This distribution reflects primarily the oil production for June 2018 and the gas production for May 2018. Preliminary production volumes are approximately 48,330 barrels of oil and 537,107 Mcf of gas. Preliminary prices are approximately $61.03 per barrel of oil and $2.71 per Mcf of gas.

The table below compares this month’s production and prices to the previous month’s:

Revenues are only posted and distributed when they are received. Most energy companies normally issue payment of royalties on or about the 25^th of every month, and depending on mail delivery, a varying amount of royalties are not received until after the revenue posting on the last business day of the month. The revenues received after that date will be posted within 30 days of receipt.

Due to the timing of the end of the month of August, approximately $2,618,000 of revenue received will be posted in the following month of September in addition to normal receipts during September. Since the close of business in August and prior to this press release, approximately $1,208,000 in revenue has been received.

The January 1, 2018 Reserve Summary is available on the Sabine website at http://www.sbr-sabine.com/.
