Water Conformance Control
Achieve a Longer Productive Well Life
Management of unproductive water has been a major challenge facing the hydrocarbon industry. Our Company has developed a number of chemical technologies to help reduce unwanted water production, enhance recovery efficiency, and satisfy a broad range of reservoir management and environmental objectives. DOSAS presents an engineered approach to the water shut off, to examine the severity of the water production problem, and to understand the best solutions available to address these excess water issues, for the highest chance of chemical treatment success.
Our Engineering Support Team is committed to matching conformance problems to conformance-improving technologies that help you with better sweep efficiency during oil-recovery flooding operations, increased and incremental oil recovery, IOR, accelerated oil-recovery rates and improved business profitability, reduced oil-production expenses (OPEX) through the reduction of unnecessary recycling of driving fluids (e.g., water and/or polymer solution) and the associated lifting, handling, treatment, environmental-related, and disposal costs extended economic lives of certain oil reservoirs that are approaching their economic limit and reduced environmental liabilities and increased environmental benefits (e.g., produce less saline, heavy-metal-containing, and/or H2S-containing produced water).
DOSAS offers specific chemicals to deal with the numerous challenges faced in dealing with excess water, in order to guarantee the most cost-effective solutions, while paying close attention to reducing environmental impact.
This a new technology and innovative technique during matrix stimulation which uses a novel diverting agent to isolate or temporarily block high permeability and/or potentially water bearing zones, diverting matrix stimulation treatments to lower permeability zones, to access untouched reserves.
Our innovative Technology is a strategically designed, low risk, production optimization technique used for simultaneously stimulating untouched reserves, while isolating water zones....
Polymer gels, due to their versatile nature, are deemed suitable for reducing water production from oil and gas fields. Treatments utilizing these materials are designed with the specific objective to improve reservoir conformance.
WaterCurb™ LMW-5 is a water shut off additive to form a strong rigid gel. The product is crosslinkable copolymer based on low molecular weight polymer and rate of gelation is controllable through crosslinker concentration......
WaterCurb™ HMW-1 is a water shut off additive and crosslinkable copolymer based on high molecular weight polymer. It is a flowing gel for in-depth blocking of high permeability zones to seal fractures, fissures, and......
Relative Permeability Modifier
RPM’s are used for excess water shutoff and sand control in offshore and onshore oil and gas fields. These microgels, once placed in the formation, adsorb onto the rock surface, collapse under capillary pressure, and reduce the relative permeability of water.
Relative Polymer Modifiers are polymers or weak polymers gel that adsorbs onto the surface of pore spaces and/or rents in pore throats....
There is a specific set of criteria for the well to meet in terms of completion and production, in order to be considered a suitable candidate for WaterCurb™ RPM, and for a treatment to......
