  1. 9-Point Drilling Plan

  2. 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.

  3. 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

  4. Formation Tops • Surface formation • Marker beds used for correlation • Target formation(s)

  5. 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.

  6. 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.

  7. 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.

  8. 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.

  9. 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

  10. Testing, Logging & Coring • Describe general logging suite. • DSTs

  11. 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.

  12. 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.

  13. 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.
