The Effect of Technological Fluids on the Productivity of the Jaran Deposits (D₃jar) of the Lyzhsko-Kyrtael’skii Uplift

The authors’ results show studies of the interaction of process fluids with rocks of the Jaran horizon (D₃jar), drilled within the Lyzhsko-Kyrtaelsky uplift, Timan–Pechora petroleum basin. The composition of the reservoir rocks of the studied deposits is represented by oligomictic feldspathic-quartz sandstones with carbonateclayey and clayey-carbonate cement. The study is devoted to assessing the influence of the killing fluid on the reseruoir properties of the reservoir rock using methods for measuring open porosity and absolute gas permeability using the Coretest System AP-608, the liquid saturation method according to Preobrazhensky, and filtration modeling using the installation PUMA-650.
