Formation damage refers to a reduction in reservoir permeability near the wellbore caused by drilling and completion fluids. The presentation discusses formation damage causes such as swelling clays, fines migration, and wettability changes. Formation damage indicators include permeability impairment and reduced well performance. Common cleaning methods involve simple cleanup flows, though the timing of damage removal is not fully understood. Prevention focuses on controlling operations that can lead to damage like drilling, cementing, and perforating.
Skin factor is a dimensionless parameter that quantifies the formation damage around the wellbore. it also can be negative (which indicates improvement in flow) OR positive (which means formation damage exists). Positive skin can lead to severe well production issues and thus reducing the well revenue

There are three primary techniques of EOR: gas injection, thermal injection, and chemical injection. Gas injection, which uses gases such as natural gas, nitrogen, or carbon dioxide (CO2), accounts for nearly 60 percent of EOR production in the United States. Thermal injection, which involves the introduction of heat, accounts for 40 percent of EOR production in the United States, with most of it occurring in California. Chemical injection, which can involve the use of long-chained molecules called polymers to increase the effectiveness of waterfloods, accounts for about one percent of EOR production in the United States. In 2013, a technique called Plasma-Pulse technology was introduced into the United States from Russia. This technique can result in another 50 percent of improvement in existing well production.
Reservoir engineers cannot capture full value from waterflood projects on their own. Cross-functional participation from earth sciences, production, drilling, completions, and facility engineering, and operational groups is required to get full value from waterfloods. Waterflood design and operational case histories of cross-functional collaboration are provided that have improved life cycle costs and increased recovery for onshore and offshore waterfloods. The role that water quality, surveillance, reservoir processing rates, and layered reservoir management has on waterflood oil recovery and life cycle costs will be clarified. Techniques to get better performance out of your waterflood will be shared.
The presentation highlights the root causes of major drilling issues such as formation pressure uncertainty, subsurface feature like mud volcanoes, major fault, poor well planning & etc. Then it elaborates on consequences of all above on examples of wellbore instability, sticking, gumbo & so on.

Well test analysis in horizontal wells is applied to find the reservoir parameters like permeability and skin factor and the result from the chosen methods will be compared to the result of some famous software like Kappa Saphir, PanSystem, etc which are used in oil and gas industries.
Formation Damage Identification and Prevention, Mohammed Khalid AbdullahMohammed Khalid Abdullah
During drilling operations, the formation will be damaged. This damage might be caused by invasion of the mud filtrate and solid particles in the mud used for weighting the drilling fluid ,or fluid loss control materials and other additives as well as drill solids. Or during cementing operations, the main formation damage problem during the cementing operations of the casing is the cement and spacer filtrate into the sensitive formations. The spacer is a fluid used to separate the drilling fluid and the cement slurry from each other. These fluids are mostly high fluid loss and abrasive fluids. This high fluid loss property causes the fluid to filtrate into the formation and cause damage.
Abstract This case study examines the formation damage that occurred i.pdfatozbazar
Abstract This case study examines the formation damage that occurred in an oil field located in
the Casanare region of Colombia. The oil field had been producing oil for several years, but the
operators noticed a significant decline in production rates. The investigation revealed that the
well was suffering from severe formation damage, which was caused by the accumulation of
drilling fluids and other contaminants in the reservoir. To address the formation damage, the
operators implemented a variety of remediation techniques, including acid stimulation, matrix
acidizing, and hydraulic fracturing. These techniques were designed to dissolve the contaminants
in the reservoir and increase the permeability of the formation, allowing oil to flow more easily
to the wellbore and to the understanding of formation damage mechanisms. The Ruba field is
one of the largest oil fields in Colombia and has been in production since the 1980 s. The oil
extracted from the Ruba field is a heavy crude oil, which requires more advanced refining
techniques to produce high-quality fuels. The Ruba field is operated by several major oil
companies, including Ecopetrol, the national oil company of Colombia. The concept of skin and
formation damage play a vital role in productivity of an oil well. The effect of formation damage
zone on the well flowing pressure was introduced to the original solution of diffusivity equation.
Formation damage reduces the well production. Skin defines as the area of reduced permeability
near the wellbore due to the invasion of drilling fluid into the reservoir rock. Classifying damage
requires a lot of work to determine correctly the main reason of it. In general, fluids can interact
with reservoir rock and cause formation damage that impedes hydrocarbon production. Tight
sandstone reservoir with well-developed natural fractures has a complex pore structure where
pores and pore throats have a wide range of diameters; formation damage in such type of
reservoir can be complicated and severe. Reservoir rock samples with a wide range of fracture
widths are tested through a several step core flood platform, where formation damage caused by
the drilling or fracturing fluid, where any unintentional fluid impedance in or out of a wellbore is
referred to as damage to formation. This general definition includes the flow restriction caused
by reduced permeability in the near wellbore region. Formation damage Description and
classification: The history of damage removal is a process that begins with the identification of
the issue. This usually involves looking through the various sources of information related to the
well, such as drilling records, completion designs, and operator experiments. The desired
purpose is to identify the causes of the formation damage and how it could be fixed. Where the
types of formation damage location of damage extent and screening of damage, and effect of
damage on well production or injection. Well development and res.
This course is intended for industry professionals who wish to develop or expand their knowledge of formation damage and how optimum productivity and injectivity can be assured.
The Challenges of Wastewater Structural Degradation and Mitigation Strategies A.W.Chesterton
A recent NACE sponsored report pegged the annual cost of corrosion in the water and wastewater sector in the USA as exceeding 36 billion dollars/year. Much of this has to do with the age of the infrastructure and the operating conditions it is exposed to, which have become significantly more aggressive than what the original design construction methods and materials are capable of handling. A specific area of focus will be on protective coating technologies, differentiating between the primary systems in use, and how to implement a protective coatings solutions-based approach to slowing or halting attack
Thermal pollution, sometimes called "thermal enrichment," is the degradation of water quality by any process that changes ambient water temperature. A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. Other causes of thermal pollution include soil erosion.[citation needed] This will elevate water and expose it to sunlight. When water used as a coolant is returned to the natural environment at a higher temperature, the sudden change in temperature decreases oxygen supply and affects ecosystem composition. Fish and other organisms adapted to particular temperature range can be killed by an abrupt change in water temperature (either a rapid increase or decrease) known as "thermal shock."
Urban runoff—stormwater discharged to surface waters from roads and parking lots—can also be a source of elevated water temperatures.
Evaluation of a systematic approach to matrix acidizing on an oil producing welleSAT Journals
Abstract All wells are susceptible to formation damage to some degree, ranging from relatively minor loss of productivity to plugging of specific zones. Formation damage could simply be referred to as a term used to emphasize reduced current production. Acidizing is a well stimulate technique where acids are primarily used to remove or cure damage around wellbore caused by drilling, completion, production and work over operations in order to improve production. In matrix acidizing, acid is used to remove the damage near the wellbore. This removal of severe plugging in sandstone, limestone or dolomite by matrix acidizing process can lead to large increase in well productivity. It is expected that matrix acid treatment should remove flow restrictions near the wellbore and allow the well to produce at an undamaged rate. However, the production rate after treatment is sometimes lower than predicted or in extreme cases without any improvement at all. This study evaluates matrix acidizing operations in oil producing wells with a view to identifying causes of acidizing failures and developed a systematic approach to matrix acidizing that will eliminate failures and greatly enhance the performance of acidized oil wells. Discussions have been centered on the fundamentals of formation damage and acidizing, review of existing literature on the subject and matrix models. In treated wells studied, stimulation ratios from productivity indices were almost equal to or greater than 2 (≥ 2) and always greater than stimulations ratios from production rates, showing that the treatments were positive in reducing or curing damage around the wellbore but the stimulation ratios from the two parameters (productivity index and production rate) were not the same as a result of flow restrictions. Since all treated intervals in the different wells studied showed positive response to damage reduction, it could be concluded that acidizing if properly executed will reduce or cure damage around the wellbore and improve productivity. Key Words: formation damage, matrix acidizing, stimulation, and productivity, stimulation ratio, etc…

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

What Does Formation Damage Do?
Formation Damage Causes, Prevention, and Remediation
Reduction of reservoir productivity
Non-economic operations
Although we do not have the ability to control
reservoir rock properties and fluid properties,
we have some degree of control over drilling,
completion, and production operations.

Observations on Damage
Formation Damage Causes, Prevention, and Remediation
o Shallow damage is the most common and makes the biggest
impact on production.
o It may take significant damage to create large drops in
production
o The problem, however, is that the highest permeability zones
are the easiest to damage, and that can have a major impact
on productivity.

o Formation damage mechanisms vary depending on the well
operation types and reservoir and fluid conditions.
o Oil and gas recovery can be enhanced by minimizing and
controlling of formation damage.
o Formation Damage can cause significant decreases in well
productivity and worldwide yearly lost production due to
Formation Damage is equivalent to billions of dollars in lost
revenue. Identification and reduction of Formation Damage
problems can lead to immediate returns in the form of increased
production rates and extension of the life of any field.
