Development of bismuth-based solutions for well plugging and abandonment: A review
Hmadeh, Lewaa; Jaculli, Marcelo Anunciacao; Elahifar, Behzad; Sangesland, Sigbjørn (Journal article; Peer reviewed, 2024)Plugging and abandonment (P&A) is a crucial step of the well life cycle. Regardless of how long one stretches the productive life of a well, P&A operations will have to be carried out eventually. The current panorama of ... -
The effect of temperature on the sealability of bismuth–tin alloy plugs
Hmadeh, Lewaa; Anunciacao Jaculli, Marcelo; Vedvik, Noralf; Elahifar, Behzad; Sangesland, Sigbjørn (Journal article; Peer reviewed, 2024)Innovative solutions for plugging oil and gas wells are becoming increasingly important to ensure safe operations, save costs, and guarantee that the wells are sealed with a long-term perspective. Among these innovations, ... -
The effect of well temperature on the microstructure and the mechanical performance of bismuth-based plugs in well plugging and abandonment operations
Manataki, Andriani; Hmadeh, Lewaa; Sørensen, Bjørn Eske; Kontis, Paraskevas; Sangesland, Sigbjørn (Journal article; Peer reviewed, 2024)Bismuth-tin (BiSn) alloys are considered promising candidates as potential alternatives to cement for well plugging and abandonment (P&A) applications to prevent any uncontrolled flow of deep reservoir fluids to the surface. ... -
Experimental Testing and Qualification of Bismuth in the Laboratory: The Utilisation of Bismuth Plugs in Plug and Abandonment
Essén, Tora (Master thesis, 2024)Nedstengning av allerede eksisterende brønner på norsk sokkel, nye brønner som bores og de mange brønnene som må plugges på nytt, er en økende bekymring i petroleumsindustrien. Plugging av brønner er en tidkrevende og ... -
A Full Laboratory Study on the Physical and Mechanical Properties of a Bismuth Plug
Hmadeh, Lewaa; Elahifar, Behzad; Sangesland, Sigbjørn; Abrahamsen, Andreas Elmer (Chapter, 2023)Well plugging and abandonment can be very expensive, time consuming and problematic. This is because it is the least considered process during a well's life cycle. Setting a plug downhole in an efficient and successful ... -
A Sealability Study on Bismuth-Tin Alloys for Plugging and Abandonment of Wells
Hmadeh, Lewaa; Manataki, Andriani; Anunciacao Jaculli, Marcelo; Elahifar, Behzad; Sangesland, Sigbjørn (Journal article; Peer reviewed, 2024)The use of bismuth alloys as a barrier material for plugging and abandonment (P&A) has gained traction in the literature due to the large number of wells scheduled to be plugged and abandoned. In addition, many questions ... -
The Beginning of the End: A Digital Planning of P&A Operations
Hmadeh, Lewaa (Master thesis, 2021)Som det er kjent, kan operasjoner for å plugge og forlate brønner være svært tidkrevende og kostbare. Slike operasjoner kan ha en kostnads tilsvarende den opprinnelige boreoperasjonen. Å etablere kostnadseffektive P & ...
