This study aimed to analyze the outcomes of stress intensity factor (KI) and new bond strength tests oil well cement (class H) with a water-to-cement ratio (w/c) 0.38. Mechanical properties paste, such as compressive flexural strengths, were tested qualified at 1, 7, 28 days curing. The relationship between elastic modulus axial strain using differential Vipulanandan p-q model for paste was obt...

The paper analyzes field data of the most effective geophysical methods to date monitor technical condition production casing using examples wells at Romashkinskoye oil in Tatarstan. results interpretation according a flaw detector together with caliper gauge are presented. significant intervals column subjected various stages corrosion have been identified and described, which allows us determ...

The industrial world is currently considering the adoption of Wireless Sensor Networks (WSN) for industrial process and control applications. However, when using wireless sensor networks in such application scenarios, network performance, reliability, and robustness must be ensured with high degrees of precision. In this paper we study an outdoor deployment of a wireless sensor network in an oi...

Abstract During hydraulic fracturing, there has been little research on casing tensile stress distribution from the tilting area to horizontal in whole string. In order study bending sections during a three-dimensional finite element mechanical analysis model of casing–cement–formation was established. The showed that: When cement missing, decreased with situ difference increasing, and increase...

Fish sausage is ground fish meat, or a mixture primarily of ground fish with ground pork, together with vegetable oil, permissible preservatives, seasoning and starch. It is packed in a casing and processed. It is a semi-processed food, the time and temperature of processing of the product being not sufficient o kill all micro organisms. Thermotolerant and spore-forming bacteria survive the pro...
