Abstract:

Tight oil can be commercially recovered by horizontal well multistage fracturing. With the development of multistage fracturing tools, extended reach horizontal well could be a way to enhance unconventional tight oil economical efficiency. On the base of the study on Cardium formation, fracturing fluids were analyzed and slick water fracturing fluid was optimized. Frac port multistage fracturing string was studied and applied in pilot tests. Three extended reach horizontal wells with average 40 stages and 2954m horizontal length pilot tests were applied and studied. Comparison of well costs an

Abstract:

Summary This paper presents a discussion of the pressure-transient responses of horizontal wells in anticlinal structures and curved and undulating wells in slab reservoirs. It confirms that, in the absence of a gas cap, conventional horizontal-well models may be used to approximate the flow characteristics of the systems in which the trajectory of the well does not conform to the curvature of the producing structure. If a gas cap is present, however, the unconformity of the well trajectory and producing layer manifests itself, especially on derivative characteristics when the gas saturation i

Abstract:

Water breakthrough and the flow of water towards the perforations of a producing well increase production operation costs and influence overall recovery efficiency. To control water production, a downhole water sink can be used in which a well is completed in both oil and water zones. Water is produced from an interval in water zone, which can result in the same pressure drop below water oil contact (WOC) as the pressure drop created by oil or gas production. This system can reduce water production through oil zone perforations. Water produced from water zone perforations can then be injected

Sanding risk assessments were conducted at different stages of development of Geographe field in the Otway Basin, Australia. The initial sanding analysis was conducted using the exploration and appraisal wells data in 2010. This analysis showed low sanding risk for the planned wells with the expected production plan. The sanding model was then updated in 2014. Logs, core tests and sand-free production data from the early production wells were used to improve the initial sanding model. The updated model reconfirmed the low sanding risk for planned horizontal wells and suggested no sand control

Of the three chemicals tested, a monomer, a polyacrylamide, and a plastic, only the plastic plug had a sufficiently high holding pressure.

Water coning is described as an upward movement of water into the perforation in oil-producing wells which lead to water production along with the crude oil.

Abstract:

Summary The cold-production-recovery process, also known as cold heavy-oil production with sand (CHOPS), is a method for enhancing primary heavy-oil production by aggressively producing sand. It is successful in vertical (or slanted or deviated) wells in western Canada. In this process, large amounts of sand are produced on a continuing basis along with heavy oil. Attempts at cold production in horizontal wells have not been particularly successful. When sand production has been generated in horizontal wells, these wells have tended to become plugged with sand. This paper presents the results

Summary Implementing water injection during the early stage of a new reservoir's development is a process that is gaining popularity around the world. This is especially true in Saudi Arabia, where water injection is used both to improve oil recovery and to maintain pressure by placing short or long horizontal water-injection wells around the reservoir flanks. For cases where water-injection wells are placed in reservoir flanks, some of the producing wells are perforated transverse to the water-injection wells to improve the oil recovery around the involved areas.

The article explores the reasons causing gas breakthrough from the gas cap into the producing wells and oil penetration into the gas–saturated part of the formation at the Fedorovskoe Field. It appears that gas breakthrough to the perforated intervals of producing wells are mainly caused by the geological structure of AS4-8 formations (absence of robust shale break/screen) and relatively small distances from the upper filter holes to the gas– and gas-and-oil–saturated portion of the formation. Two operation modes applicable for this field are described: for the well

Abstract:

Historically, horizontal wells in coal seam gas (CSG) producing areas of Australia have been limited in their ability to stimulate horizontal wellbores with hydraulic fractures, despite most basins being in favourable stress states capable of generating multiple transverse hydraulic fractures. In some cases, overlapping mining tenements limit the ability to effectively deploy steel casing completions to effectively manage multi-stage fracture stimulations along the lateral. In other cases, potential wellbore instabilities preclude the placement of laterals with adequate length to stage numerou

Abstract:

Summary Cotton Valley tight gas sands in the East Texas basin of North America consist of very-fine-grained, well-sorted quartz arenites and subarkoses that are overprinted by significant diagenetic processes. Stratigraphic variations in rock type control gas production. Hydraulic fracturing delivers economic gas production. We drilled horizontal wells more than 4,000 ft long consisting of more than 12 hydraulic-fracturing stages. The good gas-producing rock-type reservoirs are usually less than 14-ft thick and exhibit strong diagenetic overprint. Low gas prices challenge the use of sophistica

Abstract:

Water inflow to petroleum wells hampers production of oil or gas leading to early shut downs of the wells without sufficient recovery of hydrocarbons in place. Downhole water sink (DWS) is a completion/production technique for producing water-free hydrocarbons with minimum amount of water from reservoirs with bottom water drive and strong tendency to water coning. DWS eliminates water invasion to hydrocarbon production by employing hydrodynamic mechanism of coning control in situ at the oil-water or gas-water contact. The mechanism is based upon a localized water drainage generated by another

Abstract:

Summary Long (horizontal) completion intervals typically show a wide variation in the inflow distribution along their length because of either formation heterogeneity or (frictional) flow pressure losses. Monitoring of the inflow profiles in such wells is an important step in efficient reservoir management. Accurate temperature measurements [using distributed temperature sensors (DTSs), permanent downhole gauges (PDGs), or other forms of production logging] have become more widely available in recent years. Many published papers describe temperature sensing and its phenomenological interpretat

The majority of reserves of small oil companies of the Republic of Tatarstan are represented by carbonate reservoirs with low filtration and capacitance properties, low reservoir pressures and high oil viscosity.

Thermal methods are considered as the most effective technologies for deposits with high-viscosity oil.

Abstract:

Shale gas extraction is hindered by the complex geological conditions of shale reservoirs, such as deep burial, low permeability, and multi-zone characteristics. Therefore, horizontal well hydraulic fracturing is essential for improving reservoir permeability. However, fracture interference and fracturing fluid retention can lead to gas–water co-production. Existing models for predicting the productivity of fractured horizontal wells typically focus on single-phase flow or do not fully account for fracture interactions and dynamic water saturation changes. In contrast, this study introduces a

Limited horizontal drilling has occurred within the Niobrara-equivalent section of the Mancos Shale in the Piceance Basin, and the results from individual wells are highly variable.

However, when making use of the traditional SAGD technique (the production and injection well are located on the same axis with the horizontal well spacing of 0 m), the steam chamber development is usually insufficient because of the high longitudinal sweep rate of steam, which seriously influences the SAGD performance for developing thin layer oil sand reservoirs especially.
