Although sand flow is greatly reduced following an initial period of flow (30 to 60 days), the slugging nature of horizontal wells provides a significant risk for unexpected large quantities of sand to damage permanent separation equipment, surface piping and valves. Installing sand probes has...

... string is directly related to difference in pressure across the plunger over the plunger area. Typical pump card loads plot near zero load when the traveling valve, TV, is open during the down stroke. When the standing valve, SV, is open during the upstroke the pump card loads should plot near fluid load...

... into the pump, the gas would generally be separated at bottom hole, then enter the annulus between the tubing and the casing (tubing-casing annulus), eventually flow in air or enter oil pipeline by many control valves at wellhead. In this system, the gas is a potential damage factor to the pump. So the pump...
