I. Safety Tailgate 4
I. Safety Tailgate 5
II. 2017 Recap – Spaghetti Style 6
III. Mechanical Systems - Hoisting Pneumatically controlled top drive Manual control added for safety and usability Raised rails 8 inches to allow for greater drilling depth 7
III. Mechanical Systems – Hoisting : Pneumatics Height of top drive controlled electronically by pneumatic converters or manual valve. 8
III. Mechanical Systems – Hoisting : Pneumatics Flowsheet Top Pneumatic Converter Pilot Top of air operated cylinder check Directional Bottom valve Pneumatic Converter Toggle Air supply Regulator valve Directional Bottom of Manual Pilot valve control operated air valve check cylinder 9
III. Mechanical Systems – Hoisting : Pneumatics - AirPilot Check Valves Valve prevents flow out of cylinder Air Signal unless air signal from opposite side of cylinder is provided Air cylinder holds position even when supply is disconnected Free flow is allowed when air is From Air supplied in automatic mode Supply When electrical signal is lost pneumatic converters reduce WOB to less than 5lbs From Air Cylinder 10
III. Mechanical Systems - Circulation Circulation system space efficiency increased New system working pressure is 400 psig 11
III. Mechanical Systems – Circulation Flowsheet 12
III. Mechanical Systems - Conduits and Carriers All cables and wires secured 3” ID conduit connects all boxes Rig mast can be laid down without crushing cables 13
III. Mechanical Systems – Hammer Motor Hammer motor location moved to rig Enables rig to be laid down without breaking connections Flow to swivel through cable carrier through flexible nylon tubing 14
III. Mechanical Systems - Instrumentation Pressure gauges added for: Compressed air supply Top air cylinder Bottom air cylinder Stand pipe 15
III. Mechanical Systems – Rig Supplies Connections for: 120 VAC, single phase 230 VAC 3-phase Quick connect 150 psig compressed air Quick connect city water hose 16
IV . Drill Pipe Connections – Phase I Inspiration for new connection: Last year compression fitting failure Increased pipe thickness – allows increased load capacity, requiring stronger connection Ideas discussed in Design report Raw threaded pipe (A) Threaded Pipe with Permanent Box (B) Square Kelly Connection (C) A B C 17
IV . Drill Pipe Connections – Phase II Raw Threaded Pipe Threaded Pipe with Permanent Box (Aluminum) Attempted to thread NPT connection on the pipe Used 1” 6061 Aluminum rod Pipe thickness not sufficient Machined 3/8” tapered NPT box at one end Machined 1” deep housing for 0.375” OD drillpipe Used Loctite Marine epoxy to bond the pipe & the connection Successfully tested the connection to a torque of 50 in-lb 18
IV . Drill Pipe Connections – Phase II Threaded Pipe with Permanent Pin (Brass) More efficient & cost effective solution Slimmer pre-threaded brass connections Machined 1” deep housing for 0.375” OD drillpipe Used Loctite Marine epoxy to bond the pipe & connection Used the same connection on both ends of the pipe 19
V . Remote System Control Remote system surveillance and control keeps people out of harm’s way Key Components: 2 Samsung 4K Monitors Off-site mission control center Security Camera System Two 4K IP cameras with 8X optical zoom One 4K Pan Tilt Zoom (PTZ) IP camera with 16X optical zoom Microphone Real time rig site audio Remote Desktop Connection Access to system controls from remote location 2-Way Audio Conversation 20
V . Remote System Control Remote Desktop Connection Benefits Allows remote user to have full control of the remote computer 2-Way Audio Stop work authority is given to offsite team members 21
V . Remote System Control 22
V . Remote System Control West PTZ North IP South IP RIG 23
V . Remote System Control The 8 channel Sibell receiver is housed on the rig in a waterproof electric box Power supply built into box 24

VII. Control System - Control Structure 2017 Look Back Driven by Dependencies Raise and lower functionality was dependent upon the pneumatic voltage pressure relationship No use of PID control Code structure was “spaghetti style” with zero notes or documentation Poor Program Structure No intuitive execution structure Minimal error feedback control Lack of tuned control structures Boolean logic 34
VII. Control System – Control Structure Sections Data Collection and Display Collected from Ni-DAQ analog inputs Data Processing and Filtering Backward weighted boxcar filters Auto Driller Dual layer PID control Analog Outputs Drives variable output actuators Digital Outputs Drives actuator relays 35
