B-Series Safety Valve Landing Nipples
Hydraulic safety valve landing nipples
Contain pressure as part of a standard or heavyweight tubing string.
WRDP-1 slickline-retrievable subsurface safety valves are designed for sweet to moderately corrosive environments and feature rod-piston operation with flapper valves and an internal equalizing system that can be disabled by plugging the equalization ports before installation.
These valves are normally supplied with a fit-for-purpose lock for convenient use as a primary valve in applications where a value-engineered slickline valve is desired.
The WRDP-1 is operated by a rod-piston, premium sealing system. The primary flapper mechanism also has full metal-to-metal sealing and a secondary soft seat.
Some models of this valve are designed to be spring-spacer adjustable (SSA). SSA valves permit closing pressures to be varied during valve assembly by substituting spacers of different lengths instead of changing the power spring.
This initial appraisal of the latest-generation rigless wireline-deployed ESP replacement system indicates that it has the potential to drastically lower ESP operating costs by reducing production deferment, minimizing HSE exposure, diverting rigs to other operations, and positively impacting asset value.
