HIGHLIGHTS

Propane Markets In Northern California
In this study, we developed supply/demand balances for northern California on both annual and seasonal bases. Supply/demand analyses identified seasonal supply shortfalls and surpluses. Supply/demand analyses provided support for analysis of propane pricing trends in northern California. Refineries in California are the primary source of local propane production - especially in northern California. Refinery propane supplies often contain variable amounts of propylene. Stricter regulations on propane quality will have an impact on refinery propane production and will potentially require off spec propane supplies to be shipped to the Gulf Coast for processing in propane/propylene splitters. Hence we also evaluated propylene netbacks and values for the northern California market.

Long Term Outlook for Tennessee Propane Markets
We developed detailed analyses for propane end use demand in five states in the central Mid continent area. Our demand forecasts focused especially on trends in propane demand in Tennessee and Kentucky. We also developed estimates of the delivered costs of propane from various sources of supply.

Mont Belvieu NGL Storage Contract Survey
In this benchmarking study, we conducted a survey intended to determine the range of terms and conditions for NGL storage contracts in Mont Belvieu. Specific contract terms included in the survey were reservation costs, throughput fees, and storage charges. Respondents to the survey included NGL producers, NGL trading companies and ethylene producers.

Quality Trends in Mont Belvieu Natural Gasoline Markets
We conducted a survey of natural gasoline consumers in the Mont Belvieu natural gasoline service area. The intent of the survey was to identify and define variations in natural gasoline quality parameters for refiners and ethylene producers. In particular, our survey focused on variations in sensitivity to natural gasoline's sulfur content and to the specific species of sulfur in natural gasoline.

Mont Belvieu Purity Ethane Supply/Demand Trends
PWI prepared detailed forecasts for production and consumption of purity ethane in the Mont Belvieu area. The study included an evaluation of existing base load purity ethane consumers, swing purity ethane consumers and discretionary purity ethane consumers. The study provided the client with a detailed analysis of the outlook for purity ethane production from traditional fractionation suppliers and emerging new supply sources.

Long-term Outlook for Mont Belvieu NGL Fractionation Capacity
PWI prepared a detailed analysis and forecast of the outlook for NGL raw mix shipments into Mont Belvieu from traditional and emerging supply sources. The study also provided the client with a detailed assessment of changes in the composition of raw mix shipments to Mont Belvieu fractionation plants.
