..., Water, Gas), hydraulic fracturing design (frac sand size), and CWA (Complete Water Analysis). This paper proposes a new method to deal with sand and chemical problems in the ESPs. The solution includes three steps: Isolation method, sand control system, and down-hole chemical treatment. The isolation...

... controller control system low production well spm Introduction Statistics show that the number of well with less than 5 m 3 /d production account for more than half of the total wells in CNPC (Cai Wang et al., 2019 ). Most of the time, these wells have a low system efficiency due...

... There is significant OPEX costs associated with operation and maintenance of the hydraulic control systems. Periodic testing (typically every 6 months) must be performed by cycling the valves and for each cycling, hydraulic oil may need to be flushed through the system to maintain National...

... injector design was discounted and a non-standard sand management control technique developed using a cased & perforated (C&P) and downhole flow-control system (DHFC). During this program, BP ACG has successfully installed the world's first 10kpsi three-zone inline variable-choke DHFC wells...
