Numerical Simulation of Abandoned Gob Methane Drainage through Surface Vertical Wells. [PDF]

open access: yesPLoS ONE, 2015
The influence of the ventilation system on the abandoned gob weakens, so the gas seepage characteristics in the abandoned gob are significantly different from those in a normal mining gob.

ECONOMIC AND LEGAL ASPECT OF THE NEGATIVE IMPACT OF OIL AND GAS WELLS ON THE ENVIRONMENT

open access: yesВестник университета, 2020
The negative impact on the environment is carried out from almost all oil and gas facilities. One of such objects are wells of any purpose. The causes of negative impacts on the environment from plugged and abandoned wells were identified in the course ...

Analysis of the financial assurance problem for decommissioning of oil and gas wells and facilities [PDF]

open access: yesАктуальные проблемы нефти и газа, 2022
The harmful effects of oil and gas projects on the environment are not limited to the production period. Unlike operating production facilities, control over the state of abandoned wells and fields falls on the state.

Reducing oil and gas well leakage: a review of leakage drivers, methane detection and repair options

open access: yesEnvironmental Research: Infrastructure and Sustainability, 2023
Oil and gas wells (OGWs) with integrity failures can be a conduit for methane and contaminant leakage to groundwater aquifers, surface water bodies and the atmosphere.

Casing failure identification of long-abandoned geothermal wells in Field Dieng, Indonesia

open access: yesGeothermal Energy, 2019
Integrity issues create challenges for maintaining the production of mature geothermal wells. Such problems are likely to occur in wells designed according to oil and gas standards, without considering the extreme geothermal environment.

Oil and gas wells and pipelines on U.S. wildlife refuges: challenges for managers. [PDF]

open access: yesPLoS ONE, 2015
The increased demand for oil and gas places a burden on lands set aside for natural resource conservation. Oil and gas development alters the environment locally and on a much broader spatial scale depending on the intensity and extent of mineral ...

Well Integrity Management: A Recommendation for Indonesia's Well Life Cycle

open access: yesJournal of Earth Energy Engineering, 2021
Indonesia oil and gas field mostly are brownfields which were drilled in the late '40s up to '90s. Development and further development of a new structure throughout the years is done, including drilling exploration wells with new play and development ...

Measurement of methane emissions from abandoned oil and gas wells in Hillman State Park, Pennsylvania

open access: yesCarbon Management, 2018
Abandoned oil and gas wells, improperly plugged or unplugged, present a risk to current and future oil and gas development because they provide a potential pathway for unwanted gas and fluid migration to the surface.

Feasibility of Detecting Low-Level Methane Emissions from Abandoned Oil Wells Using a Multi-Band, Multi-Pass Satellite Approach [PDF]

open access: yesE3S Web of Conferences
In this study, we develop a multi-band, multi-path (MBMP) model using shortwave infrared (SWIR) data to quantify point-source methane emissions from abandoned oil wells.
