Who Should Attend

This course will benefit geologists who are involved in looking for permeability barriers and subtle traps missed by others in well-drilled basins or those looking for potential stratigraphic traps in unfamiliar overseas basins. Also aids those struggling with subtle correlations of sands with similar log signature. No prior knowledge of the subject is necessary.

Objectives

By the end of the course, participants should be able to accomplish the following:

• Screen sources of field pressure data to select valid reliable stable Formation pressures to plot
• Use pressure vs. depth plots to correlate reservoirs (Are zones separate or continuous?)
• Predict depth of gas /oil/water contacts downdip from wells of interest or discovery wells
• Make reservoir continuity maps based on the Pressure information to show areal extent of traps & reveal the areas of best permeability from the pressure contour spacing
• Avoid less prospective areas which may be flushed by updip water flow or are depleted by close-by production
• Reveal more favorable areas where downdip flow water preserves oil pools with weak barriers
• Assess trap holding capacities of seals particularly Unconformity traps by knowing pressures of the reservoirs above & below subcrops edge
• Identify “Central Basin Gas” type areas of continuous gas phase continuity- resource plays from the pressure signature. These are in essence also stratigraphic traps.

Content

The format of the course is such that students learn by hands on class projects in a step by step fashion where they start with screening raw data & finish off with completed Plots & maps. In all cases students are given the limited data prior to discovery of a pool & then “discover” the pool with interpreted plots & maps. They then have to assess how big the find is from the discovery well pressure data.

Two projects are in conventional reservoirs (including the Williston Basin) the other is in a tight gas type resource play where many operators had wrongly interpreted the data as showing 5 small isolated gas pools but the plots reveal one giant gas field with one TCf of reserves.
