The oil (diluted bitumen)–water separation efficiency at steam-assisted gravity drainage (SAGD) process conditions has been evaluated in a laboratory environment by using custom-built batch setup, SAGD field fluids and commercial gas condensate as diluent. key parameters investigated are solvent amount, shear conditions, water-to-oil ratio, the presence wettability of fine solids. results demon...

OBJECTIVE Assess the performance of self-expanding venous cannulas for routine use in open-heart surgery. METHODS Prospective study in 100 unselected consecutive patients undergoing open-heart surgery with either remote or central smart venous cannulation. RESULTS The study focuses on the 76 consecutive adult patients (mean age 59.2+/-17.3 years; 60 males, 16 females) undergoing surgical pr...

This investigation presents the effect of various parameters on foam stability and its rheological properties. The underlying idea of this experiment is generating of drilling foam with uniform bubbles. The main problem of foam using is controlling its stability during field application. The most important parameters which cause Instability in foam are gravity drainage, gas diffusion and bu...

We present ‘bAd Calculator’, a new software developed in Visual Basic programme which can be applied for analyses of various drainage basin parameters, directional aspects, etc. The graphical user interface of bAd Calculator can be used for several applications such as determination of bearing and azimuth of linear features and their representation in rose diagram. Various drainage basin parame...

Shortand long-term ground deformation at the cyclic steam stimulation (CSS) enhanced oil recovery sites in the Cold Lake region of Alberta, Canada, was measured with RADARSAT-2 differential interferometric synthetic aperture radar (DInSAR) during 2011–2016. The interferometric processing of 84 highresolution spotlight images revealed extensive short-term ground uplift and subsidence greater tha...

Summary We evaluated the clinical outcomes for ophthalmic endoscope-assisted vitrectomy in consecutive patients with uncomplicated rhegmatogenous retinal detachment (RRD). The primary success rate was 98.4% (125/127) without performing a posterior drainage retinotomy or using perfluorocarbon liquids (PFCL) for subretinal fluid drainage. Purpose To investigate the clinical outcomes of endoscop...

Gravity drainage is the main mechanism which controls the oil recovery from fractured reservoirs in both gas-cap drive and gas injection processes. The liquid bridge formed between two adjacent matrix blocks is responsible for capillary continuity phenomenon. The accurate determination of gas-liquid interface profile of liquid bridge is crucial to predict fracture capillary pressure precisely. ...

As an option to improve the ultimate oil recovery factor of Rang Dong field, a feasibility study gas-assisted gravity drainage (GAGD) application was carried out for fractured basement reservoir with single-well Huff ‘n’ Puff pilot test applied on high water-cut producer. This paper aims provide in-depth understanding about such case study, which includes details candidate selection, gas inject...
