HY-BON/EDI Blog: Quad O Compliance and Vent Gas Management

Jan 2, 2015
Flaring and venting of natural gas from oil and gas operations in Texas are regulated by the Railroad Commission of Texas (RRC) and the Texas Commission on Environmental Quality (TCEQ). The RRC regulations strive to maximize production and minimize waste. The TCEQ regulations focus on limiting air pollution. Regulations from these two agencies include permitting and emergency reporting requirements.  For both agencies, the preferred method to reduce waste, maximize production and eliminate air … Texas Well Natural Gas Flaring and Venting Permitting

On December 31, 2014, the EPA published in the Federal Register updates and clarifications to 40 CFR 60 Subpart OOOO (aka Quad O). The notification includes a summary fact sheet for the Quad O revisions at: http://www.epa.gov/airquality/oilandgas/pdfs/20141219fs.pdf.  These changes are expected to be followed by other proposed modifications to Quad O in 2015.  March 23, 2015 Proposed Changes to NSPS OOOO - Updated March 31, 2015 In a Federal Register Notice dated March 23, 2015, the EPA propo… NSPS OOOO (Quad O) 1.5 Update - Revised March 31, 2015

Process Description Operators are often required to dehydrate natural gas streams that are saturated with water vapor to meet pipeline specifications.  Water in a natural gas pipelines can result in hydrates that obstruct or plug the pipe.  Also, water vapor in a pipeline can cause corrosion due to the presence of carbon dioxide (CO2) or hydrogen sulfide (H2S) in the natural gas.  Most natural gas producers use triethylene glycol (TEG) dehydrators to remove water from natural gas to meet pipe… Air Pollution and Glycol Dehydration

Process Description Casinghead gas is natural gas produced with oil in oil wells and is usually the flash gas from the oil reservoir. Casinghead gas collects in the annular space between the well tubing and casing of an oil well. The weight of the casinghead gas contributes to reducing the bottom hole pressure and lowering well production – specifically by holding a back-pressure against the formation.  Reducing the gas pressure on the well casing (annulus) can increase oil production.  The goa… Overcome the Impasse with Casinghead Gas

What is a SEP? SEPs (Supplemental Environmental Projects) are voluntary projects that reduce pollution discharges or improve the quality of the environment. These projects are typically a part of a settlement agreement for an environmental enforcement action. Some state environmental regulatory agencies use the term Beneficial Environmental Projects (BEP) for their state only programs.  A respondent in an enforcement action (federal or state) may negotiate an agreement to perform a SEP in ord… If You Have a Misstep use a “SEP” (Supplemental Environmental Project)

Buying and selling oil and gas properties is a mainstay of the oil and gas industry – and prudent buyers conduct “due diligence” for their acquisition(s). For the process, companies include a Phase I Environmental Site Assessment (ESA) to determine if any existing or potential recognized environmental conditions are present  - indicating contamination with oil or other chemicals.  The Phase I ESA includes a site visit and review of reasonably ascertainable information. NORM surveys, sampling of… Use Vigilance for Air Due Diligence

Many oil and gas operators use environmental consultants or in-house specialists to prepare air permit applications for oil and gas production facilities. This is needed since air quality rules can be complicated due to the alphabet soup of regulations affecting the industry.  The result is often that only a few people fully understand what is required for regulatory compliance.  Also, the permit that a company receives from the regulator may not clearly spell out what is required for compliance… Unveil the Mystique of Air Permit Speak

EPA Gas STAR Gold Program for Methane The EPA’s Natural Gas STAR Program is a voluntary partnership designed to inspire oil and natural gas companies to implement profitable technologies and practices that reduce methane emissions.  The program has many success stories since its beginning in 1993.  If your company has not been active in Gas STAR program, consider participating beginning this year.       With all of the focus on the NSPS OOOO (Quad O) requirements for mandatory reduction of VO… Get Sold on EPA Gas STAR Gold Program for Methane Reductions

Use the Power of the Vapor Recovery Tower Operators are always looking for ways to improve vapor recovery unit (VRU) performance and to avoid NSPS OOOO (Quad O).  Using a vapor recovery tower along with a VRU, a facility can increase production of natural gas and decrease air emissions.     Vapor recovery towers (VRTs) are tall, vertical separators used to recover flash gas emissions that would be generated in a crude oil storage tank.  Flash gas results from natural gas coming out of solutio… Use the Power of the Vapor Recovery Tower

Oil and gas operators know that obtaining the correct oil and gas air permits for their operations is essential.  There is truly an “Alphabet Soup” of air pollution regulations to follow for oil and gas operations.  Knowing the different air permit types in no longer the domain of only the environmental department and consultants.  These permits affect operations, engineering, safety, legal and accounting departments.  Permitting the facility correctly can save your company money and lower you…
