Fundamental Experiments at Bottom Hole Temperature

Static Formation Temperature Prediction Based on Bottom Hole Temperature

Static formation temperature (SFT) is required to determine the thermophysical properties and production parameters in geothermal and oil reservoirs. However, it is not easy to determine SFT by both experimental and physical methods. In this paper, a mathematical approach to predicting SFT, based on a new model describing the relationship between bottom hole temperature (BHT) and shut-in time, ...

The Delta-hole Model at Finite Temperature *

The spectral function of pions interacting with a gas of nucleons and ∆ 33-resonances is investigated using the formalism of Thermo Field Dynamics. After a discussion of the zero ∆-width approximation at finite temperature, we take into account a constant width of the resonance. Apart from a full numerical calculation, we give analytical approximations to the pionic spectral function including ...

Bottom quark production cross section at fixed - target pp experiments

The cross section for bottom quark production at fixed-target energies is calculated for a wide range of beam momenta. A detailed analysis is given for the HERA-B experiment. We consider both the order α 3 s cross section and the resummation of soft gluon corrections in all orders of QCD perturbation theory. The inclusive transverse momentum and rapidity distributions, including resummation, fo...

Estimations of temperature at RHIC experiments

We have systematically estimated the possible temperatures T obtained at RHIC experiments by analyzing recent data on pt distributions provided by them. Different schemes of estimating T are used with special emphasis put on the concept of the possible indication of the temperature fluctuations seen in data. Our analysis suggests that we can choose a correct approach provided that data with lar...
