A frequency-elastic drive mode for a sucker rod pumping system is introduced to reduce its
polished rod peak loads and the total energy consumption. Numerical modeling and an …

Low oil prices push the demand for efficient oil and gas production, especially in mature
fields. Reducing the costs of artificial lift systems by increasing efficiency is mandatory for …

This paper presents a thorough overview of hydraulic stimulation techniques, conducted in
laboratories. It further analyses field experiments and ongoing projects for geothermal …

An advanced dynamic finite element model is presented that diagnoses the downhole pump
performance of sucker rod pumping systems, applicable for any pumping conditions and …

Artificial lift systems (ALS) are used in mature oil fields, which have insufficient pressure to
produce hydrocarbons naturally. Nowadays, sucker rod pumping systems hold a significant …

Sucker rod pumping is the most widely used artificial lift method in oil and gas wells. The
surface component of this unit is the pump jack which is designated to impart the …

This article aims to introduce a novel environmentally friendly hydraulic stimulation fluid,
which follows all the latest regulations and can be accepted by local governments and …

Sucker rod pumping is the most common type of artificial lift systems deployed in oil and gas
wells. The sucker rod string, transferring the reciprocating movement of the surface polished …

Economic situations and governmental restrictions push the demand for efficient oil and gas
production, especially in mature fields. The reduction of artificial lifting costs by increasing …

The large amount of energy losses along the system of a sucker rod pump is one of the key
disadvantages of this artificial lift method, which dictates the energy consumption and drives …
