摘要： A method for monitoring waterfront movement in a subsurface formation involves performing forward modeling of at least one deep electromagnetic survey of the waterfront movement, and determining locations for installing an electrically insulating spacer between well liners to form an on-demand electromagnetic source electrode. Based on the forward modeling, repeat survey time intervals are predicted. The method involves, during well completion, installing the electrically insulating spacer between the well liners in a reservoir to form at least one on-demand electromagnetic source electrode, and installing the electrically insulating spacer between the plurality of well liners in a reservoir to form an on-demand electromagnetic receiver electrode. A waterfront survey is performed by conveying a production logging tool into a well that temporarily converts the well liners into an on-demand electromagnetic source electrode and an on-demand receiver electrode, and inverse modeling of the waterfront survey is performed to produce a water saturation image.

摘要： The present disclosure describes methods and systems for detecting a multi-modal tracer in a hydrocarbon reservoir. One method includes injecting a multi-modal tracer at a first location in a reservoir, wherein the multi-modal tracer mixes with subsurface fluid in the reservoir; collecting fluid samples at a second location in the reservoir; and analyzing the fluid samples to detect a presence of the multi-modal tracer in the fluid samples.

摘要： A wellbore that supplies production fluid from a first production zone and a second production zone is produced. Production fluids from the first and second production zone are comingled within a same production tubular. A first tracer is pulsed into the first production zone. A second tracer is pulsed into the second production zone. The first tracer and the second tracer are barcoded such that the first tracer and the second tracer can be differentiated from one another. A first tracer decay is measured at a topside facility. A second tracer decay is measured at the topside facility. A water cut of the first production zone and the second production zone is determined based upon the first tracer decay and the second tracer decay.

摘要： A technique of utilizing waste as an interwell tracer. The waste includes pharmaceutical, personal care product (PPCP) waste or nanoplastic (NP) waste, or both. The system and method includes injecting an injection fluid including water and the waste at an injection well into a subterranean formation, producing produced fluid including water at a production well from the subterranean formation, measuring concentration of the waste in the produced fluid, and comparing the concentration of the waste in the produced fluid with the concentration of the waste in the injection fluid.

摘要： Historical production data associated with production of a hydrocarbon product in a reservoir is obtained. Historical tracer test data associated with the production is obtained. History matching is performed using the historical production data and the historical tracer test data to generate improved geological models. Production optimization is performed using the improved geological models, including predicting optimized controls and updating, using the predicted optimized controls, water injection rates and fluid production rates for individual injectors and producers. The predicted optimized controls are applied to the reservoir to optimize future production.
