Field-proven chemistry for better oilfield performance.
PECOME develops specialty chemical products and integrated fluid systems for drilling, completion, fracturing, workover, and production operations.
About PECOME
Laboratory insight. Field-ready execution.
Founded in 1998 and headquartered in Beijing, PECOME brings together R&D, manufacturing, technical service, and field application experience. Our work focuses on practical oilfield problems while advancing lower-sulfonated, lower-black-asphalt, environmentally oriented water-based fluid systems for wellbore stability, reservoir protection, filtration control, lubrication, plugging, and production enhancement.
Why PECOME
Chemistry built around field engineering problems
Sealing, environmental performance, and reservoir protection
NFA-25, NAX50, Redu products, and NATU natural-polymer technologies support microfracture sealing, filter-cake quality, sulfonated-material reduction, and reservoir protection.
Stimulation and proppant transport
FloatX gas-suspended proppant technology and weighted organic-salt stimulation fluids support proppant transport, pressure control, and production enhancement.
Founded in 1998
Started from a hard problem in the Southern Junggar Margin
For many years, the Southern Junggar Margin was viewed as a highly prospective exploration area, yet complex formations, wellbore instability, and drilling incidents prevented multiple wells from reaching their targets. In 1997, Xinjiang Petroleum Administration launched a renewed technical campaign and sought collaborative research support across drilling engineering, mud systems, cementing, and related disciplines.
PECOME was founded in March 1998 in response to that field challenge. The company proposed the Weigh organic-salt technology route around two practical principles: stronger inhibition and lower solids content. After research programs and field trials, the technology helped complete the first accident-free well in 20 years on the Southern Junggar Margin to reach its target interval in 2001. That beginning shaped PECOME’s long-standing way of working: close to the customer, jointly solving technical problems, and delivering field-proven solutions.
Alternative to Sulfonated Asphalt
NFA-25®
A nonfluorescent, non-asphaltic alternative to sulfonated asphalt that improves filter-cake quality, seals microfractures, and reduces reliance on conventional black asphalt additives.
Solid Polyglycol
PGCS-1® Solid Polyglycol
A solid polyglycol additive for water-based drilling fluids, supporting lubricity, active-shale inhibition, fluid-loss control, and easier field handling.
Nano Sealing
NAX50 Nano Sealing Additive
A nano-scale sealing material for microfractures, nanopores, coal, and shale formations, helping improve wellbore stability and reduce fluid loss.
Organic Salts
Weigh® Organic-Salt Series
Organic-salt products for solids-free and low-solids drilling, drill-in, completion, and weighted stimulation fluids where density control and inhibition matter.
Natural Polymers
NATU® Natural-Polymer Series
Natural-polymer and encapsulation technologies developed for environmentally sensitive operations, reservoir protection, cuttings encapsulation, rheology control, and filtration control.
Fluid Systems
Integrated fluid systems
Drilling FluidsWellbore stability, inhibition, lubrication, and fluid-loss control.
Drill-in FluidsSolids-free or low-solids systems, compatibility, and reservoir protection.
Completion FluidsPerforating, kill, workover, and annulus-protection fluids.
Fracturing FluidsAero-suspended proppant transport, weighted stimulation, and production support.
Workover & Production AdditivesTroubleshooting, formulation adjustment, and field support.
