The Huabei petroleum complex
• Oil and gas exploration in Huabei initiated in 1955. The Huabei complex includes 27 HC fields– On July 4, 1975, the Renqiu field – one of the
largest carbonate oilfield in China was discovered. In 1978, it reached its peak production, the well Ren-4 producing at a yield of thousand ton per day
– A production of ten million ton oil per year had been maintained for ten years till 1986.
• A total of more than 1,900 Km pipelines have been constructed for oil transportation to refineries in Shijiazhuang, Changzhou and Yanshan as well as for natural gas delivery to Beijing.

ArcMap GIS-based least-cost pathway model (model 2)
– Based on GIS cost grids.
A model was implemented to first calculate the least-cost pathway between sources and sinks depending on the transport cost, and then take into account sink capacity.

Spatial Analyst Tools - Distance
• Cost Allocation: calculates for each cell its nearest source based on the least accumulative cost over a cost surface.
• Cost Back Link: defines the neighbour that is the next cell on the least accumulative cost path to the nearest source
• Cost Distance: calculates the least accumulative cost distance for each cell to the nearest source over a cost surface
• Cost Path: calculates the least-cost path from a source to a destination
