This work presents the construction solution and experimental results of a novel desorber for online drilling mud gas logging. The traditional desorbers use mechanical mixing of the liquid to stimulate transfer of hydrocarbons to the gaseous phase that is further analyzed. The presented approach is based on transfer of hydrocarbons from the liquid to the gas bubbles flowing through it and furth...

During well drilling in offshore conditions beyond the North of Arctic Circle, there are often problems associated with deviations rheological parameters mud as temperature changes. Mud upper part most cases is range up to 20 °C, whereas productive formation it 80 °C and more. For such conditions, necessary estimate influence on fluids, which done this paper. Compositions water-based hydrocarbo...

Abstract The research has shown successful application of ionic liquids (ILs) as drilling fluid additives for modifying the mud rheology. Ionic are tuneable solvents comprising hundreds combination various cations and anions. cationic portion mainly comprises a side alkyl chain which plays an important role in altering properties. This review focusses on finding impact length yield point, plast...

Analytic hierarchy process (AHP) is a utility theory based decision-making technique, which works on a premise that the decision-making of complex problems can be handled by structuring them into simple and comprehensible hierarchical structures. However, AHP involves human subjective evaluation, which introduces vagueness that necessitates the use of decision-making under uncertainty. The vagu...

Good agreement with field data has been obtained when using a commercial kick simulator to analyse a 56 bbl gas kick taken in a 59 deg deviated wellbore. Fast kick detection and reaction are necessary when drilling at high rates of penetration since high pump rates, necessary for hole cleaning and cuttings transport, imply that a gas influx may be rapidly circulated to surface. A simulated exam...

Shale is one of the rocks that often causes drilling problems because shale tends to swell or when in contact with mud filtrate, mainly water-based Water-base Mud (WBM). This study aims determine how performance Oil-base (OBM) based on Crude Coconut Oil (CCO) overcoming swelling problem. The methodology used consists simulation and cutting analysis X-Ray Diffraction (XRD) laboratory. series act...

The value rheology of drilling mud must be in accordance with the conditions wellbore that do not lead to occurrence problems at time drilling. One efforts improve is by adding Carboxymethyl Cellulose (CMC) which useful for increasing viscosity and binding water. This study aims identify effect on use CMC originating from jackfruit skin rheological properties mud. Jackfruit an underutilized org...
