Objective
- Knowledge development on sulfate stability of ultrafine cement and stability of light weight cement in presence of glass sphere extenders and basic research development on phenolic resins
- Formulation development: Elaboration of light weight cements blend formulation applicable for oil field well conditions with classical additives adjustment and recommendations on use of resin systems based on phenol group
- Operational test: field tests were performed with the new formulations and confirmed of a good workability of ultrafine cement blend without any problems of mixing and segregation.
The need for better economics, higher productivity,
environment protection and more efficient and safe
operations pushed the oil and gas industry towards the
development of novel drilling and completion
technologies, like slimhole, coiled tubing and high
precision plug operations. However, due to lack of
adequate cementing materials and placement techniques,
overall success and safety of cementing in these
operations is limited (30% for plugs) or cannot be
guaranteed (slimhole, coiled tubing).
Oil and gas companies have, therefore, a strong need to
extend current cementing technology in terms of
formulations and implementation techniques, in order to
take full advantage of the underlying benefits in costs
reduction, increased operations efficiency, productivity
and environmental impact. Manufactures and service
companies that perform cementations are forced to react
on new tendencies and developments, in order to be able
to provide materials and services with the necessary
properties and quality.
The objective of the project is to develop adequate
formulations for application of the aforementioned
technologies from 3 alternative chemical systems:
thermoset resins, mud cement systems and ultra fine
cements. For all 3 systems, selection and formulation
will be based on commercially viable materials having
favorable environmental characteristics relative to
toxicity, bioaccumulation and biodegradation. This
ensures the potential for application of project
deliverables in Denmark, Norway and the UK (North Sea
sectors) as well as world wide.
The final results will offer a range of technical
solutions in terms of cementing materials and procedures,
as well as rules for appropriate selection for given
operational conditions (depth, bottomhole temperature,
reservoir pressure, wellbore geometry). Results will
serve as a basis to create new standards and recommended
practices on cementing for the novel drilling
technologies. Significant progress is also expected in
remedial jobs in old wells and different areas of civil
and environmental engineering, like grouting and sealing
of waste/refuse dumps.
A balanced and complementary partnership was obtained,
involving 4 EU countries. It comprises
four big oil and gas companies that are directly
involved with the whole range of applications of the
novel drilling and completion technologies,
a major service company with advanced knowledge in
well servicing operations
a manufacturer strongly involved with
commercialization of high added value cementing products,
a research center and a university, both of world wide
reputation and expertise.
Besides expertise on formulation of drilling fluids,
cements and resins for severe application conditions, the
research center has develop analytical techniques (SEM,
NMR, X ray diffraction) to characterise structure
evolution in reactive materials. The university is
specialised in the experimental and theoretical
characterisation of the polymerisation reaction in
resins. The manufacturer is particularly active in the
research of innovating materials. The oil & gas
companies and the service company have advanced
complementary laboratory techniques to evaluate cement
quality (slurry characteristics, mechanical properties,
interface binding quality) under severe bottomhole
conditions.
The total budget is of 1.74 million ECU (126 manmonths)
and the duration of 28 months.
Companies of the project cover an important part of the
European oil and gas industry. Participation of the
service company will ensure efficient dissemination and
exploitation of results in Europe and world wide. It is
expected that results of this project will be available
for industrial use within 12 to 16 months after the
termination of the project.
