Rig Specifications
Mast Unit
The T500XD is a trailer mounted portable land rig designed to API 4F, 7K
and 8C standards. Dual MTU V2000 diesel engines provide power to the
hydraulic system for drilling operations.
The trailer mounted Telemast
system consists of fewer loads and offers rapid set-up and deployment.
Automated pipe handling, slip actuation and breakout systems set this
machine apart from conventional oilfield equipment. Our Half-Triple concept
is designed to utilize Range 3 drill pipe for increased drilling efficiency and
quick trip times.
The mast unit is mounted on a 4 axle trailer with tandem tag axle and
includes hydraulic components necessary to transmit power to the feed,
rotation and auxiliary functions. Quick coupled hoses transmit the hydraulic
supply from the Power Unit to the rig's Mast Unit.
Telescoping construction permits long head travel and working height, yet
short overall length in the transport position. Equipped with a 30" (762 mm)
cylinder operated slide, the mast is free-standing, all pullback loads are
directed into the floor, not the rig frame. The mast is anchored to the rig floor
via locking pins.
Feed System - The top head is raised and lowered by hydraulic traverse
cylinders through 2-7/16" (63 mm) OD wire rope (370 Tons Nominal Breaking
Strength per strand) and 77" PD Nylatron sheaves. As the tophead is raised,
the inner mast section extends by a ratio of 1:2 until it reaches its fully
extended position at 56' of head travel.

Mini Lube System - A multi-point systemis provided to simplify librication
of drill components. Provides centralized grease fitting locations for top head,
crown, jib boom.
Top Drive Details
The hydraulic top drive is powered by a radial piston motor and is mounted to
a tilting slabback to facilitate pipe handling functions via the LoadSafe. A
floating sub is provided to extend the life of threads by removing feed cylinder
and pipe weight forces from threads while making and breaking tool joints.
Casing lifting eyes are slabback mounted to work in conjunction with
commercially available elevator links (not included). The top drive includes a
rotation lock and rebound prevention circuitry for use when directional
drilling. An in-line mud saver valve is mounted in the top drive spindle.
Connection at top drive swivel is 3".

Main Winch - A hydraulically powered winch is mounted to the side of the
mast for utility lifting operations. The winch is a planetary type with
overrunning clutch, hydraulic brake valve and spring applied hydraulic
release brake. The winch operates independently of the other drilling
functions. Winch is reeved over a hydraulic jib boom which centers the line
over the center of the borehole.

Hydraulic System
Each engine is directly coupled to a pump drive gearbox
to power its hydraulic power system. To obtain full system performance, both
engines must be operated at 1800 rpm. However, when drilling conditions
permit, one engine can be operated for fuel savings and to provide
maintenance capability without stopping the drilling process. Each engine
has an identical hydraulic system so either unit can be run with the same
performance. The hydraulic system includes a 1000 gallon tank with full
return oil filtrations. All pumps are protected by suction line strainers and all
hydraulic circuits are protected by relief valves and oil cooler system.
Walkway platforms are provided for access to hydraulic tank during
maintenance operations.

Rig Performance Parameters
TBD prior to order acceptance.
Start-up and Initial Testing
Drill rig components will be built in West Chester, PA, USA for deployment to
Alpha Hunter Drilling LLC rig-up yard for integration, set-up and start-up
testing. Schramm will be responsible for functional and initial testing in West
Chester and start-up testing of the rig components listed in the Scope of
Supply at the Alpha Hunter yard in PA, WV or OH (TBD) once the drilling
package is assembled. Alpha Hunter Drilling LLC will be responsible for the
components it supplies.
Horizontal Well Testing
Schramm service technicians and engineers will be on-site during the drilling
of two (2) horizontal wells by Alpha Hunter Drilling personnel in the PA, WV
or OH location of their choosing. Alpha Hunter Drilling LLC will be
responsible for the rig operation.
Training and Field Service Support
Schramm will train Alpha Hunter Drilling crews in the operation and
maintenance of the drilling rig and will be either on-site or available on a 24/7
basis during the first 6 months after delivery.
Other Considerations
It is understood that the T500XD is a prototype drilling rig, and as such, may
require additional testing, extra time for set-up, trouble shooting and field
modifications not typically associated with a production model. Alpha Hunter
Drilling will cooperate and coordinate with Schramm personnel to facilitate
testing and repairs as may be required. Schramm personnel can have
access to the rig when and where appropriate and may bring visitors to either
aid in the repairs or maintenance, or for the purpose of demonstration to
potential customers. Prototype specifications are subject to change and will
be mutually agreed to prior to implementation and may affect final price or
delivery.
