Risks and Uncertainties [Abstract]
LIQUIDITY	LIQUIDITY In April 2016, Barnwell’s $1,000,000 Canadian-dollar revolving credit facility at Royal Bank of Canada was terminated. The termination was due to Barnwell's significant reduction in reserves as a result of the sale of its interests in oil and natural gas properties located in the Dunvegan and Belloy areas in September 2015 as well as a tightening credit market for oil and natural gas companies due to current low oil and natural gas prices and reductions in Royal Bank of Canada's forecast of oil and natural gas prices which decreased its valuation of the Company's remaining oil and natural gas assets pledged as security. In June 2016, Barnwell entered into a new agreement with Royal Bank of Canada for a revolving demand facility in the amount of $500,000 Canadian dollars, or U.S. $384,000 at the June 30, 2016 exchange rate, which is secured by a $500,000 Canadian dollar guaranteed investment certificate pledged to the Royal Bank of Canada (see Note 8). In April 2016, Kaupulehu 2007, LLLP ("Kaupulehu 2007") sold its remaining luxury residence for $5,700,000 and repaid the real estate loan in full from a portion of the proceeds. After the repayment of the real estate loan and distributions to minority interests, the Company netted approximately $1,500,000 in cash proceeds from the sale of the residence (see Notes 5 and 8). Additionally, in April 2016, KD Acquisition II, LLLP, which is part of the Kukio Resort land development partnerships in which the Company has an indirect ownership interest and an entity from which the Company has rights to receive percentage of sales payments, sold one ocean front parcel in Kaupulehu Increment II for $20,000,000. As a result of the sale, the Company received a percentage of sale payment in the amount of $1,600,000. The Kukio Resort land development partnerships also made a cash distribution in April 2016 to its partners of which Barnwell received $5,320,000, after distributing $40,000 to minority interests (see Note 6). At June 30, 2016, Barnwell had $17,433,000 in cash and cash equivalents and working capital totaled $17,107,000. Because of the combined impact of declines in oil and natural gas prices, declines in production due to oil and natural gas property sales, and increasing costs due to the age of Barnwell's properties, Barnwell's existing oil and natural gas assets are projected to have minimal cash flow from operations at current prices and production levels. As a result, the Company's existing cash will be needed to fund upcoming cash needs including asset retirement obligations, retirement plan funding, and ongoing operating and general and administrative expenses, such that some or potentially all of the cash may not be available for reinvestment. Barnwell will therefore be reliant upon future land investment segment proceeds from percentage of sales payments and any potential future cash distributions from the Kukio Resort land development partnerships, the timing of which is highly uncertain and out of our control, to fund operations and provide capital for reinvestment on a long-term basis.
