US Patent 9 938 804 B 2 A

US Patent 9, 938, 804 B 2 A superior method to optimize sucker rod pumped wells POC HYDRAULIC TECHNOLOGIES

A Pump Off Control (POC) skid mounted equipment package has been designed to provide oil & gas operators a more economical way to control sucker rod pumped wells using variable speed drive control without the need for expensive power in remote/non-electrified locations. Wells produce the maximum amount of fluid possible. Avoid fluid pound resulting in less wear on pump and rods. The equipment package is ideal for both new wells with fluctuating production or old wells where you have to match the speed with inflow. Whether you need to speed it up/slow it down this product is desirable for sucker rod pumped wells in areas where electrification is uneconomic. POC HYDRAULIC TECHNOLOGIES

Hydraulic variable speed drive (0 -8 spm) Counterbalance valve which eliminates over revving the engine when out of balance. Applicable to new and existing installations. Pump off controller for full automation capable of easily integrating with an existing SCADA system. Proven variable speed control for natural gas RICE engine driven systems. POC HYDRAULIC TECHNOLOGIES

ü ü ü ü Increased Production Produce the maximum amount of liquid available Provides the longest run time possible Fully automated pump-off control Lower Operating Costs Less packing changes, fewer spills & reduced stress on the rods Dramatically reduced number of well workovers Can switch direction of jack easily to maintain even wear on gears in the gearbox. Modbus 485 capabilities to connect directly to your SCADA system to monitor all wells thereby controlling operating costs Reduced Capital Costs No need to run power into sites for speed variance POC HYDRAULIC TECHNOLOGIES

High Frequency Workovers New Drills Wells with Erratic Inflow Gas locking Timer wells Packing leaks Hot rods Fluid pound Low production wells Deviated or Horizontal wells Wax issues Gas well dewatering Jackshaft replacement Tubing Rotator Wells Enviro Sensitive Areas Consistent high Fluid levels Reservoir stimulated wells POC HYDRAULIC TECHNOLOGIES

Flow control eliminates the need for a clutch. No need to run power to a site, or rent an expensive generator. Low maintenance costs. Soft start easier on equipment. Lower engine RPM translates to longer engine life. POC HYDRAULIC TECHNOLOGIES

ACCURATE ROD PUMPING SYSTEM CONTROL AND ANALYSIS WITH THE LUFKIN WELL MANAGER ROD PUMP CONTROLLER THE LUFKIN WELL MANAGER (LWM) ROD PUMP CONTROLLER’S PATENTED ALGORITHMS ACCURATELY CONTROL AND ANALYZE YOUR ROD PUMPING SYSTEM, MAKING IT A LEADER IN ROD PUMP CONTROL AND TOTAL WELL MANAGEMENT. ITS POWERFUL TECHNOLOGY CALCULATES A DOWNHOLE CARD ON EVERY STROKE OF THE PUMPING UNIT BY USING THE COMPLEX MATHEMATICAL COMPUTATIONS FOUND IN DIAG™ SOFTWARE. THE FLASH MEMORY OF THE LUFKIN ROD PUMP CONTROLLER DELIVERS QUICK UPGRADES WITHOUT CHANGING COMPONENTS. AN ADDED EXPANSION BUS ALLOWS THE UNIT TO GROW WITH YOUR REQUIREMENTS, FROM ADDITIONAL I/O TO COMMUNICATIONS PORTS. INCREASE WELL PRODUCTION ACCURACY AND PRECISION OF DATA IS CRITICAL TO MEASURING OIL AND GAS PRODUCTION VOLUMES AND FLOW RATES. GE'S LWM ROD PUMP CONTROLLER PROVIDES GREATER ACCURACY OF DATA SO YOU KNOW THE EXACT STATUS OF THE WELL AT ALL TIMES, ENABLING YOU TO MAXIMIZE RESULTS. ON AVERAGE, OUR CONTROLS ARE PROVEN TO INCREASE PRODUCTION RATES. MORE UPTIME, LESS MAINTENANCE COSTS BY MONITORING LOADS ON THE WELL WITH OUR ROD PUMP CONTROLLER, WE CAN PREVENT MECHANICAL DAMAGE FROM OCCURRING TO BOTH DOWNHOLE AND SURFACE WELL EQUIPMENT. AS A RESULT, YOU DON’T HAVE TO SHUT THE WELL DOWN AND LOSE VALUABLE OPERATING TIME OR INCUR EXTRA REPAIR COSTS. WITH THE LWM ROD PUMP CONTROLLER, OPERATORS CAN EXPECT A 25% REDUCTION IN MAINTENANCE COSTS. FASTER SHARING OF INFORMATION LUFKIN ROD PUMP CONTROLLER AUTOMATION SOLUTIONS PROVIDE REMOTE COMMUNICATIONS CAPABILITIES THAT SPEED INFORMATION AND OPTIMIZE PRODUCTIVITY. INSTEAD OF HAVING PERSONNEL IN THE FIELD EVERY DAY TO MONITOR THE WELLS, OWNERS CAN COMMUNICATE WITH THE WELL REMOTELY AND DETERMINE WHERE PEOPLE NEED TO BE DEPLOYED THE MOST.

20% Production increase $4 to $6 per barrel reduction in lifting costs 15% Increase in up-time 75% Reduction in workovers 50% Reduction in decline Some benefits seen in two fields were quite dramatic due to the high workover frequency and cost of workovers which made these fields ideal candidates for pump off control with SCADA. Workovers were reduced by 75% in both fields over a period of two to three years. The operator witnessed an increase in production, 25% reduction in maintenance costs which included: surface equipment, stuffing box packing, belt replacements, well head leaks, etc. POC HYDRAULIC TECHNOLOGIES

TESTIMONIALS (CONTINUED) POC's vs. Timers: POC's reduced rod and tubing failures by 30%, reduced surface equipment failures by 15%, reduced fluid pound significantly, reduced bottom home pump failures, and also reduced bottom hole pump failures resulting from rod-parts. POC's also ensured the wells are pumped off reducing fluid levels and therefore decreasing the back pressure on the formation and increasing inflow thereby optimizing oil production. Other intangible benefits include trending, pressure monitoring if so equipped which would also aid in the selection and optimization of casing gas compression. The trending also allowed for chemical program optimization, and reduced chemical costs by 20 -25%. (References available upon request) POC HYDRAULIC TECHNOLOGIES
