Drilling Fluid & Cuttings Recycling Patent Snapshot
The indexed corpus for drilling fluid and cuttings recycling is extremely small, comprising 4 patent families, all attributed to a single applicant, Quanta Associates LP. Filing activity was concentrated in 2018, with no recorded filings in subsequent years, indicating either a narrow search scope or a nascent, lightly contested technology niche.
Quanta Associates LP holds the entire indexed corpus
Quanta Associates LP is the sole ranked applicant, accounting for all 4 patent families in scope. No secondary or challenger applicants appear in the ranking, making this one of the most concentrated patent positions observable.
With one applicant holding 100% of the ranked applicants visible in this query’ combined total, there is no meaningful tier gap — the field as indexed has a single occupant. This level of concentration is unusual and likely reflects a narrow corpus definition rather than the full breadth of adjacent oilfield-technology IP.
| # | Applicant | Patent families | Share |
|---|---|---|---|
| 1 | Quanta Associates LP | 4 |
Quanta Associates LP’s position, however small in absolute terms, implies unchallenged IP control within the indexed scope. Any entrant seeking freedom to operate in this exact technology definition would need to evaluate these 4 patent families directly.
The most recent filings fall in 2018; given standard publication lags, the absence of activity through 2026 in this corpus may reflect scope limitations rather than a genuine halt in industry investment. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A single filing cohort in 2018 defines the entire trend
All 4 patent families were filed in 2018; no filings are recorded in any other year within the 2017–2026 window. The technology composition is split evenly between materials science and drilling-engineering classifications.
Annual filing trend
The trend line shows a single spike of 4 families in 2018 and zero activity in all other years. Given publication lags of 18–24 months, the 2024–2026 period should be treated as potentially under-counted, but the overall pattern — a discrete 2018 cohort — is unlikely to change materially.

The corpus splits equally across C09K (materials for miscellaneous applications, covering fluid chemistry) and E21B (earth and rock drilling, covering well and borehole mechanics). This dual classification is consistent with integrated drilling-fluid recycling inventions that address both chemical formulation and mechanical handling.

Working an underground arcuate path around at least a portion of an obstacle with a casing extending into the underground arcuate path, connecting a rotating control device to the casing; and a Venturi device connected to the rotating control device. (excerpt from the patent abstract)
Ranked by total forward citations. Citation counts favour older and broadly cited patent families, and broad or adjacent patents may appear when they match the search scope. Treat this section as citation context, not as a curated list of the most topic-specific patents. Some patent titles may be shown in their original, non-English language where an accurate translation could not be guaranteed.
Assignee snapshot from the current evidence set
The applicants below are visible in this query result. Because the evidence set is relatively small, read this section as a directional snapshot rather than a full competitive ranking.
Quanta Associates LP
Quanta Associates LP holds all 4 patent families in scope, covering both C09K 8 (fluid chemistry and materials) and E21B 15 and E21B 17 (drilling mechanics and equipment). All activity is concentrated in 2018; no momentum data is available for subsequent periods, making trajectory assessment not possible from current evidence.
families: 4No challenger identified
No second-ranked applicant appears in the indexed corpus. This card will be populated if the search scope is broadened to include adjacent drilling-fluid treatment, waste management, or solids-control technology classes where additional applicants are likely present.
families: —Frequently asked questions
The indexed corpus contains 4 patent families. This is a very small corpus and likely reflects a narrow search definition; broadening the scope to adjacent IPC classes would be expected to surface additional filings.
Quanta Associates LP is the sole ranked applicant, holding all 4 patent families in the indexed corpus. No other applicants appear in the ranking.
Australia leads with 2 patent records, followed by Canada with 1 and WIPO (PCT) with 1. The United States and European jurisdictions do not appear in the current corpus.
The corpus is classified under two branches: C09K (materials for miscellaneous applications, covering fluid chemistry) and E21B (earth and rock drilling, covering borehole and well mechanics). Each branch accounts for 4 records, reflecting dual classification of the same families.
All 4 patent families were filed in 2018. No filings are recorded from 2019 onward in this corpus. Given publication lags, the most recent period may be under-counted, but the overall pattern is a discrete 2018 cohort with no subsequent indexed activity.
No co-applicant or collaboration relationships are recorded in the current corpus. All 4 patent families are attributed solely to Quanta Associates LP with no academic, consortium, or joint-venture co-filers identified.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown.
