COMPANY PROFILE
Welljet Energy Services is located in
Houston, Texas, USA
We are dedicated to providing
LATERAL JETTING SERVICES and
Related oilfield services to clients
worldwide
EXPERIENCE
Highly Experienced in Lateral Jetting Technologies
and Techniques
Over 40 years of accumulated Lateral Jetting
experience
720+ wells completed worldwide using Lateral
Jetting Techniques
LATERAL JETTING APPLICATIONS
EOR – ENHANCED OIL RECOVERY
Oriented acidizing/fracturing techniques.
Well Completion – Replacement of damaging perforations in well
completions – Reduction in damage caused by perforating.
Coal Bed Methane Applications
Well-bore casing and tubing cleaning.
CHALLENGES WE CAN SOLVE
Production declines in oilfields.
Low production due to formation damage near the well bore.
Undeliverable remaining hydrocarbons from marginal or mature oil
and gas fields.
Cuttings from the lateral. Deposited to Rat Hole.
WELL & FIELD SELECTION
Well Selection is very important and we want to make sure that we
make every effort to have success. Not every well will qualify as a
candidate for lateral jetting.
Kerui’s geologists and reservoir engineers will work closely together
with client to evaluate and select wells through reservoir simulation,
log interpretation, and modeling.
Optimized field selection for multi-well projects.
Core samples will be evaluated for optimum nozzle selection.

WELL SELECTION PARAMETERS
Oil & Gas wells up to 8000 ft. depth with riser. Wells at depth of 8,000-16,000 ft.
will require an injector head.
16,000 ft.+ Evaluation
Casing size: ranging from 4.5”-9 5/8”.
Casing grade: J55, N80 and P110. Well deviation: no more than 35°
deviation of well-bore.
Well must have good casing cementation.
PROCESS - STAGE 1
• Pull rod and tubing with work-over rig.
• Prepare cased-hole for lateral jetting process.

BENEFITS OF LATERAL JETTING
The lateral hole created will improve the flow channel, and increase the
migration efficiency deep into formation.
Well-bore contact with reservoir is greatly increased!
Lateral channel increases conductivity of the reservoir to the well-bore.
Greatly increases production!
Dramatic Increase in Well-Bore/Reservoir Contact

FORMATION TESTING
This test formation was sent to us by KU University Of Petroleum, Dr. Barati.
This formation had several attempts to penetrate by using old technology by
several of our competitors and failed with Welljet’s Energy Services USA new
technology we were successful in penetrating formation.
So with use of new rotating nozzle and our new FF01 chemical we can increase
flow channel to well bore with no damaging of formation like conventional
perforating will do.

• 4 X 200 ft. laterals on one horizon.
• Increased first year production from 13,400 bbls to 29,000bbls
• In addition to more favorable decline rates, the estimated ultimate recovery of the
reservoir is also increased due to application of laterals.
