The high solubility of the invaded gas in oil-based drilling fluids and the heat transfer
between annulus fluids and the surrounding formation make the accurate prediction and …

As the oil-based drilling mud is widely used in the development of oil and gas in deep water,
how to model gas intrusion in the oil-based drilling mud accurately becomes a key issue for …

The study of the interaction between the formation gas and the drilling fluid during offshore
operations as well as in HPHT environment is essential to safely and economically drill the …

How carbon dioxide dissolves in drilling fluids is essential information for well control
simulators and for monitoring on drilling overflow early on. We utilized a single degassing …

Abstract Knowledge of methane dissolution behavior in drilling mud is of major importance
to early kick detection and well control operation in oil and gas drilling industry. In this work …

Absorption mass transfer coefficients (kla) of methane into two widely used drilling fluids
base oils-internal olefins and diesel were determined at elevated pressure. A laboratory …

Oilfield exploration in extreme areas represents additional requirements for drilling-fluid
performance and hydraulic models for well control. In general, there is little knowledge about …

Well construction is especially complex in deep and ultra-deep water, where large Brazilian
oil and gas reserves are located, demanding the use of synthetic-based drilling fluids, which …

An experimental apparatus has been developed to measure the CO 2 solubility in water,
brines, polymer solutions, white oil and drilling fluids using the sample analysis method. The …

For efficient and safe well operations it is important to understand the behaviour of gas influx
in petroleum fluids and the impact of relevant temperature and pressure changes in the well …
