A circulating system of the drilling installation is designated for preparation, storage and pumping of drilling fluid into the well. It includes ground-based devices and installations ensuring rinsing of the well by multiple forced circulation of the drilling fluid in the closed loop along with carrying out a multistep cleaning off drilled solids and drilling fluid treatment with chemicals.
Development of an oil or a gas field is a set of activities aimed to ensure the oil and gas influx from the reservoir towards the well bottom, to set the sequence of the wells drilling and putting into operation, to fix and keep a certain mode of the wells operation.
Cementing of oil and gas wells is a final stage of their preparation for operation, which serves, first of all, to ensure maximum durability of the entire structure. Cementing ensures drilling fluid removal from the well, reinforcement of the walls of the well, securing casing strings and insulation of oil- gas- and water-bearing strata.
Hydraulic fracturing is one of the most effective methods to improve performance of oil and gas wells.
