PNEUMATIC PUMPING SYSTEM BPZ
With proven efficiency in more than 50 wells, the BPZ system reduces the well’s flux pressure, thereby increasing the production rate in relation to the Gas Lift pumping method. The BPZ can eliminate rig maintenance interventions, very common, in mechanical pumping operations, since its structure lacks movable parts. In addition, BPZ can be used in directional wells, or wells that produce high quantities of gas, factors that make mechanical pumping implementation unfeasible.
CYCLIC STEAM INJECTION SYSTEM WITH ALTERNATE PRODUCTION
The Cyclic Steam Injection System with Alternate Production, known as ICVPA, enables steam injection alternating with oil production, without the need of a rig intervention. This system is a derivation of BPZ and, for this reason it presents all the advantages BPZ has in relation to others methods. The ICVPA was developed to artificial lift projects of heavy oil. Is associated with the advantages of gas lift and mechanical pumping systems, promoting a significant reduction in energy losses.
FLOW PRESSURE REDUCTION SYSTEM FOR PUMPED WELLS
The Flow Pressure Reduction System for Pumped Wells, known as SRP, has the objective to increase the production from pumped wells by reducing its flow pressure through the reduction of the pressure jacket. The SRP has a natural gas suction/compression system developed by ENGEPET, beyond all automation and instrumentation necessary for its operation. Some of the advantages of SRP are:
Rigs interventions are not required for installation or modification of the lift system existent, unless the change needed to adapt to a new flow rate;
In the case of Wells where the annular gas is vented to atmosphere, the SRP allows the recovered of the produced gas and the removal of environmental damage, without reduction of oil production;
It can be applied in Wells that have oil flow line equipped with Mechanical Pumping Systems, Progressive Cavity Pump or Submersible Electric Pump.
