... failure (MTBF), the recovery factor of the reservoir and the increase of the economic limit. These goals can be achieved by applying a novel Finite Elements Method (FEM) for modeling and analyzing the behavior of the sucker rod string and the installed completion. These results are the basis...

..., Ecopetrol. Most of the failures in these wells are related to the contact between rod string and production tubing in high DogLegs points, up to 7.8°/100 ft, which causes two different failure mechanisms. One is the breaking of the rod string due to high contact loads, and the other is the wear on the inner...

...-effective way seek by the operators to minimize risks, maximize production, and remain profitable on the market. In wells with sucker rod-lift systems, elastic beam vibrations induced by downhole pump operation are the main source for premature rod string failure and tubing wear. A completely new steady...

... much lower as the tubing does not have to be pulled to repair the pump/rod string. Maximizing effective stroke length (i.e. net downhole plunger travel) and minimizing unswept pump volume and plunger area are critical elements in achieving higher pump efficiency and maximizing production potential...

... that most of the existing slippage models underpredict the slippage rate by a significant fraction. Therefore, it is necessary to do additional and more detailed tests to be able to define a more precise model to predict slippage losses during pumping operations. slippage sucker rod pump rod string...

... of tubing and plunger assembly at bottom of rod string. However, in an insertable sucker rod pump (ISRP), the entire pump assembly is run-in at the bottom of rod string and is landed on pump seating nipple (PSN) which was originally installed in the tubing string. Hence, installing SRP would require...
