The Mill E-Z Wireline Set Composite Cement Retainer utilizes a built-in poppetvalve assembly for remedial cementing or zone abandonment. The poppet one-waycheck valve is opened in conjunction with a stinger assembly and applied pressurefrom surface. Because of its low metallic content, the Mill E-Z Wireline CementRetainer is quickly milled and circulated back to surface using conventional milling,drilling with a rig and tubing, or with coiled tubing.

Once the Mill E-Z Wireline Set Cement Retainer is set, a stinger assembly isattached to the workstring and run to retainer depth. The stinger is then inserted intothe retainer bore and seals against the mandrel I.D. isolating the workstring fromthe upper annulus. Once sufficient set down weight has been established, appliedpressure (cement) is pumped down the workstring, opening the one-way check valve,

allowing communication beneath the cement retainer.

The Mill E-Z Mechanical Set Cement Retainer utilizes a built-insliding sleeve assembly for remedial cementing or zone abandonment.The sliding sleeve check valve is operated by a mechanical setting tool.Because of its low metallic content, the Mill E-Z Wireline CementRetainer can be quickly and easily milled and circulated back to surfaceusing conventional milling, drilling with a rig and tubing, or with coiledtubing.

Once the Magnum Mill-EZ Composite Cement Retainer is set

mechanically, an acceptable workstring weight is then set on the retainerfor a more secure fit. During the cementing operation, the hydraulicforces will add or subtract weight to the cement retainer. The operatorshould complete the hydraulic calculations to prevent overloading orpumping out of the retainer. Now the cementing process can begin.

General

The purpose of the Mill E-ZCCRis to isolate a well bore in various temperatures and pressures so remedial

cement work can be conducted. The Mill E-Z line of composite products is made of a patented design of

materials that drastically decreases the amount of time it takes to drill out or remove with rotary or cable tool

methods. The Magnum Mill E-ZCCRtakes much less time to drill out or remove when compared to cast iron

cement retainers.

All Mill E-Zproducts are designed slim to enable clearance in a wide range of casing weights while maximizing

fluid bypass to aid in fluid displacement even when heavy mud permits.

Slide Valve Feature

The Mill E-ZCCRis designed with a slide valve in the lower section of the retainer which is pressure balanced in

the closed position in order to restrain high pressure differentials that are encountered in typical well conditions.

This slide valve system is often preferred throughout the industry when compared to poppet-valve or ball-valve

constructions due to debris that is found in all wells.

Stinger

The Mill E-ZCCRutilizes its own unique stinger (SSA) manufactured by Magnum Oil Tools. This stinger will be

secured to the tubing and once the tubing and stinger is landed, will actuate the slide valve in the open position

in order to pump cement through the tool.

Hydraulic Forces Applied to Mill E-Z CCR

Pressures applied to the casing and tubing effect the stinger sub and tubing during cementing and pressure

testing operations. These forces are variable and are affected by the area of the cement retainer seal bore, casing

and tubing pressure changes at the Mill E-ZCCR, tubing size and weight and fluid weight.

An increase in casing pressure at the Mill E-Z CCRwill lift the tubing which can cause the Slide Valve to close.

The amount of force generated by a casing pressure increase is calculated by the following formula;

(Casing pressure x Area of tubing)

- Seal bore area of the tool

= Force at the Mill E-Z CCR

A pressure increase in the tubing exerts a lifting force at the top of the string which will reduce the effective hook

load. A pressure increase in the tubing at the Mill E-ZCCRwill tend to hold the Stinger Sub in the tool and

keep the Slide Valve open. The net of these two forces is upward and is equal to the increase in tubing pressure

multiplied by the area of the seal bore in the cement retainer. When this force is equal to the tubing weight, any

additional pressure will lift the tubing and allow the Slide Valve to close.

Therefore, the minimum setting depth will depend on the applied pressure changes in the tubing and casing acting

to lift the available tubing weight.

The amounts of tubing and annulus pressure that can be applied are limited for any size and length of tubing.

When the total of the forces is equal to the weight of the tubing in fluid, an increase in either tubing or casing

pressure will raise the tubing and close the Slide Valve. However, the cementing pressure may be increased if the

casing pressure is decreased and vice versa.

MILL E-Z COMPOSITE CEMENT RETAINER






10/13

Hydraulics of Cementing Operations:

Various forces created by pressures applied to the casing and to the work string act on the Stinger Sub Assembly

(SSA) and work string during cementing operations. These forces and their effects are governed by the size

of the Stinger Sub Assembly, the size, weight per foot and length of the tubing or drill pipe, the mud weight, theannulus pressure and the work string pressure.

Annulus Pressure

When Tubing OD is greater than the Retainer Bore, the annulus pressure tends to lift the Stinger Sub Assembly

upward trying to pull it out of the retainer. This force is equal to the annulus pressure (at the Cement Retainer)

times the difference between the area of the tubing OD and the area of the Cement Retainer Bore.

When the Tubing OD is less than the Retainer Bore, annulus pressure tends to push the Stinger Sub Assembly

downward holding it in the retainer. This force is equal to the annulus pressure (at the Cement Retainer) times the

difference between the area of the Cement Retainer Bore and the area of the tubing OD.

Tubing PressureWhen the Tubing ID is greater than the Retainer Bore, the tubing pressure tends to push the Stinger Sub Assembly

downward holding it in the retainer. This force is equal to the tubing pressure (at the Cement Retainer) times the

difference between the area of the tubing ID and the area of the Cement Retainer Bore. Also any pressure applied

to the tubing exerts an upward force on the top of the tubing string equal to the tubing pressure times the area of

the tubing ID. This upward force reduces hook load but does not reduce the original slack off weight on the Stinger

Sub Assembly until the hook load is reduced to zero.

When Tubing ID is less than the Retainer Bore, the tubing pressure tends to lift the Stinger Sub Assembly upward

trying to pull it out of the retainer. This force is equal to the tubing pressure (at the Cement Retainer) times the

difference between the area of the Cement Retainer Bore and the area of the tubing ID. Also, any pressure applied

to the tubing exerts an upward force on the top of the tubing string equal to the tubing pressure times the area of

the tubing ID. This upward force reduces hook load but does not reduce the original slack off weight on the Stinger

Sub Assembly until the hook load is reduced to zero.The amount of weight that must be set on the Cement Retainer to keep the Stinger Sub Assembly in place and

the Sliding Valve open depends on both the pressure in the annulus and in the work string. The amount of work

string and annulus pressure that can be applied will therefore be limited for any size and length of work string.

Use the Area (in sq. in.) Acted Upon by Tubing and Annulus Pressures table and the calculations in the next

section to determine if the Stinger Sub will be lifted out of the retainer bore and the Cement Retainer Sliding Valve

will be closed. Additional set down weight or changes in work string and annulus pressures will then be needed to

keep the Stinger Sub Assembly in the retainer and hold the Sliding Valve open.

How to Use Area Pressure Chart for the Mill E-Z Composite Cement Retainer

The values given in the chart on the following page Areas in Inches2(Millimeters2) Acted Upon by Tubing and

Annulus Pressures are printed shaded and unshaded. These values are not only the number of square inches

acted upon by the pressure change, but also the direction of the resultant force. The areas shown unshaded willcause, with a pressure increase, and downward force tending to keep the Sliding Valve open. The areas shown

shaded will result in an upward force, or a force tending to close the Sliding Valve.

When the net force is upward additional setdown weight or altered annulus pressure must be used to keep the

Valve open.

Note:columns 1, 2, 4, 5, 6 and 7 must be multiplied by the change in pressure at the tool. Column 3 must be

multiplied by the tubing gage pressure

1. Multiply the change in tubing pressure at the tool by Columns 1, 4, or 6, whichever is applicable.

2. Multiply the change in annulus pressure at the tool by Columns 2, 5 or 7, whichever is applicable. If the total

of these two forces is tending to close the Sliding Valve additional set-down weight is required to overcome the

new upward forces.

3. Multiply the tubing gage pressure by Column 3. Since Column 3 is always shaded, the resulting force tends toclose the Sliding Valve by lifting the work string at the surface, This force is restricted to reducing the hook load

until the hook load is reduced to zero. Any additional force will then act to lift the tubing string and Stinger Sub.

Add all three forces. If the result is a force tending to lift the Stinger Sub the Sliding Valve will be closed. Since

hook load is the limiting factor, high pressures at relatively shallow depths might be prohibitive.
