Abstract
Технология многостадийного гидроразрыва пласта в горизонтальных скважинах: опыт разработки коллекторов Shaly Carbonates в США и возможность адаптации для месторождений Республики Татарстан
Highlights
For a long time it was believed that production of hydrocarbons in tight and shale reservoirs is economically unprofitable
All three types of multistage fracturing are effective at 20 stages; acid and combined multistage fracturing are characterized by the biggest net discounted income of 240-280 million rubles
The purpose of this paper is to show how to efficiently develop oil source Domanic reservoirs in Tatarstan using multistage fracturing technology in horizontal wells, based on the analysis of developing Shaly Carbonates in the United States, which are the closest in terms of geological and physical characteristics
Summary
For a long time it was believed that production of hydrocarbons in tight and shale reservoirs is economically unprofitable. If we calculate the oil production rate of one well in Shaly Carbonates for a length of 270 m and 4 stages of the multistage fracturing, we will get 2025 tons/day, which can be taken as potential production rate of well 2917G for Domanic deposits. To achieve this rate, it may be necessary to use large amounts of acid, as well as proppant, additional research and careful selection of working fluids. All three types of multistage fracturing are effective at 20 stages; acid and combined multistage fracturing are characterized by the biggest net discounted income of 240-280 million rubles
