“Significant reductions in exploration and development spending in 2015–16 led to less drilling, which reduced oil production in the fourth quarter of 2016, offsetting increased revenue that came from higher prices,” EIA said.
Cash from operations lags capex for these companies because they invest to develop reserves that will increase oil production and cash flow in the future.
Hedging
These companies have taken advantage of the recent bump in crude prices to hedge their investment in production into the future.
A measure for the amount of future production oil companies have hedged is the number of short positions into these markets. These short positions consist of futures and option contracts held by producers and merchants.
Producers have begun using them more since crude oil prices rose above $50/bbl in fourth-quarter 2016. In mid-February, the number of short positions in US-based futures and options reached 756,000 contracts, close to the 10-year high of 802,000 contracts.
