Oil Well controls built to Save Labor, Equipment, and produce more Crude.

OIL WELL SENTRY
The ideal Pump-Off Control. Successfully in use on wells up to 6000 feet deep.

About Us

Oil Well Sentry Inc. Oil Well controls developed in the true birthplace of the Petroleum Industry, Oil City, PA.

Successful Oil Producers have installed a 'Sentry on all their wells.  The amazing control of a "Self Managing" system works wonders for your production with minimum labor.  Never over- pumps, or pumps  without fluid!  Eliminates all the labor of  "well watching" and guessing .

Manage Wells with Pencil and Paper.

Most Producers visit their wells every 2-3 days for wear,  damage,  fallen tree limbs,  vandalism, and jot down the new crude oil production.  It is not unusual on a 90 well lease,  with wells 300 feet apart,  to completely cover all the wells in 2-3 hours, and positively KNOW that all  wells are   1)  working producing crude oil and brine, and 2)  the  actual  production time of each  individual well  every visit.

NEW -Oil Well Sentry controls for Gas or Gasoline powered Wells. You start the engine and the Oil Well Sentry stops the engine at Pump Off

Press Start  on the Control panel, then  manually   Start  the  engine, and all the available fluid will  be produced, and never  pump without fluids.  An Hour Meter indicates actual  pump run time. You will know the real production time of each unit,  each cycle!

Product line

Sentry Controls- Complete

"Complete Controls",   480 vac 3 phase, 240 vac single or 3 phase. Control voltages we prefer,  are 277 vac (480 vac)  or 240 VAC controls. Eliminates transformers.

 Everything required from timers (24 hour as shown, or electronic ), special circuit breakers just for the controls, motor controls that monitor power required.  Also a selector switch for manual or automatic controls. A Control Board  that monitors and records  how long each well pumped, and NEVER lets the well pump "DRY", or after Pump-Off, and a built- in  Alarm Shutdown circuit  !  

Sentry Controls- Add-On Unit

The "Add-On" control uses your existing breakers, motor starters, etc.  for   automatic operations.  Eliminate most of the labor and time of "watching a well pump to pump-off".  By monitoring  and controlling  the oil well's  production prevents any unnecessary operations. and eliminates all the time "watching and guessing " a normal well.

 Three  sensor  types are available: 1) The bridle mounted sensor,   2)  in-line orifice sensor assembly,  3) the new sensor for wells with a Back Pressure Valve.  The Sentry never lets the well pump without fluid.  This greatly extends production  periods between well rebuilds.  The Sentry monitors every pump stroke for normal flow, and records the actual  time of each cycle. After all, what is your  time worth!


Makes a
"Self Managing"  control for  your existing units.  

Freeze Shutdown or High Pressure line Control

Oil Well Sentry also manufacture a shut down control  for non-Sentry units in cases of freezing temperatures, or a paraffin run that raises the line pressure to unsafe limits. The normal Oil Well Sentry's controls, with optional sensors for the "Add-On" or "Complete Control",  have terminals dedicated to an Alarm Shutdown for many different reasons. 

Prevent a tank spillover

 A high fluid tank level sensor for Shutdown Control is mounted  in a stock tank to prevent any overflow spill.   Controls have ability to shut down single well or entire lease to prevent spillover.  Direct  or  Power Line communication available.     

Device compatible with other controls

Multi's Products natural gas Power Unit with the Oil Well Sentry's Pump-Off. The 'Sentry manages the productive time producing fluids, not just operating a timed period. An hour meter records actual production time.


Why the Oil Well Sentry

NOW, a "self -managing control" that monitors the fluid level in the working barrel, and terminates the pump cycle when the accumulated  fluid  just starts to pump- off.   
Time Clocks are required, but not without a Sentry.  Eliminates guessing, watching, and estimating   pump cycle times . Intelligently  monitors  the fluid in the working barrel and stopping  the pumping cycle when the fluid pumps low,  will extend well life because the well never pumps without fluid.  Wear & Tear is much less, and less energy is needed for increased production.   An Hour Meter displays the  time the well was in production.  Never pumps after "Pump-Off" or dry! 

 Increase 10-100% more crude oil at 30% less energy required.

 NOW YOU KNOW EXACTLY,  NOT GUESSING,  WHAT YOUR WELLS ARE PRODUCING!
 

Real Results

  

This well,  located in western Pennsylvania, was drilled by Quaker State in the 1970's. This well had its own stock tank.  It pumped just one 45 minute cycle every day for 10 gallons of Crude Oil.  An "Add-On" Sentry was installed in 2013.  Four pumping cycles per  day were set.  Three days later,  we discovered the well had pumped for only four- 7  minute long production cycles a day  (that's all the fluid it produced)  but increased the volume of crude oil from 10 gallons to 16 gallons a day. 

It  increased actual production by

52 MORE barrels of PA crude oil a year! (Typical-52 x$ 60 =$3,120.)

17 minutes less PUMPING TIME EACH DAY. 

 Less  WEAR  & TEAR (Extends well pulling & re-builds from months to years). 

Eliminating  one " well pull" will  pay for one Sentry, and a lot more CRUDE OIL!  


This result IS typical of our "self-managed" systems.
