Abstract
Apparatus and methods for webserver-based well instrumentation, logging, monitoring and control provide convenience and economy in well site and off-site operations. In a described embodiment, a well tool includes a webserver connected to a sensor and an actuator of the tool. In response to a condition sensed by the sensor, a person utilizing a network to access a web page supported by the webserver at a remote location may operate the actuator to control operation of the well tool.
