Environmental Risk and Well Integrity of Plugged and Abandoned Wells

SPE Annual Technical Conference and Exhibition, 2014
Abstract This paper is the third in a series of environmental risk assessments covering hydraulic fracturing (SPE 152596) and well construction (SPE 166142). Risk assessment and well failure from SPE literature and governmental agencies have been used to construct a detailed but non-company associated study of plug and abandonment (P&

The Engineering of Oil-well Abandonments

Transactions of the AIME, 1946
Abstract This paper presents the problem of oil-well abandonment as a group of studiesinvolving the compilation of physical well data, the use of special curves, maps and interpretative procedures, in order that operations can be analyzedand means for reducing costs can be effected. Methods for the

Abandonment of Wells in Shell Nigeria Operations

Proceedings of Nigeria Annual International Conference and Exhibition, 2004
Abstract Shell Petroleum Development Company of Nigeria Limited (SPDC) recently embarked on a campaign to abandon some wells in line with a corporate drive to enhance the safety of the wells in her portfolio. It is also to ensure that SPDC as a responsible operator aims to safeguard people and environment as required by law. The campaign

Verification of Well Abandonment Barriers

SPE Offshore Europe Conference and Exhibition, 2015
Abstract When setting two deep wellbore barriers in close proximity it can be difficult to be assured that the upper barrier has integrity. Only by measuring the pressure between the barriers can the integrity of the shallower barrier be verified.

Effect of Well Abandonments on EOR Potential

Journal of Petroleum Technology, 1991
Summary EOR holds significant potential for producing additional oil from known reservoirs in the U.S. However. the economical application of the tertiary processes required to produce this oil relies on the use of produce this oil relies on the use of existing wells as points of reservoir access.

Unconventional Abandonment of Gavilan 1W Well

Latin American and Caribbean Petroleum Engineering Conference, 2009
Abstract Gavilan 1W Well was drilled in 1970 by Texas Petroleum, in Colombia, near to border's Ecuador. Final depth 7.700 ft. – 41 API, 1% BSW, Q = 25 BFPD. Well was closed, without conventional abandonment. In 2001, We identified an illegally exploited well with a gas leak from the wellhead (THP= 1.000 psi). Ecopetrol S.A.

Field-/Well-Integrity Issues, Well-Abandonment Planning, and Workover Operations on an Inadequately Abandoned Well: Peace River, Alberta, Case Study

SPE Drilling & Completion, 2010
Summary Maintaining well integrity for field life-cycle operations is a major factor that must be taken into account in the planning and execution of all well-engineering activities. Some legacy wells are not properly abandoned to prevent the contamination of secondary reservoirs or groundwater from other producing hydrocarbons or from ...

The Integrity of Idle and Abandoned Wells in California

SPE Western Regional Meeting
Abstract One of the critical challenges of California's 2045 carbon neutrality plans is the sources of greenhouse gas emissions (GHG) and the states' methods to improve emissions. This work provides insight into plugged wells, idle wells, and their potential for emission of methane and emission interferences these wells have with the ...

Plug and Abandonment of Offshore Exploration Wells

Offshore Technology Conference, 2013
Abstract Plug and Abandonment (P&A) can easily contribute with 25% of the total costs of drilling exploration wells offshore Norway. Cost efficient P&A technology is therefore necessary to reduce cost of exploration drilling.
