Standng Valve TestStanding Valve Load Test (above right) is a representative and correctlytaken standing valve test load. The load trace is located at the standing (SV)load line and is sometimes called Wrf. The rod string load is measured, not theload on the "standing valve". This test records the load on the sucker rod stringwhen it is immersed in wellfluid and the standing valve is not leaking. SV loadtrace will usually be a flat line showing no weight gain unless the standing valveis leaking, or there is leakage from the pump or tubing.

Traveling Valve TestTraveling Valve Load Test (above right) is a representative and correctlytaken traveling valve load test. This load trace is located at the traveling (TV)load line and is sometimes called Wrf + Fluid Load. The test records the loadon the rod string immersed in well fluid, plus the fluid load applied to the rodstring by the pump plunger. When the traveling valve is not leaking, the loadtrace will usually be a flat line showing very little weight loss of the fluid load.Normally, the TV load leaks between the pump plunger and barrel clearances.
