Our portfolio of term customer contracts provides a base level of activity and revenue, and as at April 24, 2013 we have term contracts in place for an average of 55 rigs in Canada, 40 in the United States and 10 internationally for the second quarter of 2013 and an average of 52 rig contracts in Canada, 36 in the United States and 10 internationally for the full year. In Canada, term contracted rigs normally generate 250 utilization days per rig year because of the seasonal nature of well access. In most regions in the United States and internationally, term contracts normally generate 365 utilization days per rig year.
In the United States, our average active rig count in the quarter was 81 rigs, down 22 rigs over the first quarter in 2012 and down 6 rigs over the fourth quarter of 2012. We currently have 79 rigs active in the United States and expect our rig count in the United States to remain relatively unchanged over the coming months.
In Canada, our average active rig count in the quarter was 123 rigs, down 11 rigs over the first quarter in 2012 and up 34 rigs over the fourth quarter of 2012. We expect typical seasonal softness through the second quarter in Canada, but in the third quarter expect to benefit from the fleet enhancements made over the past few years when compared to the prior year period.
Internationally, our average active rig count in the quarter was eight rigs, up six over the first quarter in 2012 and in line with the fourth quarter of 2012. Our active rig count internationally is expected to grow by three rigs over the next two quarters as our two rigs in Kurdistan begin drilling operations and we have an additional rig going to work in Mexico.
To date in 2013, drilling activity has been lower in Canada and the United States compared to this time last year. According to industry sources, as at April 19, 2013, the U.S. active land drilling rig count was down about 11% from the same point last year and the Canadian active land drilling rig count was down about 14%. Despite the active industry rig count softness, demand for Tier 1 assets continues to be strong, benefiting the drilling contractors with a high percentage of Tier 1 assets.
The trend toward oil-directed drilling in North America has continued in 2013. During the quarter approximately 74% of the Canadian industry's active rigs and 76% of the U.S. industry's active rigs were drilling for oil targets, compared to 72% and 64%, respectively at the same time last year.
We expect capital spending in 2013 to be approximately $533 million, of which $131 million was spent during the first quarter:
-- $237 for expansion capital, which includes the cost to complete the two remaining drilling rigs from the 2012 new build rig program, one new rig build for the North American market, the cost to complete about 50 percent of two new build rigs going to Kuwait, long lead equipment and new equipment for our Completion and Production Services segment.-- $119 million for upgrade capital, which includes the upgrade of approximately 20 rigs, including the two rigs going to Northern Iraq in the Kurdistan region and to purchase long lead time items for our capital inventory.-- $177 for sustaining and infrastructure expenditures, which is based on currently anticipated activity levels and some of the cost to consolidate and upgrade our operating facilities.
