After oil is measured by tank gauging under §§ 3174.5 and 3174.6 of this subpart, the operator, purchaser, or transporter, as appropriate, must complete a uniquely numbered measurement ticket, in either paper or electronic format, with the following information:\n(1) Lease, unit PA, or CA number;\n(2) Unique tank number and nominal tank capacity;\n(3) Opening and closing dates and times;\n(4) Opening and closing gauges and observed temperatures in °F;\n(5) Observed volume for opening and closing gauge, using tank specific calibration charts (see § 3174.5(c));\n(6) Total gross standard volume removed from the tank following API 11.1 (incorporated by reference, see § 3174.3);\n(7) Observed API oil gravity and temperature in °F;\n(8) API oil gravity at 60 °F, following API 11.1 (incorporated by reference, see § 3174.3);\n(9) S\u0026W content percent;\n(10) Unique number of each seal removed and installed;\n(11) Name of the individual performing the tank gauging; and\n(12) Name of the operator.\n(b) LACT system and CMS. (1) At the beginning of every month, and, unless the operator is using a flow computer under § 3174.10, before conducting proving operations on a LACT system, the operator, purchaser, or transporter, as appropriate, must complete a uniquely numbered measurement ticket, in either paper or electronic format, with the following information:\n(i) Lease, unit PA, or CA number;\n(ii) Unique meter ID number;\n(iii) Opening and closing dates;\n(iv) Opening and closing totalizer readings of the indicated volume;\n(v) Meter factor, indicating if it is a composite meter factor;\n(vi) Total gross standard volume removed through the LACT system or CMS;\n(vii) API oil gravity. For API oil gravity determined from a composite sample, the observed API oil gravity and temperature must be indicated in °F and the API oil gravity must be indicated at 60 °F. For API oil gravity determined from average density (CMS only), the average uncorrected density must be determined by the CMS;\n(viii) The average temperature in °F;\n(ix) The average flowing pressure in psig;\n(x) S\u0026W content percent;\n(xi) Unique number of each seal removed and installed;\n(xii) Name of the purchaser's representative; and\n(xiii) Name of the operator.\n(2) Any accumulators used in the determination of average pressure, average temperature, and average density must be reset to zero whenever a new measurement ticket is opened.","path":["Title 43—Public Lands: Interior","Subtitle B—Regulations Relating to Public Lands","CHAPTER II—BUREAU OF LAND MANAGEMENT, DEPARTMENT OF THE INTERIOR","SUBCHAPTER C—MINERALS MANAGEMENT (3000)","PART 3170—ONSHORE OIL AND GAS PRODUCTION","Subpart 3174—Measurement of Oil"],"source_url":"https://www.ecfr.gov/api/versioner/v1/full/2026-08-25/title-43.xml","current_through":"2026-08-25","vintage":"","retrieved_at":"2026-08-27T02:26:15Z","sha256":"abfa59e9c47c5b2dd13bb252c3d3cb4098ab3953e5ee862889c972b75284c414","source_id":"us-cfr","stale":true,"prev":"us/43-cfr-3174.11","next":"us/43-cfr-3174.13"},"notice":"GroundRules: Original legal text.
