1.0 Introduction to Peak Well Services

Peak Well Services Pty Ltd (PWS) is a company established in Perth, Western Australia in 2002

specialising in the Design, Manufacture & Supply of Down Hole, Slickline Conveyed Intervention

Products. PWS provides engineering and design services supported by product training, after sales

support and field support personnel to run PWS and third party tools when requested.

2.0 Introduction to SIM Lock System

The SIM (Slickline Installed Mechanically set) Lock system is a series of flow control devices

developed for running in monobore well completions or wells where a suitable landing nipple is not

available. The system is based on the patented SIM Lock body and Running Tool which was

developed by Peak Well Services Pty Ltd (PWS).

The SIM Lock system was developed initially at the request of Unocal / Chevron to specifically meet

their well and operational requirements in the Gulf of Thailand. As such the SIM Lock system was

required to:

Operate with Multiple Setting methods

Be operable without explosives, motors or any other delicate electro / hydraulic systems

Provide Multiple Applications

Be User Friendly (100% field serviceable)

Be able to perform in harsh down hole conditions

Be cost Effective

The system as delivered and available to the market:

Is a fully slickline conveyable and retrievable system

Is run and recovered with a conventional slickline toolstring

Is purely mechanical requiring no explosives or electronics

Is run with a common running tool which incorporates drag spring, j-slot and upper slip

arrangement. The running tool is fully recoverable and not integral to the SIM Lock body

Can be run on e-line or slickline firing system and set pyrotechnically, using standard setting

tools or where required to be run on coiled tubing or tubing can be set hydraulically

Is designed so that all pressure components that remain in the well are made of material

conforming to NACE MR0175

Is designed with elastomers rated to a 350 degrees Fahrenheit

Is available in a range of tubing sizes to suit 2 7/8, 3 1/2 & 4 1/2

Is extendable to provide a range of functionality:

Gauge Hanger

Plug System

Straddle System

Integral Gas Lift

Downhole Choke

Suspension Device

The SIM Lock system has been designed to function to suit a range of applications using the SIMLock body as the common component base. The system requires no special hand tools to assemble

or disassemble the various applications and as such it is fully serviceable in the field.

3.0 Applications

The SIM Lock system provides a large range of applications which are all based on and built up from

the basic SIM Lock body:

The simplest and most basic application is as a Gauge Hanger where no sealing mechanism

is required

When the SIM Lock Body is fitted with an elastomeric element it forms a plug body. To create

a sealing device there are a selection of equalising devices to choose from including Melon,

Prong or Pump-Open type options.

As a plug or flow through device it can be used as a suspension device for carrying other

control devices

The plug can then be run as a flowthrough device but fitted with an interchangeable choke to

control fluid flow within the well

The system then can be run with an upper and lower plug body connected by a stackable

straddle system to provide isolation over the desired section to be straddled

The same straddle section can be fitted with an Integral Gas Lift device to provide down hole

gas lift

All of the applications are run with a small number of common running and pulling tools.

3.1 SIM Lock Running Tool

The SIM Lock Running Tool is used to convey and selectively

set the SIM Lock on slickline. The lock can be set at any

chosen depth inside monobore type completions or completions

where existing production nipples are damaged. The Running

Tool is pinned to the Running Tool and conveyed on a

conventional slickline toolstring.

A radial indexing mechanism using variable drag springs

activates a set of slips to anchor the Running Tool to the tubing

wall at any desired setting depth. The SIM Lock is then set by

downward jarring. An overpull is applied against the collet to

confirm the lock is fully set. Once set in place the Running Tool

is released from the SIM Lock by upward jarring.

3.2 SIM Lock Bomb Hanger

In its simplest form the SIM Lock body is used as a carrier for

downhole tools. In such applications it maybe used as a:

Bomb Hanger for carrying down hole gauges

The advantage of the SIM Lock in all cases is that it allows the

tool being conveyed by the SIM Lock to be placed as close as

is desired to the area for pin-point data acquisition.

3.3 SIM Lock Plug

When the SIM Lock is fitted with an elastomeric element and

run with a prong it will then act as a bi-directional plug.

Applications include:

Collision Barrier during drilling operations

Wellhead isolation

Zonal Isolation for water shut off

Zonal Isolation to prevent cross flow / co-mingling

Packer Setting & tubing tests during completions /

workovers

Tubing Integrity testing

Newly perforatedproducing zone

3.4 SIM Lock Carrier Device

With adapters added to the SIM Lock plug, the plug can be

used as a carrier device for:

Carrying down hole screens

To hang storm chokes / velocity valves

To carry corrosion coupons

To carry any other device that needs to be suspended

in tubing where there is no nipple profile or the profile is

damaged. Can be set at precise depth within tubing

where the tool needs to be positioned

In this application the SIM Lock is used to carry a standing

valve. This allows the upper zone to produce without cross flow

to the lower zone. When the zones equalise the lower zone can

produce freely with the upper zone.

3.5 SIM Lock Choke

The SIM Lock body can be fitted with an independently

recoverable Downhole Choke thus allowing the SIM Lock to be

used to choke back well fluids as desired. The SIM Lock

system has a unique arrangement where the downhole choke

can be recovered to surface without recovering the plug body.

This means the choke can be recovered and re-sized to meet

flow requirements without the added runs required to pull and

re-set a plug reducing further runs / time & also removing plug

redress cost.

The SIM Choke can be used to:

Control oil or gas flow between two or more sands to control

cross flow and improve overall reservoir performance

To control gas flow from a gas reservoir below an existing oil

reservoir and thus provide natural gas lift

To control fluid flow from differing reservoirs to give a controlled

fluid mix from the well, for example to balance gas dilutions

between high and low CO

3.6 SIM Lock Straddle System

The SIM Lock system can be fitted with straddle tubes between

an upper and lower packer to provide isolation across the

straddled zone. There is no requirement for a different SIM

Lock device all SIM Lock applications use the same base SIM

Lock components.

The SIM Lock system has a unique selective latch mechanism

on each straddle connector to allow the tubes to be recovered

one at a time should the straddle need to be retrieved. This can

be critical for safety purposes when trying to recover the

straddle section back into the lubricator. If the recovered

straddle system is longer than expected because more than

one straddle tube has been recovered, it may not be possible to

function the Xmas Tree valves thus creating a safety hazard.

The SIM Straddle System can be used to:

Isolate water zones

Isolate unwanted gas flow

Isolate a hole in tubing

Isolate a leaking device within the tubing SPM, SSD etc

3.7 SIM Lock Integral Gas Li ft

The SIM Lock Integral Gas Lift System incorporates a Gas Lift

Choke Sub / Connector that is run within the straddle system

providing controlled gas flow from a gas zone behind the

straddled zone. If required the choke can be re-sized by

recovering the upper straddle tube
