It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits are not generally reported as cash and cash equivalents.", "label": "Cash and Cash Equivalents, at Carrying Value, Including Discontinued Operations", "units": { "USD": [ { "accn": "0000077877-15-000012", "end": "2011-12-31", "filed": "2015-02-19", "form": "10-K", "fp": "FY", "frame": "CY2011Q4I", "fy": 2013, "val": 8238000 }, { "accn": "0000077877-15-000012", "end": "2012-12-31", "filed": "2015-02-19", "form": "10-K", "fp": "FY", "fy": 2013, "val": 2457000 }, { "accn": "0000077877-16-000070", "end": "2012-12-31", "filed": "2016-02-22", "form": "10-K", "fp": "FY", "frame": "CY2012Q4I", "fy": 2015, "val": 2457000 }, { "accn": "0000077877-15-000012", "end": "2013-12-31", "filed": "2015-02-19", "form": "10-K", "fp": "FY", "fy": 2013, "val": 193243000 }, { "accn": "0000077877-16-000070", "end": "2013-12-31", "filed": "2016-02-22", "form": "10-K", "fp": "FY", "fy": 2015, "val": 193243000 }, { "accn": "0000077877-17-000006", "end": "2013-12-31", "filed": "2017-02-28", "form": "10-K", "fp": "FY", "frame": "CY2013Q4I", "fy": 2016, "val": 193243000 }, { "accn": "0000077877-15-000012", "end": "2014-12-31", "filed": "2015-02-19", "form": "10-K", "fp": "FY", "fy": 2013, "val": 16066000 }, { "accn": "0000077877-16-000070", "end": "2014-12-31", "filed": "2016-02-22", "form": "10-K", "fp": "FY", "fy": 2015, "val": 16066000 }, { "accn": "0000077877-17-000006", "end": "2014-12-31", "filed": "2017-02-28", "form": "10-K", "fp": "FY", "fy": 2016, "val": 16066000 }, { "accn": "0000077877-18-000008", "end": "2014-12-31", "filed": "2018-02-27", "form": "10-K", "fp": "FY", "fy": 2017, "val": 16066000 }, { "accn": "0000077877-18-000016", "end": "2014-12-31", "filed": "2018-05-01", "form": "10-K/A", "fp": "FY", "frame": "CY2014Q4I", "fy": 2017, "val": 16066000 }, { "accn": "0000077877-16-000070", "end": "2015-12-31", "filed": "2016-02-22", "form": "10-K", "fp": "FY", "fy": 2015, "val": 850000 }, { "accn": "0000077877-17-000006", "end": "2015-12-31", "filed": "2017-02-28", "form": "10-K", "fp": "FY", "fy": 2016, "val": 850000 }, { "accn": "0000077877-18-000008", "end": "2015-12-31", "filed": "2018-02-27", "form": "10-K", "fp": "FY", "fy": 2017, "val": 850000 }, { "accn": "0000077877-18-000016", "end": "2015-12-31", "filed": "2018-05-01", "form": "10-K/A", "fp": "FY", "frame": "CY2015Q4I", "fy": 2017, "val": 850000 }, { "accn": "0000077877-17-000006", "end": "2016-12-31", "filed": "2017-02-28", "form": "10-K", "fp": "FY", "fy": 2016, "val": 244100000 }, { "accn": "0000077877-18-000008", "end": "2016-12-31", "filed": "2018-02-27", "form": "10-K", "fp": "FY", "fy": 2017, "val": 244100000 }, { "accn": "0000077877-18-000016", "end": "2016-12-31", "filed": "2018-05-01", "form": "10-K/A", "fp": "FY", "frame": "CY2016Q4I", "fy": 2017, "val": 244100000 }, { "accn": "0000077877-18-000008", "end": "2017-12-31", "filed": "2018-02-27", "form": "10-K", "fp": "FY", "fy": 2017, "val": 180675000 }, { "accn": "0000077877-18-000016", "end": "2017-12-31", "filed": "2018-05-01", "form": "10-K/A", "fp": "FY", "frame": "CY2017Q4I", "fy": 2017, "val": 180675000 } ] } }, "CashAndCashEquivalentsPeriodIncreaseDecrease": { "description": "Amount of increase (decrease) in cash and cash equivalents.

Certificates of deposit generally restrict holders from withdrawing funds on demand without the incurrence of penalties. Generally, only certificates of deposit with original maturities of three months or less qualify as cash equivalents. Original maturity means original maturity to the entity holding the investment.

Exploration costs may be incurred both before acquiring the related property (sometimes referred to in part as prospecting costs) and after acquiring the property. Principal types of exploration costs, which include depreciation and applicable operating costs of support equipment and facilities and other costs of exploration activities, are: (i) Costs of topographical, geographical and geophysical studies, rights of access to properties to conduct those studies, and salaries and other expenses of geologists, geophysical crews, and others conducting those studies. Collectively, these are sometimes referred to as geological and geophysical or \"\"G&G\"\" costs. (ii) Costs of carrying and retaining undeveloped properties, such as delay rentals, ad valorem taxes on properties, legal costs for title defense, and the maintenance of land and lease records. (iii) Dry hole contributions and bottom hole contributions. (iv) Costs of drilling and equipping exploratory wells.
