Chemical plant cost indexes are dimensionless numbers employed to updating capital cost required to erect a chemical plant from a past date to a later time, following changes in the value of money due to inflation and deflation. Since, at any given time, the number of chemical plants is insufficient to use in a preliminary or predesign estimate, cost indexes are handy for a series of ...
Cost data of 412 pipelines recorded between 1992 and 2008 in the Oil and Gas Journal are collected and adjusted to 2008 dollars with the chemical engineering plant cost index (CEPCI).
assured at great cost. The mining sector also faces a shortage of skilled workers that is projected to become more severe in the future. Finally, the impact of mining operations on all aspects of the environment is a key issue and must be addressed as an integral part of all mining operations.

Upstream Operating Costs Index (UOCI) The UOCI measures cost changes in the oil and gas field operations arena. It is similar to the consumer price index (CPI) in that it provides a clear, transparent benchmark tool for tracking and forecasting a complex and dynamic environment. The UOCI is a work product of the Upstream Operating Costs Service.
For example, in a hard rock mining situation (eg, copper or gold), mining engineers often control costs by reducing blasting 2. This ends up increasing overall cost of the operations because poorly fragmented material is delivered to the plant, dramatically increasing milling costs and, more importantly, decreasing throughput.
