We engineer and develop technologies that are needed to further optimize drilling
operations and reduce the overall cost of the operation. The following tools and
solutions are now available.
Shock and vibration is increasingly acknowledged to be the source of unnecessary
expense when drilling a well. The ESM (Environmental Severity Measurement)
Logger is designed to put reliable shock and vibration data in the hands of
drilling experts so that they can use this vital information to effectively
implement procedures and practices which will control these expenses. Shock and
vibration analysis will aid in providing a better understanding of drilling
dynamics.
The ESM Logger incorporates the following features:
- The ESM Logger measures and records data using 3 accelerometers in each of 3
axes; X, Y, and Z. Data is recorded to memory for post well analysis.
- The rugged and compact design allows the ESM Logger to be installed anywhere in
the drillstring or bottom hole assembly.
- Multiple ESM Loggers can be run in the drillstring at the same time.
- The ESM Logger is used to gain a better understanding of drilling efficiencies
through shock and vibration data collection and analysis.
- The ESM Logger is used to correlate shock and vibration characteristics to
drilling parameters such as drilling performance or downhole failures.

The Anvil is to be used in tight wellbores in an effort to unstick the drill
string that has become mechanically wedged into the formation. The
bi-directional jar action gives the operator the ability to work the jar in the
uphole or downhole directions. Accidental firing of the jar is prevented by a
mechanical latch that holds the internal mandrel in place during tripping and
drilling operations.
The Anvil incorporates the following features:
- Hydraulic delay upstroke, mechanical downstroke
- Internal Lee Visco Jet metering for hydraulic delay
- Large through bore for high flow rates and MWD sonde retrieval
- Can be used in directional, horizontal, and extended reach wells
- Internal mechanical latch prevents accidental firing
- Extra long stroke allows the operator to deliver massive jar impacts

The Typhoon is designed to ream out sections of high frequency wellbore
spiraling, sections of parallel misalignment, key seats, and dogleg tortuosity.
The reamer does this by combining optimized placement of cutting structure and
hole cleaning with a rotational reaming capability. The reamer body incorporates
two sets of cutting structures into two integral blade stabilizers, one oriented
in the downhole and the other oriented in the uphole direction. Polycrystalline
diamond cutters (PDC) are brazed into a replaceable wedge block located in the
ends of each of the stabilizer blades.
The Typhoon incorporates the following features:
- Chevron Style Stabilizer Blades: The two integral blade stabilizers have a
combination left hand/right hand blade wrapping to provide 360° support around
the circumference of the reamer and provides low torque characteristics.
- Cuttings Agitation and Flow Accelerator: Between the two stabilizers, a rotor
and a contoured ‘bulb’ (flow accelerator) agitate cuttings on the low side of
the borehole to mix the cuttings in with the drilling mud which aids in hole
cleaning and cuttings mobilization.
- Cutting Structure: Field replacable PDC cutters allow fast tool turn around in
remote locations. Fixed cutters with no moving parts or bearings mean that there
is less risk in having a downhole failure.
- Optimized Stabilizer Blade Diameter and Length: The outer diameter of the
stabilizer blade and the distance between the uphole and downhole PDC cutters
was specifically chosen to match the dimensions of a packer element;
demonstrating that the reamer will go through the hole proves that there will be
less problems running the packer into the same hole.

The VersaStabe™ is a downhole, hydraulically actuated stabilizer. Designed for
use in a 2D directional drilling application to help control the inclination in
an extended reach or horizontal well, the VersaStabe™ can be utilized in a
conventional rotary bottom hole assembly, or positioned above or below a
steerable motor. The gauge diameter of the stabilizer is controlled remotely by
the pumps on surface.
The unique blade geometry of the VersaStabe™ makes it the only downhole
adjustable stabilizer that combines ease of sliding when run above a motor, with
improved cuttings transport when rotating.

The VersaStabe Jr.™ is a downhole, hydraulically actuated stabilizer. Designed
for use in a 2D directional drilling application to help control the inclination
in an extended reach or horizontal well, the VersaStabe Jr.™ can be utilized in
a conventional rotary bottom hole assembly, or positioned above or below a
steerable motor. The gauge diameter of the stabilizer is controlled remotely by
the pumps on surface.
The unique blade geometry of the VersaStabe Jr.™ makes it the only downhole
adjustable stabilizer that combines ease of sliding when run above a motor, with
improved cuttings transport when rotating. The VersaStabe Jr.™ is a shorter but
equally robust version of the VersaStabe™.

Designed for maximum performance and easy handling in horizontal or deviated
wells, the Cuttings Mobilizer™ is useful in reducing torque and drag problems by
removing cuttings resting on the low side of the wellbore, while strategic
placement of clusterite and stabilizer orientation are tailored and built into
the tool to assist in reaming operations. Reduction of the ECD (equivalent
circulating density) by keeping the wellbore clear of cuttings is one of the
major benefits of using the Cuttings Mobilizer™.
The Cuttings Mobilizer™ incorporates the following features:
- Short Overall Length: Designed for easy rig floor handling and more cost
effective manufacturing and transportation.
- Conventional Right-Hand Wrapped Stabilizer: Full 360° support minimizes wear to
the major diameter of the tool joint and rotor blades.
- Combination Left/Right-Hand Wrapped Stabilizer: Assists in hole cleaning and
moving cuttings and debris during back-reaming operations.
- Clusterite Covered Leading Edges: Aggressive stabilizer edges break up large
hole debris and cuttings but will not affect hole gauge.
- Cuttings Agitation: Rotor blades lift cuttings off of the low side of the
borehole and auger them into the mud flow.

Designed to provide easy release whenever disengagement becomes necessary, the
Safety Joint™ will transmit torque in the right-hand direction but will back-off
and disengage when required to release from stuck downhole string assemblies.
The Safety Joint™ can be designed to fit a full range of sizes, threaded
connections, lengths, etc. Arrival Oil Tools will work with the customer to meet
their exact requirements.

The Antenna Sub is placed in the bottom hole assembly to create an electrical
break in the drill string. This electrical break is used by Electromagnetic
Measurement While Drilling (EM MWD) equipment to initiate a subsurface signal
which conveys real time drilling parameters and information to the surface.
