For years, drilling engineers have been faced with the challenge of drilling wells through
naturally fractured reservoirs that are present around the world. During drilling, the pressure …

Lost circulation is the main reason for increased non-production time (NPT) and drilling
operation costs in fractured formations. Faced with such complex events, wellbore …

Fiber materials have become an attractive choice for lost circulation material (LCM)
applications recently. While there has been significant attention on the size, aspect ratio, and …

Lost circulation during drilling operations is a major problem owing to the prolonged non-
productive time, especially in naturally fractured reservoirs. Incorporating granular lost …

Moderate to severe loss circulation problem encountered while drilling is a major economic
burden that increases the total well construction cost dramatically in some cases. This study …

The novel resin composition described in this paper has been designed to treat moderate to
severe losses. The resin composition comprises an epoxy resin and a chemical activator …

Steelmaking industrial waste, that is, silicomanganese fume (SMF), is one of the byproducts
obtained during the steelmaking process in an electric submerged arc furnace at 1500° C …

Lost circulation has become one of the major technical risks while drilling a well. It can also
represent much higher costs when unplanned rig time adds up to the well's total cost. A new …

To combat the problem of lost circulation during drilling, lost circulation materials (LCM)
have most commonly been added to the drilling fluid to seal the fractures and recover the …

Lost circulation is one of the prevalent issues in drilling operations. It holds a negative
impact on the oil and gas industry as it is a major source of non-productive time (NPT) …
