2. Overcoming the challenges
Improved oil recovery methods are fast becoming an essential requirement for all the
mature and marginal oil fields around the world. The ability to identify and unlock vast
amounts of trapped reserves has provided a niche business opportunity for companies
keen to tackle and overcome many of the technical challenges posed.
This is a where SEMJET" Well Technologies and its global partners are leading the way,
by purposefully focusing on the challenges and then resolving them before they arise in the
field. Over one thousand concerns, posed by industry experts, engineers and clients alike,
were used during the research and development of SEMJET’s" multi-functional solutions.
The application of SEMJET’s" new technologies, now enable a client to overcome the
majority of technical challenges they may face, while vastly improving their ability to
enhance exploit their reservoirs and increase production from depleted wells.
• The ability to inspect the condition of the production tubing with in-situ inspection, log
the cement bond and correlate the casing collars, from its built in logging system.
• The ability to provide remedial cementing services, wherever the target zones have
been identified as having poor cement integrity; to ensure suitable zonal isolation.
• The ability to create a number of underbalanced horizontal channels off any wellbore
at a true 90° for the purpose of increasing the overall drainage area of a reservoir.
• The ability to create horizontal channels off any new or old wellbores that have 4.5”
casing or greater; whether the wells are vertical, deviated or horizontal in design.
• The ability to enter mono-bore completions and jet lateral channels at a true 90° in
casing as small as 3.5”, using a secondary, unique coiled tubing system.
• The ability to unlock and stimulate trapped oil reserves, beyond any near wellbore
damage, by displacing acid, specialty fluids or microbial products into the laterals.
• The ability to displace any stimulation fluids at the furthest end of a lateral and back
towards the main wellbore, allowing for deeper formation / reservoir penetration.
• The ability to penetrate the reservoir and open up larger producing channels without
using conventional perforating guns, which damage the formation and are hazardous.
• The ability to create a low pressure, high velocity circulating environment within the
wellbore; to ensure cuttings removal, geological samples and efficient well cleaning.
• The ability to create a series of multi-lateral or bi-lateral channels as a pre-cursor to
frac operations, in a revolutionary, single entry process; in vertical or horizontal wells.
• The ability to create by design a unique radial stacked lateral formation, which is ideal
for directional flooding or the SEMJET" version known as a Radial SAGD" system.
• The ability to re-enter laterals at any time by deploying a packer secured Lateral Re-
entry Guide" primarily used to run lateral sand screens and directing gravel packs.
• The ability to run and set an internal ported casing patch, for the isolation of previous
perforations or to support the casing exit area created during lateral formations.
• The ability to run custom designed Pre-Ported Casing", allowing for lateral channels
to be created without the need for any casing exit tools or loss of casing integrity.
• The ability to track the trajectory of each lateral channel in a 3Dimensional electronic
format, from surface using the latest in micro-coiled tubing technology and sensors.
• The ability work over, pull tubing, jet and stimulate any well under live conditions,
through the deployment of a stand alone snubbing unit, to eliminate killing the well.

3. Whatever you need
In what can only be described as one of the most versatile well optimization systems ever
built, SEMJET" can now perform over 12 independent services from an equipment spread
that is manufactured onto the back of just 3 tri-axle trucks*. Not forgetting that SEMJET"
requires just 4 personnel on location at anyone time to operate all components**.
For international or offshore operations, SEMJET" can also manufacture custom designed
skid mounted units, which are built to order and within the confines of standard 20ft ISO
shipping containers. These skid-based systems are highly mobile, secure and also
conform to lightweight field applications where crane limitations could be an issue.
As an example a complete SEMJET" surface system would comprise of:
1. Wireline logging unit including BOPs and lubricator.
2. Micro-coiled tubing unit including injector and gooseneck (1/2” or 3/4” coil)
3. High pressure injection pumps capable of up to 15,000psi at 10gpm
4. Low pressure injection pumps capable of up to 2,000psi at 10gpm
5. Nitrogen membrane unit and compressor capable of delivery 750scf/m at 2,000psi
6. 4phase production testing meter with constant electronic data monitoring
7. Surface sampling unit with low-micron sediment filters
8. Pre-Ported Casing" cutter and Wrapid Sleeve" application unit
9. Real time data acquisition console with logging, directional and test data functions
In addition to the components that make up the surface system we cannot overlook all the
unique SEMJET" innovations, being their patented down-hole delivery tools and trade
marked processes:
1. MLJ-1 tool, the first generation BHA with a casing exit and 90° lateral jetting tool,
used mainly in vertical or deviated wellbores.
2. MLJ-2 tool, the second generation BHA with a casing exit, 90° lateral jetting tool and
multi-functional underbalanced / N2 circulating sub, used mainly in vertical, deviated
and Hz wellbores.
3. MLJ-3 tool, the third generation BHA, which requires no casing exit tool, but still
enables 90° laterals to be jetted bi-laterally off a horizontal wellbore. This tool also
incorporates the N2 circulating sub, retrievable tubing anchor and protective sleeve
for multi-staged frac operations.
4. HCC-1 tool, the Hydraulic Casing Cutter" is a unique microbotic 2” casing exit,
controlled from surface, with up to 16 orientations for precise lateral placements.
5. LRG-1 tool, the Lateral Re-entry Guide" to enable re-entry of any well, at any time
additional stimulating operations or liners to be inserted into the lateral channels.
6. Pre-Ported Casing" services for horizontal or vertical well bores. Pre-Ported
Casing" is a SEMJET" custom cut process, which is sealed onsite using a CNC
jetting cutter and Wrapid Sleeve" technology.
* Truck models & specifications vary from region to region / manufactured to order.
** The number of personnel & trucks only increase with the deployment of a stand-alone snubbing
unit and pre-ported casing unit, which are project specific.

4. SEMJET" Multi-Lateral Jetting
The Challenge has long been the ability to reach into a reservoir, far beyond any near
well-bore damage using an ultra short radius method and successfully deliver a stimulation
program that can improve declining production; An important ability in today’s marginal
fields.
The Issues are not only limited to the near well-bore damage caused by incompatible
drilling fluids or conventional over-balanced drilling. As studies have also shown damage is
also caused when perforating, shattering the casing cement and plugging off the very holes
it was intended to create. In addition, sand migration and ground sloughing around the
producing areas, will also impair the wells production over time.
Traditional Solutions are plentiful although they all come with inherent problems of their
own. Re-perforating, acid stimulation and fracs are commonly used methods, applied to re-
open the depleted zones again, but without really addressing the underlying problems.
These traditional work-over methods can be very short-term and very costly solutions.
• Perforating creates the desired penetrations but they’re usually short in distance, they
also create thermal glazing problems, issues of gun-debris and the effect of breaking
down yet more of the very cement that is required to maintain the well integrity and
zone isolations.
.
• Acid squeezes often follow and are designed to clean the perforations as well as
penetrating the formation, although the majority of acid used is ‘spent’ just a few
meters out of the wellbore or soaks into fractures before they’ve had any effect.
• Fracs are usually more successful in comparison, but also have similar issues,
following the path of least resistance, into fractures, or filling up the void’s left where
the wellbore cement integrity was lost
previously.
The SEMJET" Solutions offer a range of
integrated services that can assess and repair
a wellbore, prior to jetting and stimulation, the
directing a frac or steam-flooding program.
1. Initial in-situ tubing inspection and CBL
logs will determine the condition of an
existing well, prior to operations starting.
2. Any cement integrity issues can be
reviewed onsite and a SEMSeal"
remedial cement job performed.
3. Once the target zones are logged, the
SEMJET" BHA is then run in hole.
4. Upon exiting the casing, using either a
mill in an existing well, or the SEMJET"
PPC technology in a new well, a series
of horizontal channels will be jetted at
90° from the main wellbore.
5. The channel created will be a predetermined length from 1m to 100m and monitored
from surface using the SEMTrack" 3D trajectory system.
6. By design, the high-pressure jetting nozzle will initially create a 1” pilot channel out to
the extent of the lateral. A stimulation fluid is then displaced through the micro-coil
and the channel is then cut up to 3” using a method similar to back-reaming.
7. The speed of the return cut, the rate and the pressure of fluid being injected will
determine the channel size and overall penetration of the stimulation fluid. Stimulation
will be effective from the furthest extent of lateral back into the main wellbore.
8. Constant hole-cleaning and cuttings removal is possible with the SEMCirc" system.

5. SEMCirc" Underbalanced Wellbore Cleanouts
The Challenge was to reduce the amount of hydrostatic pressure being exerted on the
formation during the jetting and circulating process; in addition to ensuring that all the
cuttings are removed from the wellbore and the lateral channels, enabling a successful
single entry, multi-lateral jetting operation.
Due to the speed at which the laterals are cut, higher velocities are required down-hole and
a gas-lift circulating tool was needed as an integral component to the existing SEMJET"
BHA. This ultimately ensures that all formation cuttings and fluids, created during the
jetting process of each lateral channel are removed and collected at surface.
The Issues in not being able to clean out the wellbore during the jetting of each lateral
channel would result in a limited amount of laterals in any one well and an overall limit on
the distance that each lateral can be jetted.
• Due to the amount of cuttings created during the jetting process, multiple runs would
have to be made in and out of the well with the BHA and swabbing operations
required to clean out the well bore and sump, adding increased time and
unnecessary cost to the project.
• More concerning though, is the potential effect of fines migration, the smaller cuttings
being forced by the hydrostatic head of fluid in the well-bore back down the previously
jetted lateral channels, which could ultimately cause skin damage, blockages and
result in non-productive flow. Something our competitors face in all their projects.
Traditional Solutions are available in the from of a service rig and swabbing process, or
the additional cost of calling out a conventional coiled-tubing system. Days would be added
to the overall project in the case of a swabbing operation and even then not all the residual
cuttings would be retrieved from the wellbore in an effective manner.
Using conventional coiled tubing and nitrogen offers better results in cleaning the well, but
drastically increases the overall project cost.
The SEMJET" Solution allows for the use of a gas
lift method, with nitrogen being injected down to the
SEMJET" BHA. The nitrogen exits through
specifically designed circulating sub and creates a
stream of nitrified fluid that rapidly rises to the surface.
1. A low pressure, high velocity condition is created
in the main wellbore using nitrified bubble
stream to carry cuttings and fines to surface.
2. At surface the cuttings are directed in to a
vented storage tank via a bypass in the
SEMCap" surface sampling system. At any
point in the operations some cuttings flow can
be diverted through a sample pot for capture
and geo-logical analysis.
3. By SEMCirc" creating what is essentially an
underbalanced condition in the main wellbore
and having a balanced condition in the laterals
while they are being created, aids in the rapid
evacuation of the cuttings to ensure no build up
around the jetting hose.
4. SEMCirc" has the ability to work in all well
types, with an emphasis on being more
applicable and more effective in the deeper
horizontal wells.
5. Depending on the density of the returns in any particular well, a compatible foaming
agent would be injected also. Nitrified foam is proven to have a far greater ability in
carrying the cuttings to surface.
