The WITS Implementation Guideline provides instructions and the format for transmitting real-time drilling parameters and information to joint interest partners.
The WELLSITE INFORMATION TRANSFER SPECIFICATION (WITS) is a communications format used for the transfer of a wide variety of wellsite data from one computer system to another. It is presented as a recommended format by which Operating and Service companies invdved in the Exploration and Production areas of the Petrdeum Industry may exchange data in either an online or batch transfer mode.
WITS is a multi-lwel format which offers an easily achieved entry point with increasingly flexible higher levels. At the lower levels, a f~ed format data stream is employed, while, at higher levels, a selfdefining customizable data stream is available.
A WITS data stream consists of discrete data records. Each data record type is generated independently of other data record types and each has a unique trigger variable and sampling interval. The rig activity usually determines which records are applicable at any given time such that only appropriate data is transmitted.
