Presentation Goals

To Describe a Drilling Plan That…

  • Is in compliance with Order #1.
  • Clearly and thoroughly describes the proposal and anticipated conditions.
  • Provides the necessary information, in a clear format, that enables an expeditious review.
drilling plan components overview
Drilling Plan ComponentsOverview
  • Formation Tops
  • Depth to Oil, Gas, Water & Minerals
  • Pressure Control
  • Casing
  • Cement
  • Circulating Medium
  • Testing, Coring, Logging
  • Pressures, Temperatures, LCZs, H2S
  • Other aspects of the proposal
formation tops
Formation Tops
  • Surface formation
  • Marker beds used for correlation
  • Target formation(s)
zones containing oil gas water and other minerals
Zones containing oil, gas, water and other minerals
  • Distinguish between target zones and zones that may contain hydrocarbons.
  • Identify salt water zones also, as they would affect drilling conditions.
  • Plans for protecting those resources.
blow out prevention
Blow-Out Prevention
  • Size, rating, configuration & testing.
  • Schematic diagrams, “a picture is worth 1000 words.”
  • Describe any ancillary equipment such as, rotating head, remote kill line, mud-gas separator, etc. that would be used.
casing design
Casing Design
  • Size, weight, grade, thread & coupling, depth and condition.
  • Include the design criteria, loading assumptions and safety factors used.
  • Non-standard casing; include published specifications.
  • If an alternate casing is being considered, include all specifications.
  • Identify liner top and lap length.
  • Describe any unusual design conditions.
cementing
Cementing
  • Amount and type of cement, including additives for each slurry.
  • Density & yield.
  • Stage cementing--DV tool placement.
  • Top-of-cement as designed, and excess volume.
circulating medium
Circulating Medium
  • Type & characteristics of mud for each section of hole, and description of standby mud.
  • Air Drilling
    • Blooie line length
    • Dust suppression
    • Gas ignition
    • Compression equipment size & location
testing logging coring
Testing, Logging & Coring
  • Describe general logging suite.
  • DSTs
anticipated pressures abnormal hazardous drilling conditions
Anticipated pressures, abnormal/ hazardous drilling conditions
  • Anticipated BHP. If it does not correspond with mud weight, explain.
  • Identify up-hole high pressure zones, lost circulation zones, etc.
  • If H2S is anticipated, Order #6 applies.
other facets of the proposal
Other facets of the proposal
  • Directional & Horizontal wells: include design, plan view, vertical section, measured and true vertical depths.
  • If the completion is deviated, include location of the top and bottom of the target zone relative to lease and section lines.
summary and final thoughts
Summaryand Final Thoughts
  • A complete and thorough drilling plan improves processing efficiency.
  • Any aspect of the drilling plan that is unusual should be explained.
  • APDs are transferable.
  • Amendments and modifications to the drilling plan.
