| A method for wellbore perforation in which a section of the wellbore to be perforated is isolated and purged of wellbore fluid to provide a clear path for laser beam transmittal. A laser beam emitter in the purged wellbore section transmits a laser beam pulse from the laser beam emitter to a target area of a sidewall and formation lithology of the purged wellbore section, thereby altering a mechanical property of a material of the sidewall and formation lithology and producing material debris. A liquid jet pulse of a liquid is transmitted immediately following termination of the laser beam pulse to the target area, thereby removing the material debris from the target area. This cycle is then repeated until the desired perforation depth has been achieved. | ||||||

| A packer apparatus 102 is disclosed and comprises a body 106 arranged to be disposed in a well casing. An activation member 104 is mounted to body 106 wherein the activation member is moveable relative to the body to deform an elastomeric packer element 108 outwardly relative to the body to form an annular seal in a well casing in use. A plurality of pistons 110 are arranged to move activation member 104 relative to the body. Each piston defines a respective pressure chamber 112 arranged to be filled with fluid in response to an increase in fluid pressure in the body 106 to move each of the plurality of pistons 110 relative to the body 106 and cause the activation member 104 to move relative to the body. | ||||||

| Hydraulic fracturing an individual reservoir fracturing layer of a subterranean formation to produce heterogeneous proppant placement is given in which pillars of proppant are placed such that the pillars do not extend the entire height of the fracture (for a vertical fracture) but are themselves interrupted by channels so that the channels between the pillars form pathways that lead to the wellbore. The method combines methods of introducing slugs of proppant-carrying and proppant-free fluids through multiple clusters of perforations within a single fracturing layer of rock, with methods of ensuring that the slugs exiting the individual clusters do not merge. | ||||||

The invention provides an apparatus and method for perforating and treating multiple intervals of one or more subterranean formations (86) intersected by a wellbore by deploying a bottom-hole assembly having a perforating device (134) and at least one sealing mechanism (120) within said wellbore. The perforating device (134) is used to perforate the first interval to be treated. Then the bottom-hole assembly is positioned within the wellbore such that the sealing mechanism (120), when actuated, establishes a hydraulic seal in the wellbore to positively force fluid to enter the perforations (230, 231) corresponding to the first interval to be treated. A treating fluid is then pumped down the wellbore and into the perforations (230, 231) created in the perforated interval. The sealing mechanism (120) is released, and the steps are then repeated for as many intervals as desired, without removing the bottom hole assembly from said wellbore.

| A method for well construction and completion is disclosed. Generally the method comprises the steps of 1) drilling through an injection zone, 2) positioning an extendable permeable element on the casing capable of stopping formation material from entering the well bore, 3) positioning the casing such that the extendable elements are aligned with the injection zone, 4) extending the member such that they come into direct contact with the injection zone formation, 5) running tubing/completion equipment, and 6) begin injecting the desired fluids into the well. Thus eliminating the need to perforate and gravel pack the well while improving reliability of the injection well completion. | ||||||

| The present invention is an improved method and apparatus for testing and monitoring wellbore operations. The invention is (1) a data acquisition device capable of monitoring, recording wellbore and/or reservoir characteristics while capable of fluid flow control; and (2) a method of monitoring and/or recording at least one downhole characteristic during testing, completion and/or maintenance of a wellbore. The invention includes an assembly within a casing string comprising a sensor probe having an optional flow port allowing fluid flow while sensing wellbore and/or reservoir characteristics. It also includes a microprocessor, a transmitting device, and a controlling device located in the casing string for processing and transmitting real time data. A memory device is also provided for recording data relating to the monitored wellbore or reservoir characteristics. Examples of downhole characteristics which may be monitored include: temperature, pressure, fluid flow rate and type, formation resistivity, cross-well and acoustic sesmometry, perforation depth, fluid characteristic or logging data. With the microprocessor, hydrocarbon production performance may be enhanced by activating local operations in additional associated downhole equipment, e.g., water shut-off operations at a particular zone, maintaining desired performance of a well by controlling flow in multiple wellbores, zone mapping on a cumulative basis, flow control operations, spacing casing and its associated flow ports in multiple zone wellbores, maintaining wellbore and/or reservoir pressure, sensing perforation characteristics, sensing reservoir characteristics or any number of other operations. | ||||||

| Appareil de centrage actionné au fond d'un puits, destinés à center le tubage dans un puits de forage (10) en vue de l'exploration et de la production d'hydrocarbures. Lesdits appareils de centrage (50) actionnés au fond d'un puits sont portés à l'intérieur soit du tubage (60), soit des joints (60), soit des deux et restent généralement en-deçà du profil externe maximal de la colonne de tubage de manière à ne pas interférer avec le déplacement et la mise en place de la colonne de tubage dans le puits de forage. Il est possible de faire effectuer à la colonne de tubage un mouvement rotatif, de va-et-vient et de déplacement, ce qui améliore la capacité de l'installateur à placer la colonne de tubage dans un puits de forage dévié ou de longue distance. Une fois la colonne de tubage en place, les appareils de centrage (50) peuvent être déployés selon un procédé parmi plusieurs, de telle manière que des pistons montés dans des ouvertures situées dans la paroi périphérique de la colonne de tubage se déplacent vers l'extérieur avec suffisament de force pour éloigner la colonne de tubage des parois du puits de forage afin de permettre la formation d'un espace annulaire complet en vue de la cimentation. Une fois le puits de forage cimenté, les fiches dans les pistons tubulaires peuvent être détruites à l'aide d'un procédé parmi plusieurs, ce qui permet d'ouvrir des perforations dans la formation. | ||||||

A well is completed by cementing a casing string (12) in place in the well. A jetting tool assembly (44,46,48) is run into the casing string on a tubing string. The jetting tool assembly engages a sliding sleeve (66) of a casing valve (24) and slides the sliding sleeve to an open position uncovering a plurality of housing ports (56) in the casing valve housing (50) in which the sleeve is received. Then, disintegratable plugs (96) are hydraulically jetted from the housing ports to communicate a subsurface formation adjacent the casing valve with an interior of the casing string. Preferably, prior to opening the sleeve and hydraulically jetting the plugs, residual cement is drilled from the casing string, then further residual cement is hydraulically jetted from the casing valve, and then the casing valve is backwashed by reverse circulation. |
