9-331A within 15 days after the work is done, except where such record is included in the log (Form 9-330) or is a part of a record of other subsequent work done (Form 9-331A) or is a part of an abandonment record filed within that period. The subsequent record of use of explosive or chemicals shall include a statement of the amount and the nature of the material used, its exact location and distribution in the well (by depths), and the method used to localize its effects. The record shall also contain an accurate statement of the dates and daily production of oil, gas, and water for each of the last 10 producing days preceding the use of explosive or chemicals and a similar statement of production after the work is done. In addition, this report must include other pertinent information, such as the depth to which the well was cleaned out, the time spent in bailing and cleaning out, and any injuries to the casing or well.

(g) Record of perforating casing (Form 9-331A). Usually a statement covering the details of perforated casing in a well is made on the log form. When perforations are made after the log has been submitted, a report of the work must be made in triplicate (Form 9-331A) to the supervisor or his local representative. *Prior notice need not be given for such work, except that if it is intended to perforate casing that has excluded water from the well, a notice in triplicate of intention to perforate and approval of the supervisor or his local representative are necessary before the work is begun.

(h) Notice of intention to pull or otherwise alter casing (Form 9-331A). If it is desired to pull a portion or all of a string of casing, or to rip, perforate, or otherwise alter casing that has excluded water from a well, a notice (Form 9-331A) of such work must be given in triplicate and the approval of the supervisor or his local representative obtained before the work is started.

(i) Notice of intention to abandon well (Form 9-331A). Before beginning abandonment work on any well, whether drilling well, oil or gas well, water well, or so-called dry hole, notice of intention to abandon shall be filed in triplicate on Form 9-331A with the supervisor or his local representative and approval obtained before the work is started. The notice of intention to abandon must show the reason for abandonment and must be accompanied by a complete log, in duplicate, of the well to date, provided the complete log has not been filed previously, and must give a detailed statement of the proposed work, including such information as kind, location, and length of plugs (by depths) and plans for mudding, cementing, shooting, testing, and removing casing, as well as any other pertinent information.

(j) Subsequent report of abandonment (Form 9-331A). After a well is abandoned or plugged a subsequent record of work done must be filed in triplicate with the supervisor or his local representative. This record shall be filed separately (on Form 9–331A) within 15 days after the work is done. The subsequent report of abandonment shall give a detailed account of the manner in which the abandonment or plugging work was carried out, including the nature and quantities of materials used in plugging and the location and extent (by depths) of the plugs of different materials; records

of any tests or measurements made and of the amount, size, and location (by depths) of casing left in the well; and a detailed statement of the volume of mud fluid used, the pressure attained in mudding, and the names and positions of employees who carried on the work. If an attempt was made to part any casing, a complete report of the methods used and results obtained must be included.

(k) Supplementary well history (Form 9-331A). A report of all work done on any well since the filing of the log form (Form 9-330) or the last report covering work on the well must be filed in triplicate with the supervisor or his local representative on Form 9-331A within 15 days after completion of the particular work, or before, if called for by the supervisor or his representative.** [Sec. 5 (b)]

221.50 Log and history of well (Form 9-330). The lessee shall furnish in duplicate, on Form 9-330, to the supervisor or his representative, not later than 15 days after the completion of each well, a complete and accurate log and history, in chronologic order, of all operations conducted on the well. If a log is compiled for geologic information from cores or formation samples, duplicate copies of such log shall be filed in addition to the regular log. The lessee shall require the drillers, whether using company labor or contract labor, to record accurately the depth, character, fluid content, and fluid levels, where possible, of each formation as it is penetrated, together with all other pertinent information obtained in drilling the well. The practice of compiling well logs from memory, after the work has been completed, will not be permitted.*+ [Sec. 5 (c)]

221.51 Lessee's monthly report of operations (Form 9-329). A separate report of operations for each lease must be made for each calendar month, beginning with the month in which drilling operations are initiated, and must be filed in duplicate with the supervisor or his local representative on or before the sixth day of the succeeding month, unless an extension of time for the filing of such report is granted by the supervisor or his representative. The report on this form constitutes a general summary of the status of operations on the leased lands and, whatever such status may be, the report must be submitted each month until the lease is terminated or until omission of the report is authorized by the supervisor or his representative.

(a) Information to be shown. In order that the supervisor or his representative may obtain from this form the desired information, it is particularly necessary that for each calendar month:

(1) The lease be identified by inserting the name of the United States land office and the serial number, or in the case of Indian lands the lease number and lessor's name, in the space provided in the upper right corner;

(2) Each well be listed separately by number, its location be given by 40-acre subdivision (14 14 sec. or lot), section number, township, and range;

(3) The number of days each well produced, whether oil or gas, and the number of days each input well was in operation be stated;

**For statutory and source citations, see note to § 221.1.

(4) The proper columns show the quantity of oil, gas, and water produced and the total amount of gasoline recovered (total sales as distinguished from the total production here required should be shown in the footnote);

(5) The "Remarks" column show the name, character, and depth of each formation in wells being drilled (active or suspended), the date such depth was reached, the date and reason for every shutdown, the names and depths of important formation changes and contents of formations, the amount and size of any casing run since last report, the dates and results of any tests such as production, water shut-off, or gasoline content, and any other noteworthy information on operations not specifically provided for in the form.

(b) Form to be report of all operations during month. It is intended that this form shall be a report of all operations conducted on each well during the month and that it shall show status of operations in progress on the last day of the month.

(c) Information required in footnote (Form 9-329). The information required in the footnote must be given in barrels of oil, thousands of cubic feet of gas, and gallons of gasoline. If no runs or sales were made during the calendar month, the report must so state.

(d) When oil and gas, or oil, gas, and gasoline concurrently produced from same lease. When oil and gas, or oil, gas, and gasoline, are concurrently produced from the same lease, separate reports on this form should be submitted for oil and for gas and gasoline, unless otherwise authorized or directed by the supervisor.

(e) Status of wells to be reported accurately. The lessee must report accurately the status of all wells on the leased lands.*+ [Sec. 5 (d)]

221.52 Daily report of gas-producing wells (Form 9-352).
