Don't guess your pumping times, let the 'SENTRY manage it!

YOU set the rules, the Oil Well Sentry will manage your production times.   Never pumps without fluid,

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 pumps  without fluid and eliminates all the labor of  "well watching" and guessing  pump cycle times..

Manage Wells with Pencil and Paper. Computer not required!

Most Producers visit their wells every 2-3 days for wear,  damage,  fallen tree limbs,  vandalism, and jot down the new crude oil production time.  It is not unusual on a 100 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- Automatic controls for your manually started gas or gasoline engines.

Procedure for start-up:  1) Disconect Jack from engine. Press Start  on the new Control panel and  manually, flip the man-auto switch to MAN,  (2) Start  the  engine.      

3)  Once it is running, reconnect jack and flip switch to AUTO. When all  the available fluid is produced, the unit will automatically shuts down.  An Hour Meter indicates actual  production time. You will know the real  production time of each unit,  each cycle!  Extends time between well "rebuilds" because wear is greatly reduced.

Product line

Sentry Controls- Complete

"Complete Controls",  Finger safe! 480 vac 3 phase with 277 vac controls, 240 vac single or 3 phase.  Eliminate transformers.

 Everything required is there, 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  Also  a built- in  Alarm Shutdown circuit  !  

Sentry Controls- Add-On Unit

The "Add-On" control uses ALL your existing breakers, motor starters, etc.  for   automatic operations.  Eliminate most of the labor and time of "watching a well pump to pump-off". 

 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. 


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 is automated  with the Oil Well Sentry's Pump-Off to shutdown at pump-off. The 'Sentry manages the productive time producing fluids, not just operating a timed period.  An hour meter records actual production time, not just run time!


Why the Oil Well Sentry

NOW, a "self -managing control" that monitors the fluid level in the working barrel or volume of fluid produced, then  stops  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  monitoring  the fluid in the working barrel or normal flow each stroke, and stopping  the pumping cycle when the fluid pumps low,  will extend well life because the well 

never pumps  without fluid.

  

Wear & Tear and well re-building time is much less, and less energy is needed for increased production.  

 An Hour Meter displays the exact 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 has 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  oil from 10 to 16 gallons a day.

 

Annual production increase of 52 MORE barrels of PA crude oil a year!

(Typical-52 x$ 68 =$3,536.)

17 minutes less PUMPING TIME EACH DAY. 

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

 

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


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