Abstract Drilling reservoir section in the oilfield located in Far North region is challenged with high risks of mud losses ranging from relatively minor losses to severe lost circulation. Numerous attempts to cure losses with traditional methods have been inefficient and unsuccessful.

Drilling waste also comprises used drill mud that has lost its technical properties. 3.1. Composition and discharges. The major components of drill muds are a liquid (water, oil, or another organic fluid) and a weighting material (typically barite, BaSO 4). Various additives are used to improve the technical performance of the mud.

The mud is delivered at a constant flow, pressure and temperature ensuring that the hydrocarbon analysis results in improved time depth precision and with improved gas ratio analysis. Applications It is an essential service to deliver reliable gas data during managed pressure drilling operations.

Hazardous substances cause 74,000 work-related deaths in EU countries each year. This indicates that more people die from dangerous substances than from workplace incidents. Caustic soda is one of the hazardous substances. A significant number of employees are away from work due to caustic soda skin burns, which can take weeks or months to heal.

The success of drilling operations is heavily dependent on the drilling fluid. Drilling fluids cool down and lubricate the drill bit, remove cuttings, prevent formation damage, suspend cuttings and also cake off the permeable formation, thus retarding the passage of fluid into the formation. Typical micro or macro sized loss circulation materials (LCM) show limited success, especially in ...

An oil based mud is a drilling fluid that has oil as its continuous phase and an all-oil filtrate. "Oil-based mud" usually refers to a mud that has 1-5% by volume water, while an invert mud has 5-50% by volume water. "Invert muds," or invert emulsions, refers to a water-in-oil emulsion with water droplets dispersed in the continuous ...

They are set in series for the active mud system. On most offshore rigs, pits are constructed into the drilling vessel and are larger, holding up to 1000 barrels. Circular pits are used at mixing plants and on some drilling rigs to improve mixing efficiency and reduce dead spots that allow settling.

drilling mud that exits to the surface. 1. If the drill bit is in direct contact with the gas bearing strata, this violent contact creates a large amount of rock dust which is then infused with gases and suspended into the drilling mud. 2. The mud may also contain gas impregnated rock particles: some smaller than 0.5mm, others larger than 1mm.

Drilling fluid is usually a mixture of water, clay, weighting material (barite) and chemicals. A variety of mud are now widely used (i.e. oil base, invert oil emulsion). Figure 4 A complete rig circulating system with rig itself. The mud must be mixed and conditioned in the mud pits, and then circulated by large pumps i.e. sludge pumps (Figure 3).

The process of evaluating the options and outcomes of using different mud weights in MPD can not only lead to the best drilling solution for the section, but can also be used as a discussion tool between the drilling team and the subsurface team, to help elucidate the most likely risks to the operation and thereby mitigate those risks in the most appropriate way.

Rotary applications soon confirmed that drilling mud density improved the borehole stability and was fundamental for the hydraulic control of the well. In the 1920s the use of regulating mud density by barite became standard, and in the 1930s bentonite was identified as the most convenient viscosizing material.
