gold_well_injection
Monthly volumes injected INTO disposal, enhanced-recovery and storage wells: water (BBL) and gas (MCF), one row per injection well per month, with the injection type. This is fluid going down the hole; produced water lives on the production table. NULL means not reported, never zero.

Columns
| Column | Type | Nullable | Description |
|---|---|---|---|
well_id |
string | no | Join key to the well register: the injection or disposal well that received the fluid. Always populated. Most injection wells are not producers (many are converted to disposal), so this population is largely separate from the monthly production series. |
date |
date | no | Injection month, always the first day of the month. |
year |
int16 | no | Calendar year of the injection month (equals the year of date). Provided for fast year-level filtering and partition pruning. |
water_injected |
int32 | yes | Liquid injected during the month, in barrels (BBL): saltwater for disposal wells, water for waterfloods. The dominant injection signal. NULL means no liquid volume was reported that month (never zero); 0 is a reported zero. Where a source reports per-zone volumes (e.g. Alaska, California), zones are summed to the well-month. |
gas_injected |
int32 | yes | Gas injected during the month, in thousand cubic feet (MCF): enhanced recovery, pressure maintenance, or cycling. NULL where not reported, never zero. CO2 injected for enhanced recovery and reported in MCF is included here. |
injection_type |
string | yes | The well's injection class for this volume: disposal (saltwater disposal), enhanced_recovery (waterflood / enhanced oil recovery), storage (hydrocarbon or gas storage), or other. Mapped from the regulator's well-class code. Carried per row because a well can change injection purpose over its life. NULL where unknown.
Values: disposal · enhanced_recovery · storage · other. |
record_origin |
string | no | How the volume was derived: reported = the source reports it directly per well; lease_allocated = a field or unit total split to wells using the same allocation weights as the monthly production series; wellstar_estimated = California's own preliminary-estimate flag on the source record, still a source-reported volume, marked provisional by the source, never one we modeled; identity_inferred = the volume is the source's own well-month figure, but the source omitted which well it belongs to; the well shown is our attribution, recovered by matching the row's stable attributes (for example the operator and the well's packer depth) against the same source's named filings in adjacent years, and published only where that match is unambiguous and its measured accuracy clears a 95% floor. Always populated.
Values: reported · lease_allocated · wellstar_estimated · identity_inferred. |
