Abstract

Disclosed is a system and method for directing data representing well operations (drilling and producing) through the Internet or similar wide area network. The instant invention comprises a system and method of installing sensors at the well to provide technical information to remotely-located Internet users who provide services to the well owner. The service providers may be observers, who may then advise the well owners and operators as to actions to take to increase or optimize well performance. Service providers may also be data storage companies, who clean and store the data from the well. Service providers may then be paid from a portion of the well revenues or a portion of the incrementally-increased revenues.
