workover rig weight indicator quotation

Our mini weight indicator systems, also called “midget indicators”, are ideal for small work over rigs, water well drilling rigs, and geothermal drilling. Our complete mini weight indicator systems are mounted in a compact box for convenient transport and are ready to use, right out of the box. No assembly or loading is required. The load cell attaches easily  to the rig without the need for a deadline anchor, and everything you need to install this system is included. Our indicators are designed to provide extremely accurate weight measurement, and the large dial is easy to read at a distance. The 6″ gauge is fluid-filled to resist shock, vibrations, corrosion and dial bounce. This hydraulic system is complete, needing no external power source.

Crown deflection weight indicators are complete portable weight measurement systems that can be set up near a well operator or mount on a mast or derrick.  For years, this style and model of weight indicators have been favored for use drilling rigs because of its simplicity and effectiveness. Our deflection weight indicators come with ten dials to simplify the process of operating on multiple rigs.  By the simple process of changing a dial, you can switch between measuring the drill line size and the number of lines strung. The deadline diaphragm operates by measuring the converted hydraulic pressure force from the tightened drill line, which is then registered by the gauge and displays the weight.  Designed to be used on small rigs or well service units that do not have deadline anchors, Crown clipper weight indicators provide accurate weight measurement with two pointers on one gauge. Each clipper weight indicator consists of an inner and outer dial, with the yellow pointer indicating total hook load, and the Vernier (white) pointer indicating weight on the bit. Our clipper weight indicators are durable, reliable, and dependable. Being made of only the most sturdy materials, our deflection (clipper) weight indicator systems stand up to the harshest conditions. The steel case offers compact storage and can be moved from job to job, protecting the clipper system from weather and day-to-day wear.

Matherne Instrumentation’s pad type weight indicator systems are used in applications where either there is no dead line or a double fast line is being used. Pad type load cells detect mast loading under mast jack screws independent of reeving configuration. Our system is housed in a heavy duty steel box with removable front and back doors for added protection. A two-inch coupling is welded to the bottom of the box for easy installation and high visibility.

We"re proud to supply our weight indicator systems to clients throughout Odessa, TX; Midland, TX; Houston, TX; Lafayette, LA; Houma, LA; Pittsburgh, PA; and Williston, ND.

Matherne Instrumentation’s snubbing indicator is a standard 8.5” weight indication instrument designed to give accurate readings during snubbing and hydraulic workover operations.

Matherne Instrumentation’s differential indicator is designed to give accurate readings for pipe light and pipe heavy indications in a single 8.5” weight indicator.

Panel mount and box mount versions are available, in either English or Metric divisions. Each system is comprised of a diaphragm type load cell, high pressure hose assembly with disconnects, 12" or 16" indicator with complete dial set and damper assembly and recharge kit consisting of hand pump and (1) qt. of instrument fluid. Heavy duty steel box or console for mounting of additional gauges is also available (optional).

A deflection type weight indicator, also known as a line scale or clipper, is ideal for use with work over rigs and small drilling rigs. The complete boxed unit includes a 12” Gauge with interchangeable dials, hose and loadcell. The unit is highly portable and durable.

Removing the wellhead slips requires that the pipe string be lifted to take the string weight off the wellhead slips. The force required to move the pipe upward may be greater than the safe pull force of a workover rig and sometimes even greater than a drilling rig. A Casinjac can be used to safely apply the necessary pull force.

If the pipe parts up the hole or above the ground the energy released puts the rig and personnel in danger. Pull subs should be inspected carefully before use, they should have a usable pipe collar on top, be the proper grade and weight and also be of sufficient length.

In order to maximize the recovery of casing it is important to work the casing. Working the casing involves lifting and lowering the casing using a Casinjac and lifting and dropping the pipe using the work-over rig. This process conditions the hole and allows greater pipe movement up and down the hole. This process is continued until the casing no longer moves downward. The casing is then in a worked down condition. Sometimes it is necessary to move the casing up and down using the Casinjac in order that the rig can pick up the casing upward enough to work the casing down effectively. Usually the forces used to work the pipe do not exceed 80% of the listed tensile strength of the casing and/or its joint strength whichever is less. The work-over rig is used to work the pipe down hole by picking it up and dropping it to effect a spudding action which allows the pipe to move down through areas in the hole which are impeding pipe movement. The casing can be marked using a crayon which can be used to monitor pipe movement. When the casing quits moving upward or downward a free-point procedure can be performed to determine the amount of free pipe.

Using work-over rigs. The work-over rigs pull the string weight, set the brake and mark the pipe. The rig then pulls an additional amount of force (stretch force) and marks the pipe again. The distance between the marks represents pipe stretch caused by the stretch force.

The problems encountered when attempting to free-point with a work-over rig are as follows:The inherent inaccuracy of weight indicators and the infrequent calibration of same.

The work-over rig is incapable of maintaining a constant pull force as the pipe moves up-hole. The inability to maintain a constant pull force as the pipe moves up-hole results in an inaccurate stretch determination.

When the rig"s pull force increases the rig "squats". its wire rope stretches, and the matting boards/cellar beam subsides. It is not possible to determine the effect on the stretch measurement these variables cause.

Sometimes the work-over rig cannot pull the string weight, sometimes it cannot pull the string weight plus a reasonable stretch force. and often it cannot pull the string weight plus two consecutive stretch forces much less a third consecutive stretch force.

The use of electric wire-line tools to free-point. This method is used to free-point stuck drill pipe and to free-point casing in work-over operations and is used less often during plugging and abandonment work. Usually a drilling rig or a work-over rig is used to move the pipe string, The free-point tool measures pipe movement over a narrow range (about 6 feet or so). The free-point tool is positioned in the hole where it is assumed that the pipe is 100% free, the rig applies a specified pull force and the tool indicator is adjusted to read 100%. The tool is then lowered to a lower depth, the pull force is applied, and another reading is taken to indicate pipe movement and compared to the initial reading. The tool is lowered to different intervals and readings taken until no pipe movement is indicated,

The following has been observed when free-pointing using wire-line tools and methods.A pull force is chosen that is within the capabilities of the work-over rig or drilling rig and often well below the safe pull force of the pipe string being free-pointed. The pipe could move at a lower depth is the pull force is sufficient.

Using a calibrated digital pressure indicator and an encoding linear transducer lift forces and pipe movement can be measured as accurately as any method currently available.
