EEST-500K SERIES MODULAR RIGLESS PULLING UNIT

EEST traditionally Rigless technology has been developed over ten years with multiple downhole tools for plug and abandonment of oil and gas wells. These technologies are known as Modular Rigless Pulling Unit.

Though Drilling Rig designs are different, the EEST Rigless unit proven modular technology behind them is the same, but the most significant difference is cost impact.

Modular Crane Pedestal System

- The lifting capacity (70 tonnes) allows the installation of modules and components outside the reach of the platform crane. Alternatively, offshore contractors used expensive crane vessels to install these modules.
- With such a lift, the first few meters are critical. The waves move the vessel up and down, a movement that is independent of the lifting configuration on the platform.
- The diesel-hydraulic power pack operates the winches, making the lifting configuration independent from the offshore platform utilities. The footprint of the lifting arrangement is flexible.
- The loads during the lifting operation can be introduced into the strong points of the platform by altering the base frame or directed to the master skid beam. The EEST engineers have standardised the footprint arrangement for quick mobilisation.
- With state of the art, EEST Energy designed an extension deck to install on top of the main modular crane beam, which provides usable areas for maximising platform space while working with the Rigless unit.

Downhole Cutter & Fishing Tools

We own the mechanical cutters and fishing tools to reduce the number of third-party rentals on location.

Our Mechanical Tubing and Casing Cutters:

- Other methods of cutting the tubular have been researched; there are savings to be had in time. However, costs outweigh the time savings.
- The preferred method of cutting the casing is the mechanical casing cutter due to efficiency and costs.
- Specific carbide design and alignment technique on cutting knife is making faster cut experiences and cost-saving
- Knife redress by EEST tool specialist on location whether offshore or onshore makes most time and benefits with cost-saving.

Cold Cutting Equipment - Portable Guilotine pipe saw

Portable Guilotine pipe saw to cold cut pipe ranging from 2 inch - 32 inch. Their compact design and easy setup make it the ideal saw for pipeline operation, refineries, processing plant, well P&A, and anywhere a fast, safe cut, and hot cut does not allow. In use virtually everywhere, they're strong yet light weight, simple to mount and operate.

EEST four Guilotine models available, from smallest to largest, are the Super C, Model D, Super D, and Goliath. All set uo quickly with a positive chain mounting system that uses a machined cast iron "V" saddle for perfectly square cuts. Operation is easy with finger tip feed control, and all feature an orbital cutting motion that lifts the blade on the return stroke, dramatically extsnding blade life. They cut common pipe material in virtually a y position, horizontal, vertical, or anything between.

Features

- Rugged yet compact design requires minimal operating clearances
- Capable to cut single or multi pipe range from 2 inch - 32 inch
- Fast setup & cutting, both horizontally and vertically.
- Optional autofeed and autoclamp.

GATE VALVE DRILLING
Our Hot Tapping Services

Relieve trapped pressure while online

This is a safe process of controllably drilling into pressure-containing equipment. EEST hot tapping enables a connection to anulus valves on wellheads, tubing, trees, or piping for controlled entry to relieve trapped pressure. EEST Hot Tap unit is capable of drilling larger holes with extended stroke. The examples of why this would be done

- Tapping stuck valves on a Xmas tree, drilling out the valves, relieve trapped pressure, and replace new valves.
- Tapping drill pipe or other tubulars have pressure trapped inside.
- Tapping production flowlines to change out a damaged section without the need to stop the flow.
- There are many and varied applications.

Features:

Features

- Drill size range 0.5” to 18” hole specifically.
- Light and portable unit.
- Max operating temperature 392ºF.
- Pneumatic driven with manual feed.
- Hot tap saddles clamp ranging from 1.5 inches to 12” inches in diameter.

LAYDOWN SYSTEM

Pipe Laydown System

EEST PIPE LAYDOWN AND HANDLER is fully hydraulic and self-contained. Engineering made adjustable drop-down jacks stabilize the unit beside EEST Rigless Pulling Unit on-site locations. The pick-up and lay down of the tubular is achieved hydraulically eliminating the use of cables or handless. Modern and Flexible in design, it utilizes to share with Rig diesel-engine hydraulic powered technology to provide the highest quality, cost effective, and efficient pipe handling services available.

Saves Time and Reduces Costs

- EEST PIPE LAYDOWN AND HANDLER can place a joint of tubing, drill pipe, and casing from the workover basket to the floor in as little as 30 seconds. It picks up and lays down pipe rapidly. A quick return on your operation is achieved through the reduction of personnel, task time, and the risk of exposure.
- EEST PIPE LAYDOWN AND HANDLER provide your operation with a significant cost advantage while enhancing the company's safety profile.
- EEST PIPE LAYDOWN AND HANDLER provides a safer way to handle pipe in Rigless and Workover operations. The potential insurance savings can be a major benefit because the risk of exposure that employees have from otherwise handling the pipe is greatly reduced.
- EEST PIPE LAYDOWN AND HANDLER provides fast, efficient, trouble-free pick up and lay down capabilities for a nominal initial cost. It takes the backbreaking labour out of the equation and allows hands, feet, and heads to be kept out from under the threat of "falling pipe"--a serious and common cause of oilfield accidents.

Why EEST Plug and Abandonment

Our key to a successful well plug and abandonment is to use "Modular Rigless P&A" to complete well barriers and retrieve all tubular related from the ground.

The barrier consists of temporary and permanent seals that will secure the well long after the abandonment, reducing corporate liability and potential environmental impact.

By present technology and method of well plugging and abandonment, EEST integrated Rigless plug and abandonment services are the solutions of simple and traditionally of success and reliability.
