In our evolving world of oil and gas production, more data is being requested more often, Old 9,600 baud analog style radios can't keep up with the new demands. Almost continuous polling and higher transmission speeds are requiring communications systems to evolve from a single network solution into multiple networks, each of these networks provides layers of communication. To create these multiple layers requires multiple products. Layer #1 is wireless IO between wellhead instrumentation and the EFM or controller. Layer #2 is communication from the controller or EFM to a larger backbone communication system that can cover the entire geographic area of the field. Layer #3 is a backhaul communication system that can take the data from the field to anywhere in the world where the data may be needed. These layers must have common interfaces and the ability to pass data seamlessly between them. Source

There are several technology options in the marketplace for the oil and gas industry in particular, that offer communication solutions for both exploration/production and midstream pipeline monitoring. The oil and gas industry is unusual because of the consistently present explosive gases that often create a hazardous environment. By using a certified C1D1 wireless I/O solution an operator or producer can receive real-time updates from the pipeline and production facilities that could enable them to act before an incident occurs. A discussion covers the Class 1 Division 1 (C1D1) UL listing; options in the market place in selecting a sensor and hardwire solution; the wireless I/O and its applications; and choosing a wireless communications provider.

As oil and gas companies work toward greater automation and e-business solutions, the challenges of getting real-time, reliable data from remote locations continues to be one of the greatest problems. Currently, there are many fine choices in electronic flow measurement and remote terminal unit equipment available. There are also many fine bug-free software programs to archive, audit, and display the collected data. A few years ago, a new radio medium became available. This system operates on a shared frequency and is called spread spectrum. This new technology offers many advantages and new versatility to SCADA operators. There are two types of spread spectrum radios in use in the industry, i.e., direct sequence and frequency hopping. Both technologies employ digital packet data. A significant step in choosing a radio provider is finding a company that will assist in the design, installation, and implementation of a radio network. About 80% of communications problems can be traced to poor or no design. The first step to a system design is to get the GPS reading to your provider. The second step is to have every radio link plotted on a radio path study software program. One of the qualities of spread spectrum radios that may oil and gas companies have found endearing is the ability to tail-end spread spectrum onto other communication mediums. The two most common tail-end additions are to add spread spectrum to licensed radios and to combine spread spectrum to cellular digital packet data modems. Source

New technologies introduced over the past several years have stream lined the processes for cathodic protection (CP) monitoring. Previously, a time-consuming manual method was the only option. Now, pipeline operators have a handful of options. Automated remote monitoring in particular has increased in popularity as a viable tool for pipeline, energy, and utility operators. Many of these technologies can send data directly to a computer or smart phone from a remote location. The large range of communication technologies available for remote monitoring applications can be daunting when it is time to make a decision. Before selecting any sort of communications network, operators must be familiar with the options and their capabilities. Spread spectrum, licensed wireless data radios that collect mission-critical data, in particular, have become a strong option for automated monitoring. Some of their most compelling features include the benefit of real-time data and the ability to be used in the most remote locations without monthly and recurring fees. Source


A broadband superheterodyne receiver. Embodiments include an input for receiving an RF signal including an RF data signal at a carrier frequency. An RF mixer coupled to the input shifts the RF data signal from the carrier frequency to an IF frequency. An IF band pass filter coupled to the mixer has a pass band, and band pass filters the signal near the IF frequency. A spectrum analyzer provides information representative of the spectral characteristics of the received RF signal around the RF data signal at the carrier frequency. An IF controller is coupled to the RF mixer and to the spectrum analyzer. The IF controller: (1) determines an interference-mitigating IF frequency within the pass band of the band pass filter that will result in attenuation of undesired portions of the RF signal, and (2) controls the RF mixer to shift the RF data signal to the interference-mitigating IF frequency.
