A completed subsea oil well was abandoned in 95 ft of water offshore Louisiana. This paper describes the abandonment procedures, drilling, completion, production operations, and the technical analysis of the recovered Christmas tree. Single-well subsea systems are available for development of shallow-water reserves, but still need improving.

Enhancing Well Construction for More Efficient Well Abandonment
SPE/IATMI Asia Pacific Oil & Gas Conference and Exhibition, 2017Abstract The lack of planning for well plug and abandonment (P&A) during the well-construction phase can significantly contribute to the extended operational time and associated high cost of P&A. The impact on time and cost is mainly due to insufficient well data, uncertain casing cement integrity, and lack of information on ...

Environmental Risk and Well Integrity of Plugged and Abandoned Wells
SPE Annual Technical Conference and Exhibition, 2014Abstract 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, 1946Abstract 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, 2004Abstract 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, 2015Abstract 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, 1991Summary 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, 2009Abstract 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.

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 ...
