block diagram of a system for implementing the present invention on a computer is illustrated the system includes a computing unit sometimes referred to as computing system which contains memory application programs a client interface and a processing unit the computing unit is only one example of a suitable computing environment and is not intended to suggest any limitation as to the scope of use or functionality of the invention the memory primarily stores the application programs which may also be described as program modules containing computer executable instructions executed by the computing unit for implementing the methods described herein and illustrated in fig2 a 3 the memory therefore includes a wellbore planning module which enables the methods illustrated and described in reference to fig2 a 3 and nexus u2122 although the computing unit is shown as having a generalized memory the computing unit typically includes a variety of computer readable media by way of example and not limitation computer readable media may comprise computer storage media and communication media the computing system memory may include computer storage media in the form of volatile and or nonvolatile memory such as a read only memory rom and random access memory ram a basic input output system bios containing the basic routines that help to transfer information between elements within the computing unit such as during start up is typically stored in rom the ram typically contains data and or program modules that are immediately accessible to and or presently being operated on by the processing unit by way.
