Embedment of High Strength Proppant into Low-Permeability Reservoir Rock
SPE/DOE Low Permeability Gas Reservoirs Symposium, 1981ABSTRACT Embedment of sintered bauxite into Berea, sandstone core, and shale core at closure pressures up to 10,000 psi (69 MPa) is reported. Several variables influencing fracture closure are examined: closure pressure, proppant size and size distribution, proppant concentration (up to a monolayer), formation hardness and surface ...

Indentaion Hardness for Improved Proppant Embedment Prediction in Shale Formations
SPE European Formation Damage Conference and Exhibition, 2015Abstract The aim of hydraulic fracturing is the generation and maintenance of highly permeable pathways. To achieve this, a high hydraulic pressure is applied to overcome the breakdown pressure in developed formations. To avoid the closure of the generated fractures due to the acting in-situ stress in the subsurface, proppantsareused ...

Impact of Remedial Acid Practices on Proppant Embedment and Fracture Face Permeability
SPE Annual Technical Conference and Exhibition, 2020Abstract Acid stimulation is a common remedial practice for formations that produce below the target production rates. Acid stimulation can be performed during the early-life of a well, soon after the well is put on production, or more typically, following a production period once production rates have started to decline.

Modeling Fracture Closure with Proppant Settling and Embedment during Shut-In and Production
SPE Drilling & Completion, 2020Summary Fracture closure and proppant settling are two fully coupled processes during both shut-in and production. Proppant distribution greatly affects the residual fracture width and conductivity evolution, whereas fracture closure might limit proppant settling and force the proppant to crush or embed into the rock.

Mathematical Modeling of Proppant Embedment and Its Effect on Conductivity of Hydraulic Fracture
SPE Russian Petroleum Technology Conference, 2017Abstract The proppant embedment into rock during the operation of the hydraulically fractured well is one of the reasons for the production rate decrease. Most researchers analyze this problem on the basis of laboratory experiments and do not take into account the well production data.

The Effects of Fracturing Fluids on Shale Rock Mechanical Properties and Proppant Embedment
SPE Annual Technical Conference and Exhibition, 2011Abstract The development of shale reservoirs has grown significantly in the past few decades, spurred by evolving technologies in horizontal drilling and hydraulic fracturing. The productivity of shale reservoirs is highly dependent on the design of the hydraulic fracturing treatment. In order to successfully design the treatment, a good

Effects of placement pattern on the elastoplastic embedment behavior of multi-sized proppants
The efficient development of coalbed methane (CBM) resources is of great significance for advancing the energy transition. However, the embedment behavior and quantitative characterization of multi-sized proppants remain key challenges in CBM fracturing design.Xuanshi Zhu +6 more
