This disclosure relates generally to equipment utilized and operations performed in conjunction with a subterranean well and, in an example described below, more particularly provides a well audit system and method.
A well audit can include inspections of components of a wellhead installation at a well location, as well as information (such as, maintenance history, status, photographs, etc.) useful for evaluating a condition or value of the wellhead installation. The components of a wellhead installation can include valves, actuators, chokes, pressure gauges, flowmeters, a tubing hanger, etc.
It will be appreciated that improvements are continually needed in the art of performing well audits and conveying well audit data to customers. The present specification provides such improvements, which can be used with a variety of different types of wellhead installations at multiple different well locations.

To maintain safe, efficient and effective operation of the wellhead installation 10, or to aid in a valuation of the wellhead installation (for example, for financing purposes), it can be useful to perform a well audit. The well audit can include inspection and testing of the components of the wellhead installation 10, as well as accumulation of pertinent data for the wellhead installation (such as, maintenance history, deferred maintenance, well type, wellhead and Christmas tree type, etc.).
It would also be useful to be able to provide this and other information to a customer in a manner that enables the customer to conveniently access the data and to quickly understand the results of the well audit. In addition to the well audit data, it would be helpful if the customer could access other relevant data pertaining to the wellhead installation 10, such as publicly available information or customer supplied information, so that all of the information is readily accessible at the same source.
In one example, the customer can access the wellhead installation information, including well audit data, customer supplied data and publicly available data, using a software application capable of receiving the information from an online database. The software application may be installed on a desktop computer, a notebook computer, a mobile device (such as a tablet or a cellular phone) or any other suitable computing device. The database may be stored on a server at the provider of the well audit service, or at a third party facility (e.g., “in the cloud”) or at any one or more locations.

Necessary or recommended remedial work for the displayed geographical area 28 can be shown in the display 26. For example, a list of remedial work can be displayed, and the list can be arranged in order of priority, with the most urgently needed remedial work appearing first in the list and routine remedial work (such as regularly scheduled maintenance) listed after the more urgently needed remedial work. In this manner, a customer can devote its resources most effectively and efficiently to the most urgently needed remedial work identified in the list.
If a user selects a particular one of the well locations 30a-c, the data stored in the database for that well location can be displayed in any of a variety of different formats (such as, in table form, as a graphic representation, in narrative form, etc.). As mentioned above, the data can include well audit data (e.g., specifying the functionality and condition of particular components of the wellhead installation), customer supplied data (e.g., the customer's identification of the well location, production data, etc.) and/or publicly available data (e.g., well data maintained by the American Petroleum Institute or a particular state). A prioritized list of remedial work for the selected well location 30a-c can also be displayed.
