New Methods Analyze Asphaltene Deposition and Fouling in Reservoirs
Asphaltene precipitation and deposition in production tubing and surface facilities are well-documented issues, and different methods are available to manage them.
Formation Damage: A Novel Approach in Evaluating Zonal-Productivity Loss
The paper describes a novel methodology to construct distributed formation damage across openhole wells in carbonate reservoirs and to evaluate the effects of damage on zonal productivity.
One of the challenges for those involved with understanding an unexpected decline in well performance is identifying the exact causes for the reduced productivity. Consideration of all data available can eventually point toward one factor that could explain productivity decline.
Removing Fines-Migration Formation Damage in the Putumayo Basin in Colombia
This paper summarizes a wide variety of sandstone-acid-stimulation case histories, highlighting aspects such as mechanical conditions and operational practices.
Integrated Approach To Managing Formation Damage in Waterflooding
Understanding of formation damage is a key theme in a waterflood project. An integrated multidisciplinary approach is required to determine an optimal design and strategy.
Method for Monitoring Mud Contamination in Wireline-Formation-Tester Sampling
The wireline formation tester (WFT) is a well-developed technology used to collect representative downhole fluid samples. The authors introduce a simple but effective method for monitoring WFT sampling when targeting the low levels of contamination needed for asphaltene-onset-pressure analysis.
Does formation-damage coreflooding give a good representation of damage that occurs downhole? For those of us who are actively involved in coreflooding, this is a common question to be asked.
Formation-Damage Diagnosis Facilitates Successful Remediation in Sandstone
Well-control fluids were used during a routine overbalanced workover operation in an offshore well completed in high-permeability sandstone.
Filtrate and Mudcake Characterization: Implications for Formation-Damage Control
This paper focuses on experimental methods quantifying water-based muds and investigating effects on particle bridging, filtrate invasion, and permeability.
Controlling Losses When Recompleting Low-Pressure Reservoirs
A challenge in many permeable, water-sensitive, subhydrostatic reservoirs is avoiding the loss of completion fluid when completing or working over wells.
