FACTBOX-Mexico energy reform debate

Aug 20 (Reuters) - Latest developments as Mexico's ruling conservatives court opposition lawmakers to approve an energy reform to allow more private investment in the state-controlled oil industry in hope of bolstering falling output.

Compiled from Reuters stories, Mexican newspaper reports, television and radio.

* A key centrist opposition party could vote this weekend to eliminate a clause in its party bylaws that rejects all efforts to privatize the oil industry, newspaper Reforma reported. The measure, if passed, could signal a toning down of energy nationalism in the Institutional Revolutionary Party, or PRI.

* President Felipe Calderon's ruling conservative party, known as the PAN, could propose a reform of the pension system at the state-run oil monopoly Pemex, Reforma reported.

* Hoping to shore up flagging production and reserves in the world's No. 6 oil producer, Calderon proposes to let Pemex sweeten oil field service contracts with private companies using performance-based bonuses. Left-wingers say that would violate a ban on private companies exploring for and producing oil in Mexico.

* PRI congressman will meet this week to discuss the party's plans for the next legislative session, which opens on September 1. On the table are revisions to the PRI's existing counter-proposal for energy reform as well as priorities for the 2009 budget. (Reporting by Miguel Angel Gutierrez)
