All Multiphase Energy Corporation’s products and services are subject to the terms and conditions of any applicable contracts, available on request. Conventional artificial lift devices, such as a downhole pump or a plunger, are designed to be placed in a vertical oil or gas well. Placing the downhole pump in a deviated section of a horizontal well to reduce the back pressure on the reservoir or the amount of free gas that enters the pump results in high operating costs due to pump failures. In wells with plunger lift systems, the deviation can affect adversely plunger performance and create problems with plunger recovery. Increase estimated ultimate recovery (EUR) and reduce the operating costs using the MAPS-AL multiphase advanced pumping system for artificial lift, a unique technology solution for horizontal wells. How does MAPS-AL work? ▪ A pressure tank filled with a working fluid (water), a standing valve installed below the downhole pump, and free gas in the horizontal section of the horizontal well are used to displace a batch (predetermined volume or controlled slug) of liquids (oil and water) located between the downhole pump and the horizontal section (the heel section) into the annular space. ▪ Gas is discharged from the annular space into the pressure tank and an amount of free gas enters into the heel section from the horizontal section of the well such that the total flow rate in the heel section is increased during a time period. ▪ Then, the working fluid displaces gas from the pressure vessel back into the annular space and the standing valve closes, keeping the liquids at the downhole pump intake. ▪ The downhole pump transfers the liquids from the annular space into the tubing. ▪ The amount of free gas entered into the heel section is released into the annular space through the standing valve, once pressure in the heel section becomes sufficiently high, which allows free gas to rise up through the annular space towards the surface. ▪ The operation is performed repeatedly. MAPS-AL™ Multiphase advanced pumping system for artificial lift Applications ▪ Rod-pump systems ▪ Plunger-lift systems Advantages ▪ Permits operators to recover the liquids located below the downhole equipment installed in the vertical section of the horizontal well ▪ Increases production and reserves by gradually lowering flowing bottomhole pressure to avoid a quick rise of gas-oil ratio (GOR) ▪ Suppresses severe slugging ▪ Eliminates solids accumulation at the intake and inside the pump ▪ Extends the life of marginal horizontal wells ▪ Obviates the need for a source of pressurized gas ▪ Uses conventional equipment already proven in the field ▪ Logistical simplicity-easy to transport from one well to another and install ▪ Longer flowlines can be used to transport produced fluids to processing facilities without gas compression in the field Benefits ▪ Improved well deliverability ▪ Reduced workovers ▪ Increased estimated ultimate recovery ▪ Reduced flaring and venting of gas A patent-pending, innovative solution based on a new physical principle developed for pumping horizontal wells
- 2. www.mpecorp.com Solve key challenges of pumping horizontal wells Sucker-rod pumping brings a number of challenges when applied to horizontal wells: ▪ A high hydrostatic pressure of liquids accumulated in the heel section ▪ Multiple workovers replacing or repairing pumps due to excessive gas interference and solids deposited in the lateral ▪ Poor pump efficiencies ▪ A quick rise of gas-oil ratio (GOR) when the reservoir pressure drops below the bubble point of the oil MAPS-AL transmits energy to the liquids located below the downhole equipment using a centrifugal pump at the surface to solve all of the above challenges. The system delivers liquid batches to the intake of the downhole pump to increase the pump fillage and prevents the formation of the stationary bed of solids in the production liner and heel section. The latter feature is essential to avoid impaired productivity of perforation clusters within fracture stages and excessive solids concentrations in the fluids entering the downhole pump. MAPS-AL is engineered to lower gradually the flowing bottomohole pressure to maximize oil production and minimize the rate of increase of GOR. Reduce Lifting Cost According to a survey conducted in the Permian Basin, the failure frequencies are as follows: total is 0.66 per well per year, pump is 0.25 per well per year, rod is 0.22 per well per year, and tubing is 0.16 per well per year. The failure rate was about 2.5 well per year while pumping from the horizontal wells according to another study. Since MAPS-AL enables oil producers to operate the rod pump in the vertical section and solve above challenges, on average, the potential savings in workover costs can be $100,000 per well per year at $50,000/workover.
