The present invention describes a unique method and apparatus for applying near-infrared spectroscopy to estimate weight percent of methane in crude oil from which one can then infer gas-oil ratio (GOR) of crude oils downhole in real time while collecting a fluid sample. The correlation equations provided by this invention use two wavelengths, one centered at 1670 and the other centered at 1682 nm. Both wavelengths are primarily sensitive to the methane peak absorption. To significantly improve the fit, non-spectroscopic parameters, such as temperature or pressure, can be included in the correlation equation. Also, this invention can be used to monitor sample cleanup by monitoring the increase in GOR associated with cleanup as a fluid being pumped from the formation transitions from mostly gas-free filtrate to mostly gas-containing crude oil.

An Orthogonal Frequency Division Multiplex (OFDM) transmitter (100) comprises a symbol generator (103) for generating a first OFDM symbol comprising user data and pilot data where the pilot data comprises a set of predetermined non-orthogonal pilot symbols. A weight generator (109) uses an amplitude estimator (107) for selecting a set of weights for the pilot data of the first OFDM symbol in response to a time domain amplitude variation characteristic of the first OFDM symbol. In particular, the peak to average power ratio may be determined. The set of weights are selected from a discrete alphabet of weights. A weight processor (113) determines a second OFDM symbol by weighting the pilot symbols by the set of weights. The second OFDM symbol is transmitted to a receiver without transmitting identification of the selected set of weights. The receiver may perform a blind detection of the applied weights and may compensate the received pilot symbols for the estimated weight.

A system and method for establishing a weight related risk profile using RFID technology is provided. While the cargo container is in transit, a RFID reader inside a cargo container polls the contents of the container by reading RFID data from each RFID tagged item and calculate the payload weight. When the truck transporting the cargo container passes a weigh station, or a high-speed scale embedded in the road, a payload weight is measured by a scale. A risk factor is assessed by comparing the estimated weight by the RFID reader with the measured weight by the scale. According to one aspect of the invention, the RFID based polling system has the ability to map the weight and location for each tagged item and estimate a container weight distribution. The estimated weight distribution is compared with the weight distribution measured by the scale to determine potential anomalies.
