n: A chemical that causes a dispersed colloidal system (such as clay) to coagulate and form flocs. Most flocculants are either multivalent cations such as calcium, magnesium and aluminum, or long-chain polymers. High pH, high salinity and high temperature ca

Materials used to increase visicosity. They cause colloidal particles to group into bunches or flocs.

reservoirs that occur along ancient rivers where the rivers overflowed. Deposits are mostly silt and mud.

n: those workers on a drilling or workover rig who work primarily on the rig floor. See rotary Mlper.

n: the drilling crew or clean crew who work in the drilling platform alternately

a science field dealing with prevention of scales, hydrates, asphaltene and paraffin deposits and other problems that could stop flow of fluid from the subsurface, wellhead or pipeline.

n: 1.The predominant flow geometry reflected in a pressure-transient response that is most easily recognized in the log-log presentation of the pressure-change derivative. The most easily recognized flow regime is radial flow, which produces a constant or fl

flow condition (e.g., mist, slug, churn, etc.) of a multiphase process stream.

a multipoint flow test measuring skin at each flow rate. When plotted, the intersection of the best fit line with the y-axis (skin) at zero flow rate yields the mechanical skin.

n: a kind of optics analysis method in which substance contant can be measured according the intensity of fluorescent emitted by some substance under the beaming of ultraviolet ray

n: the area near the wellbore where invading mud filtrate forces out the movable formation fluids. Often abbreviated Rxo

part of the rock that has been flushed with a sweep fluid. The area may have little hydrocarbons remaining.

n: a type of rock consisting of thinly bedded sandstone and shale, thought to be the result of the action of turbidity currents;a succession of turbidites originating in marine depositional basins, usually near the base of the continental slope. Flysch deposites are especially common in the Alpine region of Europe.

n: a two-phase system, similar to an emulsion, in which the dispersed phase is a gas or air.

n: the dispersed material which forms through the insolubility gas dispersing in the fluid or melt solids

a gas in liquid emulsion. Common as a low density cleanout fluid or a frac fluid with reduced water content.
