Enhanced hydrophobically modified polyacrylamide gel for lost circulation treatment in high temperature drilling
1/3/2021 · Loss circulation was one of the most serious issues throughout the oil and gas drilling operations, leading to many severe drilling problems, such as, borehole instability, formation damage, differential sticking, etc., even loss of the well. Lo
Loss circulation in drilling and well construction: The significance of applications of crosslinked polymers in wellbore
1/2/2020 · Loss circulation is one of the major concerns in drilling and well construction. The uncontrolled flow of fluids into formation while drilling or primary cementing lead to substantial non-productive time (NPT). The methods of wellbore
A review on geothermal wells: Well integrity issues
9/9/2020 · Mansour et al. (2017) introduced a novel lost circulation material of a thermoset shape memory polymer, 1 which activates when exposed to loss zone temperature (Smart LCM). They conducted experiments to investigate the efficiency of the smart LC
Performance and application of high-strength water-swellable material for reducing lost circulation under high temperature
1/6/2020 · The present polymeric system as a loss circulation material has been widely used in plugging process (Ahmed et al., 2019). However, due to the different lithology of strata, causes and types of leakage in different regions ( Zheng et al., 2003
US10081756B1 – Loss circulation material composition comprising oil-swellable and desolvated polymer gels
An oil-swellable gel lost circulation material (LCM) formed from an elastomeric polymer and a crosslinker amine is provided. The LCM may include gel pieces cut from gel strands formed from an elastomeric polymer and a crosslinker amine. The
Polyacrylamide Market Size and Share | Industry Statistics – 2027
Polyacrylamide Market size was around USD 5 billion in 2020 and is estimated to exhibit a CAGR of over 7% from 2021 to 2027. Rapidly growing water treatment industry across the globe projected to drive the industry growth during the forecast
New circulation sub improves lost circulation mitigation | Offshore
4/11/2015 · Fluid loss is a familiar problem with a known solution: pumping lost-circulation material (LCM) into the formation. The challenge, then, lies in determining the precise formulation and placement of LCM needed to restore circulation.
(PDF) Experimental Investigation on Plugging Behavior of Granular Lost Circulation Materials in Fractured Thief Zone
17/9/2015 · Lost circulation of drilling fluid occurs frequently when drilling in fractured formations. Granular lost circulation material (LCM) is still widely used as a cure to combat the circulation loss
Investigating the application of reactive polymers in fluid loss control
30/8/2019 · 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
Sealing fractures: Advances in lost circulation control treatments – ResearchGate
The second method is pumping the lost circulation material (LCM) to seal and plug the losses [11]. Nevertheless, these methods are time-consuming and very expensive [12].
