n pi: special conditions or additional requirements that are attached to permits to drill, deepen, or plug back. These conditions range from administrative matters, such as the frequency and number of required reports, to technical or environmental conditions, such as requirements for drilling mud disposal. In all cases, these are specific conditions that amplify or explain a requirement in OCSLA, MMS regulations, OCS Orders, or lease stipulations.

n: the dispersion of solids that have stuck together in drilling fluid, usually by means of chemical thinners. See flocculation.

n: (1) The process of thinning the drilling fluid by bonding with (neutralizing or covering) the positive electrical charges of drilling fluid additives to prevent one particle of drilling fluid from being attracted to another particle. (2) Breakup of flocs

dispersing a clump or a gathering or “flocculated” of particles. Usually accomplished by dispersants or solvent thinners.

n: a plan required by the MMS before development and production can take place in the OCS. The MMS approves or disapproves the plan based on environmental, technical, and economic considerations.

fluids with materials added to disperse solids or flocs.

n: a plan required by the MMS before exploration can take place in the OCS. The plan must include measures to protect the environment. The MMS reviews the plan, analyzes the environmental effects, and determines any appropriate mitigating measures before approving the plan.

abbr: flocculates.

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.

n pi: special stipulations, or requirements, that are often included in OCS oil and gas leases in response to concerns raised by coastal states, fishing groups, federal agencies, and others. The stipulations may require biological surveys of sensitive seafloor habitats, environmental training for operations personnel, special waste-discharge procedures, archaeological resource reports to determine the potential for the encounter of historic or prehistoric resources, special operating procedures near military bases or their zones of activity, and other restrictions on OCS oil and gas operations. Lease stipulations are legally binding, contractual provisions.

integrated workover control system.

n: the waste procsee system produced by Swaco compony in American.
