1 DEVIATED WELLS/COILED TUBING Snake Directional wells and wells with coiled tubing have deviations that can prevent ordinary plungers from running up and down the well. Snake s have a flexible core that allows them to move easily around tubing deviations. product overview: The PCS Snake has a tough, flexible, steel cable that allows it to bend and move easily through coiled tubing and directionally drilled wells.

2 HIGH GAS & LIQUIDS Flow-Thru High volume gas and liquid wells require too much shut-in time for a standard plunger to fall. Flow-Thru (by-pass) plungers drop quickly through gas and liquids, requiring little to no shut-in time. product overview: The PCS Flow-Thru is designed to allow the well to continuously produce, reducing or eliminating shut-in time. The unique PCS design opens and closes a by-pass valve, letting the plunger fall against flow, making more trips per day with faster fall times, resulting in substantial daily production increases. popular product styles: A - PADDED SLEEVE BY-PASS B - CENTER BY-PASS C - RING FRICTION BY-PASS U.S Patent No. 7,314,080 A B C

3 SCALE Shock Absorber Down hole equipment is restricting production, causing a pressure drop and creating scale build up. By removing downhole restrictions, costs for chemical treatments and wirelines are decreased. product overview: The PCS Shock Absorber has its own bumper spring built into the plunger, allowing the plunger to run directly off of the seating nipple or standing valve. The internal bumper spring is made from Viton Rubber, which will not lose its elasticity due to age or abuse. By removing the downhole restrictions, chemical treatments and wireline costs are decreased.

4 SCALE Scale Knocker Severe scale in the seating nipple is restricting production. Removing scale from the seating nipple before it builds up decreases restrictions. product overview: The PCS Scale Knocker is a PCS Shock Absorber with a stinger/broach that penetrates the seating nipple removing scale before it builds up. This plunger can be run daily, or as needed for scale removal, reducing chemical treatment and wireline expenses. Scale Knocker (low portion) Tubing Size Standard OD 2 3/ Patent Pending

5 SAND, SALT, COAL FINES Sand Wells are producing sand, salt or coal fines, causing standard plungers to become stuck in the tubing or lubricator. Sand plungers allow for gas to flow through the plunger, cleaning sand from the grooves, allowing the plunger to move more efficiently in the well s tubing. product overview: The PCS Sand is an economical, durable, solid plunger with clean out holes that allow the gas to flow through the plunger, avoiding sand build up and preventing the plunger from sticking.

6 SAND, SALT, COAL FINES Brush Wells are producing sand, salt and coal fines -or- Marginal wells need a better sealing plunger. Brush plungers wipe sand, salt and coal fines from the tubing walls during daily trips up and down hole. product overview: The PCS Brush has a spiral-wound, flexible brush that efficiently removes sand, salt or coal fines. The oversized nylon brush creates an excellent seal despite variations in the tubing. Brush Tubing Size Brush OD Optional 1 1/ N/A 1 1/ N/A 2 1/ N/A 2 3/ / N/A

7 PARAFFIN Solid High gas to liquid ratio wells -or- Paraffin producing wells require a durable, low-cost plunger. A heavy plunger, with a consistent outside diameter, is able to cut through paraffin and has faster fall times. product overview: The PCS Solid plunger is a low cost, durable, solid steel plunger with a grooved surface that is best suited for wells with higher gas to liquid ratios or wells producing paraffin, sand or salt. A lighter version of the PCS Solid is also available.

8 PARAFFIN Ring Paraffin build-up is restricting the amount of gas and liquids being brought to the surface. Ring plungers help remove paraffin by constantly coming in contact with the tubing walls, creating an effective seal and wiping the tubing walls clean before the paraffin can harden. product overview: The PCS Wobble Washer has 21 shifting rings. The continuous contact of the shifting rings against the tubing walls produces a highly effective seal and the wiping action ensures that scale, salt or paraffin is removed from the tubing walls, before it has time to harden, reducing hot oil jobs and paraffin coating. PCS s unique locking system ensures that the plunger cannot come apart even if it becomes loose. Ring Tubing Size Standard Ring OD Optional Ring OD 2 3/ /
