“…The increased resistance is achieved using nozzles, orifices, and helical channels on the base pipe. For more information on ICD, please refer to Al-Khelaiwi et al (2010) and Birchenko et al (2010). Figure 14 shows the boxplot of the dimensionless production temperature distribution of the two fracture system when L/(2R) = 0.4, ζ = 0.8, and σ h /�w� = 0.25 for three cases: no flow control (untreated), 50/50 flow split, and the optimal flow split.…”

“…To control the bottom water, prevent it from entering the wellbore too early, and maintain the horizontal well working normally, in the 1990s, the inflow control device (ICD) was designed for preventing the bottom water breakthrough. 3 Traditionally, the first generation of ICDs aimed to balance the pressure between the horizontal well and reservoir, maintain a uniform flow in the whole exploitation area, delay the inflow of water, and maximize oil and gas production. Subsequently, ICDs were installed inside the horizontal wellbore.…”

Horizontal well technology is an efficient method of oil and gas exploitation. The goal of increasing oil production and improving productivity can be achieved by increasing the contact area between the reservoir and the wellbore. The presence of bottom water cresting reduces the efficiency of oil and gas production significantly. Autonomous inflow control devices (AICDs) are widely used to delay the influx of water into the wellbore. Two kinds of AICDs are proposed to restrain the bottom water breakthrough during natural gas production. The fluid flows in the AICDs are simulated numerically. The pressure difference between the inlet and outlet is calculated to evaluate the ability of blocking the flow. A dual-inlet design can increase the flow rate of AICDs, thus enhancing the water blocking effect. Numerical simulations show that the devices can block water flowing into the wellbore effectively.

“…Therefore production, which is proportional to the pressure differential, preferentially occurs at the heel (Penmatcha et al 1999), increasing risk of unwanted gas and water coning, where the pressure gradient extends into the gas and water layers. Gas and water are then at risk of breaking into the well, causing their preferential production due to their lower viscosity relative to oil (Al-Khelaiwi et al 2010). This paper presents a risk based methodology using multiphase fluid modelling and Monte Carlo analysis, quantifying the horizontal well producing length beyond which drilling further does not substantially increase production rate.…”

“…High heel production rate accelerates oil depletion, causing early heel water production. Water is preferentially produced due to its lower viscosity, leaving unrecoverable oil at the toe (Al-Khelaiwi et al 2010). The project's discretised well model, based on Thomas et al (1998) and Ulaeto et al (2014), coupled reservoir inflow from each segment with cumulative axial flow.…”

Horizontal and multilateral oil and gas wells are used to maximise hydrocarbon recovery while reducing the required well count and associated costs. Presently, lateral lengths are designed using semi-quantitative methods. Guided by a desire to minimise the risk of poor well deliverability, the tendency is to design producing lengths longer than required, with the rationale that the well connects with sufficient hydrocarbon bearing reservoir to provide good deliverability. Drilling long producing lengths, however, is expensive and generates a higher risk of drilling and lifecycle (intervention and workover) problems. Furthermore, attempting to increase deliverability by extending the producing length encounters the law of diminishing returns as the flow becomes constrained by tubing friction loss. This paper seeks to quantify the optimal length for a horizontal well for a given range of reservoir conditions through multiphase fluid modelling and stochastic analysis. A discretised horizontal well model was created, which shows how changing the well length transforms the probability density function of the production rate for the well. A parametric case study was conducted, which demonstrates the evolution of the optimal well length and production rate with parameters including well diameter, fluid viscosity and well flowing bottomhole pressure. A simplified economic analysis illustrates the incremental change in discounted cash flow and quantified risk from drilling a longer well. The model also considered the influence of inflow control devices (ICDs) to adjust the inflow to match permeability and even-out inflows along the producing length, thus reducing the risk of gas and water coning, and improving hydrocarbon recovery.
