PROGRESSING CAVITY PUMP SYSTEMS Two Run Insertable PC Pump NOV Monoflo has an innovative, new insertable progressing cavity pump design that allows the customer to insert a pc pump inside the production tubing and pressure test the tubing string with one easy to use tool. Features and Benefits • There is no need for a service rig to pull the production tubing to change a downhole pump • Pump changes can be done with a flushby equipped for rod handling • The unit minimizes the need to remove production tubing, reducing the cost of downhole gauge installations • Allows for pressure testing the production tubing as well as the primary seal, while inserting the stator. • The system has the ability to use any progressing cavity pump without performing any modifications. • The system can pull the rotor out of the well bore without unseating the primary seal. Mechanically Bonded Stator Well temperatures can increase due to natural conditions and the use of thermal stimulation techniques. These conditions challenge the viability of the traditional chemically bonded pc pump stator. One way to address this challenge is through new methods of anchoring the elastomers into the stator tube. NOV Monoflo has developed elastomeric stator technology to meet demands of high temperature wells. The mechanically bonded stator is comprised of 3 main components (not including the elastomer): • Stator Tube • Mechanical Bond Inserts • End Caps Available in two elastomer grades: • OBX suitable for temperatures up to 110° C • OC suitable for temperatures up to 150° C Available sizes: D32-900 (1 raw) D96-1040 (2 raw) D54-1800 (3 raw) D44-900 (1 raw) D150-300 (1 raw) D64-1560 (3 raw) D54-1200 (2 raw) D32-1800 (2 raw) D96-1560 (3 raw) D64-1040 (2 raw) D44-1800 (2 raw) D150-600 (2 raw) Rotor Operating Position Insert Tool Seating Nipple Insert Position Stator Tag-Bar Torque Anchor Seating Mandrel with Primary Seal
NO-GO Tag Progressing Cavity Pumps The NO-GO Tag system is a new advanced generation tool for rotor placement in progressing cavity pumps. It provides all the functionality of a traditional bottom tag bar system with the following advantages. Features and Benefits • Tags within the stator, leaving intake free of obstruction, allowing rotor to agitate solids • Coilable through the pump by only pulling up polish rod • Protects top end of stator elastomer by guiding coil entry through the pump • Positive tag for proper rotor placement by guiding rotor through timed helical tag passage into stator elastomer • Unique integrated design eliminates flow losses and extra connections • Tags using a conventional rod box • Ability to land pump lower in well • Eliminates costly mechanical tools below the pump while maintaining circulation clean-out capabilities Application • Medium to heavy oil • Wells producing solids (sand, coal fines, pyrite, etc.) • Wells with history of intake plugging • Wells with minimal cellar Charge Pumps Problem wells that produce slug sand, water, and/or gas can benefit from the use of a Charge Pump. These pumps have 3 main parts: • Production Pump - determines your lift capacity and final volume. • Pup Joint - usually located between the two pumps and has additional holes or slots depending on the application. • Charge Pump - higher volume, lower pressure pump that maintains consistent wellbore fluid by mixing it before entering the production pump.
