General Well Information

- Objectives and scenarios (description or outline) - Flowpath (sketch) - Well trajectory of flowing well (survey) - Geological column (Lithology, plot or drawing) - Pore and fracture pressure plots - Temperature gradient (plot) - Surface layout (structures, pipelines ) - Drilling rig (for drilling the well as well as a candidate for drilling a relief well) - Drilling hazards (Shallow gas)

Comments: The information listed above will for most cases be available in the drilling program for the well. Copies of these pages will fulfill most of the data requirements listed herein. Use this information sheet as a checklist of required data. Please note that optional input will be estimated if not supplied. Fill in data in the unit you find most convenient. Required input is marked with yellow. Optional input is marked with gray

For heavy oils higher components is usually required to obtain a good estimate of fluid properties. The physical fluid data above is not required if the fluid composition is well defined, but can be used for quality control of the data. Please input if available.
