Remote communications for exploration and production
Exploration and drilling are highly challenging tasks and need reliable, always available communications, often outside the reach of terrestrial communication networks. Volker Jarsch reports.

ommunication via satellite is the way to reach the off-shore and remote sites. Engineers and supporting staff require good voice quality and stable data throughput amongst the relevant sites.
Te drilling process depends on real-time direct connectivity with the customer’s engineering lab. Information gained at the drilling site needs to be transmitted without delay to the lab for analysis by the geologists and their supporting tools. In turn, the drilling process is controlled in real-time by control-info created at the lab. Surveillance of remote installations, pipeline sections and video reporting of relevant events require broadband transmissions from one or more sites to the company headquarters, and also to the headquarters in the region where the drilling and the production take place. Current mainstream satcom solutions fall short in fulfilling these evolving requirements and force companies to compromise on functionalities that challenge technical boundaries. Point-to-point connections with dedicated satellite capacity meet

the requirement for single-hop connectivity, but are constrained in the fixed bandwidth. Tey are expensive, because not all capacity of each single link is used all the time and parallel connections between multiple sites require cumulative space capacity, ie they are for oil and gas applications insufficient and yet unnecessarily expensive. Te typically offered star networks with one central site at a service provider’s main site allow
