Cementing Program

Well cementing is a specialist area. While the main considerations
for writing a drilling program are discussed, ultimately it is important
to use the expertise of a cementing service company to design the opti-
mum cement job. The objective of this section is to help formulate
ideas for cement job design and to ensure that the most important fac-
tors are covered. Further reading is recommended; in particular, the
book Well Cementing, written by Erik B. Nelson and published by
Schlumberger Educational Services (order number SMP-7031), is
probably the best practical reference work on the subject.
Normally the drilling program will contain only outlined details on
the cement job. Many specific details must be sent out shortly before
the job as a supplement or amendment to the drilling program.
Information not available before spud, but which will have impact on
the casing and cementing programs, includes:

information from drilling (e.g., actual lithologies encountered,
hole problems, and directional profile)
logging (e.g., enlarged hole and formations requiring special
considerations)
