Definitions
- Canadian Patent 972,141 to Sullivan discloses a well drilling fluid containing ground particles of uintaite (gilsonite) pre-coated with a non-ionic surfactant to make the particles water-wettable.
- Preferred surfactants are phosphate esters-derived from the group consisting of polyoxyethylene ethers of organic compounds containing at least 6 carbon atoms and having a reactive hydrogen and condensed with at least 3 mols of ethylene oxide.
- a process for using this composition in well drilling operation is also disclosed.
- Softening points of uintaite generally depend on the source or vein where the uintaite is mined.
- the high softening point uintaite has a softening point of at least 360° F., preferably 375° F., or higher.
- Preferred high softening point uintaite has a softening point of from about 370 to 390° F.
- the lower or low softening point uintaite has a softening point of about 330° F, or lower.
- Preferred low softening point uintaite has a softening point of from 290-330° F., preferably about 325° F.
- the softening points of the two uintaites are preferably at least 40° F. apart, more preferably about 50° F. apart or more.
- upgraded uintaite could be used to replace or partially replace the low softening point uintaite.
- Uintaite can be upgraded by solvent extraction or precipitate to give lower softening point products.
- Preferred weight ratios of the high softening point uintaite to the lower or low softening point uintaite are in the range of 4:1 to 1:2, more preferably in the range of 3:1 to 1:1, and most preferably about 2:1.
- the mixture of uintaites is made up of about a 2:1 mixture of Gilsonite® HM, having a softening point of about 380° F, and Gilsonite® Select, having a softening point of about 325° F.
- the ratio of Gilsonite® HM to Gilsonite® Select to lignite is about 2 to about 1 to about 1.
- Preferred surfactants are highly lipophilic non-ionic surfactants.
- ⁇ highly lipophilic ⁇ surfactant is meant a surfactant that has a strong affinity for a hydrocarbon phase, rather than water.
- the relative contribution of the non-polar lipophilic tail to the polar hydrophilic head is high.
- Preferred surfactants have at least 80% of their molecular weight in the hydro-phobic or lipophilic tail, preferably about 90% or more.
- Non-ionic surfactants having HLB values below about 3 include high molecular weight fatty alcohols, such as cholesterol and lanolin alcohols; ethoxylated polyoxypropylene glycols, such as Alkatronic PGP 33-1 and PGP 18-1; ethoxylated amines, such as those sold by Tomah Products Inc.; block copolymers of propylene oxide and ethylene oxide, such as those in the Tetronic series; and ethoxylated ethylene diamine polyoxypropylene compounds, such as Alkatronic EDP 38-1 and EDP 28-1. Mixtures of surfactants are also envisioned.
- high molecular weight fatty alcohols such as cholesterol and lanolin alcohols
- ethoxylated polyoxypropylene glycols such as Alkatronic PGP 33-1 and PGP 18-1
- ethoxylated amines such as those sold by Tomah Products Inc.
- block copolymers of propylene oxide and ethylene oxide such as those in the Tetron
- A Pluronic L-101, a 10% ethylene oxide polyoxypropylene-polyoxyethylene block copolymer, MW TM 3800; BASF Wyandotte, New Jersey.
- HTHP high temperature/high pressure
- Berea core test provided data that could be used to discriminate between various additives. The procedure of this test is described in SPE Paper 17203 to Davis & Tooman, presented Feb. 28-Mar. 2, 1988, pp. 235-246. Additives were tested in a caustic water-based drilling mud. The tests indicate that temperature and pressure influence the depth of intrusion of different softening point uintaites. It is desirable to obtain some intrusion, but not a deep depth of intrusion, i.e., about 1 mm of intrusion. In addition, some intrusion of the material is necessary. (See page 243, Table #6, PE 17203.)
- additive E is superior to the other drilling mud additives tested, performing effectively over a wide temperature range.
- This additive is superior at both low temperatures and high temperatures when compared to asphalts and additives containing a single softening point uintaite.
- the continuing good performance of this additive depends on using the fight surfactants, that is those with strong affinities for the unitaite, such as Pluronic L-101.
- the FSCOT chromatograms of the solvent extract of a drilling mud sample containing our additive showed low levels of hydrocarbons all the way out to the C-40 components.
- the heavy-end components (C-28 to C-38) show the familiar FSCOT pattern of uintaite. Any surfactant in the sample is generally represented by the lighter hydrocarbons (C-8 to C-20) in the chromatogram.
