query using unallocated data, records with an ALLOC_PLUS value of N or X should be used. Without

referencing these columns, data and production in Texas will be double counted.

MAX_WTR_DAILY: Max water per day. If "Days On" is available it is used for the calculations, otherwise

the number of days in the month is used.

BOE_PRAC_IP: Barrel of oil equivalent (BOE) practical initial production (PRAC IP). (Prac IP is the based

on the second month of production to represent the first "full" month producing). BOE = oil + (gas/6). If

"Days On" is available it is used for the calculations, otherwise the number of days in the month is used.

So if Jan was the first production record and the second was Sept, Sept would be considered the second

month for Prac IP calculations.

oil + (gas / 6 ).

PEAK_BOE_MONTH_NO: The month number of the peak BOE volume. If it occurred in the first month of

### NPH_API_NOS

Mapping of all API numbers to a unique ENTITY_ID. This table allows you to locate a producing entity

based on the API number. For example, in Texas, production is reported on the lease level, but you can

have multiple wells on a lease. With this table you can query the ALL_API_NO field, get back theENTITY_ID and then query the PDEN_DESC table to locate the producing entity’s header information or

go directly to the monthly production volumes in PDEN_PROD.
