Title:
SYSTEMS AND METHODS FOR IMPLEMENTING DIFFERENT MODES OF COMMUNICATION ON A COMMUNICATION LINE BETWEEN SURFACE AND DOWNHOLE EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2013/019417
Kind Code:
A3
Abstract:
Systems and methods for enabling communication using two different alternative protocols on a single communication line between remote tools and control equipment used in well operations. In one embodiment, a system includes control equipment, remote tools and a communication line coupled between the control equipment and the remote tools. Each remote tool detects mode control signals on the communication line and operates alternately in either a first mode or a second mode in response to detecting corresponding mode control signals. The first mode enables two-way communication of data on the communication line according to a first communications protocol. The second mode enables one-way communication of data on the communication line from the remote equipment to the control equipment according to a second protocol. The second protocol is different from the first protocol, and may be incompatible with the first protocol.
