TD Solutions –Specialty Tool, HydroGRS™
HydroGRS™ (Hydraulic Guide/Reamer Shoe) is a guide shoe designed to assist in
getting the casing to bottom in difficult environments saving time and overall costs. The shoe
has a proven track record of getting casing to bottom in a significantly shorter time when
swelling shales, ledges and/or washed out areas are hampering the ability to get
casing to TD successfully. The rotary nose is free to rotate as needed to
“follow” the hole while running casing but can be rotated with
pump pressure to actually ream the hole if necessary.
5” to 9-5/8” tool designs available
As an innovative casing

Accelerate stimulation operations
Enable horizontal multi-stage initial hydraulic
fracture treatments and re-fracturing
applications.
Benefits
Like all liquids, fracturing fluids tends to follow the path of least resistance. This can
result in over-treated zones, untreated perforation clusters within a stage. DDB is used to
increase fracture network complexity by blocking off the path of least resistance and
redirects the frac fluids to untreated perforation sets within the stage.

WL Logging – AUI (Annular Ultrasonic Imaging)
AUI, Annular Ultrasonic Imaging Logging is an advanced cased-hole logging technology utilizing detection of
echo amplitude, time of echo and echo attenuation mechanism. AUI provides precise evaluation of cement
bond quality with 360°imaging profile. The casing OD & ID, corrosion and stand-off information can also be
obtained simultaneously. It has been utilized for cement bond imaging analysis on a large number of wells both
home and abroad.

Minimize well-down time & maximize production time.
Protect reservoir
Electrical Submersible Pump (ESP) meets the trend of oil

exposed either. The unique advantage of Vertechs
Rigless ESP System is that rig facility or hoist intervention

Rigless ESP System
The core components contain Wet Connector, Space-
Out Assembly, and Hanger Assembly,
Wet Connector:The stab-in wet connector which combined
at the bottom of ESP motor provides channel for flow and
accepts wet connector assembly inside.
Space-Out Assembly:It has two main functions,
compensate length extension and insure insert action
precisely & eliminate ESP vibrating and shaking against the
wet connector.
Hanger Assembly:The hanger assembly can support the
system’s weight, prevent axial and radial moving of center
