Due to the use of horizontal wells and hydraulic fracturing, commercial tight oil production from some sandy conglomerate reservoirs has been achieved. Since widely distributed gravels in matrix reservoir rocks are harder than matrix, rock mechanical response conglomerates under compression is highly heterogeneous. This increases complexity understanding fracturing behaviors reservoirs. Previou...

Bezoars are rare causes of gastrointestinal obstruction. Basically, they are of four types: trichobezoars, phytobezoars, pharmacobezoars, and lactobezoars. Some rare types of bezoars are also known. In this article a unique case of plastic bezoars is presented. We describe a girl aged 14 years who ingested large amounts of plastic material used for knitting chairs and charpoys.
