PAPER ABSTRACT.
LABORATORY STUDIES OF CHEMICALS FOR SAND CONSOLIDATION (SCON) IN THE NIGER DELTA FIELDS.
Sanding during petroleum production causes severe operational problems in the oil and gas industry. Several techniques have been used for sand production control in sandstone reservoirs. Consolidating materials, such as, crude oil coke and nickel plating have been used in the past by researchers. At present, chemical binders such as phenol resin, phenol–formaldehyde, epoxy, and furan or phenol–furfural provides cementation. This paper is centered on the laboratory studies of selected sand consolidating resins tested suitable for application in the Niger Delta oil fields. Considering the available resins for consolidation process, six types of chemical resins namely; Epoxy (A&B), Novalak Phenol–Formaldehyde, Furan Phenol Acrylic, Furan and Phenol resins were selected for studies. Three other locally made resins namely Rubber Latex, Evo-Stik and Polystyrene Gum were reviewed alongside for comparison and test for their applicability. Different core samples were made (Cured) using these resins and their hardening agents with sand sample obtained from a sand producing oil field in the Western Niger Delta. The core samples made were subjected to laboratory qualitative and quantitative analysis in order to obtain individual fluidity properties (permeability and porosity) under different overburden pressures from 500psi through 3500psi. Results from experimental data show that Epoxy A&B resins ranked best followed by Furan resin and then, the local resins. This was adjudged by the permeability and porosity of the core samples retained from original values after curing and measurements done at various overburden pressures.
