As we were climbing out; we noticed the right engine oil pressure steadily decreasing; we cancelled the IFR with ATC; advised the passengers of what was happening and our intentions; came back and landed at [the departure airport]; wrote in the can and called [Maintenance].
A Cessna 402 pilot reported an oil system pressure anomaly during climb out; which resulted in an air return to the departure airport.
