An Experimental Study for Mechanical Formation Damage

International Symposium and Exhibition on Formation Damage Control, 2002
Abstract This paper presents a new methodology to evaluate mechanical formation damage due to drilling and oil production. The methodology covers a wider range of stress path adding new insight to fluid flow analysis in porous media. In some reservoirs occur large deformations during oil production due to the increasing of effective ...

Biological Control of Formation Damage

International Symposium and Exhibition on Formation Damage Control, 2002
Abstract Conventional drilling fluids usually contain various polymers, which are the main cause of formation damage. A biological method, which could efficiently reduce this type of damage, was developed. Several halotolerant and thermotolerant microorganisms were isolated and their ability to degrade polymers was tested.

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.

Formation Damage Challenges in Geothermal Reservoirs

2018
Decline of well productivity due to migration of fine particles is a well-known phenomenon occurring during exploitation of geothermal reservoirs. We performed several laboratory fines migration tests using natural reservoir cores, taken from geothermal fields.

Damage formation in polymers

International Journal of Engineering Science, 1984
Abstract This paper describes the application of a NAG (Nucleation And Growth) computational model to void accumulation during quasistatic tests of polymers and discusses some experimental techniques used to detect and quantify damage (i.e., void or microcrack accumulation) in these materials. The experimental techniques described here are ultrasonic

Detection Of Deep Formation "Damage"

Annual Technical Meeting, 1968
Abstract The characteristics of deep formation "damage" and low permeability appear quite similar on a formation test conducted in a normal manner. As a result, with such tests, a good reservoir with deepdamage appears quite similar to a poor reservoir with low permeability.

Storage Formation Damage Mechanisms

Proceedings of SPE Eastern Regional Meeting, 1997
Abstract Utilized for natural gas storage since 1953, the Six Lakes Field has experienced an annual deliverability decline of 5.6%. Peak days in February have decreased from a high of 568 MMcf/d in 1968 to a low of 182 MMcf/d in 1992.

Role of Polymers on Formation Damage

SPE European Formation Damage Conference, 1999
Abstract The filter cake is critical in preventing reservoir invasion by mud filtrate. This is of particular importance in open hole completions where damage cannot easily be bypassed. However little is known about the selectivity of the filtercake in controlling which components will invade the reservoir. An EC funded consortium between

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 Damage by Fines Migration

2018
One of the widely spread causes of reservoir formation damage is fines migration. Migration of natural reservoir fines occurs during commingled production of oil or gas with low-salinity water, during high-rate production or injection, with low-salinity waterflooding and its combinations with enhancd oil recovery (EOR).
