摘要： By the method of determining well productivity along a section (2) of a wellbore (1), a gel (7) is injected into the section, so that it gradually fills up the section of the wellbore from a first end (4) to a second end (5). The viscosity of the gel is sufficiently high in order for the gel to form a gel front (6) which travels in a piston-like manner from the first end (4) to the second end (5) and in order for the gel (7) to at least partly plug up pores of the formation (3). A pressure representative of the bottom hole pressure (BHP) in the wellbore is monitored as the gel front (6) travels, and an injectivity index (II) distribution is estimated or determined as a function of the longitudinal position of the wellbore on the basis of the monitored pressure and a gel injection rate.

摘要： Method of detecting a fracture or thief zone in a formation and system for detecting According to the method a fracture or thief zone (1) is detected in a formation (2) surrounding a wellbore section (3) being provided with a non-cemented perforated liner (4). A logging tool (6) provided with at least one temperature sensor (7, 8) is introduced into the non-cemented perforated liner, and a number of temperature measurements and corresponding positions are logged by means of the logging tool, whereby the temperature change over the length of the liner is analysed. The logging tool includes a body (9) provided with an annular flow barrier (10) arranged on the body and extending to the liner, thereby separating the inside of the liner into an upstream section (11) and a downstream section (12). During the logging operation, a fluid having a temperature different from a temperature prevailing in the formation is caused to flow into the liner in the downstream direction.

摘要： A non-cemented liner (20) is introduced into an injection bore (21), steam is fed into the liner at a first bore part (24) and injected into the reservoir through holes (22, 23) in the liner distributed so that the total hole area per length unit of the liner is greater at a second part (25) than at the first part of the bore. Steam enters an annular space between liner and bore only through holes near first part of the bore and subsequently gradually travels inside the liner in direction of second bore part and gradually enters the annular space through holes nearer and nearer second bore part. Gradually liquid is displaced away from an upper liner part and an upper part of the annu!ar space, so that steam contacts the bore along substantially the entire length of the liner in the upper part of the annular space.

The method comprises: collecting field data as a function of time during testing of the well, analysing the collected field data to obtain selected field parameters, providing a created dynamic simulation model of the well inflow profile of the well based on at least the geometry of the well, defining a number of different possible inflow profile scenarios, simulating the defined inflow profile scenarios by means of the dynamic simulation model, analysing the simulated inflow profile scenarios to obtain characteristics of intermittent or slug flow behaviour in the form of selected modelling parameters as a function of time, comparing the selected modelling parameters as a function of time for each inflow profile scenario to the corresponding selected field parameters as a function of time and identifying the most likely inflow profile scenario on the basis thereof, and estimating the well inflow profile along the section of the wellbore based on the comparison of the selected modelling parameters as a function of time to the corresponding selected field parameters as a function of time.

摘要： A wellbore (1) surrounded by a formation has a horizontal section provided with a non-cemented perforated liner (3), thereby forming an annular space (4) between the liner and the formation. The annular space is divided into zones (zone 1, zone 2, zone 3) isolated from each other by means of respective external packers (6, 7, 8) arranged externally on the liner. Selective access to the zones is provided by means of an internal pipe (9) arranged inside the liner and provided with internal packers (10, 11, 12) corresponding to the respective external packers. For each of the zones, the internal pipe is provided with a valve (14, 15, 16) providing access between the inside of the internal pipe and the corresponding zone. Stimulation of the near-wellbore is performed by pumping acid or the like reactive fluid through the internal pipe into the wellbore and is performed simultaneously in adjacent zones of the annular space.

摘要： The sealing device (1) includes an elongated body (5) adapted to be introduced into a tube-shaped channel (2) and including a sealing fluid placement section (6) arranged between a first and a second annular flow barrier (7, 8). The elongated body further includes a sealing fluid activation section (11) arranged between the second annular flow barrier (8) and a third annular flow barrier (12) and including a sealing fluid activation device (13) adapted to at least initiate or accelerate curing of the sealing fluid (17). In operation, the elongated body may be displaced along the tube-shaped channel until the sealing fluid activation section is placed at a position where sealing fluid has been ejected by the sealing fluid placement section, and the sealing fluid activation device may be activated. Thereby, sealing fluid may be cured at selected locations along the tube- shaped channel after ejection of sealing fluid.
