 SINGLE
ISOTOPE
HIGH PRESSURE INJECTOR
Radioactively charged media (methanol water based gel
mixed with radioactive charged glass or aluminum, beads, radioactive liquids,
other propping agents) are injected into the well, using Gel Injector, providing
a source for gamma survey, and evaluation of treatment results.
The Radioactive Gel Injector is generally used in well stimulation
applications such as:
 |
Radioactive Fracture Detection and Evaluation process to determine: |
|
Fracture location with respect to depth |
|
Type of fracture produced |
|
Number of fractures produced |
|
Effectiveness of fracturing methods |
|
Effectiveness of fracturing aids, ball sealers, initiators, plugging
agents, etc. |
|
Communication between zones or perforations |
|
Frac Height Communication |
|
Acid Penetration Evaluation |
|
Radioactive Water Injection Study |
MAIN CYLINDER
|
Made of the highest quality stainless steel which is corrosion and acid
resistant. |
|
For high pressure applications (15000 psi cold working pressure) the
cylinder volume contains up to 100cc of media and for lower pressures
(6000 psi cold working pressure) the cylinder volume can be increased to
200cc. |
|
A specially designed Check Valve prevents well pressure from
penetrating cylinder and uncontrolled discharge of radioactive media. |
|
A "Tee" connection and standard union (1502 or 602 depending
on pressure rating) designed for nominal working pressure are supplied. |
SCREW HOUSING ASSEMBLY
|
A unique ball screw driven discharge mechanism assures highly accurate
and efficient media injection. |
|
Original safety check valve prevents accidental contamination of ball
screw assembly and environment. |
|
Safety latch prevents ball screw from "back driving" in case
of accidental line pressure leak into main cylinder. |
|
Transparent scale provides visual confirmation of discharged media
volume. |
MOTOR DRIVE
| 0.5
HP, 12V DC motor coupled with planetary gear system provides 50 ft/lb of
maximum torque at 22 rpm (approx.) and total weight is less than 30 lbs |
| antivibration
spring loaded nut with safety latch assembly prevents any possible loosening
of motor drive from the main body during operation. |
| Built-in
over-torque mechanical, self resetable, safety device protects the ball
screw |
| High
quality electro-mechanical components ensure proper performance in
temperature range –40 to +70 degrees Celsius. |
| Motor
Drive is made of anodized aluminum alloy and all metal parts are either
plated or made of stainless steel which effectively resist high corrosion |
| Manual
pressure equalizing valve enables pressure or vacuum relief from tightly
sealed assembly |
| Motor
Drive can easily be disconnected from injector and stored in carrying case |
REMOTE CONTROL UNIT (RCU)
|
The
injector is controlled and monitored by the RCU |
|
The
RCU controls the following operation parameters:
 |
Injection speed adjustment
from 0.1 to 100.0 units per minute in automatic mode and greater than
200 units per minute in manual mode. |
|
Two digital backlit displays
provide real time information on injection speed and volume discharged
(in automatic mode only) |
|
Overload and completion of
injection alarm indicator light (LED) |
|
Automatic
and manual mode of operation |
|
Reverse
mode |
|
Solid
state power turn on and totalizer - reset function |
|
Main
power switch is conveniently located on side of RCU |
|
Inject
– alarm reset switch |
|
|
RCU
enclosure is made of anodized aluminum and face plate is splash protected
with clear silicon sheet |
|
RCU
utilizes single printed circuit board made of high grade industrial
components |
|
RCU
is fully tested to be operational in temperature range of –20 to +50
degrees Celsius (optional internal heaters can increase the minimum range to
–40 degrees Celsius) |
|
RCU
is light (approx. 2 lbs), easy to operate, service and maintain. |
