... are proposed for cumulative moles produced and for molecular weight of the C7+ fraction of the equilibrium gas. A new method for setting a more stringent constraint on the density of the liquid phase is proposed. Surprisingly, the presence of a straight line on the Hoffman, Crump, Hocott plot does...

... Hz from each amplitude, and lower values as amplitude was increased. Although high molecular weight HVFRs were utilized on the conductivity test, the results observed that the regained permeability was up to 110%. Finally, the promising results from the case study showed that using HVFRs could...

... in the past two years. FR materials have extremely high molecular weight; consequently, breakers are recommended to reduce polymer size and to mitigate potential damage to fracture conductivity, microfractures or secondary fractures, and the formation. A better understanding of the breaking mechanism of FRs...

... by mixing three different grades of HPAM (molecular weights of 500,000; 8,000,000; and 20,000,000) at polymer concentrations 0.09%, 0.05% and 0.03% wt. The shear viscosity and elasticity characteristics of test fluids were determined by performing shear viscosity and frequency sweep oscillatory measurements...

... class (P, N, and A) a constant ε parameter is used independent of molecular weight while the parameter m is assumed to increase linearly with molecular weight. The m and ε parameters of the individual component classes are combined into one value, representative of the whole carbon number fraction...

... control additives are high molecular weight sulfonated copolymers, generally comprising AMPS. The mechanism of action of these polymers has been studied recently and it was demonstrated that adsorption onto the cement surface is key to the achieve product performance. Unfortunately this adsorption yield...

.... A TBP distillation was performed on the Stock Tank Oil (STO) sample to obtain data for the molar concentration, molecular weight and density of the heavy components of the oil. The results are listed in Table 1 . The STO was recombined with a synthetic gas to obtain single phase reservoir oil...

..., C1-(C2)-C3/5-C6+ weight percents, GOR and downhole density are provided by the different techniques. Then, the model can predict the other fluid properties (such as molecular weight, FVF, API…) and propagate them along the well section thanks to the quantitative mud gas data alone. The quantitative...

A novel type of breaker system, derived from biological sources and displaying catalytic, polymer degrading activity similar to that of enzymes, was obtained and tested for its ability to reduce the viscosity and molecular weight of polymers used in hydraulic...

... as so it can move toward wells. This work proposes a correlation that can be used to predict or validate this property, based on the relationship between the maximum retrograde condensation, the molecular weight (MW) of the original composition and its gas oil ratio. A real case analysis is presented...
