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.

Impact of Damage Mechanics on Sand Production and Reservoir Formation Damage

International Geomechanics Symposium, 2022
Abstract Changes in the magnitude of the effective stresses due to hydrocarbon production will lead to formation failure in the reservoir rock and around the wellbore. The failure around a wellbore and within the reservoir formation assumes that rock can fail due to mechanical damage within the formation.

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.

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.

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

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

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.

Formation damage and remedial stimulation

Clay Minerals, 1986
AbstractIt is argued that a wide range of engineering data and geological data is required to make confident prognoses or diagnoses of formation damage. Potential sources of data are reviewed, with comments on their limitations. It is proposed that microscopic failure can cause formation damage in macroscopically intact rock at stress concentrations ...

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).
