Sand Control

PoroMax ScreensMaximizing Performance and Value

Deep water? High build angles? Long reach horizontals? Multilaterals? High rate/high pressure gravel packs or frac packs?

If these are some of the challenges you face,

PoroMax sand control screens provide the

solution. Combining the global gravel pack

experience of Halliburton with the recognized

filtration technology of Purolator, PoroMax is

a top-of-the-line premium screen product,

engineered for optimum inflow area in a

shrouded, sintered laminate screen. These

screens retain the toughness of the highly

successful original Poroplus screen making

them suitable for installations with an

extended reach and/or long open hole and

for installation through a casing window

(such as for multilateral completions), with

or without centralization. With substantially

improved dirt-holding and pressure drop

performance due to the improved inflow

design, PoroMax screens are also suitable for high-flow

applications. They can perform as a standalone or back-up

means of sand control in horizontal openhole completions,

the most common application, or they can be used with

vertical/deviated gravel pack or FracPac applications.

PoroMax sand control screens

do not deform under extreme

pressures due to a proprietary

sintering process. The screens

employ a unique protective shroud that

protects the Poroplate media from

erosion and mechanical damage. PoroMax

screens provide superior plugging resistance,

increased production rates, and longer well life.

Increased Flow Potential And Remedial Options

The PoroMax screen design provides a low-profile screen

approximately 1 2" larger than the outside diameter of the

base pipe. This feature allows for a larger diameter base pipe

than pre-packed screens allow. This design is preferred when

maximum ID/OD ratios for gravel packing are required.

Superior Plugging Resistance

The filter mesh was selected because of its superior

contaminant capacity and erosion resistance. The Poroplate

filter medium captures the desired formation particles on the

outer surface of the screen. The finer contaminants pass

through the coarse downstream mesh layers.

Sintering at over 2000 F in a controlled atmosphere causes metal molecules to migrateacross contact points of the wire mesh layers.Diffusion bonding takes place to form Poroplate

media, a completely integrated structure.

M e d i a

The low-profile open area of the outer protective shroud plus the increasedannular space increases the erosion resistance of the PoroMax screen vs.the standard Poroplus screen. Utilizing the same Poroplate media as thePoroplus screen, PoroMax screens offer superior erosion control coupledwith improved filtration capabilities.

Increased Porosity

Poroplate media have an inflow area

of 30% to 40% compared to a typical

pre-packed screen inflow area of only

3%. As a result, PoroMax screens

provide lower pressure drops,

increased production rates and longer

well life.

Excellent Backwash Efficiency

The Poroplate filter medium has an

extremely uniform pore structure.

And because it is a surface filtration

medium, backwash efficiency is

excellent. Filter cake removal can be

accomplished through a single

reverse-flow sequence.

Media Ductility

Poroplate filter media are fully

annealed. This feature provides

excellent ductility, which allows the

screen to conform to the bending

and flexing of the base pipe in short

radius wells. PoroMax screens have

survived numerous bend, torque,

tensile and crush tests with no loss of

filtration performance.
