A new hydrocarbon study contradicts conventional wisdom about how methane is trapped in rock, revealing a new strategy to more easily access the valuable energy resource. "The most challenging issue facing the shale energy industry is the very low hydrocarbon recovery rates: less than 10 percent for oil and 20 percent for gas. Our study yielded new insights into the fundamental mechanisms governing hydrocarbon transport within shale nanopores," said Hongwu Xu, an author from Los Alamos National Laboratory's Earth and Environmental Sciences Division. "The results will ultimately help develop better pressure management strategies for enhancing unconventional hydrocarbon recovery." Most of U.S. natural gas is hidden deep within shale reservoirs. Low shale porosity and permeability make recovering natural gas in tight reservoirs challenging, especially in the late stage of well life. The pores are miniscule -- typically less than five nanometers -- and poorly understood. Understanding the hydrocarbon retention mechanisms deep underground is critical to increase methane recovering efficiency. Pressure management is a cheap and effective tool available to control production efficiency that can be readily adjusted during well operation -- but the study's multi-institution research team discovered a trade-off.

“Both of these structures were built in the 1980s and the infrastructure of these facilities is growing tired,” Doug Taylor, the district’s director of operations, told thevsupervisors. “The primary purpose for these projects is not so much a major renovation as you saw with Holland Middle School or Rolling Hills, but to replace the infrastructure with new HVAC and electrical systems,” explained Taylor. “This will air condition the buildings that aren’t air conditioned, and add HVAC systems that will address some of the pandemic issues with increased filtration. We’ll also be replacing electrical system, life review safety and others.” Both projects will be phased so that students can be relocated temporarily to the former Richboro Middle School, minimizing construction from two years to one and “save the taxpayers significant money by avoiding the use of modular classrooms as temporary space,” said Taylor. “We’re working within the footprint of the buildings and respecting the partitions within the buildings,” said Taylor. In granting preliminary-final land development approval for the projects, the supervisors waived the parks and recreation fee and lieu. They also reduced its permit fees for the project, granting a 30 percent discount to the school district. The supervisors also required that the sidewalk being installed on Upper Holland Road in front of the Richboro Elementary School be made ADA compliant and that adequate lighting be installed. Prior to appearing before the planning commission and the board of supervisors, the district secured relief from the zoning hearing board for impervious surface and for signage.
