About PECOME
From laboratory formulation to oilfield application
Beijing PECOME Technology Development Co., Ltd. integrates technical research, industrial manufacturing, product supply, and technical service for major oilfields in China and selected overseas projects. Its technology portfolio includes Weigh2®, Weigh3®, Weigh4®, IND30®, NAT20®, Redu1®, NFA-25®, NAX50TM, and PGCS-1®. PECOME develops verifiable, deliverable oilfield-chemistry solutions for complex and difficult wells, with emphasis on inhibition, lower solids, reservoir protection, reduced dependence on sulfonated and black asphalt materials, and environmentally responsible water-based systems.
FOUNDED IN 1998
A field challenge at the Southern Margin of the Junggar Basin
The Southern Margin of the Junggar Basin had long attracted geological interest. Yet during the 1980s and 1990s, complex formations, wellbore instability, and drilling incidents prevented multiple exploration wells from reaching their target zones. In 1997, the Xinjiang Petroleum Administration proposed a renewed southern-margin campaign and organized research around engineering, drilling fluids, and cementing, seeking technical collaboration nationwide.
In March 1998, Beijing PECOME was established in response to that field need. Guided by the judgment that inhibition should be improved while solids content was reduced, the company proposed the Weigh organic-salt technology route. It progressed into research programs and field trials, and in 2001 supported the first accident-free well to reach its target zone in the southern margin in 20 years. The work subsequently received the Third Prize of Xinjiang Autonomous Region Science and Technology Progress Award. This origin established PECOME's way of working: staying close to customers, tackling technical challenges jointly, and solving practical field problems.
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.
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
NAX50TM 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
For water-sensitive formations, shale oil and gas, and solids-free or low-solids drilling, drill-in, completion, and weighted stimulation fluids, combining density control, strong inhibition, and reservoir protection.
Filtrate Reducers
NAT20® / Redu1® / ReduSH Fluid-Loss Additives
NAT20 is a natural-polymer fluid-loss additive for fresh-water, brine, and high-salinity water-based drilling fluids. It reduces API and HTHP fluid loss, improves filter-cake quality, and limits viscosity build. Redu1 is a carboxy-hydroxy olefin copolymer for systems requiring higher salt tolerance and stability; ReduSH is a modified dextrin additive for brine, organic-salt, and high-density systems, providing fluid-loss control with limited viscosity build.
