Formation Damage Associated With Mineral Alteration and Formation of Swelling Clays Caused by Steam Injection in Sandpacks

SPE Reservoir Evaluation and Engineering, 2020
Thermal-recovery methods are commonly used for production of viscous crude oil. Injected hot fluids react with reservoir rock, and some of these reactions might result in a change to the reservoir mineralogy. Depending on the physicochemical conditions

A transient two-phase flow model for production prediction of tight gas wells with fracturing fluid-induced formation damage

Journal of Petroleum Science and Engineering, 2019
A major concern with hydraulic fracturing in tight formation is the fracturing fluid-induced formation damage (FFIFD) for the high capillary pressure and the presence of water-sensitive clays.

Formation Damage and Well Productivity Simulation

8th European Formation Damage Conference, 2009
Abstract In this paper we describe a simulation model for computing the formation damage imposed on the formation during overbalanced drilling. The main parts modelled are filter cake build-up under both static and dynamic conditions, fluid loss to the formation, transport of solids and polymers inside the formation including effects of ...

Formation-Damage Assessment and Filter-Cake Characterization of Ca-Bentonite Fluids Enhanced with Nanoparticles

, 2020
Invasion of mud filtrate while drilling is considered one of the most common sources of formation damage. Minimizing formation damage, using appropriate drilling-fluid additives that can generate good-quality filter cake, provides one of the key ...

An Engineered Formation-Damage-Control Drill-In Fluid Technology for Deep-Fractured Tight-Sandstone Oil Reservoir in Northern Tarim Basin

SPE Drilling & Completion, 2020
Conventional drill-in fluid commonly induces formation damage during the drill-in process in deep-fractured tight reservoirs, which results in severe well-production decline.

Technology Focus: Formation Damage

Journal of Petroleum Technology, 2018
Technology Focus Coreflooding is one of the principal tools through which we qualify drilling and completion fluids and assess the potential for formation damage, but is it relevant? By “relevant,” I mean does it give an accurate portrayal of the likely performance of the selected fluids in terms of potential damage and how effectively a

Formation of ion damage tracks

Physics Letters A, 1984
The formation of damage tracks in insulators from the passage of energetic (MeV/amu) ions indicates that the energy lost by an ion to electronic excitation is partially transferred to atomic motion. It is known that a track consists of localized regions of extended defects that are separated by lengths that exhibit only point defects.

Experimental Study and Pore Network Modeling of Formation Damage Induced by Fines Migration in Unconsolidated Sandstone Reservoirs

, 2020
Fine migration is always considered as one of the major mechanisms that are responsible for formation damage. The unwanted reduction of reservoir permeability would result in the decline of water injection and consequent oil production, especially for ...

Effects of Kaolinite on Fines Migration and Formation Damage

, 2020
The presence of residual oil or gas during fines migration in porous media greatly affects particle mobilization and capture. This paper investigates the effects of kaolinite content on fines migration and formation damage in the presence of oil ...
