... ABSTRACT This study aims at depicting the near surface extent of the Main Frontal Thrust (MFT) in a small segment (nearly 6 × 6 km area) in the Himalayan central seismic gap using a recently developed passive seismic technique ambient noise tomography (ANT). The chosen region is an alluvial...

... boundaries. The final one is called microscopic fracture toughness (MFT) and is an important parameter. In this paper, a new mechanical testing machine is developed to make clear MFT of mineral grains within rock, based on the mechanical testing machine in the field of metallurgical engineering. Then, MFT...

... Abstract There are three challenges facing scientists and engineers in mature fine tailings (MFT) treatment: fast solids/water separation, maximum water recovery, and consolidation of the final sediment. To date, polymeric flocculants have been widely used in the oil sands industry, alone...

..., accelerated dewatering, mature fine tailings (MFT) drying, and centrifuged MFT(3). This paper discusses the preliminary results of a recent pilot scale verification of the centrifuged MFT technology. Centrifugation of MFT as a concept was tested in 1991 in order to provide an upper limit to fluid fine...

ABSTRACT A variety of tailings handling technologies have been developed over the years to deal with the accumulated mature fine tailings (MFT) and to mitigate storage problems associated...

... and flotation. The potential for using CO2 as a substitute for gypsum was evident from high viscosities observed in CO2- saturated MFT4. Under normal circumstances, high MFT viscosity is essential for good CT production. In fact, one would need about 3000 ppm of gypsum in the MFT to match the viscosity produced...

... the tailings are treated, the sand rapidly settles out in the ponds, but the clays settle slowly to about a 30 wt% slurry to form what is called mature fine tails (MFT). The MFT is very difficult to reclaim geotechnically and tends to accumulate in the recycle water containment areas. Recently Suncor began...

... of the available fluid fine tailings, the net water lost to tailings per volume of bitumen production would be reduced from four to three. It could be possible to implement the CT process to deal with the accumulated mature fine tailings, or to create an MFT analogue with a thickener on the fluid fine tailings...

...Figure 3 Test data from the MFT used for fluid properties sensitivity analysis (oil rate and water cut presented at 1-min frequency; GOR presented at 30-min frequency for ease of analysis). ...

... as the existing plant capacities are increased and new plants presently in commissioning phases become operational. This CHWE process provides acceptable bitumen extraction efficiency; however, it disperses silt-clay size particles causing mature fine tailings (MFT) production and increases Na + concentration...

... (bbls/Mft), 2) stimulation fluid volume (bbls/gal), and proppant volume (bbls/mlbs). There were no indications of well location effects on the normalized well performance, ie. no evidence of inconsistencies in reservoir quality across area, as the best 30 producers by lateral foot were dispersed...

... assumptions were made: - Fallback coefficient (FF) =0.05 - True fluid density (pt) =0.150 psi/ft - Average velocity of liquid slug (Vat) = 1 Mft/min Well LL-1481 (Table 3) Pcso is calculated using equations given in Appendix A. In the equations for Pcso, it is necessary to calculate the tubing pressure when...

... early history formation pressures in these challenging borehole conditions using a very small sized formation tester combined with robust new operational planning, practices, and techniques. The Compact Repeat Formation Tester (MFT), of diameter approximately 2.4 inches, was deployed in memory mode...
