LOWER ECCA SHALE D . T . A . CURVES - A THERMO - DY NAMlC INTERPRETATION

نویسنده

  • J. A. DRENNAN
چکیده

Typical D.T.A. peak systems yielded by the fresh lower Ecca shales in the Durban and Pietermaritzburg areas are presented. The theoretical course of recrystallisation for these rocks is derived from chemical thermodynamic data. These theoretical results agree well with experimental observation. Carbon is found to dictate the course of recrystallisation on the basis of overall chemical rather than detailed mineralogical composition.

Thermo-sensitive polymer nanospheres as a smart plugging agent for shale gas drilling operations

Emulsifier-free poly(methyl methacrylate-styrene) [P(MMA-St)] nanospheres with an average particle size of 100 nm were synthesized in an isopropyl alcohol-water medium by a solvothermal method. Then, through radical graft copolymerization of thermo-sensitive monomer N-isopropylacrylamide (NIPAm) and hydrophilic monomer acrylic acid (AA) onto the surface of P(MMA-St) nanospheres at 80 °C, a seri...

Coupled Thermo-Hydro-Mechanical-Chemical Modeling of Water Leak-Off Process during Hydraulic Fracturing in Shale Gas Reservoirs

The water leak-off during hydraulic fracturing in shale gas reservoirs is a complicated transport behavior involving thermal (T), hydrodynamic (H), mechanical (M) and chemical (C) processes. Although many leak-off models have been published, none of the models fully coupled the transient fluid flow modeling with heat transfer, chemical-potential equilibrium and natural-fracture dilation phenome...

The influence on casing stress for shale gas fracturing wells considering thermo-pressure coupling effect

The casing deformation problems are presented over 36 wells (among 112 horizontal wells by 2016) during fracturing processes in Weiyuan-Changning shale gas play in China.1 Subsequent tools could be blocked in the wellbore.2–4 The segments with serious deformation had to be abandoned before completing fracturing operations.5 The casing deformation issues make a great influence on production of s...

XRCC1 Arg194Trp and Arg399Gln polymorphisms and risk of extrahepatic cholangiocarcinoma: a hospital-based case-control study in China.

BACKGROUND Extrahepatic cholangiocarcinoma (ECCA) is a rare but devastating malignancy. Up to 90% of patients presenting with ECCA have no identifiable risk factors. The base excision repair (BER) pathway has a principal role in the repair of mutations caused by oxidized or reduced bases. The XRCC1 is one of the key proteins in the BER pathway. In this study, we investigated the influence of XR...
