A set of logs run on a well usually mean different things to different people . In this blog , we examine the questions asked –and/or answers sought by variety of petroleum people .
The Geophysicist :
- Are the tops where you predicted ?
- Are the potential zones porous as you have assumed from seismic data ?
- What does a synthetic seismic section show ?
The Geologist :
- What depths are the formation tops ?
- Is the environment suitable for accumulation of hydrocarbons?
- Is there evidence of hydrocarbons in this well ?
- What type of hydrocarbons ?
- Are hydrocarbons present in commercial quantities ?
- How a well is it ?
- What are the reserves ?
- Could the formation be commercial in an offset well ?
The Drilling Engineer :
- What is the hole volume for cementing ?
- Are there any key seats of severe doglegs in the well ,
- Where can you get a good packer seat for testing ?
- Where is the best place to set a whipstock ?

The Reservoir Engineer :
- How thick is the pay zone ?
- How homogeneous is the section ?
- What is the volume of hydrocarbons per cubic meter ?
- Will the well pay-out?
- How long will it take?
The Production Engineer :
- Where should the well be completed (in what zone(s))?
- What kind of production rate can be expected ?
- Will there be any water production ?
- How should the well be completed ?
- Is the potential pay zone hydraulically isolated ?
- Will the well require any stimulation ?
- What kind of stimulation would be best ?
