“…It is well known that the two most commonly used techniques for a multi-stage hydraulic fracturing are the plug-and-perf technique and the ball-and-sleeve technique [31,32]. In this case, the most appropriate method is balland-sleeve.…”

This paper proposes a completion that can allow fracturing four zones in a single trip in the well called “Y” (for confidential reasons) of the field named “X” (for confidential reasons). The steps to design a well completion for multiple fracturing are first to select the best completion method then the required equipment and the materials that it is made of. After that, the completion schematic must be drawn by using Power Draw in this case, and the summary installation procedures explained. The data used to design the completion are the well trajectory, the reservoir data (including temperature, pressure and fluid properties), the production and injection strategy. The results suggest that multi-stage hydraulic fracturing can be done in a single trip by using the ball-and-sleeve method. Metallurgy and hydrogenated nitrile are sealing elementary constituent of chromium which are essential materials found in alloy with 13% of chromium.

The Minagish field in West Kuwait is a high potential field which poses several challenges in terms of hydrocarbon flow assurance through highly depleted tight carbonate intervals with uneven reservoir quality and curtailed mobility. These conditions have shifted the field development from vertical to horizontal wellbore completions. Achieving complete wellbore coverage is a challenge for any Matrix Acid treatment performed in a long openhole lateral with disparities in reservoir characteristics. The fluid will flow into the path of least resistance leaving large portions of the formation untreated. As a result, economic Acid treatment options dwindle significantly, thus reservoir stimulation results are not always optimum. A multistage acid stimulation technique using Integrated Dynamic Diversion (IDD) has been performed in a West Kuwait field well. The process uses active fluid energy to divert flow into a specific sweet point (high pressure point) in the lateral, which can pinpoint and precisely place acid treatment at the desired location. The process uses two self-directed fluid streams: one inside the pipe and one in the annulus. The process mixes the two fluids downhole with high energy to form a consistent controllable mixture. The technique includes pinpoint fluid jetting at the point of interest, followed by customized foamed HCL acid systems employed for improving individual stage targets in depleted reservoir. The IDD diversion shifts the acid treatment to unstimulated areas to create complex wormholes which increase reservoir contact volume and improve overall conductivity in the lateral. The kinetics and chemical diversion of the IDD methodology are highly critical to control fluid loss in depleted intervals and results in enhanced stimulation. The application of the IDD methodology is a fit-for-purpose solution to address the unique challenges of openhole operations, formation technical difficulties, high-stakes economics, and untapped high potential from intermittent reservoirs. By utilizing this application in one continuous operation, the use of chemical diverters, straddle packers and mechanical plugs for selective treatment in open hole is eliminated, making this multistage completion technology economical for these depleted wells. The paper presents results obtained after stimulating multiple zones along the lateral and describes the lessons learned in the implementation of this methodology. Going forward, the methods described, which can be considered a best practice for application to similar challenges in other fields. Proper candidate selection, optimum completion tools, and the fluid combination of in-situ gel-based diverter used to temporary plug the acid stimulated zone and foamed acid created an increase in the oil production of 430 BOPD.

In the current cost-constrained oil field environment, operators must complete their wells while minimizing capital expenditure. Operators respond to these challenges by utilizing customized diagnostic services and specialized tools in a single run to save on rig costs. Coiled Tubing (CT) deployed fiber- optics assist in taking Distributed Temperature Sensing (DTS) during acid stimulations to estimate fluid volume distribution in the horizontal openhole with a specialized jetting tool to create wormholes and complex microfractures. This paper discusses an acid stimulation process using dynamic fluid energy to divert flow into a specific sweet spot in the well to initiate and accurately pinpoint acid stimulation. The treatment efficiency was monitored and visualized in Real Time (RT) with CT-conveyed fiber-optic DTS. This acid stimulation process, named Integrated Dynamic Diversion (IDD), often uses two independent fluid streams: the acid phase down the treating string and other liquids or foamed fluid down the annulus. Two different fluids mix downhole with high energy to form a homogenous mixture. Pre-job DTS injection profile diagnostics identified a non-permeable zone, and the stimulation pumping schedule was adjusted accordingly. Using the IDD process, this was done in RT by changing the depths and increasing the number of stages across the non-permeable zone. Post-job injection profile DTS diagnostics confirmed an increase in injectivity across the non-permeable zone with a uniform injection across the entire openhole. This proved the value of combining RT CT with IDD using a dual pumping process and the specialized jetting tool. Post-job production results also indicate a sustainable production with an oil gain of +500 BOPD. Applying the IDD methodology with DTS services is the most appropriate solution to address the unique challenges of openhole operations, formation technical difficulties, high-stakes economics, and untapped high potential from intermittent reservoirs. This paper presents post-job results obtained from stimulating multiple zones along the lateral and describes the lessons learned in implementing this methodology, which can now be considered best practice for applications with similar challenges in other fields.
