Well "X-01" is a slant (J-Type) directional well and will be subjected to appropriate technically qualified drilling casing planning in order prevent problems such as burst, collapse, tension that can cause increased internal external pressure loads experienced by the casing. The methodology used this research document study quantitative analysis using Drilling Software taking into account load...

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...

Corrosion monitoring and early detection of pits and wall thinning for casing pipes are considerably important to gas and petroleum industries since the frequently occurring corrosion at the internal or external parts of those steel casing pipes used in underground gas storage or oil fields causes production and environmental protection problems. In this paper, a new version of the direct curre...

Ultra-deep oil and gas wells have become a new development trend in onshore exploitation. However, wellbore casing is with high failure risk due to the harsh environment. It essential evaluate reliability of casing. This paper assesses operational using data statistics numerical simulation. Firstly, theoretical model for analysis established, variables are determined, including rock mechanics, ...

Design and manufacturing technology of high pressure multistage pumps which are commonly utilized in oil and gas industries, used to be imported from foreign companies. Due to international sanctions against I. R. Iran, it started to be designed and launched domestically. Nowadays all production lines including design, manufacturing and testing of these pumps have been performed by Iranian expe...

The most prominent aspect of multiphase flow is the variation in the physical distribution of the phases in the flow conduit known as the flow pattern. Several different flow patterns can exist under different flow conditions which have significant effects on liquid holdup, pressure gradient and heat transfer. Gas-liquid two-phase flow in an annulus can be found in a variety of practical situat...

to reduce peat while increasing the water holding capacity (whc) of casing soil in button mushroom production an experiment was conducted in 2006 with three hydrogel treatments of: t0= casing soil with no hydrogel, as control, t1= casing soil + 10% hydrogel (v/v), and t2= casing soil + 20% hydrogel (v/v) with three replicates in a completely randomized design. results indicated that treatment 1...
