Johnna, thank you. In general, North American drilling activity continues to provide us constructive backdrop of Flotek's portfolio of oilfield technologies. That said, the shift to liquid-rich plays and away from depressed natural gas plays has had an impact on the overall mix of Flotek's business, as well as presented its shares of challenges in our sales and marketing efforts. As long as natural gas prices remains challenged, limitations on processing and growth in certain regions will be pervasive.
Our continued focus on developing a more balanced portfolio of oilfield technologies that positively impact both liquids as well as natural gas projects continue to yield positive results. Currently, our portfolio sales mix is approximately 70% liquids focused. We are pleased margins firmed incrementally in the quarter, a result of economies of scale and a reduction in input cost. While we don't expect significant pricing power in the near term, we do believe we can hold current levels and work to improve efficiencies as we continue to focus on margin improvement across our business lines.
Chemicals revenue for the 3 months ended March 31, 2012, totaled $47.7 million, an increase of $20.8 million or 76.9%, compared to $26.9 million for the 3 months ended March 31, 2011, due to increased oil-directed and liquids-rich natural gas drilling activity driven by increased global crude oil prices and stabilized liquids-rich natural gas prices. Increased product sales volumes of stimulation chemicals accounted for approximately $20 million of the period-over-period increase.
Chemicals gross margin for the first quarter of 2012 increased $9.6 million or 85.1% and increased 1.9% as a percentage of revenue as compared to the first quarter of 2011. The period-over-period increase is primarily attributable to cost management initiatives and vendor pricing negotiations, which resulted in raw material price reductions and purchasing efficiencies in 2012.
Income from operations increased $8.6 million or 100.9% period over period due to increased product sales, service volumes and improved pricing.
March was a record month for our Chemicals division. First quarter 2012 C&S sales increased 35% when compared to the fourth quarter and 72% when compared to the first quarter 2011 levels. Growth across unconventional resource plays, especially oily plays like the Bakken, Eagle Ford, Niobrara, continue to help accelerate sales. While the traditional April breakup had a meaningful impact on our business, we believe the overall growth trend remains intact for the balance of the second quarter.
We continue to make progress in enhanced oil recovery business, although our growth remains deliberate. Our core IOR [ph] CnF product has been pumped on 35 wells in the Permian Basin. Moreover, a newly developed CnF-based CO2 foam diversion product has been used to arrest premature breakthrough in our West Texas CO2 flood. While we are encouraged by our progress in the EOR arena, we are still in the early stages of development and anticipate meaningful growth to come in late 2012 and into the following years.
We continue to make steady progress in international markets. Sales in the key Middle East and North African markets continue to grow, and we're seeing more opportunities in South America. Our work in Russia is in the commercial testing phase. And assuming we continue to make progress, we believe commercial sales will be realized this year.
Drilling revenue for the 3 months ended March 31, 2012, totaled $29 million, an increase of $6.3 million or 28% compared to $22.6 million for the 3 months ended March 31, 2011. The favorable variance resulted from domestic and international market share growth, penetration with both new and existing customers, changes in customer's product mix demands, increased rig count, increased lost-in-hole revenue, favorable crude oil commodity prices, new product development, specialized customer demand for existing product adaptation, continued cross segment sales marketing efforts, sales force revitalization and competitive pricing relief.
Drilling gross margin for the 3 months ended March 31, 2012, increased by $2.6 million or 28.7% to $11.5 million from $8.9 million for the same comparable period over period. Drilling income from operations for the 3 months ended March 31, 2012, increased by $0.9 million or 18.1% to $5.5 million from $4.7 million for the same comparable period in 2011.
We are pleased with the progress of the Drilling business. While the slump in natural gas prices has impacted us in areas such as the Marcellus Shale and the Haynesville Shale, our efforts in the Permian, the South Texas, Eagle Ford and other liquid-rich basins have more than offset the challenges. For example, sequential revenue growth in the Eagle Ford was 44% in the first quarter.
Our Cavo drilling motor division also continues to post solid results with revenue up 19% sequentially and 33% when compared to the first quarter of 2011. In addition, other tools as such as jars and shock subs have contributed to our growth with revenues up 26% and 42%, respectively, year-over-year.
Finally, growth in Teledrift continues in nearly all basins. We introduced our remote monitoring telemetry system in field trials during the quarter and now have a mobile application available for use. We expect the availability of this advanced technology, as well as new state regulations, to provide a positive environment for improved market share through the balance of 2012.
We recently opened a Denver sales office to better serve both the Rockies and the Williston Basin. We remain constructive on our growth opportunities in those liquid-rich areas.
Finally, we continue to make progress on the international front. In addition to continued activity in South America and the Middle East, we recently shipped a series of Teledrift tools Kazakhstan for multiyear project. We continue to evaluate other international opportunities to ensure an appropriate balance of opportunity and risk.
Artificial Lift revenue for the 3 months ended March 31, 2012, totaled $2.6 million, a decrease of $0.8 million or 23.3% compared to $3.3 million for the 3 months ended March 31, 2011, due to lower unit installation activity resulting from lower natural gas drilling activity driven by low natural gas prices as compared to 2011. The decrease in revenue was partially offset by an increase of $0.4 million order from an international customer.
While the gas-centric Artificial Lift business remains severely challenged, we are upbeat about opportunities we have seen related to our Petrovalve product. We've recently installed Petrovalves in projects in the D-J Basin and the Bakken Shale, some of the first uses of the valve in domestic production systems. Early indications suggest solid results, and we will continue to seek additional opportunities to expose new customers to the product. In addition, international opportunities with [indiscernible] and [indiscernible] for Petrovalve sales should give an international boost to revenues later in 2012.
We are excited about the opportunities in front of us for the balance of 2012. And while we will remain vigilant in our careful watch of commodity pricing and drilling activities, we believe we are well positioned to gain market share as we focus on our mantra of profitable growth.
With that, I'd like to turn the call back to John Chisholm.
