The article talks about the application of openhole horizontal gravel packing in extended-reach (ER) reservoir drilling. According to the author, most ER wells are openhole completions requiring sand management to guarantee interventionless production. The article states that a finite-element analysis (FEA) model of the steady-state pore fluid diffusion with stress was developed to evaluate the induced stresses on gravel in horizontal, openhole well configurations.

The article discusses the use of modeling technique to represents hydraulic fractures in the local grid refinement (LGR) of the simulation grid. It examines the impact of hydraulic fracturing to the change in the flow dynamics of a reservoir. It also highlights several factors of hydraulic fracturing in multilateral, multisegment well (MSW) which include motivation, fracture inflow and fracture discretization.

The article discusses the interaction between the coupling of hydraulic fractures and natural-fracture networks with the shale matrix. It examines the utilization of preshale technology to emphasize the combination of technologies in the reservoir and production modeling of shale assets. It highlights two groups of reservoir modeling such as explicit hydraulic-fracture (EHF) and stimulated reservoir volume (SRV).

The article discusses the true-vertical-depth (TVD) assurance method, a refined and validated tool to determine hydrocarbon-column height with aid of TVD-error-confidence model. This approach utilized 3 complementary elements including high-quality sag modelling capability, multiple comparable inclinations sensors in the same bottomhole assembly (BHA), and qualified high-resolution (HR) inclination data in real time. These approaches improved TVD uncertainty related to extended reach (ER) wells.

The article discusses research on the use of flowline and subsea systems in the developments in the Perdido field found underwater of the Gulf of Mexico. Some of the challenges faced by the researchers include the low reservoir energy, ultradeep water and marginal project economics. They initiated thermal/hydraulic studies as well as comprehensive fluid-sample analysis to examine the field.

The Upper Burgan is a multilayered reservoir in the Sabiriyah field of northern Kuwait, currently undergoing the initial phase of waterflood development. The reservoir is highly complex with respect to reservoir heterogeneity, connectivity, and structural compartimentalization. Early waterflood performance was too poor to achieve the targeted injection rates Detailed channel mapping enhanced the subsurface understanding to add value to the ongoing drilling, production, and injection plans. The integrated-reservoir-management (IRM) approach, with a strategy for depletion and pressure supped far each segment, increased short-term production and is sustaining the rates. The current and chart-term drilling plans target reservoir segments with higher pressures far well placement. [ABSTRACT FROM AUTHOR]

The article focuses on the real-time casing imager (RTCI), a fiber-optic-based technology designed for continuous high-resolution monitoring of casing deformation. According to the article, regular monitoring of casing derformation should be an essential part of the reservoir-surveillance program as reservoir compaction and other geological conditions can impart loads on casing, which can lead to loss of the well. The article also highlights a Bragg reflector or Bragg grating, which could be used for temperature and strain measurements.

The article provides a discussion about an optimized solid control used in improving formation strength of oil fields. It states that optimized solid particles, such as graphite and calcium carbonate (CaCO3), gives chances to drill the wells' depleted reservoirs. It also features an offshore operation where coarse shaker screens were utilized to allow the re-entering of relatively large particles to the well during the circulation.

The article focuses on the improvement of oil well and reservoir management with the use of swelling elastomers (SE). The theory behind this is that when contacting formation water, rubber elements will swell to seal off the annulus between the completion and the wellbore. It is noted that segmenting the well into different flow units is key to achieving improved oil recovery through well and reservoir management in a horizontal well.

The article talks about the modern testing process of reservoir drilling and completing. The article states that a test involves a pressure sensor of the right resolution and accuracy put in the right place and left for the right amount of time. Multiphase flowmetering and fast pressure/volume/temperature (PVT) analysis are two areas in which high technology is playing a major role.

The author expresses his opinion on the impact of imaging technologies in monitoring the overall oil reservoir performance. He says that reservoir monitoring is a fast-developing area of production technology that has the objectives of measuring, controlling, and predicting the performance of the reservoir as a complete system. He states that imaging technologies may include 4D seismic, microseismic, and surface deformation.

The article discusses the impact of fracturing treatments on well productivity in unconventional reservoirs wherein the production engineers understand the efficacy of well pressures, rates, and return-fluid composition.

The article discusses the significance of subsea processing for the oil and gas industry. It is inferred that subsea processing or treating the production flow at the seabed has opened vast opportunities to more-remote oil and gas reservoirs around the world. Likewise, it notes that subsea processing has continued to evolve into the future with project developments focusing on the use of gas/liquid separation and oil/water separation technologies.
