An experimental study on reshaping C110 deformed casing with spinning casing swage

Study on Measuring System of Casing Machine Based on PLC

According to the technology requirements of measurement for animal casing, in this paper, we use PLC and touch screen as the control core, the electromechanical integration design ideas to research the methods and principles for casing measure, and analyze the mechanical structures and mechanical characteristics of casing machine. As the control core, the programmable logic controller (PLC) ens...

ABC Analysis Behind Casing

Literature Survey on Cements for Remediation of Deformed Casing in Geothermal Wells

Brookhaven National Laboratory was requested to conduct a literature survey for the best available cement to use in the proposed casing patch as part of the Geothermal Drilling Organization (GDO) project on remediation of deformed casings. A total of 50 wells has been identified with deformed production casing in Unocal’s portion of The Geysers geothermal field. Reduced internal diameter and ca...

Production flush of Agaricus blazei on Brazilian casing layers

This study aimed to verify the biological efficiency and production flushes of Agaricus blazei strains on different casing layers during 90 cultivation days. Four casing layers were used: mixture of subsoil and charcoal (VCS), lime schist (LSC), São Paulo peat (SPP) and Santa Catarina peat (SCP); and two genetically distant A. blazei strains. The fungus was grown in composted substratum and, af...

Diagnosis method of casing damage based on BP neural network

One of the major problems faced by the oilfields in the middle time is casing damage. The neural network, the improvement BP as well as the three-layer feed forward neural network applied in damage diagnosis is a key way to prevent damage. The formations of the damage are corresponded to the input vector. Factors such as casing age limit, strata stress, soaking time are described as real Number...
