“…16 Bureau compared three different EoS models (PR, SRK, Elliott-Suresh-Donohue [ESD]) in the prediction of bubble point pressure of methane/ester mixture and recommended the ESD equation with BIP = 0 to best describe the phase behavior of methane/ester binary system. 17 Kim used PR model to calculate the thermodynamic properties of methane/ester emulsion mixture according to the experimental results under high temperature and high pressure conditions. 18 However the majority of these studies are conducted with base oils or emulsions, only a very few cases regarding muds are presented in the literature.…”

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, methane solubility experiments in water‐based and oil‐based muds were conducted over wide ranges of temperature and pressure conditions. The influences of mud compositions and methane phases were investigated accordingly. It is found that methane solubility in water‐based mud is minimal and can be ignored. The data in oil‐based mud were analyzed using different equation of state and mixing rules. Our results show that the combination of our novel binary interaction parameter equations, Peng‐Robinson equation, and van der Waals2 mixing rule provides a very good representation of our data as well as those available in the literature. With the proposed model, the annulus methane solubility profile of a deepwater well in South China Sea was predicted, which provides a better understanding of the annulus flow behavior and further improve the safety of drilling operation.

“…Bureau et al [9] performed a comprehensive study on the interaction between drilling fluid (ester cut mixture with and without water) and reservoir fluid (synthetic oil whose base is the light fraction of a crude oil). Results were also reported for methane solubility in two heavy ester systems and two mixtures containing toluene.…”

TX 75083-3836, U.S.A., fax 01-972-952-9435. AbstractMore than 90% of Brazilian oil and gas reserves lie in offshore fields and over 60% of the total reserves are located in deep and ultradeep waters. Some of the important technical problems associated with deep and ultradeep water drilling involve: i) low formation fracture gradients; ii) long choke lines; and iii) low temperatures at the mud line. The well control planning and strategy for drilling exploratory and development wells in those fields should address those technical drawbacks in order to achieve the safety requirements in a cost-effective scenario.The better understanding of gas solubility in synthetic based drilling fluids plays a fundamental role in terms of preventive (kick detection) and corrective (kick circulation out of the hole) well control practices.The present work involves PVT characterization of two organic liquids (n-paraffin and ester) currently applied in drilling fluid systems for deep and ultradeep water drilling, in Campos Basin (Rio de Janeiro, Brazil). The measurement of thermodynamical properties of the methane-liquid mixtures, such as bubble point pressure, solubility, formation volume factor of oil, formation volume factor of gas and liquid density, were performed for 158 o F and 194 o F temperatures. The measurements were conducted in two different apparatuses: an Hg system and an Hg-free PVT system. The results showed that the correct accounting of formation gas solubility in downhole conditions and during the kick circulation is a very important issue for safely drill deep and ultradeep water wells.
