This temperature range covers most applications in drilling fluids. The method of claim 8 where in providing the water-based drilling fluid, the polymer latex is present in the drilling fluid in an amount of from about 0. In previous tests the circulation was stopped after an hour, baoer the plug started leaking again after another 30 hours.

With the drop in differential pressure, the fludis is no longer supported and can easily break off and fall into the well bore. Another characteristic of EXP is that its ultra-fine particles are elastomer-like over a wide range of temperatures. Invert emulsion fluids formulated with traditional diesel, mineral or the newer synthetic oils are the highest performing drilling fluids with regard to shale inhibition, borehole stability, and lubricity. The plug is oriented with the bedding planes in the parallel or high permeability direction.

The method of claim 9 where the salt is present in the drilling fluid in an amount of from about 1 wt. First, the ultra-fine, deformable latex particles having a preferable diameter of about 0. These results verify the necessity of having all three components: It would be desirable to be able to reduce the loss of drilling fluid into depleted sands.

The pressure in each accumulator is controlled with a manual regulator fed by a psi 15, kPa nitrogen bottle. Additional evaluations were performed only for those samples having passed the above screening test. Report on drilling fluids Documents. Drilling and Completion Fluids Engineering.

Search Expert Search Quick Search. If added to mud formulations earlier, they tend to be unstable and precipitate prematurely. Msnual comparative Examples undesirably gave increasing formation pressures over time. Ause of salt only comparative Ex. The sulfonated latexes of the present invention have an added advantage in that they can often be used in the absence of a surfactant. This static period eliminates pressure drift due to temperature effects by allowing tluids variation from circulation to equilibrium.

Aluminum Complex Although a synergistic effect of ALPLEX with latex on stabilizing shales was confirmed by PPT test results, this system is fragile and very sensitive to increasing salt concentration and temperature.

It is desired that the sodium aluminate or other precipitating agent be in a metastable form in the mud, which means that it is in suspension or solution, but precipitates out upon the borehole wall. Click for automatic bibliography generation. Formation Pressure Inteqq, hours: The proportion of the polymer latex in the drilling mud, based on the total amount of the fluid may range from about 0.

The shale inhibition characteristics were determined by shale dispersion tests that included static wafer test, and pore pressure PPT tests. Inhibiting drilling fluid pressure invasion into the wall of drillinb borehole is one of the most important factors in maintaining wellbore stability. The optional salt may be any common salt used in brine-based drilling fluids, including, but not necessarily limited to calcium chloride, sodium chloride, potassium chloride, magnesium chloride, calcium bromide, sodium bromide, potassium bromide, calcium nitrate, sodium formate, manua, formate, cesium formate and mixtures thereof.

Pressure is plotted versus time.

Latex Stability As noted above, initial experiments indicated that some latex products emulsion polymers produced synergistic effects with an aluminum complex, resulting in improved pore pressure transmission characteristics of the fluids.

The salt and polymers were then added. A rubber sleeve is placed around the core and the pistons to seal around the core and prevent flow around the core. 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. Observe sieve for amount of retained latex particles. The low pressure side of the core formation side is fitted with a 1 liter, psi.

As indicated the Inventive Examples 5 and 6 both gave the desired results of decreasing formation pressure over time. Suitable precipitating agents include, but are not limited to, silicates, aluminum complexes, and mixtures thereof. However, latex is generally considered to be a metastable system.

Unless otherwise noted, the latex in the Examples is Latex, a polyvinylacetate latex. Practical Drilling Fluids Documents.

These attributes include shale inhibition reduced pore pressure transmissioncuttings integrity, high rates-of-penetration, and reduced torque and drag reduction.

Methods of sealing subterranean zones. LD8 was added to control foaming.
