These questions may require students to elaborate on a particular legal principle or case, exploring various perspectives or discussing its implications in practice.2.3. Skills Tested in Law ExamsLegal Analysis
and Application: Law exams test a student’s ability to identify relevant legal issues, apply appropriate laws and precedents, and reach conclusions based on the facts presented. This requires a deep
understanding of case law and statutory law.Critical
What precautions must be used 1. Reduce Air Pressure
when sand seams are encountered in 2. Use of Foam or Polymers
air rotary drilling in unconsolidated 3. Monitor Cuttings
formation? 4. Casing Advancement
5. Slow Drilling Rate
How are samples obtained in air Continuous Sampling of Cuttings:
rotary drilling in unconsolidated Split-Spoon Sampling
formations? Drilling Fluids/Polymers
Hole cleaning and penetration rates Air Pressure and Volume
will vary with air rotary. What factors Formation Type
affect cleaning and penetration? Bit Type and Condition
Drilling Fluid/Injection
Drill Pipe Size and Depth
Cutting Size and Volume
, Why is information concerning the Permeability of the Formation
geology important in proper Stability of the Formation
grouting of unconsolidated Formation Pressure
formations? Groundwater Flow
Formation Composition.
When would you gravel pack a well? When the formation is unconsolidated, to prevent
sand or fine material from entering the well, and to
enhance water flow by stabilizing the borehole
What formations are best to use a clay, sand, or shale.
soft tri-cone bit?
What functions must a drill pipe Transmit torque
perform to drill unconsolidated circulate drilling fluid/air
formations? support drill string weight
maintain borehole integrity
When would you use heavy drill to add weight on the bit, stabilize the drill string,
collars? and prevent buckling in deep or hard formations.
Explain how chip catchers can aid in help collect cuttings for accurate formation
formation logging? logging by preventing loss of samples during
drilling, ensuring representative data.
How does bit design vary with varies by formation hardness, with softer
geology? formations needing wider teeth and harder
formations requiring tougher, more durable
materials.
Heavy steel casing would best be best used in the air rotary process for stabilizing
used in what rotary process? unconsolidated or collapsing formations.
These questions may require students to elaborate on a particular legal principle or case, exploring various perspectives or discussing its implications in practice.2.3. Skills Tested in Law

in rotary drilling? spear
fishing magnets
junk baskets
Regular maintenance of the rotary Lubrication, checking for leaks, inspecting
swivel consists of what? bearings, and replacing worn seals.
What methods are used to clean the Airflow, foam injection, and polymer use.
hole of cuttings in air rotary drilling
in unconsolidated formations?
How does air pressure change as the must increase as the hole deepens to maintain
hole deepens? effective cuttings removal.
What are the advantages and Advantages: Faster drilling, efficient cuttings
disadvantages of high pressure air removal.
rotary drilling in unconsolidated Disadvantages: Risk of formation collapse, loss of
formations? circulation, potential for blowouts. These questions may require
