Thank you, Paul, and good morning, everyone. In the first quarter, the Fluids systems and Engineering segment generated revenues of $218 million, a 28% increase over last year's first quarter and a 1% sequential decline compared to our fourth quarter of 2011. North American revenues were $161 million, up 30% from last year's first quarter and a sequential 2% decline due to deterioration in our mid-continent completion services and equipment rental business, reduced activity in dry gas regions of the U.S. and an early spring breakup in Canada.
In the U.S., we saw solid gains in the Louisiana Gulf Coast, and we continue to see excellent results both year-over-year and sequentially from the oil and liquid-rich plays, such as the Woodford, Eagle Ford, Bakken shales and the Permian Basin. As we stated during last quarter's call, we have been actively migrating to the liquid plays for nearly a year now and expect that drilling in these areas will remain robust as activity in dry gas drilling continues to contract.
Because of this, our activity in the Barnett and Haynesville shales continues to decline. And consequently, our revenues in those areas were down 30% sequentially and now make up less than 11% of our North American revenues, a decrease from the 15% we had in the fourth quarter.
In the first quarter, sales from Evolution were up $14 million from the first quarter of 2011 to $23 million and flat sequentially. The technology continues to gain acceptance across a broad spectrum of customers and regions. At the end of the first quarter of 2012, Evolution has now been used in over 800 wells.
Now moving to our International business. Europe, the Middle East and Africa revenues held steady at $30 million as activity remained stable in Tunisia, Algeria and Romania. There were still no activity in Libya in the first quarter, but we expect their customers to start drilling again later in 2012.
In Brazil, revenues were down year-over-year but operating income improved modestly. Our DeepDrill water-based system, another example of our technology leadership, continues to perform well on both the Brazilian offshore and land markets. Asia Pacific continues to contribute nicely with $9 million in revenues in the quarter. Our announcement in March of a new 2-year contract to provide fluids and services on Australia's Northwest Continental shelf, represents an important step towards introducing our technology into the region.
Fluids segment reported operating income of $14 million in the first quarter, compared to $19.2 million a year ago and $25 million in the fourth quarter of 2011. The operating margin for the segment in the first quarter was 6.4%, down from the 11.3% that was achieved in both the first quarter and fourth quarter of 2011.
The margin decline was caused by a combination of factors: first, the ongoing barite shortage has caused a significant increase in our raw material costs. Although we have been diligent in passing these costs on to our customers, they rose at a rate above which we could feasibly offset in the quarter. As a result, our operating income was negatively impacted by approximately $2 million in the first quarter.
In addition, due to the tightness experienced in the barite supply during the first quarter, we temporarily reduced our third-party barite sales, causing an additional $2 million decline in income during the quarter. While we have recently seen some stabilization in barite pricing, we continue to work on passing these cost increases on to our customers, while concurrently working on developing additional long-term sources of barite supply. However, it may take several quarters to accomplish this initiatives.
In our mid-continent completion services and equipment rental business, we have seen competitors move underutilized assets out of the Haynesville and Barnett and redeploy them into the mid-continent region, resulting in increased competitive pressure on pricing. This increased competition contributed to a $3.5 million reduction in our service and equipment rental revenue and due to the relatively fixed cost structure in this business unit, negatively impacted operating income by nearly $3 million compared with the prior quarter.
In response to these changes, we have taken necessary actions to improve profitability in these evolving market. Also our first quarter was impacted by a weak revenue mix and operating cost inefficiencies associated with transition from dry gas areas into liquid plays. While we continue to shift our resources as the rigs move, not all of our customers are active in the liquid plays. Particularly, one of our key customers that operates exclusively in a dry gas region reduced the drilling program by 80%. So while we are offsetting the lost revenue stream from our dry gas areas, our margin levels do vary from customer to customer.
Additionally, due to the rate of transition that we experienced in the first quarter, there were operating cost efficiencies within the business. In other words, cost reductions in the areas of decline tend to lag the cost increases in areas of growth, resulting in some short-term cost inefficiencies to the business.
And last, some of the lost revenue in the quarter from the declining dry gas areas was offset by increases in lower margin product sales, which serve to reduce operating margin in the quarter. Most significantly, the first quarter included a $5 million increase in oil-based mud sales. All these muds are much lower margin product compared to our specialty offerings. Further, diesel fuel was the primary raw material in oil-based mud from which costs have been continually increasing over the past several months. Together, these factors were the major contributors to our operating income decline in the quarter.
Although we are disappointed with the earnings performance in the U.S. region, I would like to point out that the fundamentals of our business remain positive. Our customer base remains strong and diverse. Our rig count remains stable. We are maintaining our market share. Our rollout of the Evolution system continues to attract new customers and gain acceptance. And as a result of these fundamental strengths, our revenues remain strong and stable in the U.S.
We understand the issues that have led to the earnings decline and are taking the necessary corrective actions now. We anticipate that we will see gradual improvements in margins over the next several quarters and by the end of the year, operating margins from the U.S. Fluids Systems and Engineering business will return to the recent historical levels.
With that, I will now turn the call over to our CFO, Gregg Piontek.
