Generally when they are run inside casing they will be run with a smooth OD to prevent milling a hole through the side of the casing wall Section mills are generally run to cut sections of casing The may be used in PA situations to allow the setting of a balanced plug from one wall of the wellbore to the other

Cementing High Level Cementing jobs can be categorized as one of three types There is a Primary Cement Job where a cement sheath is placed around a casing or liner string Some of the reasons for doing this could include zonal isolation to prevent migration of fluids in the annulus support for the casing or liner string or protection of the casing string from corrosive formation fluids

alternative cement milling process Though dry process cement plants are advantageous over wet process plants due to significant energy savings they experience additional material handling problems during feeding milling and calcination Cement plants continue to seeks ways to reduce fossil fuel consumption through use of alternative fuels

Long casing strings may require higher strength materials on the upper portion of the string to withstand the string load Lower portions of the string may be assembled with casing of a greater wall thickness to withstand the extreme pressures likely at depth Casing is

1 Well status prior to section milling operations Consult cement bond logs to assess the degree of casing-cement bonding over the casing section to be milled Mechanical performance will be improved across well cemented intervals where lateral play is minimised Selection of Window Interval 2

Deep Casing Tools' first prototype Casing Cement Breaker was trialled in a well on Equinor's Huldra field in the Norwegian North Sea as part of a plugging and abandonment program (PA) just weeks after the Norwegian operator's staff were introduced to the tool by drilling services company Archer The innovative Casing Cement Breaker deals with problem cement in casing which hinders

CHALLENGE Plug and abandonment rules in Norway require that cement plugs be placed in contact with formation face to assure long term elimination of shallow gas migration SOLUTION Procedure is to section mill 40 ft of 13-3/8 in casing away and under ream to 18-1/2 in in the original 17- in hole to remove any cement

So compatibility of cement and milling fluid is strongly dependent on the chemistry and properties of milling fluid therefore milling fluids will be reviewed briefly 7 1 2 Milling Fluid When casing is milled away the generated debris known as swarf (Fig 7 1 ) needs to be transported to surface or left behind in the bottom of the well as will be discussed in Chap 8
