This editorial policy explains how drillingfluidadditives.com stays independent of the companies it writes about, where its facts on drilling fluids and their additives come from, how requests are disclosed and how errors are corrected.
The Drilling Fluid Additives Editorial Team writes and maintains every page and appears as the byline on each one. No named expert is credited, and no page claims review by an outside specialist. A page rests on the sources named inside its own sentences.
In order, this page states that no company pays for placement, that standards and regulators outrank supplier data, that every figure carries its source and date, that forwarded requests are disclosed in fixed words and that errors go to one mailbox.
Standards and regulations are checked against their issuing bodies, product values against the named data sheet and figures against the dated source named in the sentence; see our methodology and fact-checking.
Editorial Independence: No Company Pays for Listings, Rankings or Pages#
No company pays to be listed, ranked or written about on this site, and no page carries advertising or sponsored content. Content decisions rest with the editorial team alone, and the site publishes no supplier rankings.
The site is funded by forwarding the quote and service requests readers send through its forms. Forwarding a request never changes what a page says, and no analytics or advertising vendor is loaded on the site.
Companies are described from public facts, never ranked. Readers comparing drilling fluid companies work from stated criteria, so the choice stays with the reader.
Which Standards, Regulators and Papers Every Page Is Compiled From#
Every page is compiled from named primary sources: standards bodies, regulators, public statistics, peer-reviewed and conference papers, and supplier data sheets as product examples. The standards bodies are API and ISO, and the regulators are the US EPA through the eCFR, OSPAR, Cefas, Miljodirektoratet and ECHA.
The table below shows which source type supplies which kind of value.
| Source type | Examples | What it may supply | Label |
|---|---|---|---|
| Standards bodies | API, ISO, IADC as a standards publisher | Requirement values, test conditions, editions | Standard, edition and date |
| Regulators and official registers | eCFR (US EPA rules), OSPAR, Cefas, Miljodirektoratet, ECHA | Discharge limits, notification status, hazard classification | Instrument and section, list update |
| Public statistics | USGS Mineral Commodity Summaries | Supply shares, unit values (never a price today) | Year and "estimated" |
| Papers | SPE (OnePetro), AADE conference papers, peer-reviewed journals | Test results, field data | Paper number or authors and year |
| Analyst reports | Named market publishers | Market size estimates only | Publisher and year, "estimate" |
| Supplier data sheets | One named product | One product's typical value, never a requirement | Product and company, "data sheet" |
IADC appears as a standards publisher for its drilling fluids manual and unit factors. Company glossaries, product pages and field guides serve as background and are never cited in the text.
Rules come from the instrument itself, not from a summary of it. The instruments behind the drilling fluid standards and rules are API, ISO, EPA and OSPAR texts, read at the clause or section named in the sentence.
Standards and regulators before supplier data sheets#
A standard or regulation outranks a supplier data sheet: an API or ISO value is a requirement, while a data-sheet value is one product's typical value and is always labeled with that product's name and source. A newer official source replaces an older record, and the page is updated. One product's temperature limit is never presented as the limit of a whole class.
These pages are a reference, not a well design. A drilling fluid program follows the operator's specification, the applicable standard edition and the product SDS. Hazard lines follow the harmonized CLP entry where one exists, else the majority ECHA notification, else "see supplier SDS".
How Figures Are Cited, Dated and Checked#
Every figure is cited inside its sentence with its instrument and date, for example API RP 13B-1 (6th edition, January 2026), 40 CFR 435.13 or OSPAR Agreement 2013-06, Update 2026. An API Spec 13A value names the edition with its addenda and errata, and the edition check date comes from the API Standards Plan. ISO 13500 is named as the ISO counterpart of API Spec 13A. API Spec 13A requirement values for bentonite, attapulgite, sepiolite, carboxymethyl cellulose, starch, polyanionic cellulose and xanthan gum carry the label "18th edition (2010) text". Public-record values from USGS Mineral Commodity Summaries 2026 carry the year and the word "estimated" where the source estimates them, and are never presented as a price today. A market size appears only as a named analyst estimate with publisher and year.
Units run oilfield first with SI in brackets, for example 1 lb/bbl (2.853 kg/m3), and every temperature appears in degF (degC), for example 250 degF (121 degC). Each figure is checked and re-checked as set out in the methodology and fact-checking description, and an item that cannot be confirmed at its source is left out, not hedged.
How Quote and Service Requests Are Disclosed#
Requests sent through the supplier quote form and the service match form are forwarded to independent suppliers and service providers, and every form says so in the same words. The disclosure reads: "Requests are forwarded to independent suppliers and service providers. No company pays to be listed or ranked here; see the editorial policy."
The two forms are headed "Request supplier quotes" and "Find drilling fluid support". They name no company that receives a request and promise no response time and no number of quotes or replies. A request never changes what a page says.
Form submissions are kept for 24 months.
Corrections Policy: How to Contact the Editors About an Error#
Errors are reported by email to editorial@drillingfluidadditives.com, and each report is checked against the primary source the page cites. A report that follows four steps can be checked fastest.
- Write to editorial@drillingfluidadditives.com with the page URL.
- Quote the sentence or table cell.
- Name the source that shows the correct value: standard and edition, regulation and section, or paper.
- Add whether you write for a company named on the page.
A confirmed error is corrected on the page. A change to a requirement, limit or edition follows the current text of the issuing body.
Companies and rights holders use the same route as readers. They reach the editorial team through the contact page, and a request to change a ranking or add a promotion is declined, because the site ranks no company.
Company Names and Product Examples#
Company and brand names appear on this site only as market facts or as the named source of one product value, never as an endorsement. A product example states the product and its company and is labeled as that product's typical value from its data sheet. Class pages and hubs carry no product values.
The label "API 13A grade" is used only for the 13 materials API Spec 13A covers, never for another product.
Editorial Policy, About and Privacy: The Site's Trust Pages#
This editorial policy works together with the about, methodology, contact and privacy pages, which describe who publishes the site, how figures are checked, how to reach the editors and how personal data is handled.
Form data, retention and rights are described in the privacy policy.
How outbound links are followed or nofollowed#
Links to government, intergovernmental and standards bodies and to peer-reviewed publishers are followed; every other outbound link, supplier data sheets included, is nofollow.
A nofollow link is a citation, not an endorsement, and no outbound link is paid for.
