Oilfield and mining chemicals: Correlation
Prices it moves with, and why
Oilfield and mining chemicals include drilling fluid additives, fracturing chemicals, corrosion inhibitors and flotation reagents. Demand rises and falls with drilling and mining activity, which follows oil, gas and metal prices, and supply is often bundled with service contracts.
No public price Oilfield and mining chemicals has no public monthly price series: Sold under service contracts with operators; no public price index.What its price moves with
Barite is ground and added to drilling mud to control well pressure, and Andhra Pradesh in India is a major source. Barite demand rises with drilling activity, so rig counts drive both barite and mud chemical sales.
No public price for barite, so the link is explained in words only.High oil prices raise drilling and well work, lifting demand for oilfield chemicals, while price crashes, as in 2015 and 2020, cut it sharply. Oil also supplies many of the polymers and surfactants used.
Not enough overlapping price history to measure.Shale wells use large volumes of friction reducers, biocides, scale inhibitors and guar or synthetic gels. US shale activity, which responds quickly to oil and gas prices, is therefore the biggest swing factor in oilfield chemical demand.
Not enough overlapping price history to measure.Hydrochloric acid is pumped into wells to dissolve carbonate rock and clean perforations, and it is a large-volume fracking input. Supply from chlor-alkali plants is usually ample, so its price is a modest factor.
Not enough overlapping price history to measure.Corrosion inhibitors that protect pipes and wells are often built on fatty amines and imidazolines, and amines also treat sour gas. Amine costs therefore feed into the prices of these products.
Not enough overlapping price history to measure.Flotation reagents such as xanthates and frothers separate copper and other metal ores from rock. Higher copper prices encourage miners to process more and lower-grade ore, which raises demand for flotation and leaching chemicals.
Not enough overlapping price history to measure.How to read these numbers
Correlation of monthly changes (the number in the coloured pill) compares how much each price moved, month by month, since 2006 or the first month both series exist. It runs from −1 to +1: near +1 the two usually rise and fall in the same months, near 0 there is no link, and a negative number means they tend to move in opposite directions. Above 0.7 is strong, 0.4 to 0.7 moderate, 0.2 to 0.4 weak.
12-month changes compare year-on-year moves, which shows whether two prices share the same cycles even when the month-to-month noise differs.
Price function is a straight-line fit of the two prices on logarithmic scales: price ≈ k × (partner price)β. β is how much this price moves, in per cent, for a 1% move in the partner over the whole period, and R² is the share of the variation the fit explains. Two prices that both drift up with inflation can fit well without any real link, so read it together with the monthly correlation.
Lead or lag checks whether the monthly correlation is clearly higher when one price is shifted by 1 to 6 months.
Correlation is not cause. The reasons on each card explain the economic link; the numbers show how strongly it has shown up in prices. Proxy series are US producer price indexes or related prices and can blur the real link.
