Effect of wettability of ceramic proppant surface in guar gum solution on the oil flow efficiency in fractures

Petroleum, 2019
Guar gum and its derivatives have been the most commonly used polymers to increase the viscosity of fracture fluids. Ceramic proppants are vital products for enhancing oil and gas well productivity in low-permeability reservoirs.

Feasibility of Proppant Flowback Control by Use of Resin-coated Proppant

Journal of Basic & Applied Sciences
Proppant flowback is a problem in Xinjiang oilfield. It decreases production rate of a fractured oil well, corrodes surface and downhole facilities and increases production costs. Curable resin-coated sand is a common technique to control proppant flowback.

The influence of fracturing fluid temperature and viscosity on the migration and distribution of proppants within a fracture

Journal of Petroleum Exploration and Production Technology
This work presents a numerical study incorporating the impact of temperature variations along the fracture on the viscosity of fracturing fluids and consequently on proppant distribution in hydraulic fracturing. Traditional models have not considered non-

Efficient placement technology of proppants based on structural stabilizers

Petroleum Exploration and Development
Fiber is highly escapable in conventional slickwater, making it difficult to form fiber-proppant agglomerate with proppant and exhibit limited effectiveness. To solve these problems, a novel structure stabilizer (SS) is developed.

Simulation and solution of a proppant migration and sedimentation model for hydraulically fractured inhomogeneously wide fractures

Energy Exploration & Exploitation
The distribution of proppant during hydraulic fracturing may directly contribute to the flow conductivity of the proppant fracture, so research on the migration and sedimentation of proppant in the fracture and the final distribution pattern is of great ...

The Calculation of Coal Rock Fracture Conductivity with Different Arrangements of Proppants

Geofluids, 2018
An accurate evaluation of coal rock fracture conductivity is an important prerequisite for predicting the productivity of CBM wells. Coal rock is soft and fragile, with low elastic modulus and high Poisson ratio.

Permeability of large‐scale fractures with ununiform proppant distributions in coalbed methane development

Energy Science & Engineering
The coalbed methane (CBM) productivity is directly determined by the fracture permeability during hydraulic fracturing, which is regulated by the distribution of proppants.
