Lee Oilfield Service Ltd.

Following is a list of jarring and bumping equipment available:

HYDRAULIC FISHING JARS

The L.K. type Fishing Jar is of our latest design and is manufactured from 4340 HTSR materials or better. All parts are designed to withstand the most severe jarring conditions and provide longer jarring life. When necessary we can provide exotic coatings to seal areas to extend seal life when well bore conditions are such that chrome coatings fail.

FULL BORE TUBING JARS

Occasionally during work over operations Full Bore Jars are required. The Lee Oilfield Full Bore Jars are manufactured from high tensile and yield materials to provide you with effective jarring loads even with the larger inside diameter.

COIL TUBING UP JAR AND DOWN JAR

Because of changing methods of oil well servicing Lee Oilfield have recently designed and proven small Hydraulic Jars for coil tubing application. Both Jars can be run at the same time but are separate tools so that they can be positioned in the most advantageous areas of the assembly for the most effective jarring effect whether it is up or down. This is important because of the limited amount of weight bars which can be run at times. The Down Jar has an adjustable mechanical lock to allow the operator to feel bottom without the Down Jar firing prematurely.

SURFACE JAR (HYDRAULIC)

The Lee Oilfield Hydraulic Surface Jar is a very rugged and reliable tool. This tool is preferred by many because it is very simple to operate, being hydraulic you only pull the desired jarring load and wait for the Jar to release and free fall for 48''. To repeat the action you simply close the Jar and pull the desired amount again.

SURFACE COMPOUNDER

SURFACE DRIVER

The Lee Oilfield Surface Driver is used along with the surface jar on occasions when you are stuck off bottom and not enough pipe stretch to activate a surface jar properly, or on slant rig operations when the bumping weight can not fall efficiently to drive the fish loose. When using the Lee Oilfield Driver you energize the Driver through a distance of up to 18" depending on the amount of pull. When the surface jar releases the Surface Driver pulls the weight above it downwards accelerating the weight mass downwards creating a huge down-ward impact when the Surface Driver is fully closed.

COMPOUNDER (INTENSIFIERS)

A Compounder is used to amplify your jarring load when run with a Fishing jar. The main features of a Compounder is that you achieve a harder jarring impact with less drill collar weight. In cases where you are jarring in a deep well and relying on drill pipe stretch to lift the drill collars for the upward jarring action the hole drag resists upward movement of the drill pipe reducing the jarring effect. With a Compounder all the upward movement happens between the oil jar and compounder. Also in very shallow welts a compounder is very effective because it simulates pipe stretch. In all situations when jarring with a Compounder there is very little movement on surface therefore reducing any damages to the rig and surface equipment.

COIL TUBING COMPOUNDER

The Lee Oilfield Compounder is a two way tool which provides a much harder blow to the Hydraulic Jars making jarring much more effective either upward or downward. At times when you are restricted to the amount of weight bars that can be run, a Compounder will greatly assist the jarring action.

FISHING BUMPER SUBS (MECHANICAL)

The Lee Oilfield Mechanical Bumper Sub is a very effective tool for fishing purposes because we manufacture these with a stroke of up to 60''. These tools with the longer stroke are ideal for milling purposes because you can use a predetermined amount of weight below the Bumper Sub and feed off the bumper sub stroke to maintain constant weight on the mill.

OIL BATH FISHING BUMPER SUB

The Oil Bath Fishing Bumper Subs are used to provide a downward blow during fishing operations. The Lee Oilfield Oil Bath Bumper Sub is manufactured from 4145 HTSR materials or better and are designed with a very rugged spline system which can be run in the open or closed position for long periods of time. The normal stroke for the Lee Oilfield Oil Bath Bumper Sub is 20'' but on request we can vary the stroke length.
