IDEAS E-Learning Course

Welcome to IDEAS E-Learning Courses There are many advantages to E-Learning! Key features among them are: You can study in your own time and at your own pace You can repeat sections time and again until you understand things clearly There are no travel or hotel costs involved Interaction with the tutor is still possible, just as it is in physical classroom, through individual calls via Skype or e-mail / social media sites.

Course 2: Course Objective The objective of this course is to help people to understand the major components of the Drillstring starting with the whole range of drill bits available for the drilling of different types of rock through to the BHA (Bottom Hole Assembly) which includes stabilisers, NMDC s (Non-Magnetic Drill Collars), MWD (Measurement While Drilling) tools, LWD (Logging While Drilling) tools, PDM s (Mud Motors), Rotary Steerable Systems, Turbines, Drill Collars, Jars, HWDP and Drill Pipe. It cross-references the IADC Drilling Manual, API Standards & Recommended Practices, NACE, the Drilling Data Handbook, and Manufacturer s Information & General Industry Data. It also gives delegates further sources of information to pursue should they have a particular, more detailed interest. Who Should Do The Course The course has been written for several groups of personnel, for example: Operator personnel who are commencing a career offshore as Offshore Drilling Engineer or Trainee Drilling Supervisor; Drilling Contractor personnel who are on fast-track accelerated learning programs from young graduate or pump-man through to Assistant Driller; Drillers; Toolpushers or Performance Toolpushers who are involved with Turn-key or Performance contracts; Service personnel who wish to broaden their knowledge and understanding of Drilling Systems; Delegates who are in another industry or full-time education who envisage joining the Drilling Industry.

Section 1: Drilling Bit Types & Selection In Section 1 we look at, in a general sense, the types of drill bits available and their selection. Specifically we cover: The History & Background Behind Drill Bits Bit types & Classification (Roller Cone / Rock Bits; Fixed Cutter Bits) Key Drivers Behind Bit Selection (Geology, Rock Compressive Strength, Cost per Foot, Vibration, Drift, Overall Performance) Potential Problem Mitigation (Destructive / Premature Wear etc.) Section 4: Specialist Bits In Section 4 we look at Specialist / Specialised Bits, specifically for the following areas: Side-track Hard Rock Coring Anti-Whirl Coring Drill-Core Whipstock Jetting Turbine Eccentric Running Casing Whilst Drilling Casing Shoe Drill-Out Section 2: Roller Cone / Rock Bits Section 5: Bit Nozzle Sizing & Hydraulics In Section 2 we look at Roller Cone / Rock Bits in detail, specifically:- In Section 5 we simplify the rather complex subject area of Bit Nozzle Sizing & Hydraulics. We look at the following areas:- Type 1: Mill Tooth Cutter Bits:- Cutters, Cones, Gauge, Bearings, Nozzles, Classification, Potential Problems, Dull Bit Grading Bit Hydraulics Optimisation Specialist Hydraulics Presentations Determining Flow Rate Hole Cleaning Charts Determining TFA Total Flow Area Determining Nozzle Size Jet Impact Force Model And When to Use It Hydraulic Horsepower And When to Use It Mud Rheology Effects Type 2: Tungsten Carbide Insert Cutter Bits:Cutters, Cones, Gauge, Bearings, Nozzles, Classification, Potential Problems, Dull Bit Grading Section 3: Fixed Cutter Bits In Section 3 we look at Fixed Cutter Bits in detail, specifically: Type 1: PDC & TSD Cutter Bits:- Cutters, Blades, Junk Slot Area, Flow-by Area, Nozzles, Performance, Potential Problems, Dull Bit Grading Type 2: Natural Diamond Bits:- Diamonds, Blades, Gauge, Flow-by Area, Performance, Potential Problems, Turbine Usage, Cost Type 3: Impregnated Bits:- Cutters, Blades, gauge, Flow-by Area, Performance, Potential Problems, Turbine Usage, Cost Section 6: Drillstring Design In Section 6 we look at why Drillstrings are designed as they are. This is often a difficult area to understand in its entirety and so the section has been broken down into its constituent components so that the subject can be readily understood. We look at the following areas: Basic Components Listing Buoyancy & Neutral Point String Weight Number of DC s (Drill Collars) and HWDP (Heavy Weight Drill Pipe) required to give sufficient WOB (Weight to the Bit) Margin of Overpull Maximum Drill Pipe Length Before Tensile Failure Occurs Maximum Make-Up Connection Torque Bending Strength Ratio Bit Walk / Stabilisation / NMDC s (Non Magnetic Drill Collars) Jar Placement

Section 7: Drillstring Standards In Section 7 we look at the standards Drillstring steels are manufactured to and the standards to which Drillstring components should be maintained: Properties of OCTG (Oilfield Country Tubular Goods) Drillpipe Terminology Stress Buckling, Tension & Torsion Damage Stress Relief Stress Relief Groove, BoreBack Box Corrosion Poor Practices Offshore Preventing BHA / Drillstring Twist-offs, Washouts, Parted Strings Section 8: Drillstring Care & Inspection In Section 8 we look at API Standards & Specs as well as IADC Standards: API Standards for Pipe Inspections API 5DP; API Spec 7-1; API Spec 7-2 Care & Handling of Tubulars Safety First When Handling Tubulars Preparing to and Picking-up the BHA IADC Standards Reference to the IADC Manual Section 10: Drillstring Dynamics In Section 10 we look at how severe Drillstring Dynamics can cause Drillstring Failure and what can be done to avoid failure: Preventing Failures Shock & Vibration Axial, Lateral, Torsional, BHA Whirl, Stick-Slip & Eccentric Mitigating Shock & Vibration Shocks Whilst Drilling, Reaming, Pick-up Off Bottom Prior to Making a Connection Section 11: Directional BHA Design In Section 11 we spend considerable time looking at Directional Drilling Assemblies both their design and how they are utilized. Background Development Example Well Designs (Which Drive the BHA s Design) Deflection Techniques Whipstock, Rotary BHA s, Motors, Turbines Geo-Steering Horizontal Drilling Rotary Steerable BHA s Assemblies for Multilateral Drilling Section 9: Drill Pipe Body & Connections In Section 9 we look at the following: API Drill Pipe Double Shouldered Connections Landing String Intelli-pipe
