senonian-Turonian gas deposits, it is planned to build single-hole wells with rising and flat ends, where ports for hydraulic fracturing (HF) are installed. The Senonian-Turonian deposits are porous-fractured reservoirs composed of clayey rocks with interlayers and lenses of sandy-siltstone material. The secondary opening of such reservoirs is carried out by cumulative perforators with high penetrating power. For de-colmatation of the near wellbore area, it is recommended to carry out clay-acid treatments of the near wellbore area or hydraulic fracturing.
