The AX-L Shale Shaker

The AX-L concept

Philosophy

The AX-1 shaker has revolutionised the deepwater shaker market by offering a significant increase in processing

capacity in a smaller footprint coupled with the ability to retain bridging materials while reducing drilled solids

concentrations.

Underpinned by this successful approach, the AX-L shaker evolves the concept further by offering an even more

compact shaker system which delivers the four things most desired by both operator and rig owner:

o Ability to handle large circulating rates in respect to fast, top-hole drilling

o Improved separation and reduced screen costs through 'sequential' screening

o Sized Material Retention™

o A user-friendly design with low-maintenance components

Dual Modes

The 'smaller rig' market now has the opportunity to employ dual screening modes in a cost-effective and

ultra-compact system. The triple-deck AX-L, with an effective screening area of 3m2, can operate in either parallel OR

series modes:

o In parallel mode, fluid handling capacity is increased by 'load sharing' the flow between the middle and lower decks;

o In series mode the fluid is consecutively screened through the three decks – thereby optimising solids removal

efficiency and the life of the ultra-fine screens employed.

Sized Material Retention™

Drilling fluids are more frequently being engineered to contain specifically sized particles. This can be either

conventional lost circulation materials to combat significant downhole losses, or specifically sized material to bridge

fractures and pore spaces. This allows higher fluid densities – often above the fracture gradient – to be employed.

This results in:

o Reduced whole fluid losses in depleted zones

o Reduced number of casing runs

o Increased margin of safety

The AX-L increases the efficiency and cost-effectiveness of these fluid formulations by retaining the sized particles on

the middle deck while removing the larger and finer drilled solids on the upper and lower decks.

Summary of Benefits

Capacity: In parallel mode the AX-L delivers comparable screening area to conventional dual-deck

shakers within a significantly smaller footprint.

Improved Separation: When configured for series mode, the AX-L transforms into the ultimate fine screening

machine by allowing sequential screening AND reduced screen costs.

Flexibility: With options for parallel, series and Sized Material Retention™ the AX-L can now offer the

levels of flexibility only before seen on large, offshore rigs.

Footprint: Because the AX-L is effectively 60% the footprint of a standard dual-deck shaker, the space

and weight required for installation is greatly reduced.

Reliability: The AX-L combines proven components from the AX-1 shaker basket structure with a

field-proven, ruggedised drive system components to increase up-time and reduce

maintenance costs.

Screens: The AX-L uses the massively successful AX Screening System (as employed on the AX-1

shaker).
