PETROVALVE HISTORY
FIRST DEVELOPED IN ALBERTA, CANADA IN 1987
DEVELOPED TO IMPROVE EFFICIENCY OF HEAVY OILPUMPING AND HORIZONTAL PUMP DEPLOYMENT
DEVELOPED TO ELIMINATE GAS LOCKING IN HIGHGOR WELLS
PETROVALVE ACQUIRED BY FLOTEK INDUSTRIES, INC.CURRENTLY OPERATES AS A DIVISION OF FLOTEK

PETROVALVE UNIQUE DESIGNFEATURES
REPLACED LOOSE BALL OF API INSERT VALVE WITH ASHAFT GUIDED HEMISPHERE ALWAYS CONFINED TOTHE VALVE AXIS IN LINE WITH THE SEAT
GUIDED HEMISPHERE RESULTS IN A LARGER FLOWAREA WITHIN THE VALVE CAGE AND PERMITSOPERATION WITHOUT LOSS OF SEATING EFFICIENCY FLOW AROUND HEMISPHERE PRODUCES ROTATIONWHICH RESULTS IN THE HEMISPHERE CONTINUALLYLAPPING THE VALVE SEAT
EXTENSION OF THE HEMISPHERE SHAFT BEYOND THEEND OF THE CAGE RESULTS IN POSITIVE VALVEOPENING ELIMINATING GAS TRAPPED BETWEENSTANDING VALVE AND TRAVEL VALVE

PETROVALVE DESIGN BENEFITS
IMPROVED FLOW DYNAMICS REDUCES GAS BREAKOUT
IMPROVED SEATING RESPONSE MEANS LESS LEAKAGE AND IMPROVED EFFICIENCY
REDUCED COMPRESSION LOADING RESULTS IN LESS ROD DAMAGE
IMPROVED PUMP FILLAGE IMPROVES PUMP EFFICIENCY
HORIZONTAL PUMPING POSSIBLE WITHOUT LOSS OF EFFICIENCY
SLOWER PUMP SPEEDS POSSIBLE TO ACHIEVE SAME PRODUCTION LEVEL – REDUCES WEAR AND TEAR AND LOWERS ENERGY COST
ELIMINATES GAS LOCKING USING GAS BREAKER TRAVEL VALVE

PETROVALVE APPLICATIONS
PETROVALVES ARE IN MORE THAN 15,000 WELLS WORLDWIDE
EXCELLENT PERFORMANCE IN STEAM ASSISTED HEAVY OIL APPLICATIONS – INCLUDING HORIZONTAL AND LARGE DIAMETER WITH TEMPERATURES IN EXCESS OF 200 C
PERFORMANCE LIFE IN EXCESS OF 2 YEARS IN OIL WELLS WITH HIGH SAND CONTENT
GAS BREAKER USED IN VERTICAL AND HORIZONTAL WELLS AND TO DEPTHS OF 12,000 FEET
GAS BREAKER OPTIMIZATION CAN BE DIFFICULT IN DEEP WELLS AND WHEN PUMPING UNDER A PACKER
PETROVALVE STANDING VALVE USED EFFECTIVELY AS FLOW REVERSAL CHECK WITH ESP AND PC PUMPS

CONCLUSIONS
PETROVALVE DESIGN INCREASES PUMP EFFICIENCY RESULTING IN GREATER FLUID PRODUCTION OR LOWER OPERATING COSTS OR BOTH
GOOD RESULTS IN HEAVY OIL APPLICATIONS
GOOD LIFE IN “SANDY” WELLS
GOOD RESULTS IN HORIZONTAL PUMPING WELLS
GAS BREAKER OPTION CAPABLE OF LIFTING FLUID WITHOUT GAS LOCKING IN VERY HIGH GAS/FLUID RATIO WELLS
PETROVALVES ARE INHERENTLY MORE EXPENSIVE THAN COMPARABLEAPI INSERT VALVES BUT CONSTITUTE A SMALL FRACTION OF TOTAL PUMPSYSTEM COST
DEGREE OF ENHANCEMENT DEPENDS ON RESERVIOR CONDITIONS
