wellActivity.com provides an online searching service of a real time updated well permits database of the United States. The service allows users to search well permits by date, areas and business names, and provides maps and driving directions to the found wells. This service gives many businesses serving the petroleum industry the instant access of the information of the newly issued well permits. However, there is a challenge faced by ZDM: all wells are in the rural areas where there are no addresses; how can people identify and locate these individual wells? "We originally planned to use longitude/latitude coordinates to represent the locations of wells, but the long character strings of these coordinates are really difficult for people to remember and communicate. The variations in representing longitude and latitude add even more complexities in dealing with the user input," said Mr. Don Cayce - the Chief Technical Officer of ZDM, "The Universal Address System seems to provide a perfect solution to this problem. It makes the long geographic coordinates represented by codes as simple as postal codes. An eight character Universal Address can uniquely specify the location of any well in the world without the needs of country name, state name, and county name." As the licensing agreement is signed, ZDM will use Universal Addresses as well identifiers in its database and as addresses for users to specify locations for driving directions. ZDM will also implement the capability for users to use Natural Area Codes (NAC) to specify areas for location based searches.

NAC Technology introduces a highly efficient universal representation called Natural Area Code to unify the representations of all area codes, geographic coordinates, map grids, street addresses, postal codes and property identifiers of the world. An eight or ten character NAC (also called Universal Address) can uniquely specify every building, house, bus stop, parking meter, fire hydrant, street light, sewage exit, etc anywhere in the world. A six character NAC can specify every square kilometre area on the earth. A four character NAC can be used to represent every city size area in the world. Using NAC instead of street addresses and place names to specify locations and areas in all location applications can reduce 80% of input characters, avoid difficulties in inputting addresses with foreign characters, eliminate errors from address databases and extend geographic coverage to all locations and areas no matter whether there are addresses or not. Universal Addresses can also be directly displayed on GPS receivers, pinpointed on all maps , and can even be used as Global Postal Codes to sort all mail from the world level to final mailboxes automatically. They will be shown on all watches - time-space watches and become as important as accurate time for all human activities.

"It's another breakthrough for NAC Technology," said Xinhang Shen, President of NAC Geographic Products Inc., "and the first time that NAC Technology is to be implemented in petroleum industry. Enhanced with NAC Technology, ZDM's wellActivity.com will immediately become the leading information system in oil industry of the world with its universal interface, high efficiency, high reliability and complete coverage. It is another milestone for NAC Technology to be widely deployed in the commercial products and services."
