“…This process can significantly improve well productivity in low permeability reservoirs. A single well can be frequently produced from many zones due to economic considerations which makes it difficult to fracture them all at once since one zone must be separated while the other is being treated [26,27]. These costs comprises of completion costs, fluid and proppants costs, and pumping charges [28].…”

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 Antelope Shale reservoir, a member of the Monterey Formation in the San Joaquin Valley, offers unique opportunities and challenges. The reservoir comprises three silica phases: Opal A (Diatomite), Opal CT, and Quartz. While the industry has been successful in producing from Opal A (Diatomite) via cyclic steam operations, the resources in the Opal CT and Quartz phases are yet to be commercially established. The recoverable oil estimate from the Monterey was downgraded by the Energy Information Administration (EIA) by 96% from approximately 15 billion barrels to 600 million barrels. Elk Hills and North Shafter have been successfully producing from the Antelope Shale reservoir. However, the reservoir rock and fluid properties are varied such that extrapolation from one field to the other is difficult. The Opal CT and Quartz commingled completion and stimulation in the McKittrick field showed encouraging initial production response followed by steep decline and operational challenges. In general, deep drilling and stimulation is expensive in San Joaquin Valley. Industry learning has been slow, less data is available for quality data analytics, which in turn impacts the learning process. In a brown field dominated heavily by thermal recovery processes, unconventional development gets challenged due to higher cost, longer lead times, and relatively poor economics. A typical unconventional resource field takes 4-5 years for achieving optimal development strategy. In a $50 oil price business environment, incremental progress in not enough. We need breakthroughs. It is imperative to optimize the pilot phase and early economic learning for sustainability of the project In this paper, we discuss the case study of a pilot project wherein four vertical wells were drilled in the McKittrick field. The results showed opportunities for a bigger development plan but were challenged by operational issues, limited analog data set, higher cost, poor economics, and comparison with traditional heavy oil projects. We will also discuss some additional improvement opportunities including imbibition, and drawdown management that have been theoretically established elsewhere and, if applied, could add value to improve the project economics.
