Investigating the application of reactive polymers in fluid loss control
Lost circulation is the loss of drilling fluid from the borehole into a formation. It occurs when drilling into fractured, cavernous, vuggy and highly permeable formation (Hashmat et al. 2016; Al-saba Mortadha et al. 2014; Bugbee 1953) and can
High fluid loss acid soluble lost circulation material and spotting pill comprising the lost circulation material. The spotting pill preferably is weighted to a density substantially the same as the drilling fluid used to treat the formation.
WO2003048266A1 - Acid soluble, high fluid loss pill for lost circulation
High Fluid loss acid soluble lost circulation material and spotting pill comprising the lost circulation material. The spotting pill preferably is weighted to a density substantially the same as the drilling fluid used to treat the formation.
In a petroleum drilling operation, if the loss of circulation could not be solved using lost circulation materials, usually cementing into the loss zone may be the solution. However, cementing the loss zone may not be the best solution in geothe

- Are activated carbon-based processes a viable alternative to urban wastewater treatment?
- Activated carbon-based processes and ozonation are so far the most viable advanced treatment options for enhanced removal of organic microcontaminants of emerging concern from urban wastewaters. This is evidenced by their increasing full-scale implementation in urban WWTPs in Europe, mainly in Switzerland and Germany.
- Can China's sewage treatment industry practice a low-carbon development path?
- Under the “double carbon” strategic goal, China's sewage treatment industry must practice the low-carbon development path. Wastewater treatment does not only consume high energy but also generates a lot of carbon dioxide (Xi et al., 2025).
- Is there a sustainable 'zero-carbon' municipal wastewater treatment plant in China?
- This report aims to construct a sustainable ‘zero-carbon’ municipal wastewater treatment plant (WWTP) in China while concurrently emphasizing the recovery and utilization of organic energy, mainly organic matter.
- Can activated carbon adsorption be used with a good quality wastewater?
- Experimental data modelled with the Freundlich isotherm. Since the activated carbon demand to achieve the desired removal of target microcontaminants highly depends on wastewater DOC content, adsorption is recommended to be used with a good quality wastewater (ideally DOC < 10 mgC/L) which will favor a good performance-dose balance [38, 47].
