To investigate whether the fertilizers N, P or K individually affect plant growth, oil content and the gender of sweet gale, two trials, pot and field trials, were carried out at Orkney College UHI in Scotland. A pot trial was established with eight soils which were collected from different sweet gale trial sites in the north of Scotland. Although neither shoot yield nor oil concentration in sh...

In this paper, fuzzy switching control of the complete oil cycle of Shiraz solar power plant is presented. So far, in the literature, only modeling and control of the collectors’ field of a solar power plant, which is a part of the complete oil cycle, have been studied. According to various environmental conditions, input disturbances and design constraints in some components, changes of the oi...

Continuous increase in oil pricing is not only causing difficulties to consumer but the imbalance in demand and supply is impacting the producer and refineries also. Consumer may adjust the demand dynamically as per the price fluctuation but oil major cannot change the production so dynamically. The recommended solution is the latest technology which could optimize the production, meeting the i...

as observed in some oil and gas countries, upstream service contracts, for instance buy-back contract in iran, would provide an appropriate environment for the development of oil and gas fields. however, certain cases, such as common structures and reservoirs, deep sea oil fields or second and third generations of an oil field may require more attractive contractual mechanisms in the eyes of io...

Studies of the energy return on investment (EROI) for oil production generally rely on aggregated statistics for large regions or countries. In order to better understand the drivers of the energy productivity of oil production, we use a novel approach that applies a detailed field-level engineering model of oil and gas production to estimate energy requirements of drilling, producing, processi...

Controlled-source electromagnetic (CSEM) data are sensitive to the subsurface resistivity distribution, but 3D inversion results are ambiguous, and in-depth interpretation is challenging. Resolution and sensitivity analysis as well as the influence of noise on resolution have been used to quantify 3D inversion performance. Based on these numerical studies, a land-based CSEM survey was designed ...

Despite the increasing interest in CO2 foam flooding for enhanced oil recovery applications, it is challenging to have a successful field operation as the performance of the surfactant is often affected by the presence of crude oil and salinity of the water. It is also challenging to dispose of huge amounts of water associated with the field operation. Due to the incompatibility of the produced...

thyme (thymus vulgaris l.) is perennial aromatic shrub belonging to the mint family which has anti-spasmodic, antiseptic, carminative, anti-cough, sputum and antioxidant properties. in order to study the effects of drought stress and bio-fertilizer on plant growth, essential oil yield and constituents of thyme plant, an experiment was conducted in a split plot based on randomized complete block...
