TITLE:                REservoir analysis for WELLS DRILLED IN LAMINATED FORMATION

 

reservoir analysis FOR WELLS DRILLED IN LAMINATED FORMATION

BACKGROUND

[0001]                    Extracting fluid hydrocarbons from the subsurface involves the ability to estimate the properties of the subsurface formation from where the fluid hydrocarbons flow into the wells.  Reservoir production of fluid hydrocarbons from a wellbore depends on the ability of the reservoir formation surrounding the wellbore to allow the fluid hydrocarbons to flow into the wellbore. The ability of the reservoir formation to allow the fluid hydrocarbons to flow through the formation pore space is determined based on various field measurements.

SUMMARY

[0002]                    In general, in one aspect, embodiments are directed to a method to calculate a reservoir attribute value for a filtration area around a wellbore. A set of directional measurements are obtained for multiple measured depth intervals along the length of a wellbore. Based on the directional measurement set, the locations corresponding to a portion of the well exposed to a reservoir formation are filtered according to a quality criterion. The reservoir attribute value characterizing the reservoir formation in the selected locations is calculated based on the selected locations for each measured depth interval. The reservoir attribute value is presented.
