“…Arabloo et al [10] employed a charged coupled device camera and a light microscope to investigate the size distribution of CGAs of different aphronized drilling fluids. Alizadeh and Khamehchi [17][18][19][20][21][22][23][24] proposed a new and novel diffusion model for CGA fluids including the mass transfer, which is described as diffusional phenomena in the presence of convective motion. In this model the mass transfer resistance for all phases and interfaces of a bubble was taken into account.…”

Today, the drilling operators use the Colloidal Gas Aphron (CGA) fluids as a part of drilling fluids in their operations to reduce formation damages in low-pressure, mature or depleted reservoirs. In this paper, a Taguchi design of experiment (DOE) has been designed to analyse the effect of salinity, polymer and surfactant types and concentration on the stability of CGA fluids. Poly Anionic Cellulose (PacR) and Xanthan Gum (XG) polymers are employed as viscosifier; Hexadecyl Trimethyl Ammonium Bromide (HTAB) and Sodium Dodecyl Benzene Sulphonate (SDBS) have been also utilized as aphronizer. Moreover, bubble size distributions, rheological and filtration properties of aphronized fluids are investigated. According to the results, the polymer type has the highest effect, whereas the surfactant type has the lowest effect on the stability of CGA drilling fluid. It was also observed that increasing salinity in CGA fluid reduces the stability. Finally, it should be noted that the micro-bubbles generated with HTAB surfactant in an electrolyte system, are more stable than SDBS surfactant.

“…Plastic viscosity (PV), yield point (YP) and gel strength were measure using FANN viscometer [13]. For gel strength testing, two readings were taken, gel strength at 10 seconds and gel strength after 10 minutes [14]. All the rheological properties were measured at all test temperatures (30ºC-93ºC) and at all concentrations (1% -4%) of the plant sample.…”

This paper aimed at improving the water-based drilling mud using Moringa oleifera (M. Oleifera) plant leaves. The rheological properties (plastic viscosity (PV), yield point (YP), and gel strength) of the mud were measured using standard procedures. The mud weight was not affected by M. oleifera concentration (10.03-10.63 pounds per gallon (ppg)). pH of the formulated mud decreased by 28% with increasing concentration of the M. oleifera leaves. The highest PV (33cP) was recorded by mud with 1% M. oleifera leaves at 50ºC while the least value (22cP) was given by control mud at 70ºC temperature. Highest YP (57 1b/100ft 2 ) was recorded by mud sample with 4% concentration of M. oleifera leaves while 1% gave the lowest YP value of 91b/100ft2 at 30ºC and Original Research Article

Recently, Colloidal Gas Aphron fluids, which includes micro-bubbles in a based fluid, have been successfully employed in drilling depleted reservoirs or formations which had previously experienced huge fluid losses. Aphron bridging in the front of the porous media in near wellbore zone, reduces the formation damage and fluid depth of invasion into the formation. Although more experimental investigation is carried out on Aphron fluid filtration, a few modeling works were performed in the literature. In this work, the filtration theory approach is used to mathematically model the Aphron transport in porous medium. Several physical/chemical parameters including surfactant type, surfactant concentration, temperature, rock porosity and permeability, grain and bubble size, and pressure, were investigated. Results from the modeling suggest that retention of Aphrons could be adequately described by the filtration theory.
