SECTION 1: REAMING & BACK-REAMING

In Section 1 we look at the following :-

• Planning
• Organisation
• Parameters
• General Operations

SECTION 2: TRIPPING IN DEVIATED HOLE

In Section 2 we look at the following :-

• Planning
• Parameters
• General Operations

SECTION 3: HOLE CLEANING

Generally, Hole Cleaning is one of the commonest reasons for poor ROP (Rate of Penetration), Stuck Pipe and a variety of problems downhole.  Thus, in this section, we spend quite some time on the following :-

• Cuttings Transportation
• Mud Rheology
• Flow Rate
• Hole Geometry
• Mud Weight
• Cuttings Properties
• ROP
• Drillstring Rotation
• Rig-site Parameter Monitoring
• What the Shale Shakers Tell Us
• What Cavings Tell Us
• Hole Cleaning in Vertical / Near Vertical Wells
• Hole Cleaning in Deviated / Horizontal Wells
• Use of Hole Cleaning Charts

SECTION 4: MAKING CONNECTIONS

In this section we spend considerable time on :-

• Best Practices & Procedures

SECTION 5: MWD SURVEYS

In this section we spend considerable time on :-

• Best Practices & Procedures

SECTION 6: DRILLING PARAMETER TRENDS

Here we go through what changes in various parameters could mean, and how to interpret them, such as :-

• Torque, Drag, Over-pull, Standpipe Pressure, Changes in Cuttings Volume, Changes in ECD (Equivalent Circulating Density) etc.

SECTION 7: RUNNING CASING & LINERS

Successful Drilling isn’t just about drilling to Section T.D. We also need to case-off the drilled hole with casing / liner. In this section we look at :-

• Best Practices & Procedures

SECTION 8: LOGGING

We need to drill a hole which allows for the passage of logging tools to Section T.D. as well as their successful recovery.  Here we look at :-

• Best Practices & Procedures – Including Safety with Regard to Explosives
• Mud Conditioning
• Solids Control
• Differential Sticking Risk Mitigation

SECTION 9: CORING

Once we have reached Top Reservoir, many Operators choose to core for the vital data / information which core can deliver.  Here we look at :-

• Surge & Swab Mitigation
• Anti-Jamming
• Best Practices & Procedures

SECTION 10: LOST CIRCULATION

Lost circulation typically means problems, apart from high mud bills / costs. Here we look at:-

• Prevention
• What Should Be Done if Lost Circulation occurs
• Lost Circulation & Stuck Pipe Prevention
• Lost Circulation & Well Control

SECTION 11: PREVENTING DRILL STRING FAILURES

Drillstring Failures cost $millions particularly if the fish cannot be recovered and the well has to be side-tracked. Here we look at :-

• Care of Tubulars & Inspection
• BHA Connection Fatigue Prevention
• Drill pipe Fatigue Prevention

SECTION 12: SECONDARY FREEING PROCEDURES

Stuck Pipe Prevention and How to Get Free (Primary Actions) is covered in a separate E-Learning Package. Secondary Freeing Procedures are covered here, namely :-

• Pipe Release Agents; Procedure for spotting pills
• Acid
• Fresh Water Pills

• Assistant Drillers / Drillers / Toolpushers (especially Performance Toolpushers who are involved with “Turn-key” or “Performance” contracts) & Rig Managers;

• Offshore Drilling Engineers;

• Drilling Supervisors;

• Service personnel who wish to broaden their knowledge and understanding of Best Drilling Practices (e.g. Mud Engineers, Directional Drillers);

• Delegates who are in another industry or full-time education who envisage joining the Drilling Industry.
