Abstract

The need to create a real-time experience was crucial to remotely show a seismic acquisition system at the recorder, located 35 km away from an event venue built in the desert. This was achieved through live audiovisual communication for 200 participants. Major challenges faced were: the event location was outside the scope of conventional IT support; the large number of participants; 30-day time constraint; conducting a feasibility study in the field; conduct a continuous test until a proposed in-house solution was functional; and otherwise integrate with an alternative third-party-produced backup solution.

The proposed solution describes how a packet-switched network and H.323 signaling protocol operating on an IP-based network was used for videoconferencing (VC) between two remote locations. The two main components of the signaling protocol were the registration admission status that controls the entire video network, used between the gatekeeper and the VC unit, and the Q.931 responsible for establishing and cancelling the connection between the VC units. The remote screen- sharing tool for broadcasting the seismic acquisition system uses the secure socket layer (SSL) for communications security. The key exchange protocol used was remote access service, while the data encryption is AES256-SHA used by means of the web browser that supports it. A follow-up with the supplier was made to double the current bandwidth to prevent a drop in the network performance.

The successful outcome of the event demonstrated how IT can contribute outside their normal scope of work by providing event design and coordination, and can succeed in helping participants make informed decisions by facilitating a real-time seismic experience that saved the business USD 30K.

This paper depicts the high value of IT by delivering business solutions.
