摘要： Hydrocarbon recovery from subterranean reservoirs that are penetrated by either injector or producer wells is enhanced by selective permeability modification of the strata of the reservoir with gel-forming phenolic compositions. The injection of the phenolic composition follows a pH sequence specific to the reservoir environment which allows emplacement of the gel-forming composition the desired distance away from the wellbore and production of a uniform gel throughout the treated hydrocarbon-bearing reservoir. The permeability of a treated subterranean reservoir can be restored by treatment of the reservoir with either aqueous hypochlorite or mineral acid.

摘要： A polyoxalate containing, as a chief constituent unit, a recurring unit represented by the following formula (1):

-(-CO-CO-O-A-O-) n - (1)

wherein n is a positive number, and
A is a divalent organic group,
and having a quantity of heat of fusion ΔHm of not less than 60 J/g as measured by the DSC in the first time of elevating the temperature and as calculated by the following formula: ΔHm = ΔHm ′ − ΔHc wherein,
ΔHm' is a quantity of heat of fusion (J/g) inclusive of heat of crystallization while the temperature is being elevated, and
ΔHc is a quantity of heat (J/g) generated by the crystallization,
permitting the components to be volatilized in an amount of not more than 2.0% by weight when the temperature is elevated up to 200°C as measured by the TGA, and having a 5% weight loss temperature (Td5%) of not higher than 230°C, and a process for the production thereof. The polyoxalate exhibits a highly hydrolysable capability even at low temperatures, can be excellently crushed, i.e., is capable of effectively preventing itself from undergoing the blocking when it is being crushed.

摘要： The stimulated rock volume (SRV) of a subterranean formation may be increased by pumping viscous fracturing fluid into the formation in a first stage to create or enlarge a primary fracture, decreasing the pumping in order for the fluid to increase in viscosity within the primary fracture, and then continuing to pump viscous fluid into the formation in a second stage. The fluid pumped into the second stage is diverted away from the primary fracture and a secondary fracture is created. The directional orientation of the secondary fracture is distinct from the directional orientation of the primary fracture. The fluid of the first stage may contain a viscosifying polymer or viscoelastic surfactant or may be slickwater.

摘要： A method of increasing the fracture complexity in a treatment zone of a subterranean formation is provided. The subterranean formation is characterized by having a matrix permeability less than 1.0 microDarcy (9.869233 x 10-19 m2). The method includes the step of pumping one or more fracturing fluids into a far-field region of a treatment zone of the subterranean formation at a rate and pressure above the fracture pressure of the treatment zone. A first fracturing fluid of the one or more fracturing fluids includes a first solid particulate, wherein: (a) the first solid particulate includes a particle size distribution for bridging the pore throats of a proppant pack previously formed or to be formed in the treatment zone; and (b) the first solid particulate comprises a degradable material. In an embodiment, the first solid particulate is in an insufficient amount in the first fracturing fluid to increase the packed volume fraction of any region of the proppant pack to greater than 73%. Similar methods using stepwise fracturing fluids and remedial fracturing treatments are provided.
