Improving the operational conditions for the sucker-rod pumping system

A New Methodology to Analyze Fluid Pound in Sucker-Rod Pump Systems: Phenomenological Approach

“…Through these charts it is possible to identify if the well is producing correctly or if there is an operational or failure problem. One of the major problems in this type of analysis is that it cannot be extended to other wells since the chart is obtained from field data ( [4], [8], [9], [10]). In this way, a methodology that predicts the behavior of the pump in function of the operational data would be of great utility.…”

Model Reference Adaptive Control Applied to the Improvement of the Operational Conditions of a Sucker Rod Pump System

“…However, if the chamber was not completely filled, the plunger finds a gas column, in B, whose low pressure is not enough for opens the traveling valve. The advance of the plunger, at some moment, will suddenly find the fluid column in the plunger interior, in C, what it goes to cause a strong transference of the load, and therefore, a strong mechanical impact on the pump components (Ordoñez et al, 2008).…”

“…The systems that are used sucker rod pumps, most of time is desired that the operation point is next to the pump suction level. This operation point is characterized by the complete pump filling with the minor WF P possible, which provides a minor against pressure in the production zone of the reservoir, and, in turn, increases the oil production (Ordoñez et al, 2008).…”

Scheduling pumpoff operations in onshore oilfields under electric-power constraints

“…In onshore fields, sucker-rod pumping is a widely applied technique for its relative low investment and maintenance cost, inherit flexibility, and variable production rate (Lake, 2007;Ordoñez, 2008;Ordoñez et al, 2009). A rod-pump system consists of a rotary machine connected to a plunger that runs inside the production tubing.…”
