The staged and layered fracturing technology plays an important role in unconventional tight reservoirs. And the gas well fracturing and completion integration is the core component to realize the fracturing and completion integration process, which can realize the integration of acid fracturing and later drainage production so as to reduce the secondary pollution to the reservoir. The packer rubber barrel’s performance directly affects the long-term effective sealing reliability itself in high temperature and high pressure environment. In this paper, the constitutive model of rubber tested from high temperature and high pressure curing kettle to simulate the high-temperature and highly corrosive environment of the formation. On this basis, the structure of the packer’s shoulder and the protective ring of the rubber barrels are optimized through Abaqus to reduce its stress failure under high pressure, and its corrosion resistance is improved by improving the rubber material. The sealing performance of the packer rubber cylinder under the field underground requirements is tested through laboratory evaluation test and field test. The results show that the protective ring and rubber tube shoulder at 30° angle are a reasonable result of optimization, and the optimized packer can meet the requirements of 154 °C temperature resistance, 79 MPa pressure bearing and long-term effective sealing. The successful development of packer rubber and the integrated analysis process can lay a solid foundation for the realization of integrated fracturing and completion process for exploration and development of deep volcanic or carbonate reservoirs.

Summary The loss of well integrity in oil and gas and CO2 injection wells provokes leaks that potentially pollute underground water reservoirs and the surrounding environment. The present publication reviews the existing literature investigating the loss of well integrity due to damage development in the cement sheath, focusing on qualitative and mainly quantitative information regarding cracks, effective permeability, and leak flows. Methods applied for leak detection on-site are reviewed, and the difficulties of these methods in providing quantitative results are highlighted. The outputs of laboratory experiments and computer simulations, considered essential to complement on-site measurements, are also reported. The review of the existing literature shows that for most of the damaged cement sheaths the observed crack widths range between 1 and 500 µm, the permeability ranges from 10−17 to 10−12 m2, and the leak rates range between 10 and 10 000 mL/min for gas leaks and between 1 and 1000 mL/min for oil leaks.

Objectives/Scope The Horizontal wells enhance reservoir performance by placing a long wellbore section within the reservoir. As they help in reducing water and/or gas production, increasing oil rates, reducing sand production and finally in achieving efficient drainage of the reservoir. The inflow control devices (ICDs) are used to address the issues of premature water and/or gas breakthrough, uniform flow distribution and reservoir depletion in the oilfield. They reduce the flow of unwanted fluids and balance the production distribution across the entire lateral section. The production contribution across the ICDs monitoring to take necessary remedial action is one of the challenges in this type of completion. In this case study, the main objective was to determine the contribution profile and source of water in horizontal well with passive ICD completion installed back in 2011. The various challenges were the low production rate, heavy oil with water, erratic and inconsistent nature of the well flow, ESP design test with lack of recent flow results, and lack of some data about the ICDs. In addition, unlike most of the cases where the ICDs are installed in open hole, this case the ICDs are installed in 7in liner with nine perforation intervals. Methods, Procedures, Process This paper presents the use of multi arrays production logging combined with spectral noise and high precise temperature tools, to determine the contribution profile and source of water in this challenging ICD completion. Results, Observations, Conclusions The contribution profile across the ICDs was determined using the multi arrays production logging data and temperature simulation models assisted by noise data. The results were in contrary to the previous production logging results and helped significantly in the design of proper ICD cleaning operations. The work-over resulted in successfully restoring and attaining high oil gain. Novel/Additive Information The innovative combination of multi arrays production logging combined with spectral noise and high precise temperature tools to determine the contribution profile and source of water in horizontal well with ICD completion.
