Abstract The paper deals with drilling fluid flow in a horizontal well during its drilling. As part of this work, rheological parameters water-based the addition polymers and foaming agent were used. Cuttings transport was studied at different degrees foam aeration. Besides, presents study effects flow, as rotation drill pipes on cuttings transport.

in this study, functional properties of red bean, chickpea, lentil and canellini bean were evaluated. our results revealed that beans had the highest emulsifying capacity. this property was minimum at the isoelectric point (about 4) among all samples which is in concistent with their solubility curves. salt concentration of 0.5 m did not have a significant influence on emulsifying capacity but ...

As a result of the ambiguity and complexity surrounding anaerobic digester foaming, efforts have been made by various researchers to understand the process of anaerobic digester foaming so as to proffer a solution that can be universally applied rather than site specific. All attempts ranging from experimental analysis to comparative review of other process has not fully explained the condition...

Tomat merupakan buah yang mengandung kadar air cukup tinggi dapat menyebabkan proses pembusukan. Menjadikan tomat ke bentuk bubuk melalui pengeringan adalah salah satu cara untuk mengawetkan tomat. Penelitian ini bertujuan mengetahui karakteristik serta pengaruh foaming agent tween 80 pada dengan variasi laju udara fan, waktu dan temperatur. Metode digunakan metode tray dryer. menggunakan varia...

The main factor affecting the economics of foam-assisted water alternative gas (FAWAG) process is the loss of foaming agent by adsorption onto reservoir rocks. In this study, the effects of phases, surfactant concentration, salinity, adsorbents, and sacrificial agent on adsorption density were investigated by special adsorption experiments. Moreover, a series of FAWAG tests were performed to ex...
