... of elevated temperature up to 180°c on the rheological and thixotropic properties of the drilling fluid with Gum Arabic as a major additive. Results show that mud density, viscosity and yield point are largely affected at Elevated temperatures for lower concentration of gum Arabic at Elevated temperature...

...) and Gum Arabic were used as polymers. Water breakthrough time, oil recovery and mobility ratio results obtained from fourteen samples were recorded and compared with that obtained from using only brine. The permeabilities of core plug samples were estimated prior to and after polymer flooding by pressure...

..., and Gum Arabic were used in flooding an already obtained core samples and comparative analysis of this shows that starch yielded the highest recovery due to higher viscosity value as compared to Ewedu with the lowest mobility ratio to Gum Arabic. Finally, the concentration of Starch or Gum Arabic should...

... This work studies the effect of medium and high concentration of monovalent and divalent ions on different polymers (Xanthan gum, Guar gum, Imported Carob bean gum or called the Locust bean gum, locally sourced Carob bean gum and Gum Arabic) used in Enhanced oil recovery; this is to enable...

... of chemicals is a sure way of ensuring pollution prevention rather pollution control. Analysis carried on these polymers showed good rheology especially at higher concentrations. The displacement efficiency of Locust bean gum (LBG) and Gum arabic were evaluated using 0.2wt% and 0.5wt% in hard brine to recover...

... and the rate of flooding. This paper presents the results of polymer flooding of an unconsolidated porous media using the locally available Gum Arabic in its natural and Modified states. Commonly used polymers Xantham Gum and Hengfloc were also used for comparison. The effective flooding rate was established...

... on the rheological properties of the polymer solution. The rheological behaviour for different solutions of Guar gum and Gum Arabic containing different salt was evaluated to study the effect of nanoclay and other additives on the stability of these biopolymers. The viscosity of these polymer solutions was measured...

... an experimental study of ASP flooding. Four methods classified as A, B, C and D were studied. Method “A” involving the mixture of Sodium Hydroxide, Lauryl sulphate and Gum Arabic to form an ASP slug resulted to further oil recovery of 7.1% of the Initial Oil in Place(IOIP). Method “B” (Sodium Hydroxide Pre-flush...

... salts will result in a more efficient polymer flooding projects, which will invariably lead to a better oil recovery. Gum Arabic solutions containing different salts which are commonly found in reservoirs with high salinity were prepared and viscosity tests were carried out to determine how...

... sulphate slug was injected then followed by gum Arabic slug. For Scheme B, a slug consisting of a mixture of Sodium Dodecyl sulphate and gum Arabic was injected after water flooding. In Scheme C, the core was first soaked with Sodium Dodecyl sulphate and then flooded with gum Arabic. The result showed...

... Sulphate and Shell Enordet and polymer- gum Arabic and Xanthan gum. The result shows that the ASP slug of Xanthan gum with Shell Enordet 0242 and Lauryl Sulphate had the highest displacement efficiency of 71.23% and 49.51% respectively. The others ASP slug formulated with gum Arabic and Shell Enordet...

...-effects encountered in alkali-surfactant-polymer (ASP flooding) combination flooding. As part of the ongoing research on the use of Gum Arabic as a polymer in chemical flooding in Nigeria, this paper investigates the effect of heavy oil viscosity on oil recovery during SP flooding. Improved oil recovery...

.../Polymer slugs formulated with two different surfactants: an anionic and a non-ionic surfactant named Lauryl sulphate (Sodium Dodecyl sulphate, SDS) and Tween 80 (Polysorbate 80), respectively. The alkali employed was caustic soda (Sodium Hydroxide), and the polymer used here was Gum Arabic. Gum Arabic...
