Badania nad unieszkodliwianiem ścieków kopalnianych towarzyszących surowcom węglowodorowym
(2006) Konopka, Elżbieta; Lewkiewicz-Małysa, Aleksandra
Waste mine's water produced during oil and natural gas exploitation are to varying degree (highly) mineralized with chlorine and sodium brines. Considerable quantities of specific organic substances and a charge of hardly settling suspension are present in the mine's water. This waste needs treating to such a degree that it can be disposed to water courses or injected into the rock mass. Laboratory analyses of two exemplary waste samples were targeted at the efficiency of the coagulation-flocculation method in view of degree of contamination. The analyses were aimed at determining possibilities and limitations of methods of removing components of waste which have a negative environmental influence on surface waters and rock mass.

Flokulacja suspensji ilastych i płuczek wiertniczych z zastosowaniem nowo opracowanych flokulantów kationowych
(2009) Wysocki, Sławomir; Wysocka, Marta; Bielewicz, Danuta
The authors present the results of lab tests on new synthetic cationic flocculants PT-floc-201107 which are used to reduce volume of bentonite suspensions and drilling mud. The optical method was used to investigate the mud flocculation process and moving time of the phase separation boundary. The lab tests indicated that the PT-floc-201107 polymers are suitable for phase separation of drilling mud and aqueous suspensions of silty minerals which are rather difficult to separate.

Flokulacja suspensji ilastych i zasolonych płuczek wiertniczych z zastosowaniem nowo opracowanych flokulantów kationowych (PT-floc-201107)
(2010) Wysocki, Sławomir
The paper presents the results of lab tests on new synthetic cationic flocculants PT-floc-201107 which are used to reduce volume of bentonite suspensions and salted drilling mud. The optical method was used to investigate the mud flocculation process and moving time of the phase separation boundary. The lab tests indicated that the PT-floc-201107 polymers are suitable for phase separation of drilling mud and aqueous suspensions of silty minerals which are rather difficult to separate.

Techniczne i technologiczne aspekty zatłaczania wód złożowych do górotworu

Reservoir water injection to the rock mass through disposal wells should meet mining and environmental safety requirements. This problem is of special significance in the case of wells that are either abandoned wells or to be closed. The selection criteria for disposal wells and range of necessary tests and analyses of post-exploitation wells' construction designed for injection of reservoir water are presented in the paper. The results of laboratory analyses of reservoir water of known physicochemical properties were used for determining and eliminating original factors favorable to the colmatation of the near-well zone. KEYWORDS: reservoir waters, injection zones, water treatment, sedimentation, flocculation, colmatation, near-well zone.
