From previous case studies it is evident that in artificially lifted wells with either a bean pump (BP) or a progressive cavity pump (PCP) wear areas and associated corrosion are visible.
A PLT is a common logging tool which provides flow profile inside the wellbore only. This type of tool cannot provide the formation flow profiles as well as crossflow above-between-below perforated intervals.
The well is a vertical barefoot steam injector which was drilled in 2009. After drilling the well was completed with a 13 3/8” conductor, 9 5/8” surface casing and 7” intermediate casing.
It is important to have a good cement bond in the annulus, for example by using a multistage packer and having adequate centralization.
Drilling a zone with losses can lead to poor cement quality or in severe cases a total absence of cement behind the casing resulting in free pipe.
Insufficient sweep efficiency can lead to inadequate pressure support to neighboring wells.
Drilling through zones with total losses can lead to poor cement quality or in severe cases a total absence of cement behind the casing.
How to accurately measure the injection distribution profile behind the pipe. Some injection wells have been designed to inject via the tubing and the A annulus simultaneously.
The field is located in the south of the Sultanate of Oman.
Having an accurate knowledge of all casing accessories can be critical for operations such as perforating, window milling for sidetracking and casing milling for final abandonment.
In addition to the above listed advantages the EMDs tool can identify all completion and casing accessories in all pipes.
Ensuring a strong cement bond in the annulus is crucial and one of the effective methods to achieve this is by utilizing a multistage packer and ensuring proper centralization.
Drilling across a loss zone leads to a high probability of poor cement quality and free pipe. If there is a corrosive aquifer, the possibility of external corrosion is increased drastically.
It is important to have a good cement bond in the annulus across corrosive intervals. External coating on the pipe will lessen the risk of corrosion.
EMDs logging offers a cost-effective solution to determine the integrity status of the pipes without the requirement to pull the completion string.
Drilling through a loss zone leads to a high probability of poor cement quality and free pipe. If there is a corrosive aquifer, the possibility of external corrosion is increased drastically.
Integrity issues in steam injection wells can have unforeseen impact on adjacent production wells.
