The harsh downhole conditions of high pressure and high temperature (HPHT) encountered
in geothermal wells make the drilling operation challenging. Drilling in such environments …

Research progress of self-healing hydrogels based on both reversible covalent and
reversible non-covalent bonds are systematically reviewed. The preparation methods …

Lost circulation will inevitably increase non-productive time (NPT) and well cost. The
application of high-efficiency lost circulation materials (LCMs) plays an indispensable role in …

This research presents a comprehensive review of lost circulation and wellbore instability
challenges in geothermal drilling, complemented by an original case study demonstrating …

Ultraviolet (UV)-curable thermoset shape memory polymers (TSMPs) with high recovery
stress but mild glass transition temperature (T g) are highly desired for 3D/4D printing …

Here we report an intrinsically flame-retardant high-temperature shape memory
photopolymer (HTSMP) with ultrahigh glass transition temperature (T g) of 280° C and …

Geothermal energy is the thermal energy stored within earth. In other words, geothermal
energy is the only alternative source of energy independent of the climate. This makes …

One of the most challenging issues during drilling operations is lost circulation, which can
cause several problems that could lead to increasing the non-productive time (NPT) and …

This paper studies the rheology and annular flow of a smart lost circulation material (LCM) at
160° C, using a high-temperature flow loop. The smart LCM is a shape memory polymer …

Geothermal formations often contain extensive fracture networks. These fracture networks
contribute to the significant loss of drilling fluids during geothermal drilling. Multiple loss …
