Fracturing Chemicals
Hydraulic fracturing is the process of pumping fluid such as water and guar slurry, with a material (most commonly proppant) under high pressure into a hydrocarbon containing formation to stimulate production from new and existing oil and gas wells. When done correctly, a fracture in the formation is created that is unable to close improving the paths for oil and gas to flow. This radically increases the rate for at which oil and gas is produced from the formation, whereby production at an economic rate would not take place otherwise. Although hydraulic fracturing has become a very common process the use of best in class fracturing chemicals is vital in the success of any hydraulic fracturing process.
Drilling Fluid Additives
There are many drilling fluid systems available it todays exploration efforts including but not limited to water-based, oil-based, synthetic based, and clay free. Special additives are used in these drilling fluid systems to provide a host of functions that are essential to the fluid having the correct physical and performance properties needed at a particular time based on drill bit depth.
Acid Additives
Matrix and fracture acidizing of sandstone and carbonate reservoirs are techniques for stimulating oil and gas reservoirs to produce at higher rates. Acids dissolve rock or permeability damaging fines near the wellbore. Successful acidizing requires a working knowledge of formation damage, acid chemicals, and the mechanics of acid stimulation techniques.
Production Chemicals
Time and technology has afforded the industry many data points and trends in particular shale plays pertaining to production chemical needs based on oil properties, water characteristics, production data, water cut, gas analysis, etc. That being said, every well is unique and brings about its own set of challenges pertaining to corrosion and scale tendencies, emulsion characteristics, paraffin deposition, degree and speed of liquid loading, etc. To address the common too the most unique production chemical needs there must be an arsenal of performance leading chemistries available and APChem® is a leading manufacturer of those chemistries.
Cementing Additives
Well cementing is the process of creating a cement slurry and pumping it through steel casing to critical points in the annulus or in the open hole below the casing string. Common types of cementing applications include conductor or surface casing, intermediate string casing, production string casing or production liner, squeeze, and plugging. Each job's success lies in the performance of the additives incorporated into the cement slurry along a thorough understanding of the dynamic forces at work at surface and downhole.
