WELL SCREENS AND

ACCESSORIES

WATER WELL SCREENSJohnson Screens is one of the largest

manufacturers of stainless steel and PVCwater well screens in the world. With a

high open area,allowing for better access

to the entire formation around the screen;

quickly and completely, resulting in a

LESS MAINTENANCE

The continuous Vee-Wire slot design

water, reducing encrustation rates. The

slot design also resists plugging and

PUMPING COSTS

The high open area of the Vee-Wirewell

screen allows for water to enter the well

freely, resulting in minimal drawdown and

less energy usage by a pump.

DESIGNED FOR OPTIMAL

PERFORMANCE Johnson Screens will analyze the

formation sand and correctly size the

well screen

Proper grade of stainless steel for

maximum corrosion resistance

Noting the depth of the well, correct

combination of wire and rod that

produces a screen with all the

necessary strength

Screen design is determined

by aquifer characteristics and

desired yield

Johnson Screens can supply all of

are needed for installation

SAND CONTROL

The water well screen is a keycomponent of the sand control system,

either as an integral component of the

of sand control. Johnson Screens

patented Vee-Wire technology and

screen failure by better controlling the

sand.

TECHNICAL SUPPORT AND

DESIGN ASSISTANCE

technical support and design assistance.

Support se clude:

Sand analysis of formation materials

Screen size recommendation

Screen installation suggestions

Well construction consultation

Johnson Screens technical staff

includes: design engineers, welders,

technical support personnel and sales

technical seminars, set and pulled

screens, and run pumping tests.

Johnson Screens understands the water

any technical matters.

END FITTING AND SCREEN CONNECTION OPTIONS

The majority of well screen installations

combinations.

Telescope size screens typically use a

Figure K packer on the screen top and a

welded or threaded plate bottom. Pipe

size screens attach directly to the

ADDITIONAL PRODUCTS

Johnson Screens di-electric coupling

and industrial water well completions.

When two dissimilar metals are coupled

less corrosion-resistant metal corrodes

eliminating the contact between the two

metal surfaces.

A di-electric coupling uses insulating

rings which separate the metals and

the life of the pipe and the life of the

for pipe sizes from 1.5 - 24 in.

(38 to 609 mm). Special sizes or

on request.

ADVANTAGES, FEATURES AND

BENEFITS

In the center of the coupling, an

metals from making contact and

causing corrosion of the casing.

This feature extends the life of the

pipe for l s

The coupling has a small OD, only

1.5 to 2 in. (38 to 51 mm) larger

costs by minimizing the size of the

hole to be drilled

The nominal ID of the string is

maintained through the coupling for

full design functionality
