Research on well selection and layer selection methods for tapping the remaining oil at the top of thick oil layers using ultra-short radius lateral drilling horizontal wells

The flexible drilling method of ultra-short radius sidetrack horizontal wells is an effective to utilize the remaining oil at top thick reservoirs. By analyzing current status SZ oilfield well network, development stage and sand body characteristics, combined with characteristics lateral technology, areas formations suitable for tapping are identified, criteria selecting established, which a guide application this technology.
