IADC Daily Drilling Report (Tour Report)
(Tour is pronounced as tower by field hands)
The International Association of Drilling Contractors’ IADC daily drilling report is a copyright form that was called a saddle blanket since it was three pages wide. It was filled in by hand at the rig location and it had multiple copies that were different colors. That meant the person had to press hard so the bottom copies could be read. If you wanted to make a copy of a page, you had to copy and tape three pages together. As we predicted years earlier, the computer simplified the input, handling, forwarding and storage of these rig reports. There are similarities between the IADC daily drilling (tour) report and the daily drilling report (DDR). However, the DDR could be in summary form and called in every morning for timely, early-morning reporting. These reports are very important since they document the daily drilling activities for future reference and help to verify vendor services. Usually both reports are on a 6 a.m. to 6 a.m. basis.
I once asked the drilling engineer, Wayne Miller who worked for Tiger Mike, what some of the abbreviations were in the report since they were new to me. He said the reason that happened is because he made up some of the abbreviations as he prepared the daily reports that had been called into him each morning.
On page 1, the report includes: report number and page number. It includes the Operator’s name, rig contractor’s name and rig number. A signature is required by both the Operator’s representative and rig contractor’s tool pusher. Listed is the drill pipe, drilling assembly, bit, mud and pump information and remarks section.
The bit record is important since it gives the bit number, size, IADC code, manufacturer, type, serial no, Jts, TFA, Depth out and end, total footage drilled and total hours. That is useful for bit usage analysis and bit control. The mud record is important since it gives the mud & chemicals added which can be very important controlling the count of bags of specific items mixed into the mud.
At the far left of the form is a time distribution column by code which summarizes the hours spent daily. Obviously, management wants to see a lot of drilling hours and no fishing hours. This is very important since the rig contract only allows the rig contractor a limited number of hours for rig repairs which are deducted from the rig contractor’s monthly invoice.
On page 2, the report includes: field or district, county, state/country, wire line record and last casing / liner / tubing run. Also listed are: depth interval, drill/ream/core and core No, formation, rotary table speed, weight on bit, pump pressure and pumps as well as a deviation record. The number of tubular joints and footages run are important to account for the usage and surplus. It details the operations in sequence by line item with remarks showing start and stop times of each operation. There might be only one line item which would be drilling; however, there are usually many line items as things can happen on a minute-by minute basis.
There are two rig worker shifts (or tours) which are the night tour and day tour – the night tour is at the top of the page and day tour at the bottom of the page.
On page 3, the report includes the names and functions of the workers with the hours they worked. This is very important since many “crew shorts” can reduce the efficiency of the rig due to the lack of workers; and therefore, the rig contractor should reduce the monthly invoice by the shortages.
