I haven't seen much news on this lately. This is the best 'recent' article I could find.

Pemex drills 160 wells in Q3, records 8 discoveries
Mexico's state oil company Pemex drilled a total 160 wells in the third quarter this year, up 9.6% from 3Q06, the CEO of Pemex's E&P subsidiary (PEP) Carlos Morales Gil said in a conference call to discuss Q3 results.
Growth came only from development wells, which were up 14.2% year-on-year to 145, while the number of exploratory wells drilled fell to 15 from 19 in 3Q06.
The drop in exploratory wells was primarily due to lower drilling activity in the Burgos project in northern Mexico.
Of the 145 development wells, four were in the Cantarell field and five in the Ku-Maloob-Zaap (KMZ) fields.
Pemex also completed 23 workovers and two pipelines in Cantarell as well as 22 workovers and three pipelines on KMZ.
Further, the company began nitrogen injection of 115Mf3/d (3.3Mm3/d) on the Ku field, which will make way for the reclassification of some probable reserves to proven reserves.
GOING FORWARD
Pemex aims to drill a total 17 development wells on Cantarell and KMZ in 4Q07 and continue installation of the nitrogen recovery unit (NRU) for Cantarell that will begin operations in 1Q08.
"Going forward with the development of KMZ, the startup of nitrogen injection in KMZ and the development of the Aceite Terciario del Golfo project plus the other projects - plus the exploration discoveries we've had this year - we expect by the end of the year to have a replacement ratio for proven reserves of 50%," Morales Gil said in the conference call.
The reserve replacement ratio of proved hydrocarbons was 41% in 2006.

Mexican leftists vow to blockade airports, highways if oil opened to private investment

MEXICO CITY - Thousands of followers of a former leftist presidential candidate vowed on Sunday to close highways, airports and government buildings across Mexico if the legislature opens the country's state oil industry to private investment.
Chanting "The country should to be defended, not sold," the demonstrators raised their hands and bellowed "Yes!" when asked if they would participate in blockades and a possible general strike against reforms to open the industry.
"The theft of the oil industry would leave open the risk of a violent confrontation, which would bring us more suffering, political and social instability," said their leader, Andres Manuel Lopez Obrador.
