چکیده

the design of cement slurry for horizontal wellbores is challenging as it must present very high quality cement slurry properties e.g. zero free water, less than 50 cc api fluid loss value, appropriate rheology and yield point for effective displacement, adequate compressive strength, which is critical for lightweight slurries, and finally stable cement column behind casing. the main objective of these requirements is to provide unique cement sheath in the upper side of annulus as well as the lower side and to guarantee complete zonal isolation. these requisite conditions could be rarely met especially when lightweight cement is needed. four cement recipes were made and named as ripi-1 through ripi-4 representing standard slurry with a density of 118 pounds per cubic feet (pcf), traditional lightweight slurry with a density of 90 pcf, lightweight slurry with engineered psd and nanoparticles in a liquid form, and finally another type of psd and nanopowder respectively. these slurries were tested at the temperature and pressure of iranian balal, soroush, and siri oilfields and finally were compared with those slurries previously used in the oilfields. according to the results, reductions in yield point up to 84% and in fluid loss value up to 44% were recorded by the recipes. moreover, an increase in compressive strength up to 82% was measured and the maximum strength of 2500 psi was obtained for slurry ripi-4. all the slurries designed showed adequate stability. however, significant improvements were achieved by slurries ripi-3 and ripi-4 with engineered psd and nanoparticles.

language learning strategies and vocabulary size of iranian efl learners

learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...

Application of the PAMONO-Sensor for Quantification of Microvesicles and Determination of Nano-Particle Size Distribution

The PAMONO-sensor (plasmon assisted microscopy of nano-objects) demonstrated an ability to detect and quantify individual viruses and virus-like particles. However, another group of biological vesicles-microvesicles (100-1000 nm)-also attracts growing interest as biomarkers of different pathologies and needs development of novel techniques for characterization. This work shows the applicability...

Consecutive Application of Organic Matter and Sodicity on Secondary Particle Size Distribution

This study investigated the effect of rate and type of organic matter, and consecutive application of sodium on secondary particle size distribution. At first, a cropland soil was treated with two organic matter (manure and straw stubble) at different rates of 0%, 1% and 5%, with three types replicates during 4 months. Subsequently, four levels of SAR (0, 1, 10 and 30) were added to the pretrea...
