Method and apparatus for interactive curved surface borehole interpretation and visualization
First Claim
1. A method for projecting borehole data obtained from a scan of a borehole wall onto a display surface using a video projector connected to a computer wherein said computer graphic image is projected onto a concave display surface and wherein said computer graphic image is derived from a set of borehole data, said method comprising:
- a) storing a set of 2D borehole data in a memory of said computer;
b) creating a mathematical model for said concave display surface in said memory, wherein said mathematical model at least partially intersects said set of 2D borehole data in the memory;
c) extracting borehole data from said set of 2D borehole data intersecting said mathematical model in said memory to provide an extracted data set; and
d) projecting said extracted data set onto said concave display surface to produce a computer graphic image of spatially correct borehole data.

Abstract
An enlarged computer graphic image of borehole data is displayed on a concave three-dimensional surface, preferably a semi-cylindrical shape. Thus providing an enlarged image of a borehole surface where the data is spatially correct in three-dimensions, and which increases the ease with which interpreters can locate geological features such as surfaces, faults, and fractures.
