Hydrated shale formations often lead to severe drilling problems and may wellbore instability. These instabilities can result in issues such as bit balling, borehole collapse, formation damage, stuck pipe, low rates. Keeping these fundamental with mind, this study is aimed at designing a water-based fluid system for effective inhibition, ensuring enhanced stability efficiency. The designed mud comprises typical base along newly synthesized chitosan derivative chitosan-
Coalbed methane (CBM) reservoirs are naturally fractured formations with cleats surrounding the coal matrix. Analyzing and predicting CBM production performance is challenging because of complex fracture networks gas–water two-phase flow, along permeability porosity variation time-dependent desorption. During depletion, pressure decreases consequently stress increases, thereby decreasing cleat aperture permeability, while matrix shrinkage effect increases width permeability. The two effects...
Abstract Relative permeability is one of the most important properties in Coal bed methane/gas (CBM/CBG) fields for reliable reservoir modelling due to two-phase fluid flow. In CBM reservoirs, biggest challenges remains with high unreliability laboratory experimental relative data inherent nature coal. The scope this study define shape curve using available production analysis. interplay between water and gas within coal cleats affects mobility both gas. Sohagpur blocks India, there enough...
Summary Gas in the coal is found mainly form of adsorbed methane on surface micropores. Methane desorbs and diffuses from micropores to cleat systems; then, network delivers gas wellbore. The Langmuir isotherm empirically explains this phenomenon, a plot between pressure content (GC). generated laboratory, indicating how particular reservoir will desorb with reduction throughout production stage startup abandonment. This study aims validate laboratory-derived after few years field...
Summary Sucker rod pump (SRP) is the most popular form of artificial lift, used in one western assets Oil and Natural Gas Corporation (ONGC). It has been to produce both vertical deviated wells. In mature fields, frequent tubing sucker failures have witnessed SRP wells with mean time between (MTBF) as low 4–5 months, which resulted workover associated cost production loss. Rubbing bending rods below neutral point experiencing higher compressive load, a result loads caused by frictional...
Abstract Conventional laboratory core analysis tests on samples of two limestone reservoir rocks indicate that about 20 per cent PV is in dead-end pores. These (electric logging formation factor. mercury injection capillary pressure and miscible displacement) were carried out 3/4-in. diameter test plugs. Test results show a clear difference between these sandstone or homogeneous rock. Although the amount pore space can be only roughly estimated, presence such seems clearly indicated....
In coalbed methane (CBM) reservoirs, permeability changes dynamically throughout the life of reservoir as pressure depletes due to production. The dynamic variation coal mainly depends on combined effect effective stresses and matrix shrinkage caused by gas desorption. Under conditions pressure-dependent diffusivity in flow mechanism CBM reservoirs complicates solution two-phase equation. this study, authors present a new approach describe equation form that fully couples time-dependent...
Abstract This paper contains comparisons of calculated and observed flowing pressure profiles from geothermal wells located in the United States Philippines. Comparisons are included for tubular flow as well through casing-tubing annulus. Our comparison shows that flow, Orkiszewski correlation makes best prediction, whereas annular no clear-cut choice a can be made. Introduction The capability to accurately predict pressures producing steam-water mixtures under various operating conditions...
Abstract Modeling Underground Hydrogen (H 2 ) Storage (UHS) and Carbon dioxide (CO (UCS) in depleted oil gas reservoirs requires compositional simulation. Cubic Equation of State (EOS) models for the reservoir fluids have edge over other like GERG 2008 PC SAFT. Soave-Redlich-Kwong (SRK) EOS, a reliable choice needs Binary Interaction Parameters (BIPs) its efficient application to UHS UCS modeling. Existing correlations estimating BIPs SRK EOS may not be suitable binaries having long-chain...
