Abstract Proper selection of the drilling parameters and dynamic behavior is a critical factor in improving performance efficiency. Therefore, development an efficient artificial intelligence (AI) method to predict appropriate control for optimization. The AI approach presented this paper uses power optimized neural networks (ANNs) model non-linear, multi-input/output system. optimization was achieved by optimizing controllers (combined genetic algorithm (GA) pattern search (PS)) reach...
Abstract Most of drilling hole problems are attributed to wellbore stability issues which adversely cause excessive lost time and cost millions dollars. The past experiences in Kupal oilfield showed mud losses, kick flows, tight holes pipe stuck leading repeated reaming, fishing sidetracking. the drilling-associated this field occurred during 12 ¼-in. hole, is across non-reservoir Gachsaran formation (consisting anhydrite, gypsum marl with thin limestone layers). Mainly due lack required...
Integral cement sheaths are crucial for safe and economical hydrocarbon production throughout the well lifecycle. Cement additives tailor short- long-term properties various conditions to ensure integrity. Although exist, current trend in reducing carbon footprint motivates developing "greener" that environmentally friendly made from renewable sustainable sources such as cellulose nanocrystals (CNC). CNCs exhibit superior have shown significant impact on slurry, including increased degree of...
Abstract According to the field data, there are several methods reduce drilling cost of future wells. One these is optimization parameters obtain maximum rate penetration (ROP) in each bit run. Many affect ROP like hole cleaning (including drillstring rotation speed (N), weight on (WOB), floundering phenomena, mud rheology), tooth wear, formation hardness depth and kind formation), differential pressure (MW)), etc. Considering geology rock mechanical parameters, part well has different...
Nanofluids may be used for better cooling of drilling bits, especially poly crystalline diamond compact which are very temperature sensitive. The study on the modeling energy transport in nanofluids divided heat transfer into two portions—heat transferred by stationary particles and moving particles. authors studied each portion together. An equation thermal conductivity was developed based nanolayer thickness, Brownian Motion, size distribution nanoparticles. expression successfully...
Abstract Rock compressibility has many applications in the upstream petroleum industry, for example, reservoir material balance calculations and geomechanics, as related to possible formation compaction subsidence. When measurements on core are not available, empirical correlations may need be considered, derived specific fields. In study presented, suitability of log-based method evaluating rock is investigated, with aim deriving a suitable correlation Asmari carbonate, Southwest Iran. A...
Abstract Two phase flow applications in petroleum industry are so widespread. It is a fact that UBD precise bottomhole pressure maintenance ascertains success. hydraulics design, especially for inclined trajectories, real challenge. This greatly dependent on the drop annulus. through annulus an ambiguous area of study to evaluate pressure. correlations which most simulators based over predict and also make extrapolation risky. Although Mechanistic approaches increase frequency designing two...
Abstract Controlling lost circulation during drilling operations in a reservoir prone to fluid losses is typically remedied by cement squeezing or plug setting as the last resort. The aim being minimize stop and regain full returns at surface, maintain wellbore integrity. Different placement methods of plugs have been discussed detail literature, except for ‘level-off’ method, which can be effective curing complete loss cases. Following modeling calculations this its design execution...
Abstract Hydraulic fracturing is the process of inducing a highly conductive path from reservoir to wellbore, thus increasing productivity wells. The final success hydraulic greatly depends on candidate well selection. Accordingly, selecting proper crucial importance. This paper sets series criteria for assisting selection fracturing. IPR and correspondingly index variations after as case studies several wells in one Middle Eastern oil fields have been studied this work detail. can be used...
The problem of scale is very common in the process oil production at initial and final stages field development. Inorganic may precipitate from formation fluids various elements oilfield system extraction process. These scales, which collect under certain thermodynamic physical-technical conditions, cause a decrease equipment reliability productivity. article highlights main factors affecting evaluates effectiveness inhibitors. It noted that wells with periodic inhibition, it necessary to...
Hydraulic fracturing can be utilized to extract trapped hydrocarbon where integrated fracture networks do not exist for sufficient production. In this work, design parameters of a hydraulic acid tight carbonate reservoir in the Middle East were optimized. The effect optimized on production performance and rate was investigated. Using petrophysical well logs, formation integrity tests, core data Mechanical Earth Model (MEM) created, which resulted rock mechanical properties in-situ stresses....
Abstract The thermal conductivity coefficient of the reservoir formation rock-cement-casing combination is an important parameter affecting optimum circulation flow rate in open and closed-loop systems. Despite its importance, accurate value may not used modeling due to fact that either rock cement measured lab be accurately known, or effect casing conductivities on net ignored. Therefore, this work investigates a change heat energy, power performance (COP), at different rates. simulation...

Abstract Precise prediction of bottomhole circulating pressure (BHCP) is the major concern in designing stage an underbalanced drilling (UBD) operation. A successful UBD operation hinges tightly on accurate control downhole pressures. In order to predict gradient, complex two-phase flow correlations are employed and pattern defined. The problems arising from such methods significant errors relative nature a need for localization parameters or shift one correlation another case case. this...
