Abstract In the present study, high surface area boehmite nanopowder was recovered from aluminum cans waste. The sodium aluminate solution first prepared by dissolving in NaOH and then, H 2 O added to precipitate boehmite. characterized means of X-ray diffraction (XRD), transmission electron microscopy (TEM) N adsorption–desorption techniques. thermal stability sample investigated using thermog...

A modelling effort was made to try to predict the life of downhole tubes or casings, synthetically considering the effect of service influencing factors on corrosion rate. Based on the discussed corrosion mechanism and corrosion processes of downhole tubes, a mathematic model was established. For downhole tubes, the influencing factors are environmental parameters and stress, which vary with se...

Oilfield Review Winter 2014/2015: 26, no. 4. Copyright © 2015 Schlumberger. FMI is a mark of Schlumberger. Sediments undergo several modifications to become the source rocks, reservoirs and seals that generate and contain petroleum reserves. The changes that occur between deposition and lithification, collectively known as diagenesis, include the processes of compaction, cementation, dissolutio...

Produced water (PW) during oil and gas production operations contains various hazardous substances including heavy metals (HM) with adverse impact on the environment. Disposal of PW interferes environmental sustainability, making treatment obligatory prior to discharge into Among previously available treatments PW, environmentally sustainable methods using low-pore space bio-adsorbents require ...

The Bozhong oilfield (Hereinafter referred to as BZ oilfield) is a typical representative of complex fluvial reservoirs in the Bohai Sea, located southern with an average porosity 30.3% and permeability 643 × 10-3 μm2, belonging medium high reservoir, reservoir has good connectivity, underground crude oil viscosity 5 mPa·s. There are many plane fault blocks, longitudinal well section long, so o...

The oil company holds the investment opportunity to develop a delineated oilfield. The investment plan must be presented until a specific date or the oilfield rights return to the government. The firm considers a set of mutually exclusive alternatives of scale to exploit the oilfield. Larger scale means faster exploitation – increasing the present value of revenues, but also higher investment c...

With the development of mobile technology, especially the development of 3G and mobile IP, the computational capacity of handsets is becoming more and more powerful, which provides a new method to solve the difficulties encountered in real time GIS accessing caused by the characteristics of mobility and remoteness of fieldwork in oilfield. On the basis of studying in-depth on the technologies o...

The compatibility of the dimensions polymer molecular aggregates and pore throat reservoir were studied. W section Tuha oilfield was study area polymers produced by Daqing Refining Chemical Company used. permeability limit molecules with different masses concentrations, matching relationship between dimension obtained experiments. results research are important for development implementation a ...
