Rigs included in the M-I SWACO Rig Count are engaged in drilling and related operations, which include drilling, logging, cementing, coring, well testing, fishing, waiting on weather, running casing and blowout preventer (BOP) testing.

M-I SWACO US & Canada Rig Count

The US & Canada Rig Count is published every Tuesday; it includes the US and Canada, but excludes Mexico. A rig is included in the count if it is engaged in drilling and related operations. Workover and completion activity are explicitly excluded.

M-I SWACO Worldwide Rig Count

The M-I SWACO Worldwide Rig Count is the sum of the Worldwide Rig Count and the average of the weekly US & Canada rig counts for the calendar month.

The Worldwide Rig Count is tabulated monthly on a per country basis. A rig is included in the count if:

Unlike the US & Canada Rig Count, the Worldwide Rig Count may include completion activities if the rig continues directly from drilling and related operations to completion operations after reaching total depth (TD). Workover activities are explicitly excluded from the Worldwide Rig Count.

The M-I SWACO Worldwide Rig Count is published the second week of each month reflecting the previous month's data.

In January 2010, the global rig count was revised to include rigs that were previously considered unavailable to Western oilfield suppliers. This revision impacts the rig count totals for Russia, Kazakhstan, Azerbaijan, Turkmenistan, Japan, and Myanmar.  Prior to January 2010, the rig counts exclude rigs that were considered unavailable to Western oilfield suppliers, as this category of rigs was not captured by M-I SWACO’s field reporting system.  Also reflected in the restatement is a reclassification of workover rigs in Algeria and Abu Dhabi where these rigs were previously included in the drilling rig count due to definitional differences in these countries; these rigs will no longer be included in the drilling rig count.
