The vertical branches make vertical flow path which is similar to hydraulic fracturing. They are open hole liners that link the well with the reservoir and perform all fishbone operations. For instance, circulating the fluids with the rig pumps and setting the liner hanger slips become easy with the help of a fishbone stimulation system.
Fishbone wells are one of the most effective ways used to improve the production rate of wells. The design of the wells is a complex process as it focuses on the optimization of branch length, branch number, and branch angle.
The process is an effective method for economic development at low permeability, low yielding oil reservoirs, and low abundance. Some advantages of the wells include:
- They provide high well production rate.
- The engineering costs can be reduced.
- They reduce the economic risks in heterogeneity stratum.
