摘要： Methods and systems for determining a liquid level in a formation between a horizontal segment of an injection wellbore and a horizontal segment of a production wellbore are disclosed. Under shut-in conditions, local temperatures and pressures are determined for each of a plurality of inflow zones along the production wellbore segment. Local profile values are determined based on local shut-in subcool values and local shut-in liquid levels. After flow has resumed, a local liquid level is determined based on the local operating subcool value and the local profile value for that inflow zone. The local profile values may be updated during subsequent shut-ins.

摘要： Methods and systems for determining a liquid level above a horizontal segment of a wellbore in a formation are disclosed. Local temperatures and pressures are determined for each of a plurality of zones along the wellbore segment. For each zone, a local inflow rate is determined for fluids entering the wellbore from the formation. Based on the local inflow rate, local temperature, and local pressure, a local reservoir pressure is determined, and a local liquid level is determined based on the local reservoir pressure and a pressure associated with an injector wellbore positioned above the horizontal segment.

摘要： Methods for injecting a fluid into a subsurface formation are provided. Each of the methods includes the obtaining data, including formation parameters and operational variables, related to an injection well. A regime of operation for the injection well is determined. The regime of operation is determined using a heuristic model. In one aspect, one or more operational variables, including completion design, reservoir development procedures, and/or injection procedures, is designed based at least in part on the determined regime of operation. Water or other fluid may then be injected into the subsurface formation. The step of determining the regime of operation for the injection well may use a full physics computational simulation to construct a mathematical model that can estimate the operating regime for the water injection well. Alternatively or in addition, field data may be used.

摘要： A method associated with the production of hydrocarbons is described. The method includes drilling a wellbore using a drilling fluid, conditioning the drilling fluid, running a production string in the wellbore and gravel packing an interval of the wellbore with a carrier fluid. The production string includes a joint assembly comprising a main body portion having primary and secondary fluid flow paths, wherein the main body portion is attached to a load sleeve assembly at one end and a torque sleeve assembly at the opposite end, the load sleeve assembly having at least one transport conduit and at least one packing conduit disposed therethrough. The main body portion may include a sand control device, a packer, or other well tool for use in a downhole environment. The joint assembly also includes a coupling assembly having a manifold region in fluid flow communication with the second fluid flow path of the main body portion and facilitating the make-up of first and second joint assemblies with a single connection.
