Product Description

Product Introduction

Crosslinkable PHPA Powder Candidate for Lost-Circulation Control

The TDS describes possible crosslinking with multivalent ions and blocking of formation gaps, but reaction and placement are formulation-specific.

BLUFLOC powder PHPA is described in the supplied family TDS as a water-soluble copolymer of anionic character used in drilling-fluid and selected oilfield applications. The four powder grades span very-high and ultra-high molecular-weight classes with medium or high charge. The table does not assign a unique application to any grade, so the target duty, water, formation, mixing system, and representative test results must decide selection.

Family TDS Screening Overview

4 Grades Comparative screening candidates

89% Min Powder solid content

0.1-0.3% Recommended solution solids

25 kg Lined kraft paper bags

Application Challenges

The TDS describes possible crosslinking with multivalent ions and blocking of formation gaps, but reaction and placement are formulation-specific.
Premature reaction or poor placement in tanks, lines, perforations, or rock.
Injectivity loss, retention, mechanical degradation, or poor filterability.
Formation brine, hardness, iron, oil, temperature, and mineral interactions.

How PHPA Powder Works

The TDS lists blocking, profile control, water plugging, and EOR uses for the PHPA family. Blocking or gel behavior depends on polymer grade, concentration, multivalent ions or crosslinker, salinity, pH, temperature, mixing, contaminants, and residence time. EOR mobility control requires stable hydrated viscosity, injectivity, low retention, shear tolerance, and acceptable produced-fluid behavior.

Molecular-weight and charge classes describe broad polymer behavior, not a guaranteed field result. Powder dispersion, complete hydration, solution concentration, water quality, pH, solids, shear, aging, temperature, and companion chemistry can materially change observed performance.

Important selection note: The grades below are screening candidates, not a fixed prescription. Final grade, solution concentration, process dose, preparation, addition point, and acceptance criteria require current grade documentation and representative laboratory and field or plant trials.

HA8520	Very High	High	Screening candidate; selection requires representative testing
HAA6520	Ultra High	Medium	Screening candidate; selection requires representative testing
HAA7525	Ultra High	High	Screening candidate; selection requires representative testing

TDS confirmation note: Exact active content, viscosity, specification limits, shelf life, and preparation instructions should be confirmed on the current grade-specific TDS and order specification.

Powder Preparation and Dosing Guidance

The supplied family TDS recommends preparing powder PHPA at 0.1-0.3% solids with make-up water at 10-40 degrees C and an effective pH range of 5-14. Efficient dispersion is required; a polymer eductor or commercial dry-powder feeder is suggested. After dispersion into agitated water, continue stirring for about one hour. The TDS notes a propeller-type stirrer at 200-500 rpm and recommends separate stock make-up and solution holding tanks. The prepared anionic solutions are described as stable for up to one week. Aluminum, zinc, copper, and iron should be avoided in the make-up system. Confirm all details against the current grade-specific TDS, SDS, equipment manual, and order specification.

Scale-up warning: Do not scale a laboratory rpm directly to a full tank. Validate impeller, tank geometry, feed distribution, water flow, residence time, shear, and solution quality at the intended production rate.

Application Advantages to Evaluate

Target Application

Potential fit for crosslinkable PHPA powder for lost-circulation control after representative qualification.

Comparative Screening

Four TDS-listed molecular-weight and charge class combinations for comparative screening.

Powder Solids

Powder format with at least 89% solids stated in the family TDS.

Formulation Compatibility

PHPA-family compatibility statement covering biopolymers, PAC, and CMC, subject to formulation testing.

Export Packaging

Palletized 25 kg lined bag format for storage, export, and controlled field make-down.

Recommended Evaluation and Dosing Workflow

STEP 01

Define the leak path, conformance problem, or mobility objective with reservoir and well data.

STEP 02

Characterize formation water, rock, oil, temperature, pressure, and all proposed reactants.

STEP 03

Screen hydration, viscosity, gelation or placement window, filtration, shear, and compatibility.

STEP 04

Run injectivity, core-flow, slot-flow, retention, adsorption, strength, stability, and cleanup tests as applicable.

STEP 05

Use a staged injectivity or field pilot with surveillance and predefined technical and economic criteria.

Product Selection and Compatibility

Characterize the loss path and qualify reaction time, injectivity, strength, stability, and cleanup before field placement.

Compare candidates on polymer solids and achieved operating outcome. Price per bag can be misleading when hydration, make-down losses, dose, equipment throughput, drilling response, fluid recovery, waste, logistics, and downstream costs differ.

Operating Indicators and Troubleshooting

Operating Indicators to Record

Loss rate and aperture
Gel or reaction time
Placement pressure
Strength and stability
Cleanup and remediation

Troubleshooting Note

If performance drifts: Premature viscosity rise in surface equipment requires immediate review of crosslinker contact, water ions, concentration, and residence time.

Packaging, Storage, and Safe Handling

The supplied TDS states that powder products are packed in 25 kg kraft paper bags with inner PE liners and are palletized. Store unopened material in its original packaging in a cool, dry place away from heat, flame, and direct sunlight. The family table states a two-year shelf life for powder products. Protect opened bags from moisture and contamination. Follow the current SDS for personal protection, dust control, spill cleanup, transport, and disposal. Wet polymer is extremely slippery; contain and clean spills promptly.

Scale up only after laboratory acceptance criteria and a controlled field or plant trial have been agreed.

Frequently Asked Questions

Is dry PHPA a complete lost-circulation product?

No. It is a polymer component; a complete treatment may need particles, crosslinker, spacers, and placement design.

Why is slot-flow testing useful?

It can represent flow through a defined opening better than a static beaker gel test.

Is PHPA powder a ready-to-use plugging gel?

No. It is a polymer raw material; a complete formulation and placement design must be qualified.

Does the TDS support a fixed EOR recovery claim?

No. Reservoir response, injectivity, facilities, surveillance, and economics are site-specific.

Qualify Reaction, Placement, Strength, Stability, and Cleanup

Share the target duty, formation and water data, mud formulation, make-down equipment, and proposed test method. Bluwat can help compare the four TDS-listed powder classes under representative conditions.
