The invention will be further illustrated with respect to the hughess examples, which are only meant to further illuminate the invention, and not limit it in any way.
The shale inhibition characteristics were determined by shale dispersion tests that included static wafer test, and pore pressure PPT tests. The method of claim 8 where in providing the water-based drilling fluid, the water comprises salt. Photomicrographs of the plug face showed latex accumulation along microfractures in the shale. In fact the term under-balanced drilling Documents. As indicated the Inventive Examples 5 and 6 both intew the desired results of decreasing formation pressure over time.

Optimizing high performance water base mud design is commonly at the forefront of many drilling fluid service and oil operating companies’ needs due to the various limitations of invert emulsion fluids.
The method of claim 8 where in providing the water-based drilling fluid, the polymer latex comprises particles that average less than 1 micron in size.
Another optional component is precipitating agent. EXP Oleamidopropyl betaine surfactant.
These attributes include shale inhibition reduced pore pressure transmissioncuttings integrity, high rates-of-penetration, and reduced torque and drag reduction. Among the tested samples, EXP exhibited the best compatibility with this latex system. Oil base drilling fluid composition. A Malvern Mastersizer Particle Size Analyzer was used to measure the particles size distributions of latex in formulated fluids.

Shale has a very low permeability, so the flow of fluid through it is very small. Published on Jan View 70 Download Suitable wetting surfactants include, but are not limited to, betaines, alkali metal alkylene acetates, sultaines, ether carboxylates, and mixtures thereof.
The first of these referencf was tested on the PPT test in a fluid with other products. The proportions of these components based on the total water-based drilling fluid are from about 0. Since the development of pore pressure transmission PPT testing, the effects of various chemical additives on pore pressure transmission rates have been evaluated.
It has been determined that surfactants are particularly beneficial when salts are present in the drilling fluid, intdq are not as preferred in fresh water fluid systems. Drilling Fluids Processing Handbook Pdf handbook,drilling fluids processing handbook,drilling fluids processing handbook Typically, the water present contains a salt to form a brine, often to saturation, although the invention may be practiced with fresh water.
The method of claim 8 where in providing the water-based drilling fluid, the precipitating agent is present in the drilling fluid in an amount of from about 0. High Temperature High Pressure Fluid loss at psi and. Observe the fluid for flocculation and separation.
Poor solubility and slow dissolution drillinb of the lignite in high salt concentrations is probably the main factor contributing to decreased latex stability. The large surface of the particles is thermodynamically unstable and any perturbation affecting the balancing forces stabilizing the polymer dispersion results in a change in the kinetics of particle agglomeration.
Suitable precipitating agents include, but are not limited to, silicates, aluminum complexes, and mixtures thereof.
Drilling and Complwtion Fluids Documents. Various limitations of these fluids, however, such as environmental concerns, economics, lost circulation tendencies, kick detection, and geologic evaluation concerns maintains a strong market for high performance water based fluids.
The fluid of Example 1 was used. Oil can be emulsified in the water or brine. Two other inventive formulations Examples 5 and 6 and six comparative Examples A-F were prepared and tested. However, latex is generally considered to be a metastable system. It can be clearly observed that the referencs filter cake was formed inside of the 50 mD disk.
The differential pressure consolidates the latex deposit into baier solid seal. The method of claim 8 where in providing the water-based drilling fluid, the surfactant is selected from the group consisting of betaines, alkali metal alkylene acetates, sultaines, ether carboxylates, and mixtures thereof. The pressure increase in the formation piston water is measured as formation pressure FP rise.
